Tested: Best FX Barrels for JSB Knock-Out .25
ฝัง
- เผยแพร่เมื่อ 6 ก.ย. 2024
- All shots at 100 yards using my FX Impact MK2 @1000fps. This is not a paid advertisement, but the supplies were free. JSB supplied me with the ammo at no cost. FXUSA supplied me with the barrel liners at no cost.
I dont even own a FX and still watch all of these videos all the way though with complete attention. Very interesting!!!
Ted please keep going with all this testing. Im sorry it must be costing you a small fortune but believe me when I say there are thousands of us who watch these tests with great interest, well done to you 👏
Ted, I'm a firm believer in the old way of just trying different projectiles. I've seen too many times where even 2 barrels made side by side will prefer different projectiles. I understand you're trying to formulate a good starting point and outline consistencies. I do believe there is a solid relationship to projectile weight vs twist rate and what's compatible \ effective. I believe once that is close it's a matter of what outside diameter of projectile your particular barrel prefers.
Please, please, please keep sharing your data. Nothing refutes good science!
Please keep bringing us the data Ted. We trust you my friend.
I’m a Daystate man but still watch Ted all the time, can wait for the utube ding, you can’t beat the godfather of air.
Let me answer your first question:
No, I do not own a comb or mirror.
HoldOver Vlog like we didn't know already
It's okay. I don't own scissors, razors, or clippers. :)
Please keep bringing us the data Ted. We trust you my friend.
Have you been testing the .35 impact? If I’m looking for the best possible accuracy, should I get a .30 or .35
Love the videos by the way
Ted it’s during a pandemic brushing your hair is not required
You did shave so you’re not completely lazy😂😂
Ted. I think that I speak for everybody when I say that your time and effort are well spent and we thank you for doing all of this great work.
Thanks Ted, always a pleasure to watch your reviews etc, honesty is defo your strong point over other TH-camrs. Awesome 😁
Oh man, look forward to the .30 Impact against the Maverick!!!!! Wooohoooo!
Ted... your a cool dude! Think Matt should organize a bench rest 100 here in S.A so that we all can meet and compete!
Love getting your insight and expertise for FX guns. Waiting on your work on the Maverick and hoping that will be my next FX purchase. Keep up the great work.
Your time and unselfish knowledge sharing is much appreciated. Please don't burn yourself out. Been airgunning since the late 70s. It's been a rollercoaster ride. But found one thing that is important, keeping life well rounded with family and friends and not get to absorb in my hobbies. Take care.
Thanks for sharing all the testing with us Ted. I have noticed that the 26 gr FX Hybrid slugs make a cleaner hole in my paper targets at 40 yds than the 34 gr Nielson Dimple nose. Hybrids traveling about 950 fps and the Nielson's about 844. Guess I need to buy some Knockouts now? I do know it's a lot cheaper to shoot the Nielson's than the Hybrids.
Always awsome Ted. Vary nice data simple showing of how it takes trial and error.
Man do I miss watching new videos from you Ted. Hope you are doing well sir. We need the Airgun GOAT back!
... you’re great, keep going, among the most informative videos in airgun world ... thanks🇱🇧
Thanks for the info I have both 25 cal superior liner light and heavy this helps out alot thank brotha you are the man thanks for sharing bsafe
Having shot .22 lr no two barrels will shoot exactly the same they may be similar but one will have a sweet spot for certain ammo. Time, trial and error to sort things out but you are giving valid starting points. A variety of weights and diameters in slug packaging maybe a place to start.
U R a natural, man. Love watching your videos.
You may not be wrong with the angle of impact on the paper but it may not be the projectile it may be the target if it’s as windy as you say the target could have blown off of 90 to the angle of impact may not be the slug If you could re-create it on a piece of plywood with a hole cut out so the pellets can pass through then yes it’s the slug I believe the range you shoot at uses a construction fence to hang your targets so there’s room for movement just a thought
Great point!!!
very good point
As for the pitch, maybe a job for the Slow Mo Guys, Dan and Gavin! Ted, thank you for all the work you put into these videos. You’ve helped me issue terror to my regional Starling community.
