A quick look at some of the best straight pull bolt action rifle designs Straight pull rifles in video: Blaser R8 Blaser R93 CISM Heym SR 30 Merkel Helix
It's amazing how much information I get from your channel. I have been learning everything I could about firearms for 25 years and I thought I knew a lot. I've read a tremendous amount about guns, and I own many guns, but I still learn so much from your videos. I hope you don't stop anytime soon.
Heym rifles were always one of my favorites for hunting wild boars in Germany. I used to hunt with a SR 20 but the concept of the SR 30 which is still in production is fantastic. One point though is that with the recoiling rounds usually used for wild boar hunting any advantage you get from the straight pull actions is minimal. Especially for fast running pigs it matters more that you have a well fitted stock and lots and lots of practice with your rifle to make that first shot count.
The petals you are referring to, and indeed the whole part, is inspired by a standard machining piece called a collet, specifically an R8 collet. Still a genius move on the part of the designers, as collets have been around for almost a century, since the introduction of the Bridgeport milling machine. Therefore they are proven designs for reliability and accuracy of movement. The term you were searching for is called the "collar" of the collet.
That Blaser system looks to be essentially a modification on the flapper lock system as used on, among others, the Degtyarev machine gun designs. The same basic idea was employed by CETME and later HK in their roller lock designs. My guess is that these straight pull rifles by Blaser and Heym took that basic concept and made the system radial instead of horizontally opposed. These are really cool designs. It's a shame that more companies don't employ them.
Speaking of German guns, the ball bearing lug design on the Heym, is similar to the HK41/G3/91 or their sporter versions 770 etc. all with semi-auto bolts. The HK design is "old school" now but genius...solid, but in the instance of Heym, the lock up is bolt handle actuated instead of cartridge pressure. Thanks for sharing about these amazing and beautiful machines!
Excellent mechanical understanding and comparison. The 770 could have been fully locked as well - if it wasn't a semi. Thanks for spotting and writing.
@@UnitedStatesOfGuns The matching locking recesses of the ball bearings are six individual spheric holes or a single ring in the receiver? Thanks from Brazil
Hi there, actually the Heym isn't discontinued. I've ordered one which will be individualized for me. I've bought the SR 30 PRECISION. It's the only rifle that comes with a hit warranty! Heym guarranties that all rounds of a five series at 100 meters will hit the target within 20 mm - with precise ammunition. Now that's unique, isn't it ?
Hi Dieter! Fantastic - thank you. The SR30 is extraordinary and an engineering tour de force. Please send me a picture of your rifle when it arrives and I'll get it on my channel somehow. I still have my SR30 .270 - I should buy another. Merry Christmas!!! Frohe weihnachten.... I'm guessing.
USOG Hello once again. I've actually, finally, after 6 month waiting time (!!) get my Heym rifle. It's amazing. I don't know how to contact you to send some pictures, of course if you want. Cheers
I'm currently looking at a SR30 as well (in 8x57IS), what I found especially pleasing about the Heym is that it's affordable (I'm Dutch after all)... Around 2,000 euros depending on which options you select in their configurator. That's a bargain.
The Heym SR30 is still very much in production. I have one in .308, fantastic rifle (like the SR21) They are extremely well made and built by hand (the bolt is CNC machined)
Great Video! Just ordered an R8 chambered in 30-06 with a synthetic stock. My first gun was one of the first Mauser 66 (7x64) and I still love it. Greetings from Germany
Mike, those are much like what we call in aviation, “expandable pins”. Which have been used in many forms to lock in and attach things from gearbox mounts to helicopter rotor blades and I’m sure in many other forms, although this a different orientation and application of a similar theory of course.
This guy has literally every gun ever in at least 1-2 examples, always ready to not only tell us about them in one of the most knowledgeable ways on youtube, but he also literally has them to demonstrate!! How does this channel not have at least 1M subs by now?
Thank you for the kind words. I truly appreciate your support. I don't know why my channel is not so popular. I guess I'm not entertaining. I don't mind. All the best.
I love that Merkel, looks like I going to have to do some heavy research and find one, thank you for this amazing video, it was so informative and you presented it so brilliantly, again, thank you, thank you, thank you.
I have a merkel helix and i love iti, best gun ever. 9.3x62 accurate, and it handles better then any other gun, as soon as you raise it you are dead on
The "petals" on the Blaser are what are known as collets in English-speaking machine terminology. In this specific instance, they are acting as an internal collet since they spread outward to grasp the interior of another part instead of clamping inward to grasp the exterior.
Collets is actually a French word (actually collettes) transliterated as tabs so petals could be an actual translation. Similar to the French sabot meaning shoe.
I forgot to mention that I'm trying to get a Strasser RS14 www.hms-strasser.com/en/rs14-standard.htm and the Lynx straight pull will be interesting to examine lynxrifles.fi/ The Lynx reminds me of a Browning T - Bolt but I'm probably way off.
The Strasser is a very smooth action and has the detachable magazine. The scope mount is also very elegant and is very close to the blaser in terms of quality. However you need to get your hands on a Chapuis Rols to compare ;)
@@UnitedStatesOfGuns The matching locking recesses in the Heym SR30 are six individual spheric holes or a single ring? i allways want to Know thanks from Brazil
The ball bearing locking mechanism is a logical extrapolation of the old CETME delayed roller locking system. Maral is a large central asian deer; wapiti plus in size. There is another popular straight pull rifle made in Cologne (Köln), called the Steel Action, which has been around for about 3 years.
Very interesting. When I first saw straight pull rifle actions I thought of the Swiss K31. I had no idea there were these fascinating, ingenious commercial rifles. Thank you!
I have been running a Ruger M77 for forty plus years. What’s important to me is it always does what it’s supposed to do no matter what happens to it. The speed part comes with practise and it becomes instinctive. I never could remember getting the safety off or running the bolt everything just happens lol🇨🇦🤠
love how you said the Merkel could be a pump. I LOVE pumps. There are so few made now. And would love to see more. PS. My favorite pump is a IMI Timberwolf in 357.
I don't know if I'd say it was my favourite. I do love my Winchester M-62. And have an affinity for the Savage 170, Remington 760 and 7600, and the Colt Lightning. I was never crazy about the Browning BPR though. But that IMI Timberwolf .357 mag is as tough as nails , slick as snot and with that heavy barell is dead on accurate. With a little Aimpoint red dot on top it is super fast to handle and sight. The trigger and fire control group are 100% Remington 870, 760, 7600, 1100. Completely functional and proven. The adjustable butt stock is a great idea that works well. If I had to find a detractor I would most adamantly have to say it was the integral top rail. Of the Picitinny rail style but milled as part of the receiver it fails as having tolerances that fit Weaver style rings correctly.There is way to much slop between the milled cuts to properly accept rings with any precision. In every mounting instance and combination they have had to be shimmed. If the rifle was not so sought after, and holding such a premium I would mill off the rail and drill and tap for conventional rings and bases. And probably recess crown the muzzle. But I agree, it is a GREAT rifle !!!
