These are the times I miss Barry the most. He would dumb it down and laugh it up!
3 and 5 groove barrels distort the bullet less. grooves wider than lands help reduce pressure spikes. angled land edges (not perpindicular to the bore) help reduce copper fouling and make cleanup easier.
Robin Snodgrass better explanation than the video!!!!
Dug Kub Thank you, I do try...
Robin Snodgrass
Nailed it.
Yup, that's what I was thinking too.
So what about Marlins “microgroove” rifling??? It has 12 shallower narrower grooves. I understand the theory behind them, I just need someone to make high speed camera footage by inventing transparent steel!!!
I'm so freaking happy knowing there are people in this world that can afford to know what these two just explained.
Hey guys. I spent 21 years in a crime lab looking at bullets. There's tons of 4R barrels out there too. Also, almost every firearm S&W ever made was 5R . Notable exception was the first .40 S&W's - they were 6L.
Where is the video comparing the 20" vs 24" barrels on these 2 700's
Thanks for the knowledge and what the difference between a 5-R rifle is.Also the visual aids on showing the groves in the barrels that you mit have. Great Job guys IV8888 for life
Great video! I've been gaining knowledge about various guns and you guys have really helped! Thanks and keep up the good work!
You learn something new every day! Love these facts videos, thanks guys!
Just bought a TC Compass in 6.5 Creedmoor. It has 5R rifling. I am amazed at the accuracy out of a gun for $330 with a $75 rebate!
Thank you, i missed these types of videos from you guys. Thank you for the information.
That was a nice short, yet informative video. Loved it!
I have a Rem 700 300win mag 5R that I changed the stock and put a accurate break on it and wears a older night force. I was always a 308 shooter. I’m loving the 300 5R. Nice set up ty for posting
I'm a writer and I need to study the technical side of guns, and this is really comprehensive. Good work boys!
So funny. Thanks for the video. Very informative and entertaining! Keep it up
Love my Criterion wylde. Definatly a difference in velocity and accuracy from my other barrels.
Thanks for the information brother. This is cool stuff I've always wondered what 5 - R ment.👍👍
Great information, I did not know the difference. Thanks!
Great video! Thanks for the explanation. 👍🏻
That’s a very well informative video!
Thank you for the great info!
Love your videos keep up the good work.
I liked the point about not needing to nitpick about barrel rifling if you can’t shoot under an inch anyways, because for beginner shooters it seems like if you shot 2” groupings with a sub MOA rifle you would shoot 2-1/2” or 3” with a single MOA rifle, but this is not the case. I would say however that the rifle you feature in the video is a good rifle for beginners because of a point made earlier in the video: you won’t need to make many upgrades as you get better at shooting and you’ll be able to see the effects of accuracy upgrades. There really isn’t anything wrong with buying a gun that shoots tighter than you can, it’s just a little more expensive but most of the time buying two guns or one gun and swapping out all the parts will be more expensive anyways.
Have a 5R Satern barrel from Brownells in my DPMS pattern AR10 I built, shoots .5 MOA and cleans up easy, couldn't be happier with it for the price.
i knew this was going to be technical as soon as i saw chad wearing glasses. very interesting guys... thanks!
5R is like 223 Wylde----it's not necessary for a good barrel but take an otherwise good barrel and add it --- and they'll really be next level.
Mrgunsngear Channel I have a Aero Precision 223 wylde barrel. Does that make my barrel next level compared to barrel chambered in 5.56?
in terms of your rifles ability to burn through civilian and military ammo supplies without suffering from either erratic patterns or increased wear and tear then yes.
.223 wylde shines in a situation where the ammo you have access to is random and inconsistent, while not suffering significantly from said ammo randomness.
Stfu Mr. Clean
Ashley Weeks
Lol.
So my 5R bull in .223 wylde should do just fine then. After I build it of course.
I was just thinking about some of the Enfields having two groove rifling and then you guys said it moments later haha. Very interesting video though guys.
Still really looking forward to that 20” vs 24” comparison you’ve talked about
I have learned something, thanks guys.
hey guys love your stuff keep it up
Thanks I learned a lot from that one right on
Excellent video!
FINALLY another Firearms Facts! :D
Would be very interested in seeing a video on different types of rifling.
I want to see a video talking about the history of the Mauser action and all its variants, theirs sooooo many.
You should do more of these types of videos. Thanks.