I Hope your well. Haven't watched a new video from you in a long while. Love your comments and knowledge you share with us and always salivate for more info from you. Again I hope your good as is yours and all is well. We are missing you brotha!
I agree with Pelletgunner the pellet is tumbling at 100 yards, this is why you are getting angled wholes instead of a straight punch. I have seen this shotting .308 on paper targets at long distances with light rounds that do not stabilize correctly.
Ha, I may be one of the few that actually likes the pellet/slug culling process!
I have chased Jeff's Crown and finally got my new MK2 Crown .22 to match his....Ha, probably helped I bought it from him and had him set it up but even then it took time to massage everything to get it there......
My other guns, part of the fun is loading up the range bag and getting outside and trial and error.....That feeling when you finally get that MOA group at 100 and the fiddling with this and that to get there..
I have owned EVERY FX gun produced and would not trade all the options today and that process of seeing what works for the days of chambering a 25.39 in my 500 and knowing that was the best ammo period...
To your point of a formula.....Throw in the towel. Each barrel no matter who makes it via what process will never be 100% equal. Tiny grooves or imperfections will turn an inch group into a two inch group when it comes to the ammo we shoot.
There is a reason why a 175 grain slug out of a big bore is more predictable when shot out of the same brand and make of gun.....Sheer heft absorbs those imperfection better than a 33 grain soft based slug.
Find what works for YOU and enjoy it...For God sakes when you do hit the nail on the head LEAVE it be and just savor it!!
That being said I have found 600mm is better for me with slugs....NO idea why but I am guessing the interaction with the ammo and the barrel makes all the difference and somehow 600mm gives the best results on the barrel imposing its will on the slug (or pellet)...My findings so take with a grain of salt.
Stay well Ted and as always appreciate the detail you put in to each video!
I tend to think they knew who the rifle was going to. My .25 Maverick compact arrived shooting the kings at 745 fps on max. Adjusted the hammer spring a lot to get those and hades to just under 900, now its right. Other reviewers have theirs arrive shooting slugs in the high 900's.
Thanks for doing the dirty work for us, that would sure require a boat load of money for the average man to achieve
The slugs are great in heavy cross wind. I have aplace on the river. The wind howls . You can hear the smack real well.
Although I do not shot out to 75 or 100 yards I still find your videos very informative. The effort you put into your accuracy/testing is amazing Ted, can’t what for the next one.
HOLDOVER LOOKS ALWAYS SO HAPPY WEN HE TALKS ABOUT AIR GUNS ...YOU A KOOL DUDE...LOVE YOUR CHANNEL
Thanks Ted . Your information is so good And a huge help to my shooting . Only one other guy I hang on to every word he speaks is my mate Harry from Australia. Thanks Ted keep it up
Thanks for all the testing! Really helps us. I'm interested to know what caused the target tears as well. Please include that in a video if you find out. Looking forward to a Maverick video from you!! My .25 should arrive tomorrow!
Would like see you take some of these barrel/slug combos out and do real world plinking of pest birds. As always your tenacity is appreciated.
Uneven holes are from unstable projectiles experiencing yaw, from poor or insufficient spin stabilization.
Wrong twist rate will cause this
All the tears in his target where at 12:00. Yaw is a is a projectile starting to wabble and spiral. Ten shot group would have tears going in different directions. I can’t say what is causing it, and yaw certainly would, but every tear was at the same 12:00 position. Maybe see what it does at 90 yards or 110? Quite interesting.
@@KC-dx5pf This can be true, but airguns are incredibly consistent ( .001% velocity variation in a well tuned gun), and the ammunition is more consistent than your average centerfire factory load- they are generally cold-forged/swaged into their final shape and so the weights are generally sub tenth-grain variance. Due to the (very consistent) harmonics of the gun, you can generally see chains of shots with similar patterns, because the projectile is leaving the barrel in precisely the same manner that it did before and may be carrying several different moments as it flies through the air, one of which could have it nose down or nose up for most of the flight.