@@UnitedStatesOfGuns Hey Buddy, I just came across your post. If you don't already know, this is how the IMI Timberwolf locks up. If you are familiar with firearms of the Remington 870 family you will see that the entire fire control package is the same for the Timberwolf. As for lockup, the bolt has a milled cut up thru it's center for a freely moving up and down locking block, the bolt and block sit on the bolt carrier which is connected to action rails/arms that go to the forward pump/grip. When pumped, the bolt and bolt carrier move forward or rearward and slide across one another. A pad on the bolt carrier raises or lowers the bolts locking block as they slide across one another. This allows the locking block to engage the cut in the receiver roof for positive lock up or drop down to cycle the action. If you are at all familiar withe the Remington 870 family you will see that this is identical in design and function. Again, I appreciate and enjoy what you do. Bob
Most long guns could be converted to pumps, and many have to avoid legal restrictions. There is an AR- 15 clone sold that is a pump. But semi autos are the easiest to adapt and convert to pumps. Bolt actions can readily be done, however overcoming the mechanical advantage the cramming surfaces the bolt handle has is an issue with a pump. John Browning converted a lever gun to semiautomatic, and Bill Ruger converted a Savage 99 to semiautomatic. So it can be done, but is easiest for semiautomatics to be made into pumps. I would have to say that trying to convert an O/U or S/S shotgun to a pump would be an exercise in futility and one he'll of an engineering challenge !!! But there is ALWAYS some gunsmith willing to try.... just not me !
Magnificent rifles. The only rifle I have in terms of straight pull is a Swiss K11. Not quite as refined as your rifles, but it is an excellent rifle in terms of surplus. It also introduced me to the concept of straight pull bolts. I hope to add more to my collection. Thank you for the info!
Nice review. The flaring lock system is very strong as the ballistic forces are distributed throughout the lock surface within the barrel, and not as rotating lock where the forces are distributed on 2 or 3 points within the locking mechanism.
Thank you and I agree - the R8 and R93 are amazing and absolutely strong. I just ordered a another barrel for my R8 - I find myself liking the R8 more and more.
Another excellent and informative video. Thank you very much. I appreciate the time and thought that you must put into your videos, and hope that you 'keep them coming'.
Yes indeed! Those are classics. I hope I find a 96 soon - I remember the ads - "Rifle for the next century" or something - and I think there were a lot of locking lugs. I have the K31 and the Ross - both fine although the K31 is the better design.
Hello - your K31 is excellent - as you already know. If you do buy the Blaser - you won't be poorer - you'll have a Blaser worth more than the money you exchanged it for - which is paper at best and in and of itself, useless, and can't shoot. : )
Mauser, in the late 1990's made a M96 which is a straight pull action with 16 locking lugs divided into two rows of 8 lugs, thus the head of the bolt need only rotate a small amount compared to most normal rotating bolts or straight pull rotating bolts such as the Steyr.
Hi CharlesinGA, I have been looking for one for a long time. The bolt handle is far forward - which is always interesting to me. Thanks for mentioning.
The BLASER uses a collet to lock up. I bought two R93 rifles back in the late 90's (a 338 LAPUA and a 308WIN). The two are one of the most accurate rifles I own.
I love your videos! The rifles are what one would expect from companies taking pride in every aspect of the finished product. I have subscribed there is nowhere on TH-cam to visit to have a collector handle and demonstrate as you do. Thank you.
I have always wondered how that action locked up, great close up view of the lug pedals in action... Some years back Colt came out with the Colt Sauer bolt action which had 3 large pedals that locked into the action, it's one of the slickest actions i have ever handled ... Oh around 1980's to early 1990's Colt brought that action out.... I have not seen one for years now where i live and shoot..
Colt just marketed the rifle in America. That rifle is pure German. Sauer designed it and sold it as a Sauer product; the model 90. Of note, the Colt Sauer rifles all have glossy stocks like Weatherby rifles. The Sauer model 90 is mostly found with an oil finished stock. The Sauer model 90 was discontinued in 2006 or so, but you can find them on Gun Broker and Guns America.
I know that this specific video was about centrefire straight pull rifles, but, with specific regard to the Heym and its ball locking, I feel that I have to refer you to the wonderful Anschutz 22LR rifles built with the Fortner action. Superb is the only single word description to use.
Hi Aye - Great point - somewhere on the channel is a review of my Fortner - also Savage has just introduced a new straight pull center fire using the same ball bearing locking system.
What is missing about the Blaser Radialbungverschluss: real 360 degreee locking and not in a collar but directly in the barrel so maximum possible accuracy also retaining point of impact when shot hot (this might be something worth paying for - it sure cost more to manufacture). The R93is said had issues with magnum cardridges overpressure so they redesigned the locking collar. The Trigger under the magazine is not only a safety measure but it is somehow overlooked it has a teleskoping bolt like a Mauser 66 since the trigger is under the magazine and the bolt has not to be guided by the system when behind the magazine the overall length of the rifle is reduced by the length of the magazine. The helix can lock up with dirt or bad rounds since the machanism increases the movement of the bolt but at the same ratio reduces the force applied heard from owners having problems with cheap practice ammo - a pump action is a great idea, no legal issues but German hunters are really stuck in their traditions.
Good comments Ragner! The R93 has a more sloped locking collar and the R8 has a larger and sharper shoulder. I think they wanted to be sure that the mechanism would open when the collar was allowed to collapse to its original size by moving the bolt handle backwards on the R93. So they made the locking edges more rounded. The R8 is more certainly locked and since it is a larger bolt overall - they can use a more severe lockiing ledge. I like the design of the Blasers - the lock is more or less a circle of flat springs - quite clever.
You talked about straight pulls and didn't mention the K 31?! 😱😱😃 The Browning is a really interesting idea that I'm surprised no one else has tried. Great solution to places that restrict semi autos. I don't know if it applies, but the Winchester sxp pump shotgun uses a rotary bolt, so that the pump travels much less to achieve the same effect. It's a shotgun, not a rifle, but it does what you were talking about. Thanks for the vid. A couple beauties there
USOG Yes, I could see you were. No worries. I was just slightly surprise you did t throw one in, just for the heck of it, but you were obviously showing high end sporting guns.
@@UnitedStatesOfGuns The matching locking recesses in the Heym are six individual spheric holes or a single ring machined in the receiver? Thanks from Brazil
In most European countries including my own you are limited in the number of rifles that you are allowed to have but not to the number of barrels. That means that interchangeable barrels is poupelar. I am sorry to say that in Sweden we have had a number of accidents with Blaser R93 because that the bolt haven't looked.
You should get a Steel Action from Germany. It is out since 2017-2018 and will become a very popular rifle in the next years or has become popular already in Germany.