Have a Remington 700 magpul and it’s amazing it has 5-r rifling and a magpul hunter 700 stock and magpul bottom metal all from the factory.
Groovy man.
I'd like to see that video about the military style riflings, this is interesting stuff for engineers and gearheads.
Hey guys love your channel!! Just a heads up HENDERSON PRECISION just came out with a motorized case trimmer that is awesome I think if you have time you should check it out. I purchased one and it makes brass prep suck much less and it looks cool as a bonus
My Smith M&P 15T has 1/8 twist with 5R rifling, free floated quad rail over 500 rounds so far and no failures. LOVE IT! I feel like you guys could make a good video on it.
Been over 4 years, how is that M&P doing?
@@Tux7.62 I sold it last year but it’s a fantastic rifle
love that stock! i have an h-s precision on my 700
Love Chad's new glasses. Very cool.
Great video.
Cool vid guys
I love these rifles!!!
Have had a Remington SS 5R Milspec in .308 for years now. Has a few choice Seekins items bolted on and a Zeiss Scope, plus QuickSilver moderator. The only thing that matters is "it holds it there" whatever I do and pretty much whatever I feed it. Give it some Hornady factory and its under 1/2"; the "exactly what" is me. Just keeps on delivering the same year on year.
The point I really want to make is a well sorted rifle combination will give the harmonics that "hold it there" and whatever the rifling doesn't matter. Some barrels seems to do it better than others. Might be the barrel length, or contour, or just general stiffness. The 5r's seem to be pretty forgiving ammunition wise. Certainly my Mispec is working. To me its all in the overal harmonics to ammunition that give the result. Which is why some rifles just "behave" better than another. All that load development is to find that sweet spot; just nice if the chase isn't long. Better still if its found with a wide range of factory loadings.
Once you have a rifle "holding it there" then leave it alone, its a keeper. It would be nice if there was no luck involved, and the lapped custom barrels try to remove some of that luck, but call me old school but for all the science I still think there is a tad bit of luck involved with any barrel/rifle combo. Some rifles just want to shoot straight. 5R as a rifling has merit as well behaved, even with factory fodder.
Other than the fun of it I'm not sure a side by side test on two "sorted" rifles proves much other than how they play with the individual shooters that day. Nice to know what range of ammunition it keeps it there too.
But its fun, any excuse for some trigger time.
This is good because I’m looking at getting the SPS barreled action from Brownells but the 5-R seems good also. I’m torn
Cool. Just got the TS Compass 308 for 199 shipped after rebate. Has this 5-R. Rebate already spent on a 995ts. :D
Shoots good so far. Break-in time still.
Did you guys ever do ta video on all the different types of rifling... really would be very interested in hearing what you have to say regarding them and how they all compare.
Idk where else to put this Eric but recommendation for a top 5 gun video? Top 5 most accurate guns for the money ("for the money" as in common calibers, "accurate" as in actual accuracy without regards to recoil patterns, cosmetic/comfortability, etc. & under 600 yards)
Hoping to see an update on the comparison between the 20 and 24 inch rifles soon!
Would like to see some best 100 yd group videos with any rifle bolt or semi auto and try to debunk that bolt guns can shoot better than a semi auto. I have an 18" Criterion on my 223 AR and love it.
Happy Easter! :-)
The matching glasses DO make u look smarter and more capable of answering the question! But is Chad smarter because his glasses are bigger?? Ha! Great job as usual. Wanted to know the answer to this question also. Thanks!! Keep it up!
the comments are very entertaining after a good tech video
You guys need to do more videos about this type of information....or maybe a bolt gun build.
Would love to see more rifling vids
Lol, I have a WWII Rock Island 1903-A3 Springfield with a pitted bore cut to 18.25" w/ Timney trigger in a full length glass bedded plain walnut Mannlicher stock and old (1974) fine crosshair Weaver 3x9 scope and is a 4 grove barrel. It has 4 hunting handloads in 150 gr & 180 gr (Sierra hunter & Nosler Partitions) that shoot under 1/2", usually clover leaf 5 round groups at 100 yds off the bench on bags. I haven't seen any 30-06's shoot that well for for under $1,000. Must be the 4 lands & groves :)
Excellent
Good description about accuracy vs practical accuracy. I did not hear when you described a rifle "ecosystem" (odd way to put it but it is a system and the more things you can control the better the performance) one of the key things. I postulate like a Henry or a well built lever or bolt or straight pull or falling block, not one rifle on that list is more accurate than its sights. do you have a video on that? Shoot safe while aiming small to miss small.