Id like to see what happens if the FPS were increased.
All I can say is...RESPECT!
I got my eyes on the Maverick. Looking forward to the next video. 👍🇺🇲✌
Mr Ted.... We miss you man..!
Awesome video and info I'm watching your videos alot I had my mk2 25 cal 700mm pp shooting 34 gr varmint knockers at 1025 fps reg at 170 bar but it got boring so now I tune it down to shoot jsb and fx pellets 34 gr heavy jsb mk2 at 890 to 900 fps I turned my my reg down to 80 bar because it has so many ernest Rowe mods to shoot slugs if I put the reg at 110 bar the pellets were flying fast 975 fps but I finally got it at 90 bar and the hammer barely hitting the valve and I change out the light (slugkit) spring with ball to the spring that comes with the gun I had to cus it was wasting air even though the reg was at 90 bar it was still wasting air so I changed spring now it's badass 34 gr fx pellets at 895 av freaking one hole groups at 98 yards and 50 yards one freaking hole wow with the superior heavy liner in it I got the standard liner as well but I Plan on shoot hybrid as well if I want longer range thanks ted you are the man brother thanks for sharing your info
Thanks Ted for your great work!
I do the jsb ko .25 mk1 in my stx high 8s and they perform really well in 50m
I love to try out the mk2 when it arrives
🙏
Ted;
I really appreciate your efforts to sift through the myriad of possibilities to help us find barrels and slugs that might shoot well together. I have one suggestion. Please get new targets with multiple bullseyes. It would clean up the visual display of your testing results. Keep up the good work. Thanks.
hope your doing well ted in this crazy world. miss your videos and i hope your doing well.
I guess I'd better change barrels and dial in the .25's ? The .22 x 500 mm is so much fun though. Merry Christmas Ted. Great video.
Great video Ted. I learned a ton. Think you are right about the ammo coming in at a different angle.
Appreciate the hard work you do to find an accurate combination. I haven’t had much luck with slugs
My money is on your .30 impact! I have worked hard to replicate you and your rifles groups, and have gotten quite good, but no cigar!
I just got my 25 cal Maverick sniper Thursday. I put the Element Titan scope on it (your welcome). Nice scope. . I shot for about 1 hr at UA in Orem UT. It is a 30 yrd range. What is interesting is I had the Crown before I got the Maverick and I would get some fliers but the Maverick right out of the box after UA set it all up shot a lot better groups. Four shots less than .2 CC So what I am saying the advancement in the technology on these rifles is amazing and the things you thought you might be doing wrong bad trigger pull, breathing etc. may not have been the problem. It was the equipment had some variables that the new guns don't have. The purchase was well worth the money.
c
TED!! Ha, any chance you want to move some tins of those MK1 33.95 grain!!
Sold out everywhere and like you, a year or so back discovered the slug A LOVES them and went out and bought 100 tins but down to my last two!
Keep Well,
Dr. Mike Long
The problem with the tears is your bullets are not stabilised enough, I had this with a 243 win in the past, had the same pattern with heavier bullets 100grs, once I dropped down to 85 gr it was shooting like a laser. Basically my twist rate was too slow, don’t know if that’s the case with your barrel. Just started into PCP, not enough experience yet. Nice vid.
Great point and one that regularly plagues the airgun shooter.
My honest opinion is that any variable could cause destabilisation. And it only has to be a small one.
I was shooting QYS domed 2 wks ago at the range with winds of 0-4mph. Groupings we’re awful with tears like Ted is showing.
Last week, the wind was 10-15mph and with exactly the same set-up, I was 10mm groups at the same distance. (Only 30m but I’m in the UK and that’s my ratting distance).
