Discussing Barrel Tuning & Barrel Harmonics with Buck Master GunSmith

I was talking barrel design with Buck and it sparked a barrel harmonics conversation so we recorded it and later added some pics. Some people think a steel barrel does not move, expand or vibrate when shooting and those that know it does move does not understand how it can change accuracy and precision shots.

Thanks rick this is joe (on my wife’s account ) hanging out working overnight patrol on college campus up in unconstitutional state of Connecticut dealing wit drunk young liberals doin things like crashing cars fighting each other running into water at beach naked wit horse head masks on for a sorority pledge on this thirsty Thursday but after all that since midnight i seen you posted a video an that made my night

I have really enjoyed these conversations with Mr Stienke. Something about the atmosphere of the small business and the shared wisdom of an elder, broken down for the layman. Reminds me of when I was a kid, working in an old fashioned hardware store. I think, I learned more in a couple years of part-time in hardware store work than I did from my 12 years of government public-education. Please keep making content from conversations with Buck. I know who I will be ordering my next NFA item from, when the time comes.

Great video thanks for the education rick and buck

[@maytronix7201]

Best explanation I've heard for that. Much obliged.

[@levimartin3056]

I found my new soul mate. The Banshee chambered in 5/7. I need to stop watching gun reviews. I fall in love every month.

[@pstewart5443]

By far the single best explanation out there in relation to this topic. Great job. Thank you for the definition. I was like wow, I dont have a clue what that word means. Insert definition....awesome, now I don't have to stop the video and go learn a definition then come back!

[@HeyGunPeople]

Glad it was helpful!

[@mr_fnh]

Thanks for getting us this info Rick. I could listen to Mr Buck speak all day. Very fascinating subject.

[@artt3165]

Thanks Buck & Rick! I spent a good amount of time designing tuned exhaust systems for racing and it sounds like a lot of the same logic and theories apply. Its MUCH more intricate and complicated than just sticking a tube with a bunch of baffles on the end of the gun.

[@road_warrior_1]

I can't believe I'm just now learning this wow incredible knowledge

[@iamtheomega]

I always wondered how BOSS worked, this the first/best explanation

[@gateway8833]

Excellent explanation of harmonics. You want some interesting math, try figuring this stuff out. It made me cry a lot in school, because they never told me when I enlisted I needed rithmatic. They said all I’d be doing was jumping out of pine trees killing people. They lied, they don’t let Marines climb trees as a rule.

[@thinredline1102]

Great video Rick. Very informative and interesting. My God the knowledge this man has is incredible Your one lucky dude! Kinda reminded of that scene from the movie shooter... Lol 🇺🇸

[@floridaplumber7512]

Nice video, never cared to get suppressors, but now I see the benefit , thanks

[@kurt6410]

good to see you back in the saddle

[@hotrodray6802]

Excellent. Thank you.👍👍😎

[@Compton2952]

Goooooooooooood morning Rick, Buck and the Boys

[@randykyzar9194]

Thank was a really well done review Rick I enjoy information of that nature. Hi Rick I gotten a 185th anniversary Gretsch

[@roquri]

Had guns with a B.O.S.S. system on them. It works. Wish you could still get it on Winchester, and not just Browning.

[@wldtrky38]

I have always considered that precision handloading, finding that "sweet spot load", probably had something to do with this exact thing. I mean we are actually tuning a load to a particular rifle/barrel. Beats me, lol, sounds good tho. Thanks Buck for your time and expertise, thank you Rick for getting the vid. Y'all have a great weekend !!

[@C-Rocks]

Thanks Buck!

[@rudolphferdinand3634]

The Browning/Winchester Boss worked as it was designed to work , excellent. I had a Browning A-Bolt in 300 WSM - accurate.

[@erictrunick5496]

How accurate were you able to get? Groups and yardage?

[@saranobutt]

I ahve no idea what's going on, but you guys have such cool weapons and even parts of a gun are cool.

[@Compton2952]

Stick around and learn something grasshoppah.

[@singleguylifehacks626]

If I were Buck I would make bumper stickers to advertise my business. "Need a gun repair? Put some Stienke on it"

[@skyrimluvr1442]

♥thanks guys, for the great info♥

[@rubenvillanueva622]

An excellent physics lesson, in a student friendly environment!

[@tylerford88]

Thanks for recording this, and the dictionary screen shot ha. If you haven't seen it the sniper 101 here on youtube series has hours of good info like this. I listen to it while I'm driving because its like 100 half hour videos on everything.

[@mare6684]

Another good video!

[@keitha.9788]

I have a Browning A-Bolt rifle with BOSS, and you can indeed "tune" the barrel to get a very small group size...

[@SnipeU696]

Thank you.

[@El69Fuego]

Doesn’t fluting help dampen the harmonics? Learned that as the outward waves impact the fluting groves they are severely deminished

[@guido1534]

Damn is that a smart man

[@SheepDogNumber6]

Awesome.