The locking system component you didn't know the name of, is called a "collet locking system". It's similar in concept to roller locking or flapper locking.
Thanks Tony, Since that video a few more straight pulls have appeared - quite interesting mechanisms. I'm still waiting for a Stahl and others. All the best!
I just wanted to mention something to you, there's a movie called Predators. There's a character in that movie who uses the R93 target that you have. They painted it black but I always remember that because when I saw it in the movie I didn't know what it was and then you did this video and I always thought that was so cool that I got to find out what that gun was because prior to that I actually thought they designed it for the movie from scratch... funny!!
Thank you! I just came across your video. I wasn't aware of the Browning. I think I'll keep my eyes open for a used one. I still intend to get a Merkel in 308 and 243.
Hey Texas! Gotta love Texas. Hope you can get a Merkel - such a slick rig - ideal for fast hog shooting. All the best to you in the Lone Star! God Bless.
Absolutely brilliantly awesome rifles Blaser's are. Merkel I own a shotgun but unfortunately not a bolt action center fire. My favorite rifle to this day may shock you but it's my Husqvarna.
I dont think it is illegal in Europe to have pump action rifles, they are just considered uncouth and for the most part impractical. There are (mainly) two kinds of shooting here in germany, the one where you sit and wait or maybe walk around a bit, and where you are likely to shoot distances of 100m+. In that situation you want to rest your gun on a ledge or branch for better aim, which makes reloading from the stock cumbersome and not fast at all. The other type is driven shooting, and while reloading is a little faster with a pump action, I find that I take longer to be on target again because by pumping I lose my aim (at a running group of hogs, for example) , which I don't if I use a straight pull action, or at least not as much. I think that is why they have never really caught on in Europe, or at least, germany.
Re: the locking mechanism of the Blaser Bolt, I am familiar with electrical terms and those fingers are similar to what is mounted to the contact points of medium and high voltage circuit breakers. In that field they are referred to as rosettes the gripping area is aided by coil springs wrapping the neck of each contact point very similar to what you are displaying there. I was recently attracted to the Merkel . I currently am interested in the Kreighoff pump called the Semprio did you do a video on that model by any chance?
Hello - That's interesting about the circuit breakers! Yes - we had a Semprio - quite and amazing system. The video is somewhere on the channel. The Semprio is hard to find these days - I wonder how many they are building and selling. Cheers.
I own a small collection that is mostly out of production. I have an SHR 970, Sigg with two barrels currently wearing the 2506 and I have the 3006. I have a savage 99 and 308 with the brass internals it’s currently wearing your favorite iron sights not the original. It has the front site but the rear has been replaced with a red field micrometer Hunter peep intact very good condition. I had it reloaded and colored FN 300 supreme in 270 it shoots Walmart ammo touching holes at 100 yards I haven’t taken it to 200 yard range yet that is scoped. I have a savage 10 ML two muzzleloader, which was the one that was made to shoot smokeless powder it’s very accurate, I feel it shoots better with nose bullets than it does with plastic pointed bullets. And I have one rare pump the browning BP it’s not made anymore but it has a unique cantilevering pump action. Maybe if you have one of those you can do a video on that And I have a Remington 7600 which actually gave me a lot of problems when I first bought it but I since had them all resolved it’s currently wearing avoid stock that I bought from Cabela’s to replace the original synthetic stock. Of my disappointments in the 7600 model is, it is front they replace the center slide tube with two sliding rails but it’s still front heavy and I have a car with the 18 1/2 inch barrel. It is a love-hate relationship because I really would like to get rid of it however, it just keeps shooting straight, I can’t stand it! I am looking forward to getting one of those semipros. I also want one of those Helixes.
93 is the year when the model came out. R08 came out in 2008. This is a common way to name riffles in Europe. The SSG 77 from Steyr was released in 1977. SSG means ScharfSchützenGewehr meaning SniperRiffle. R 08 stands for Repetiergewehr released in 2008.
Thanks for mentioning that; some viewers sent links and the pictures are quite dramatic. Sadly, each year many rifles from various manufacturers fail for a variety of reasons.
I actually came to this video trying to learn about the actions because I'd read in so many places that R93's were somewhat... "famous" I suppose you'd say... for failing and placing the bolt of the weapon squarely into the eye socket of the weapon's user causing horrific injury. Seeing how the action works now, I can't say that I'm surprised. The expansion of the "petals" as USOG calls them is a similar fashion with how automotive seal pullers are used to extract rubber seals, bushings, or bearings from various car parts. They insert into the orifice of the seal, and are expanded out with something that typically screws in or out causing the arms to open up behind the thing you're taking out, and when they're seated in place, you can pull on the tool and it will pull on whatever it is you're taking out. Common cause for those to fail are either the arms wear out, or the surface which they're seating against is damaged or worn. Either way the failure is the same: The tool fails to pull out what it is you're pulling on and instead the tool comes straight out with all the force being exerted on it, causing the technician to either fall straight on his backside, or launch it back in the direction in which he was pulling. This, I suspect, is the same cause of failure for this design of bolt.
From what ive seen, there are 5-6 confirmed cases of the bolt getting separated from the barrels and hurting the shooter when it comes to the R93 and those are all earlier models and that with a catastrophic case failure(and most of those by extremely hot handloads), so about 5-6 out of 250k+ rifles . The R8 has zero incidents of the same kind(no bolt separation), and has been pressure tested to the extreme(14900 BAR by the german DEVA). So i would say the R8 is one of the most safest guns on the market.
Hi, love your videos. The content and variety of rifles from around the world are incredible. I appreciate your sincerity and humbleness. Have you acquired the Browning Maral? If so how would you rate the Browning Maral in the straight-pull bolt action category? I would love to get my hands on a Maral mainly because I'm a big fan of John Moses Browning. When I graduated from college in the early 80s and could afford a good shotgun I bought a Citori Lighting and have been a loyal Browning customer since. I have seen a couple of Aceras in great condition and reasonably priced but I agree on the length or stretch to manipulate the bolt is too long.
I was hoping to see a Swiss Hammerli rifle in this list. They are more of a modified Schmidt Rubin action. These are all exceptional as well though truly wonderful and interesting designs!
Ahhhhhh....Hammerli - such superb firearms, but then, is there anything from Switzerland that is not superb? Anyway, sorry I don't have a single Hammerli in my vault. I used to - but friends come and have to have them - and then they are gone. One of these days a Hammerli will appear and I'll be sure to make a video. Thanks for the reminder.
USOG Yes sir, thank you for the videos, and for the reply! I never knew how superb a rifle could be until I got to hold a Swiss rifle. Fell in love instantly. Yours are obviously fabulous too, and way above my pay grade. Straight pulls are probably my favorite after slide or pump action rifles, but the straight pulls are probably more rugged and practical.