The only variable I can think of to cause the destabilising is the wind.
It seems counterintuitive but the QYS pellets are seeming to perform better with some wind.
More testing required. 👍
Great video with great content . This is where a good high speed camera down range might help . To see the position of the projectiles are as they enter the targets . Keep this s@#t coming . One day we will be able to use all this data .
Thanks Ted. Keep them coming.
Ted, as usual, great vid. Kudos. Wish you be testing the Impact Compact in standard form with slugs/knockouts/hybrid soon.
Love your honest and down to earth videos 🙂
Keep up the good work👍
Another great video Ted. Just got my .30 Cal 700mm and some JSB 44 gr Not sure what barrel i have. So excited ! Keep up the good work !
Thanks a lot ted... the mk1s work really good in my avenger... I want to give the mk2s a try after seeing this🙂🙂
I hope you do 30 cal next that's my caliber
I'm waiting for the JSB .30 slugs to come out (which will soon come out) 😜
As always, exelente works Ted!
Another valuable tutorial mate, great work, keep it up.
new to FX in fact im on back order. .30 Dreamline bottle. ordered the chronny and extra mags/bottles but I will be in way over my head having never had a regulated tune-able gun b4. heyzues that scope is way big must cost as much or more than the gun and add 3 lbs I've Wanted an FX for years because of your videos.
My experience with slugs coming in "tilted", you need to either go up or down in velocity 👍🙂
I was thinking down. I feel FX is trying to get thinks to work in the 900ish range. I definitely try myself with my new Maverick
i agree. they look like they are spiraling in the video to me.
It depends on the liner. Superior heavy…I would say increase speed
Superior….decrease.
Ted, can you put a slo-mo camera at 90 degrees to the poi so you can establish pitch up versus pitch down on the tear drop entries....this will confirm, or clear up any “over/under stabilization” issues. Are you seeing that significant velocities changes are changing the tear patterns or is a particular distance involved......Cheers, Ted, Merry Christmas and don’t let the trolls kill your mojo😎
In .22 with the 700mm slug A barrel I’ve been getting phenomenal accuracy using the MK 1 JSB knockouts. I would like to try .218 knockouts because my 600 mm loves .218 . I’ve been trying everything and whatever results I get I try to share on Facebook or the comment section of videos. So far with my experience you must keep testing and like Matt Dubber has said reg pressures play a big role in the accuracy
.25 cal nsa 36.2gr in the low to mid 900fps range out of the 700mm superior on my maverick is grouping tiiiiight
Hi Ted, thank you again for sharing your knowledge! I spoke/thanked you after 2017 EBR after I won sport class. I learned from your videos for years! Could it be possible if pellet wabble caused these tears at 100 that the spin and wabble would be at exactly 12:00 position every shot? Seems very unlikely to me. Thanks, and see you in competition soon! I have been on hiatus for a couple years, but coming back now. Thank you again for your knowledge! Whiteout it I could not have done so well in 17!
Nice to see you 😉
posting new videos bro
love your work you do 😏
Hi Ted. Was wondering. Do you think that the torque applied to the locknut of the liner system would make any difference to how the gun shoots?
Yikes!! Never even thought of that! Gotta test that at the range next time. 👍
I do belive it could make some difference!
I have been playing with torque settings and liner rotation.10 to 15 inch pounds works well for me
Yeah…there are a lot of variables that come into play with the whole liner system.
Like say, that 600mm crown barrel that stacks ko .22 mk1’s.
What are the chances of getting that liner into another rifle and seeing the data repeat?
My guess is…it wouldn’t
Even barrels in center fire cartridges same caliber and twist rate identically the same will have different personalities of wich bullet it shoots best. In my opinion your fx barrels will be the same way. The longer the projectile, the faster the twist rate will need to be to stabilize the bullet in flight. Key holes means to slow a twist.
I have a full spread of ST barrels. Came with my used Impact.