[@wonkachocolates6133]

Questions : (1). Does the weight of a "muzzle device" greatly affect accuracy with barrel harmonics..?? (2). Bore temperature; Is COLD more accurate than a HOT barrel when comparing shots.?

[@darkstar7721]

Does mossberg 12 gauge 590a1 with heavy barrel no rifling still flexes

[@milonjano]

The neutral 'nodes' (as you say) is when the barrel is at max whip velocity. The upper or lower peaks is when the barrel is actually stopped.

[@drd1924]

Noides are when the harmonics/vibrations cancel each other out thereby dampening itself ineffect. Just like 2 speakers 180 deg oyt of phase the noise may be at maximum volume but the sound is camcelled. You are correct the upper and lower peaks are when the barrel may have actually stopped BUT BUT. you do not know where that stop may be in the X,Y plane whereas the bore may be pointed left or right of center at an upper or lowest peak.

[@shelleyyates6855]

Hi Rick, Hi Buck, Big hugs to all n the boys, missing them Rick, when are you going to do another video with them n Mokie-moke x

[@Mykoe9]

Oooo, thanks for that Rick , I really appreciate you putting this up, I always wondered about how that actually took place as the bullet is fired through the barrel. Man, that's amazing how that all works together like that, and finally having it explained so that I (who don't know nuffin but the next chord in the song) can understand it. See, I've been told that when the bullet leaves the barrel, it drops low and then rises back up to get where it's supposed to be at a certain point in its travel. That didn't sound right to me. Could still be true but something about that doesn't sit well with me. Thanks Rick.

[@Mykoe9]

I'd still like to hear more, and I think we were about to delve into the tuning/how to before the customer came in. Please thank Buck for me . What an interesting feller. ('at's the WV in me coming out, sorry)

[@itsnotfar]

Great video. How much for the talking moose up on the wall.

[@jasonfischer1530]

Hey Rick, can you do a video on Washington State Initiative i1693?

[@2wheeleddemon999]

I would travel to see this guy and shop at his store. We have a few good places here in Houston but they mostly just want to tell you how tactical they are and sell you expansive crap that you will never use.

[@BIG1ED2]

Good vid Rick... 🤪🤪🤪

[@mef9327]

Hey Rick. Did ScrewTube finally let this account out of time-out? Glad to to see you're back. Great video BTW

[@jacobwhite936]

Rick, could you ask Buck about adding mass to specific places on the barrel to tune out the harmonics? Example: Adding something like a collar clamp around the barrel or would it limit the expansion of the barrel as the bullet passes through that point?

[@HeyGunPeople]

bigger thicker barrel will help but heavy and more material and money

[@jacobwhite936]

@@HeyGunPeople I was thinking more like a piece perhaps an inch long that could be moved along the outside of the barrel to add mass to only a specific spot. That way you could tune the barrel by changing where the extra mass was. I know from precision machine balancing and from doing audio engineer work that harmonics can be tamed by doing something similar.

It's been awhile friend. Be well :)

[@ideclinegoogleuseragreemen8183]

ohhh yyyyeeesssss

[@SOLDTONORM]

Random thoughts...It seems that the only effect that would create a vertical standing wave would be gravity. The spin imparted on the bullet should actually create a helical wave (hold a piece of rope vertically and rotate it). Note that the nodes are still centered in the wave. The suppressor is not a monolithic mass. The mass might be greater at the base, moving the "node" past the end of the barrel but not to the end of the suppressor. While "bull" barrels are more resistant to bending and cancel out some of the vertical wave, the twist of the helical wave is resisted by the barrel mass that is far from the center line by leverage. Watch slow motion of a recoil and you will often see the rifle twist in the shooters hands by recoil from the accelerating bullet mass (greater with greater bullet diameters and masses due to leverage).

[@Cageey1117]

On an AR-15 a vibrational wave travelling 20,000 fps will cover 32 in. (2X barrel length) in roughly .000133 seconds. Over .003 seconds the wave will oscillate along the barrel 22.5 times. .003 seconds is the elapsed time of the firing sequence from trigger pull till projectile exits muzzle. You can take that to the bank.

[@REDNECKROOTS]

There no way soft copper n lead is bulging the barrel as the bullet goes through it. No way thats true.

[@travisruble6873]

No, but 60,000 psi will.

[@caldylangoss2287]

[@GTMGunTotinMinnesotan]

Did some research on the claim that cuts in the barrel will add to rigidity. All the top barrel manufactures say it's not so, that it's a common myth, that it's only for cooling purposes.

[@adamstoeffler3678]

He did not say it would add rigidity. He said it would cut down on the weight while maintaining (more or less) the same rigidity as a barrel of the same width.

[@SniperOwnageLol]

Why are the majority of your videos on private?

Is there any way to access them here or on a different platform? I'm a late viewer to your channel, so I haven't seen any of your other videos.

[@Oldtimecarpenter]

FLORIDA PLUMBER your not worth the comment!

[@br4713]

If the barrel is stiffer, it will have higher frequency harmonics and will be harder to tune

[@prone_wolf8871]

True, but you also won't have as much movement to tune out.