Hey USOG, thanks for the wonderful video. Im in the market for a straight pull system and the Merkel Helix caught my eye, check out the "speedster" version. Love the design of the stock, comes in black, green and orange. I prefer the green one, havent tested it yet tho.
On civil engineering we protend steel of armed concret with an inverse mechanism than Blaser rifles uses. It should be where the idea came from. It is an quite old method of strenthen armed concret putting pre tention on steel. The locking pieces that grab the steel bars has the same principle in the inverse way. Locking bushes used to fix bolts to concret has the same principle of expansion of petals. There are a lot of uses of this principle. Nice to see an well suitable for guns.
Very interesting Luis - thank you for informing us. I had no idea. Many people have written me and note that the Blaser R8 and R93 are their favorite rifles. I have both and find them accurate and reliable; although they both involve a lot of plastic. I don't notice much plastic in civil engineering steel bars and locking pieces yet. : ) Thank you once again and I send the best of health.
The Krieghoff Semprio is also brilliant. But i guess it wasnt included because strictly speaking its not a straight pull. Its effectively a pump action but Krieghoff absolutely hates people saying that and they insist its something completely differend they call a inline repeater.
I don't see how some of them could have a strong primary extraction of stubborn cases using a simple straight pull action. I'd also be worried about durability if you rely on a couple or more ball bearings but then if HK can make semi-auto's with only 2 rollers to delay the opening, I suppose a few ball bearings could do it. I think my favorite would be the Helix. If they are willing to stand up to those huge boars with them they must be reliable.
Useful and interesting as always thank you, I've recently tumbled with an Steyr M95 8x56R in Stutzen variation, beatiful and quick gun and almost seems is at the gun shop waiting for me to bring it home. But I'm worried about the locking mechanism, any insights about it?. Thanks again!
Really wish straight pull bolt guns were more popular in the US. The only one I’ve ever seen in person was a Steyr scout in 22lr. I actually shot today and only took 22lr and 6.5mm bolt guns. Nothing like shooting a bolt gun. Really would like to hear your take on The Fix, by Q.
Beautiful stock on the Browning Acera did you restock it all the Acer's I've seen had plane looking wood always wanted one I kept waiting on something besides a .300 or 30-06 then they discontinued. Nothing against those two calibers I just have quite a few already. Love your channel, do you come to Dallas Safari Show.
My Swiss Model 1896/11 sporter is one of the most accurate rifles I have owned. Best group for me was .256 at 100 yards. Don't forget those cheap and common rifles as among the great ones. It was the Swiss, not the Germans, who first adopted the straight pull rifle.
The Swiss K31 is also a very Interresting straight pull riffle. I have to say the Browning "Marral"? with its automatic return locking system is calling me... 🖖🏻🇫🇷😎🇫🇷😇🇫🇷😎 (I'm a Browning owner)...
Please Answer me , the matching locking recesses in the Heym SR30 are six individual spheric holes or a single ring machined in the receiver? Thanks from Brazil
May I ask, these actions all seem to be very noisy, does anyone have any experience with them as a stalking rifle when a quiet closure of the bolt is needed?
Good question - the R8 and R93 can be closed almost silently as the movement of the bolt only expands the collet. The others can still be pretty quiet if the final locking motion is done slowly.
I really want one of those Heym sr30 rifles. I've never seen one before. According to the USA Heym website, they currently only have it in .308 Winchester, 7mm Rem. Mag, and .300 Win Mag which is pretty disappointing to say the least. Not that those aren't fantastic calibers, but I'd like one in something like a 30-06, .270 Winchester, or even 35 Whelen.
In Germany we can get them in various calibers. I don´t know if there is any possibility to order it in Germany and have it shipped? I can only tell you, that in Germany we can either order them online, configurated how we like it or we can even visit the factory, have some sort of workshop tour and afterwards configure them on-site. here is the german website where you can see all calibers: heym-fabrik.de/?product=sr-30-allround-geradezug-repetierer
It's amazing how much information I get from your channel. I have been learning everything I could about firearms for 25 years and I thought I knew a lot. I've read a tremendous amount about guns, and I own many guns, but I still learn so much from your videos. I hope you don't stop anytime soon.

Blaser, Mauser, Sauer, Merkel and Steyr are definitely great companies with amazing Rifle’s ⚡️
Have 2 schimtRubens. One is a Comercial/ sporter ,both on 1911 actions . Excellent
I finally know what the straight pull attachment in battlefield does. Thank you
That Blaser system looks to be essentially a modification on the flapper lock system as used on, among others, the Degtyarev machine gun designs. The same basic idea was employed by CETME and later HK in their roller lock designs. My guess is that these straight pull rifles by Blaser and Heym took that basic concept and made the system radial instead of horizontally opposed. These are really cool designs. It's a shame that more companies don't employ them.
This is brilliant! Thank you for introducing me (and others) to fantastic guns. Love it.
Thank you! I'll keep going until I run out of guns.....so that's not going to happen.
Speaking of German guns, the ball bearing lug design on the Heym, is similar to the HK41/G3/91 or their sporter versions 770 etc. all with semi-auto bolts. The HK design is "old school" now but genius...solid, but in the instance of Heym, the lock up is bolt handle actuated instead of cartridge pressure. Thanks for sharing about these amazing and beautiful machines!
Excellent mechanical understanding and comparison. The 770 could have been fully locked as well - if it wasn't a semi. Thanks for spotting and writing.

Hi Dieter! Fantastic - thank you. The SR30 is extraordinary and an engineering tour de force. Please send me a picture of your rifle when it arrives and I'll get it on my channel somehow. I still have my SR30 .270 - I should buy another. Merry Christmas!!! Frohe weihnachten.... I'm guessing.
UnitedStatesOfGuns same to you! You are guessing well😁. Mine will be .308 Win
USOG Hello once again. I've actually, finally, after 6 month waiting time (!!) get my Heym rifle. It's amazing. I don't know how to contact you to send some pictures, of course if you want. Cheers
I'm currently looking at a SR30 as well (in 8x57IS), what I found especially pleasing about the Heym is that it's affordable (I'm Dutch after all)... Around 2,000 euros depending on which options you select in their configurator. That's a bargain.
dieter toma Try study Schultz & Larsen if you are interested in superb marksmanship
You are a true gentleman ! Thank you and God Bless!
The Heym SR30 is still very much in production. I have one in .308, fantastic rifle (like the SR21) They are extremely well made and built by hand (the bolt is CNC machined)
Thanks for the correction Mark. I'm glad they are still making them - so unique and excellent.
The matching locking recesses are 6 spheric holes or a single ring in the receiver?
Your appreciation for different means of accomplishing the same mechanical task is infectious. Thanks!
Thank you. So interesting.
Great Video! Just ordered an R8 chambered in 30-06 with a synthetic stock. My first gun was one of the first Mauser 66 (7x64) and I still love it. Greetings from Germany
Fantastic! Your first rifle is really something! And now you have a new classic. Thanks for writing.