@10:00 - showing far. Bbls. . . Question: have you ever shot 5mm or .20 vs .177 or .22? Rsn: Sheridan (an old style pump airgun) was avail. late 70s and early 80s. Did not have access to a chrono, but, could get consistent placement in no or light wind at 50yds. No easy attach pastor glass, so, just later peep sights and OTS notch-n-post. Targets were bottle caps and sweetgum tree balls. Better eyes back then. Nowadays the airgun and my eyes don't work so well.
Still think adding the twist rate of the barrel is MORE significant than the FX name Sayings a xx gr slug or pellet shots better out of a 700 MM . 18 in twist than a 700 MM 24 inch twist has more significance than saying .superior. Light. Heavy. Old. New.Thanks for the effort I LEARN a lot TOM
I hope FX and JSB compensate you for all this testing time ! Would be sad if with all your testing you have other factors playing into your results , I.e. scope , mounts , wind etc giving you conflicting results ! Good luck and thanks for your sharing !
It could be the camera shake when the gun was fired, but I swear I saw the slugs corkscrew in flight. Could be an optical illusion, might not be either. Would a corkscrew cause the long tear in the target, or just the pitch of the slug on impact?
On most shots, it is an optical illusion. If you slow the video down, you can see it more clearly. I will likely add a few "super slowmo" shots next time to set everyone's mind at ease. :)
Still waiting on that maverick comparison vid TED!!! come on get your head in the damn game! I got starlings to kill but I can’t choose a gun until the god father shows me deeway!
Since they all keyhole the same direction it would seem the angle would play a part. It also seems the contact area of the slug vs velocity may play a part.
The Maverick is very interesting to me. I really want something I can count on.
I picked up a .22 Marauder a bunch of years ago and didn’t win the barrel lottery. I think maybe I should pull it out and test a few slugs with it.
Thanks for what you do.
Regarding tears in target...You didn't tell us where the wind was coming from? Behind then the back of the slug could be pushes down nose up. Thanks for testing these for us Ted. ..as far as the different liners go, how can I tell which is which? And what is the difference between the Superior and Superior Heavy?
The liners are all labeled, either with labeling tape or sharpie. Wind was from the right (south).
Superior Heavy barrel is more aggressive than the Superior. Faster twist rate, and possibly more choke (memory fails me).
Dreamline .25 600mm Superior Liner. Stacking NSA 29.0’s all day. Still not 100% but I believe the Huma pin probe made a significant difference in accuracy for me, not because of velocity but because it seats 10 thousandths deeper than the factory probe. That’s my theory anyway.
I only shoot the NSA 29.0 out of my dreamline anymore. At least until I get an impact or a Maverick.
Hello Ted, I have a few liners, one of them from a Dubber slugger. It only seems to shoot JSB Monster redesigned. What I wanted to ask is, have you noticed different rifling depth on your barrel liners? I have .25 Superior liner, and the land marks when you push a pellet are quite pronounced. The land marks when pushed through the Dubber slugger liner (which I thought to be a superior heavy liner) are almost non-existent. If you have barrels such as described, do you find the longer / heavier slugs don't perform in the "light" rifling?
I can not wait to to what your Maverick will do.. I have one coming from UA in .22 cal with a superior barrel.
Dude! Awesome video. Thanks for the info. One question, which length of barrel in the .25 cal STX?
All barrels tested in this vid were 700mm.
On the design of the pellet you aren’t just shifting the weight forward on the pellet you are also pushing the pellet into the barrel more or less to the groves of a given barrel , does that make a difference ? So many variables , I feel for you .
is it me or is the slugs destabilized on the video at 5:35... the STX 970fps segment? The knockouts? looks like its spiraling to me. KO.MKII
Very very good 😌 very very nice 👍
Hey buddy how are you doing I hope you are ok I miss watching your video hope all is good brother 🙏
The angle of the projectile is hitting the target at a different angle
Waiting for the next "I'm back video", again.