Really interesting channel
My tika t3 and blazer r93 with good factory ammo shhot half inch easy my Remington 700 inch with home loads all are better again , but tika n blazer are accurate strait out the box, great video wise words
Hmmm, just noticed the barbed wire assault bat hanging up. LOL. Nice! 😀👍🏼
Would love to see the chrono test video!!
I have a Faxon match series 5R in my LR308. with my hand loads it shoots .5 to .75” all day long. Pretty darn respectable for a gas gun.
Hi My old .303 only has 2 lands it shoots great.
Cheers Rory
Deep!
I have been looking at Sabatti's MRR,(Multi Radial Rifling) that has spherical lands and no sharp corner for fouling to build up into. Interesting concept with claims of less bullit distortion and higher velocities. Stating some 10% higher velocities. Like to hear your take on this! I shot one of the tactical rifles with an extremely light 1lb trigger that was amazing. Simply thought about the shot and it went off.
I was intrigued by the fact that Sabatti has been around for 400 years,(second to Beretta). Check them out!
"Copper fouling" can be a good thing. It fills in the low spots and shuts the gas leaks when the bullet travels down the barrel.
Never heard of barrel polishing bullets before this video, guys. Thanks. I've seen chattering in my barrel's rifling (grooves).
Good video
I've owned a 5r rifling melonite barrel ar15 for years , I never got rid of it because I was told 5r rifling is really nice to have , I never knew much about 5r rifling though and how much of a difference it actually makes in real world tests . Thanks for the video on it . If a test was ever done on this please point me in the right direction. Thanks .
@R P, is it a S&W M&P sport15?
I'd watch a rifling video for sure
Good video guys....👽
Would be interesting to see if the bullet retains a stable trajectory out to greater ranges with a better finished barrel or with 5R.
Firm believer in it being more about who does it than what it is
I would like to see the video on the different rifling patterns. That would satisfy the gun geek in me.
I'd really love to see a video on the .375 Holland & Holland Magnum cartridge. I feel that it's been pushed out of the limelight by chunky rounds like .458, but it's a serious butt-stomping round. Great content guys!
Kenneth Compton the 375 hh Is a hard hitting round i got to shoot one at the range one day it's an awesome round and has a good thump
My father always used his Sako chambered in .375 H&H, never saw him miss, always bagged us dinner
Iraqveteran8888 Hey Eric, I’d really appreciate if you guys would do a Ruger 10/22 meltdown video. Thanks
if you do that rifling video, please include polygonal rifling. thx :)
More Precision Rifle videos guys PLEASE!
Finally a 5r explanation..I have a M&P 15T with a 1/8 5r barrel and I had no clue what it meant
Pew Pew Moto which one? Quad rail or new mlok rail
Pew Pew Moto I got the quad rail one
I too have this rifle with the Quad Rail. It's awesome
Yeah I originally had the quad rail however I took that one out and put a Midwest industries 15 inch mlok rail
Time for an update on this topic, guys, did you have the chance to see a Sabatti rifle with MMR ? Take a look at it, it’s very interesting. I have a few friends of mine shooting those kind of rifles and results are impressive.
Shneider barrels originated P5 rifling, this is their description:
The second rifle form available, in addition to the above, is our innovation we refer to as P5 rifling. Some refer to it as "polygon" rifling. Most shooters when referring to polygon have thoughts of the European pistol barrels. Ours however is different but has similarities. Some of our customers call our rifling polygon and that is fine with us, however we call it P5. Have to admit the "P" in P5 does have an association. What is different? Most shooters have looked thru a standard barrel and observed the rectangular shape of the lands and grooves - very well defined by the sharp corners at the transition of land to groove and at the top of the land. The P5 however displays no sharp corners when observed. The sharp corners have been replaced with a radius. The net effect is better seal of bullet to barrel and less damage to the bullet preserving its integrity. The most profound result is an increase in bullet velocity. This is not subjective, a chronograph can measure it. In some instances an excess of 100 fps have been recorded. Another attribute is the barrels foul less. This is subjective; however our customers have been consistently reporting this observation without solicitation. What is telling is the fact that the P5 rifling represents 97% of our sales compared to the conventional rifling and we do not advertise
Both Obermeyer and Shneider are rarely mentioned outside Benchrest circles, But Krieger does give Obermeyer credit in their literature. I thought both Men deserved recognition here.