The Blaser system called Radialbundverschluss (German)
Thanks Lars!
More like radial locking lugs.
Mike, those are much like what we call in aviation, “expandable pins”. Which have been used in many forms to lock in and attach things from gearbox mounts to helicopter rotor blades and I’m sure in many other forms, although this a different orientation and application of a similar theory of course.
This guy has literally every gun ever in at least 1-2 examples, always ready to not only tell us about them in one of the most knowledgeable ways on youtube, but he also literally has them to demonstrate!! How does this channel not have at least 1M subs by now?
Thank you for the kind words. I truly appreciate your support. I don't know why my channel is not so popular. I guess I'm not entertaining. I don't mind. All the best.
I love that Merkel, looks like I going to have to do some heavy research and find one, thank you for this amazing video, it was so informative and you presented it so brilliantly, again, thank you, thank you, thank you.
I have a merkel helix and i love iti, best gun ever. 9.3x62 accurate, and it handles better then any other gun, as soon as you raise it you are dead on
Amazing analysis. I’ve been searching for a straight bolt design to apply to a slide action. I’m glad someone is looking for the same.
I hope they adapt that Helix design - so quick and elegant. Thanks for writing.
USOG You have an amazing channel, and I hope more people subscribe by the tens.of thousands because you deserve more views.
The "petals" on the Blaser are what are known as collets in English-speaking machine terminology. In this specific instance, they are acting as an internal collet since they spread outward to grasp the interior of another part instead of clamping inward to grasp the exterior.
Collets is actually a French word (actually collettes) transliterated as tabs so petals could be an actual translation. Similar to the French sabot meaning shoe.
That was exactly what I was going to post.
Yes, these are more properly described as an internal collet.
There are many gun channels, but to me yours is the best and most informative with an encyclopedia worth of knowledge.
Great video once again.
I am humbled by your kind words. Thank you Thomas.
I forgot to mention that I'm trying to get a Strasser RS14 www.hms-strasser.com/en/rs14-standard.htm and the Lynx straight pull will be interesting to examine
lynxrifles.fi/
The Lynx reminds me of a Browning T - Bolt but I'm probably way off.
I'm really looking forward to hearing your review of the Lynx. Thanks for making these great videos.
The Strasser is a very smooth action and has the detachable magazine. The scope mount is also very elegant and is very close to the blaser in terms of quality. However you need to get your hands on a Chapuis Rols to compare ;)
Thank you for what you do.
really the best video about modern straight pull action rifles that i see in You Tube, 21 minutes of valious information
Thank you Percy!
That Heym is next level.
So true funcounting - a gem.
@@UnitedStatesOfGuns The matching locking recesses in the Heym SR30 are six individual spheric holes or a single ring? i allways want to Know thanks from Brazil
The pedals make an assembly commonly referred to as a "collet" pronounced Call-it
The ball bearing locking mechanism is a logical extrapolation of the old CETME delayed roller locking system. Maral is a large central asian deer; wapiti plus in size. There is another popular straight pull rifle made in Cologne (Köln), called the Steel Action, which has been around for about 3 years.
There is also the Lynx from finland which is almost a heym sr30 but with steelbars instead of ballbearings.
Thank you for showing these bolt action rifles. In Australia where semi-auto rifles are very difficult to get, these rifles would offer alternatives.
Hello Zia - good point; as quick as a bolt action can get - these straight pulls are something.
Very interesting. When I first saw straight pull rifle actions I thought of the Swiss K31. I had no idea there were these fascinating, ingenious commercial rifles. Thank you!
So interesting for me Rich - I keep going back to them.
Now you are going to have to review the new Savage Impulse rifle. Hope to see you do that soon! I'm very intrigued by that rifle.
Same here. Only thing is that it's unfortunate they made it so damn ugly. Of course, this is typical of Savage...
Thank you for making this video it is fantastic! I have always found these push pull actions fascinating. Have a nice day.
Thanks Avery!
I have been running a Ruger M77 for forty plus years. What’s important to me is it always does what it’s supposed to do no matter what happens to it. The speed part comes with practise and it becomes instinctive. I never could remember getting the safety off or running the bolt everything just happens lol🇨🇦🤠
love how you said the Merkel could be a pump. I LOVE pumps. There are so few made now. And would love to see more. PS. My favorite pump is a IMI Timberwolf in 357.
I missed that one! I tried to buy a Timberwolf at an auction - no success. How does it lock?
I don't know if I'd say it was my favourite. I do love my Winchester M-62. And have an affinity for the Savage 170, Remington 760 and 7600, and the Colt Lightning. I was never crazy about the Browning BPR though. But that IMI Timberwolf .357 mag is as tough as nails , slick as snot and with that heavy barell is dead on accurate. With a little Aimpoint red dot on top it is super fast to handle and sight. The trigger and fire control group are 100% Remington 870, 760, 7600, 1100. Completely functional and proven. The adjustable butt stock is a great idea that works well. If I had to find a detractor I would most adamantly have to say it was the integral top rail. Of the Picitinny rail style but milled as part of the receiver it fails as having tolerances that fit Weaver style rings correctly.There is way to much slop between the milled cuts to properly accept rings with any precision. In every mounting instance and combination they have had to be shimmed. If the rifle was not so sought after, and holding such a premium I would mill off the rail and drill and tap for conventional rings and bases. And probably recess crown the muzzle. But I agree, it is a GREAT rifle !!!
@@UnitedStatesOfGuns Hey Buddy, I just came across your post. If you don't already know, this is how the IMI Timberwolf locks up. If you are familiar with firearms of the Remington 870 family you will see that the entire fire control package is the same for the Timberwolf. As for lockup, the bolt has a milled cut up thru it's center for a freely moving up and down locking block, the bolt and block sit on the bolt carrier which is connected to action rails/arms that go to the forward pump/grip. When pumped, the bolt and bolt carrier move forward or rearward and slide across one another. A pad on the bolt carrier raises or lowers the bolts locking block as they slide across one another. This allows the locking block to engage the cut in the receiver roof for positive lock up or drop down to cycle the action. If you are at all familiar withe the Remington 870 family you will see that this is identical in design and function. Again, I appreciate and enjoy what you do. Bob
Most long guns could be converted to pumps, and many have to avoid legal restrictions. There is an AR- 15 clone sold that is a pump. But semi autos are the easiest to adapt and convert to pumps. Bolt actions can readily be done, however overcoming the mechanical advantage the cramming surfaces the bolt handle has is an issue with a pump. John Browning converted a lever gun to semiautomatic, and Bill Ruger converted a Savage 99 to semiautomatic. So it can be done, but is easiest for semiautomatics to be made into pumps. I would have to say that trying to convert an O/U or S/S shotgun to a pump would be an exercise in futility and one he'll of an engineering challenge !!! But there is ALWAYS some gunsmith willing to try.... just not me !