Malta JSB knockouts still hasn't arrived yet. I have a .25 cal 700mm STX pallet liner A and I am shooting the Barracuda Grizzly in 31 g slugs quite good at 864 to 835 fps . Have you ever tried the Barracuda Grizzly slugs ? Thanks for the tutorial you share with us Mr Biers.
Idea for you- what about a “public tuning spreadsheet” on Google sheets. Shooters can upload info to a spreadsheet with categories for projectiles, speeds, barrel, etc. Crowdsourced data may reveal some trends &/or help folks with tuning a new gun. Spreadsheet would be hosted on Google sheets & “public” so anyone can add their tuning information.
Keyholes were likely from the pellet tumbling
I see the FX Wildcat Compact has fallen by the wayside. Although as all know, it wasn't designed to be a long range rifle.
You'll see that wildcat smacking squirrels in the next vid (edit: on my main channel). :)
@@HoldOverVlog The original "Warcat" I hope? Mine has had extensive surgery, polished, tweaked, top after market parts, tested, retested, the list goes on. Why? To be reassured, not because it needed to be changed,......because I could. (Many of us, I have discovered, have the similar addiction.)
Ted, do you think the Mark 2's might work in Original Smooth Twist barrels (my .22 Bobcat for example)?
How much does temperature affect accuracy? Crown MKII in 30 cal. Reg set at 165 and hammer at max. FX 44.8. Had a group a few weeks ago that was crazy good. 4 in one hole with shot 4 just off a bit. Was about 55° with sun. Yesterday same range same everything. Group was closer to an inch. All this was at 50 yes. ES 4 SD 1.5. Group was not as good a chrony showed. Colder air in more dense. Just curious if you have seen this before
This should've been done by FX but Fredrik prefers to drive his McLaren.
The rim on the MK2 is thicker, weight distribution is different.
Hey Ted. Watched a video a while back about powerful new .22 pcp's and new heavy pellets. You noted that perhaps this may be the future for competitive shooting as the BC is getting quite good. I am thinking either a daystate red wolf or Fx crown. I would Love it in .22., as I have a FX Streamline in .25 already. But do you think .25 and .30 are still the choice if you wanted to get into bench rest or extreme bench rest shooting. I noticed a few good shooters using .22 for the one gun challenges but not sure how many would choose them for dedicated bench rifles.
I always thought that when the pellet wobbled it didn't have a clean hole within the target, hence the tear
Wouldn't you expect a wobble to be tearing in all 360 degrees? The paper all show a tear right above the main hole with maybe 10 degrees of variation like at 1:16. The theory of it coming in at a arc and edge of the hollow point grabs the paper on the way down makes sense to me. It's not consistent, though, like at 11:58. How does does back of the paper look? Is the paper split or missing at the tear?
@@allanwind295 does sound like a better explanation
Hello! How do we contact you to coordinate sending you free product? No review necessary! Just looking to hook you up. Keep doing what you're doing!
Just ordered the 2x10.5 donnyfl emperor v3..... what will this do to accuracy? I have an fx impact x mk11 in .30 literally just got it and now trying to hook it up I have a bunch of fx hybrids so I guess the next question is have you figured out the best power settings for .30 hybrids out of an impact yet?
Wow nice fx impack my dream airguns but only my dreams 😥😥😥🇵🇭
Hey ted, been watching you for a few years. Im looking for a super quiet back yard small game gun. Is there a gun with lots of power that wont frighten the neighbors?
Enything I missed?? Why aren't you making eny videos on this chanel an the teds holdover channel??.
Hope you are well🤗
Hello
I have a Maverick 25 cal. Compact Standard 500mm barrel.
1. Reg 175 bar 2. Reg 150 bar PW7 IHS?!? and shoot JSB Knock Out Slugs 33.49 Gr at 885 FPS. The Slugs Spiral !!
Does anyone know WHY ??
4:49 I legit thought that Mk2 group said "no good"