My Criterion has only 4 grooves(which is their standard for 30 cal) that also are not square cut. And yes the muzzle velocities are fast.. also the 5R rifling is not square cut it is taper cut to allow better gas sealing and easier cleaning.
Could you please do a gunsmithing video about hand lapping barrels
Has the testing be conducted with these 2 Remington 700s guys? Keen to see how the two different length barrels went as I have one on order (24” Gen 2 in 300 WM). Cheers.
I just ordered one to day
Can you take a look at this new 9mm pistol: Sarsilmaz SAR9.
It`s a combination between a Clock and a Heckler & Koch.
Looks cool, reliable and affordable and is from Turky.
Got a pound and a half two stage trigger on my German 22lr. But i got two pounds direct triggers on my 222 and 243. I like it like that.
🖖🏻🇫🇷😎🇫🇷😇🇫🇷🖖🏻
not a big Remington guy but that is a sexy gun. Their QC still scares me too much to spend $ on one myself, never less they have a few cool options.
nice!
Chad Kent?? mmm take care with green glowing crystals (also red crystals) That explain his accuracy, he shoot and in mid air correct the trajectory, and our terricole human eyes can't see that. :D Thanks for the video guys!! Greetings from Chile
There is a lot of renewed interest in 5R rifling, due to the new Thompson Center Compass, a "budget rifle", with 5R rifling and their MOA guarantee. I just purchased a T/C in .243 (6mm), and this lived up to the guarantee after shooting approximately 40 rounds, and seems to be getting tighter as I shoot it more. I also have a 60+ year old Remington 722 (.222 Rem) that easily shoots 1/2 MOA, and it also has 5R rifling.
Perhaps y'all could do a review on "budget rifles"? Thanks again for being my #1 video content channel
5 groove rifling was developed for the Enfield P14, and carried over to the M1917. 5R is a polygonal land technique. I don't think y'all quite appreciate the difference. Polygonal rifling brings a lot to the table, even if only 4 - groove (the AK74 original pattern).
Nice
If I'm not mistaken, 5R wasn't even designed as some mega accuracy rifling, it was designed to stay cleaner. Mosins seem to do fine with three groove rifling.
I have a McGowan hand lapped 6 Grove barrel that will shot 120 ELD match 6.5 creedmoor through the same hole. :)
I think I saw on the Savage 5R rifling that the lands are cut more like a pyramid with angled sides as opposed to 90 Degree vertical sides.
Bigbore --- you are correct, they only explained half of what 5r is.
Because they are no where near the "experts" they claim to be, just like so many of the so called "experts" on joke tube.
Hey Eric & Chad, very great video 👌
Btw can you guys make a video for the best Budget AR-15? Bcs i would like to buy it but i don't have an idea which one to choose.
Thank you 🙂
It might not be exactly the answer you want to hear, but the best budget Ar-15 is the one you assemble yourself from a reasonably priced stripped lower. ~$60 for the lower from your nearest FFL and you are started on your way. Build it the way you want the first time. $1000 for the finished rifle with the parts you want is cheaper than dumping $700 worth of parts into a $700 factory rifle to make it the way you want. And when you assemble, you can spread that cost out piece by piece over months so your bank account doesn't take a big hit all at once.
Ive got a Left Hand, Savage 10T, 6.5 Creedmoor, with a 5R Barrel. With good ammo it's shooting .5-.6 MOA. After 150 rounds the bore was almost spotless. Cleaned up with about 3 patches. Now if I can just get it to eject better...
Bumble Bee you don't need match ammo to group like that with a 6.5creedmoor. Most cheap stuff from Walmart or academy will group as good if not better than match from hornady or federal.
Bumble Bee how exactly are they being "sold a bill of goods"?
Shoot what makes you happy and if your semi custom hunting rifles make you happy then drive on... I also like to shoot Bullseye pistol and M1 Garand in CMP matches also...So...
Bumble Bee it's weird to see someone so upset over what caliber people prefer to shoot. My comment wasn't meant to offend but just stating my experience
Bumble Bee have you heard of the new 224 Valkyrie? Rumor has it that it can drop a moose at a thousand yards?! Best Caliber currently made....getchu one.