I really appreciate your demeanor in all your videos
Thanks Ventris.
Magnificent rifles. The only rifle I have in terms of straight pull is a Swiss K11. Not quite as refined as your rifles, but it is an excellent rifle in terms of surplus. It also introduced me to the concept of straight pull bolts. I hope to add more to my collection. Thank you for the info!
Hi, I just found your channel and I love the way you talk about these guns. I've never owned a gun but your knowledge really makes me want to learn.
Rößler and Lynx also make excellent straight-pull rifles.
I'm hoping to get a Lynx - fantastic mechanism.
Nice review. The flaring lock system is very strong as the ballistic forces are distributed throughout the lock surface within the barrel, and not as rotating lock where the forces are distributed on 2 or 3 points within the locking mechanism.
Thank you and I agree - the R8 and R93 are amazing and absolutely strong. I just ordered a another barrel for my R8 - I find myself liking the R8 more and more.
Another excellent and informative video. Thank you very much. I appreciate the time and thought that you must put into your videos, and hope that you 'keep them coming'.
Will do MG - so interesting for me and I'm learning a lot from so many.
The new steel-action HS looks interesting.
Awesome video, very informative and well presented, thank you
Thank you John!
Swiss k31. Canada Ross m10. Mauser m96. Those are also pretty cool.
Yes indeed! Those are classics. I hope I find a 96 soon - I remember the ads - "Rifle for the next century" or something - and I think there were a lot of locking lugs. I have the K31 and the Ross - both fine although the K31 is the better design.
Cool. Looks like an R8 machine collet (operating in reverse) and actuated by mechanics similarly found in a ball-lok pin.
I still love my K31. lol But the day I can afford one of these, especially the Blaser, I will be a touch poorer.
Hello - your K31 is excellent - as you already know. If you do buy the Blaser - you won't be poorer - you'll have a Blaser worth more than the money you exchanged it for - which is paper at best and in and of itself, useless, and can't shoot. : )
Here in Germany the Blaser locking mechanism is called Radial Collar Lock (Radialbundverschluss).
I like that. Thank you!
Innogun also makes a straight pull, and a pumprifle, and a pumprifle + combination rifle
I'll have to wait until I'm in Europe to examine these - can't find any stateside. Thanks for the heads up.
Thanks for a great demo that locking mechanism is the same as some locks on aircraft doors called click/clacks
I had no idea! Always interesting to find a mechanism from one thing in a totally different application.
Actually, the term, that suits that kind of locking most is collet locking.
Mauser, in the late 1990's made a M96 which is a straight pull action with 16 locking lugs divided into two rows of 8 lugs, thus the head of the bolt need only rotate a small amount compared to most normal rotating bolts or straight pull rotating bolts such as the Steyr.
Hi CharlesinGA, I have been looking for one for a long time. The bolt handle is far forward - which is always interesting to me. Thanks for mentioning.
I liked the Merkel and the Heym(am sure it's pricey) but your idea of a pump action Merkel would rock. IMO
They sure are pricey Boris. BTW - the Semprio is such a remarkable design - I'm more and more impressed.
USOG i saw the semprio review today and replied. You sir have awesome collection. I have a couple and a couple i wish i hadn't sold
I seem to regret every gun I've sold. Thanks for the good words. : )
USOG there where a couple of duds i was glad to sell, i regret to say
Heym is actually far cheaper than the Merkel and blaser
“You have to trust that the system will work”
D:
“-Which it does”
:D
The BLASER uses a collet to lock up. I bought two R93 rifles back in the late 90's (a 338 LAPUA and a 308WIN). The two are one of the most accurate rifles I own.
Just amazing.. you are an excellent professor.. greetings from Oman.
I love your videos! The rifles are what one would expect from companies taking pride in every aspect of the finished product. I have subscribed there is nowhere on TH-cam to visit to have a collector handle and demonstrate as you do. Thank you.
Brilliant designs all of them.
They really are. How hard they worked to design and build these mechanisms. Amazing.
In germany we appreciate Heym Rifles very much 😉
They're so fine - hard to believe such quality is still available at a reasonable price.
What state are you in?
I’ve been looking for a Merkel helix for some time also.
A merkel pump would be amazing
I have always wondered how that action locked up, great close up view of the lug pedals in action... Some years back Colt came out with the Colt Sauer bolt action which had 3 large pedals that locked into the action, it's one of the slickest actions i have ever handled ... Oh around 1980's to early 1990's Colt brought that action out.... I have not seen one for years now where i live and shoot..
Colt just marketed the rifle in America. That rifle is pure German. Sauer designed it and sold it as a Sauer product; the model 90. Of note, the Colt Sauer rifles all have glossy stocks like Weatherby rifles. The Sauer model 90 is mostly found with an oil finished stock. The Sauer model 90 was discontinued in 2006 or so, but you can find them on Gun Broker and Guns America.
I know that this specific video was about centrefire straight pull rifles, but, with specific regard to the Heym and its ball locking, I feel that I have to refer you to the wonderful Anschutz 22LR rifles built with the Fortner action.
Superb is the only single word description to use.
Hi Aye - Great point - somewhere on the channel is a review of my Fortner - also Savage has just introduced a new straight pull center fire using the same ball bearing locking system.
What is missing about the Blaser Radialbungverschluss: real 360 degreee locking and not in a collar but directly in the barrel so maximum possible accuracy also retaining point of impact when shot hot (this might be something worth paying for - it sure cost more to manufacture). The R93is said had issues with magnum cardridges overpressure so they redesigned the locking collar. The Trigger under the magazine is not only a safety measure but it is somehow overlooked it has a teleskoping bolt like a Mauser 66 since the trigger is under the magazine and the bolt has not to be guided by the system when behind the magazine the overall length of the rifle is reduced by the length of the magazine. The helix can lock up with dirt or bad rounds since the machanism increases the movement of the bolt but at the same ratio reduces the force applied heard from owners having problems with cheap practice ammo - a pump action is a great idea, no legal issues but German hunters are really stuck in their traditions.
Good comments Ragner! The R93 has a more sloped locking collar and the R8 has a larger and sharper shoulder. I think they wanted to be sure that the mechanism would open when the collar was allowed to collapse to its original size by moving the bolt handle backwards on the R93. So they made the locking edges more rounded. The R8 is more certainly locked and since it is a larger bolt overall - they can use a more severe lockiing ledge. I like the design of the Blasers - the lock is more or less a circle of flat springs - quite clever.
The wooden ball knob is a nice little touch.
You talked about straight pulls and didn't mention the K 31?! 😱😱😃
The Browning is a really interesting idea that I'm surprised no one else has tried. Great solution to places that restrict semi autos.
I don't know if it applies, but the Winchester sxp pump shotgun uses a rotary bolt, so that the pump travels much less to achieve the same effect. It's a shotgun, not a rifle, but it does what you were talking about.
Thanks for the vid. A couple beauties there
Great point Jim - sorry. I also forgot the Ross and others. I guess I was thinking of commercial and sort of recent rifles.
USOG Yes, I could see you were. No worries. I was just slightly surprise you did t throw one in, just for the heck of it, but you were obviously showing high end sporting guns.
One thing that has always never made sense to me about straight pull actions is, why don't they just use a Garand action and remove the gas parts?
Thanks again for the great reveiw, really liked the Heym . Might keep an eye out
Hi Andrew - pretty amazing action and engineering. I hope you buy one before they stop making them.
@@UnitedStatesOfGuns The matching locking recesses in the Heym are six individual spheric holes or a single ring machined in the receiver? Thanks from Brazil
Best rifle Lynx from Finland
Hi Kari - you may be right! I've been trying to buy one for years - no luck so far.
In most European countries including my own you are limited in the number of rifles that you are allowed to have but not to the number of barrels.
That means that interchangeable barrels is poupelar.
I am sorry to say that in Sweden we have had a number of accidents with Blaser R93 because that the bolt haven't looked.
You should get a Steel Action from Germany. It is out since 2017-2018 and will become a very popular rifle in the next years or has become popular already in Germany.
The locking system component you didn't know the name of, is called a "collet locking system". It's similar in concept to roller locking or flapper locking.
Thanks Tony, Since that video a few more straight pulls have appeared - quite interesting mechanisms. I'm still waiting for a Stahl and others. All the best!
@@UnitedStatesOfGuns I agree, it's very interesting, and thanks for the great content.
I just wanted to mention something to you, there's a movie called Predators. There's a character in that movie who uses the R93 target that you have. They painted it black but I always remember that because when I saw it in the movie I didn't know what it was and then you did this video and I always thought that was so cool that I got to find out what that gun was because prior to that I actually thought they designed it for the movie from scratch... funny!!
Very cool rifle for sure - I didn't know about the movie use - I'll have a look. Thanks for that!
Thank you! I just came across your video. I wasn't aware of the Browning. I think I'll keep my eyes open for a used one. I still intend to get a Merkel in 308 and 243.
Hey Texas! Gotta love Texas. Hope you can get a Merkel - such a slick rig - ideal for fast hog shooting. All the best to you in the Lone Star! God Bless.
@@UnitedStatesOfGuns Found one but quite fancy. Sent email off to Merkel USA asking if an Alpina was available in 308 with a 243 bbl I hope so!
Absolutely brilliantly awesome rifles Blaser's are. Merkel I own a shotgun but unfortunately not a bolt action center fire. My favorite rifle to this day may shock you but it's my Husqvarna.
Hi Eric - brilliant choice : Husqvarnas are fantastic!
Again you have the best toys...........
I dont think it is illegal in Europe to have pump action rifles, they are just considered uncouth and for the most part impractical. There are (mainly) two kinds of shooting here in germany, the one where you sit and wait or maybe walk around a bit, and where you are likely to shoot distances of 100m+. In that situation you want to rest your gun on a ledge or branch for better aim, which makes reloading from the stock cumbersome and not fast at all. The other type is driven shooting, and while reloading is a little faster with a pump action, I find that I take longer to be on target again because by pumping I lose my aim (at a running group of hogs, for example) , which I don't if I use a straight pull action, or at least not as much. I think that is why they have never really caught on in Europe, or at least, germany.
Re: the locking mechanism of the Blaser Bolt, I am familiar with electrical terms and those fingers are similar to what is mounted to the contact points of medium and high voltage circuit breakers. In that field they are referred to as rosettes the gripping area is aided by coil springs wrapping the neck of each contact point very similar to what you are displaying there. I was recently attracted to the Merkel . I currently am interested in the Kreighoff pump called the Semprio did you do a video on that model by any chance?
Hello - That's interesting about the circuit breakers! Yes - we had a Semprio - quite and amazing system. The video is somewhere on the channel. The Semprio is hard to find these days - I wonder how many they are building and selling. Cheers.
I own a small collection that is mostly out of production. I have an SHR 970, Sigg with two barrels currently wearing the 2506 and I have the 3006. I have a savage 99 and 308 with the brass internals it’s currently wearing your favorite iron sights not the original. It has the front site but the rear has been replaced with a red field micrometer Hunter peep intact very good condition. I had it reloaded and colored FN 300 supreme in 270 it shoots Walmart ammo touching holes at 100 yards I haven’t taken it to 200 yard range yet that is scoped. I have a savage 10 ML two muzzleloader, which was the one that was made to shoot smokeless powder it’s very accurate, I feel it shoots better with nose bullets than it does with plastic pointed bullets. And I have one rare pump the browning BP it’s not made anymore but it has a unique cantilevering pump action. Maybe if you have one of those you can do a video on that And I have a Remington 7600 which actually gave me a lot of problems when I first bought it but I since had them all resolved it’s currently wearing avoid stock that I bought from Cabela’s to replace the original synthetic stock. Of my disappointments in the 7600 model is, it is front they replace the center slide tube with two sliding rails but it’s still front heavy and I have a car with the 18 1/2 inch barrel. It is a love-hate relationship because I really would like to get rid of it however, it just keeps shooting straight, I can’t stand it! I am looking forward to getting one of those semipros. I also want one of those Helixes.
93 is the year when the model came out. R08 came out in 2008. This is a common way to name riffles in Europe. The SSG 77 from Steyr was released in 1977. SSG means ScharfSchützenGewehr meaning SniperRiffle. R 08 stands for Repetiergewehr released in 2008.
Thank you! Makes sense.
Excellent and very instructive video, Thanks Very Much
Thank you! All the best for 2020!
Well, the R93 did blow up..a lot of them!
Thanks for mentioning that; some viewers sent links and the pictures are quite dramatic. Sadly, each year many rifles from various manufacturers fail for a variety of reasons.
Indeed they do, the sad part of the issues with the R93 is the way Blaser has chosen to handle them. The company fails even worse than their product!
I actually came to this video trying to learn about the actions because I'd read in so many places that R93's were somewhat... "famous" I suppose you'd say... for failing and placing the bolt of the weapon squarely into the eye socket of the weapon's user causing horrific injury.
Seeing how the action works now, I can't say that I'm surprised. The expansion of the "petals" as USOG calls them is a similar fashion with how automotive seal pullers are used to extract rubber seals, bushings, or bearings from various car parts. They insert into the orifice of the seal, and are expanded out with something that typically screws in or out causing the arms to open up behind the thing you're taking out, and when they're seated in place, you can pull on the tool and it will pull on whatever it is you're taking out.
Common cause for those to fail are either the arms wear out, or the surface which they're seating against is damaged or worn. Either way the failure is the same: The tool fails to pull out what it is you're pulling on and instead the tool comes straight out with all the force being exerted on it, causing the technician to either fall straight on his backside, or launch it back in the direction in which he was pulling. This, I suspect, is the same cause of failure for this design of bolt.
From what ive seen, there are 5-6 confirmed cases of the bolt getting separated from the barrels and hurting the shooter when it comes to the R93 and those are all earlier models and that with a catastrophic case failure(and most of those by extremely hot handloads), so about 5-6 out of 250k+ rifles . The R8 has zero incidents of the same kind(no bolt separation), and has been pressure tested to the extreme(14900 BAR by the german DEVA). So i would say the R8 is one of the most safest guns on the market.
Hi, love your videos. The content and variety of rifles from around the world are incredible. I appreciate your sincerity and humbleness.
Have you acquired the Browning Maral? If so how would you rate the Browning Maral in the straight-pull bolt action category? I would love to get my hands on a Maral mainly because I'm a big fan of John Moses Browning. When I graduated from college in the early 80s and could afford a good shotgun I bought a Citori Lighting and have been a loyal Browning customer since. I have seen a couple of Aceras in great condition and reasonably priced but I agree on the length or stretch to manipulate the bolt is too long.
Merci beaucoup l'Ami !
You have the best toys.........i am so jealous. thank you for sharing
Thanks Bob - wish I had another lifetime.
I was hoping to see a Swiss Hammerli rifle in this list. They are more of a modified Schmidt Rubin action. These are all exceptional as well though truly wonderful and interesting designs!
Ahhhhhh....Hammerli - such superb firearms, but then, is there anything from Switzerland that is not superb? Anyway, sorry I don't have a single Hammerli in my vault. I used to - but friends come and have to have them - and then they are gone. One of these days a Hammerli will appear and I'll be sure to make a video. Thanks for the reminder.
USOG Yes sir, thank you for the videos, and for the reply! I never knew how superb a rifle could be until I got to hold a Swiss rifle. Fell in love instantly. Yours are obviously fabulous too, and way above my pay grade. Straight pulls are probably my favorite after slide or pump action rifles, but the straight pulls are probably more rugged and practical.
old video i know but i'd really like a look at the physics of the heym. It' so great to see something i haven't seen before so thank a lot :)
Thanks for watching. Those Heyms...so interesting.
Fantastic really beautiful rifles thank you for sharing .cheers .
My privilege.
Hey USOG, thanks for the wonderful video. Im in the market for a straight pull system and the Merkel Helix caught my eye, check out the "speedster" version. Love the design of the stock, comes in black, green and orange. I prefer the green one, havent tested it yet tho.
On civil engineering we protend steel of armed concret with an inverse mechanism than Blaser rifles uses. It should be where the idea came from. It is an quite old method of strenthen armed concret putting pre tention on steel. The locking pieces that grab the steel bars has the same principle in the inverse way. Locking bushes used to fix bolts to concret has the same principle of expansion of petals. There are a lot of uses of this principle. Nice to see an well suitable for guns.
Very interesting Luis - thank you for informing us. I had no idea. Many people have written me and note that the Blaser R8 and R93 are their favorite rifles. I have both and find them accurate and reliable; although they both involve a lot of plastic. I don't notice much plastic in civil engineering steel bars and locking pieces yet. : ) Thank you once again and I send the best of health.
The Krieghoff Semprio is also brilliant. But i guess it wasnt included because strictly speaking its not a straight pull. Its effectively a pump action but Krieghoff absolutely hates people saying that and they insist its something completely differend they call a inline repeater.
I don't see how some of them could have a strong primary extraction of stubborn cases using a simple straight pull action. I'd also be worried about durability if you rely on a couple or more ball bearings but then if HK can make semi-auto's with only 2 rollers to delay the opening, I suppose a few ball bearings could do it. I think my favorite would be the Helix. If they are willing to stand up to those huge boars with them they must be reliable.
I'm not sure where the beginning is with straight pull rifles. Though I've only handled one ONCE, the 1895, 6mm Lee Navy was an interesting firearm.
Useful and interesting as always thank you, I've recently tumbled with an Steyr M95 8x56R in Stutzen variation, beatiful and quick gun and almost seems is at the gun shop waiting for me to bring it home. But I'm worried about the locking mechanism, any insights about it?. Thanks again!
Really wish straight pull bolt guns were more popular in the US. The only one I’ve ever seen in person was a Steyr scout in 22lr. I actually shot today and only took 22lr and 6.5mm bolt guns. Nothing like shooting a bolt gun. Really would like to hear your take on The Fix, by Q.
I hope the straight pulls become more popular as well. I heard someone is putting one into production in the USA soon.
Browning T-bolt is a straight pull rimfire. Not too hard to find.
Beautiful stock on the Browning Acera did you restock it all the Acer's I've seen had plane looking wood always wanted one I kept waiting on something besides a .300 or 30-06 then they discontinued. Nothing against those two calibers I just have quite a few already. Love your channel, do you come to Dallas Safari Show.
I have an Acera in 30-06 I would sell you...
Please try some innogun rifles. They‘re amazing but get less attention than the other brands.
My Swiss Model 1896/11 sporter is one of the most accurate rifles I have owned. Best group for me was .256 at 100 yards. Don't forget those cheap and common rifles as among the great ones. It was the Swiss, not the Germans, who first adopted the straight pull rifle.
Those K31s are something aren't they - amazing.
thanks sir new world for me
The Swiss K31 is also a very Interresting straight pull riffle. I have to say the Browning "Marral"? with its automatic return locking system is calling me...
🖖🏻🇫🇷😎🇫🇷😇🇫🇷😎
(I'm a Browning owner)...
Please Answer me , the matching locking recesses in the Heym SR30 are six individual spheric holes or a single ring machined in the receiver? Thanks from Brazil
May I ask, these actions all seem to be very noisy, does anyone have any experience with them as a stalking rifle when a quiet closure of the bolt is needed?
Good question - the R8 and R93 can be closed almost silently as the movement of the bolt only expands the collet. The others can still be pretty quiet if the final locking motion is done slowly.
USOG thank you.
I love the sr30 but is there a way that i could bet that barrel to a smaller size instead of "26"?
I think they should make a carbine - I'll check in Europe.
USOG okay let me know thanks!
I really want one of those Heym sr30 rifles. I've never seen one before. According to the USA Heym website, they currently only have it in .308 Winchester, 7mm Rem. Mag, and .300 Win Mag which is pretty disappointing to say the least. Not that those aren't fantastic calibers, but I'd like one in something like a 30-06, .270 Winchester, or even 35 Whelen.
In Germany we can get them in various calibers. I don´t know if there is any possibility to order it in Germany and have it shipped? I can only tell you, that in Germany we can either order them online, configurated how we like it or we can even visit the factory, have some sort of workshop tour and afterwards configure them on-site.
here is the german website where you can see all calibers:
heym-fabrik.de/?product=sr-30-allround-geradezug-repetierer
