Muzzle break on a 15-22. REALLY?

I understand he said "rapid fire". Why care about vibration/harmonics? Hello!!!...= better accuarcy! And if these results are the same from bench, I WANT ONE!!!

As for barrel length, there is a reason sniper rifles have long barrels. And even at the much lower muzzle velocity of the .22lr, the round has left the rifle behind long before the barrel rises.

You bet there is - velocity, not accuracy. The difference in barrel length on accuracy is minescule but theoreticlly shorter is more accurate. Look at benchrest guys, they shoot short barrels so that there is less barrel movement. And yes the bullet is gone before the barrel rises but the barrel can and does move from the time the trigger is pulled and the bullet leaves the end of the barrel. A couple inches at 1500fps+ in like I say minescule but if you are looking to ring every thousanth of an inch out of your group it can make a difference.

Well, I'm certainly no expert, perhaps there is a middle ground sweet spot too? I know it's more about sight radius with pistols, but from what I read, a 20in 22 rifle will generally be more accurate than say a 16in. Now you got me wondering lol.
 
Ah didn't see the rapid fire part.. ill have to agree weight on the end of a barrel does seem to steady a rifle off hand but id say its mor of a muzzle flip thing than anything else... shorter barrels are usually used because of less vibration and less chances of defects in the rifling and lands themselves with that said sniper rifles have long enough barrels to sqeeze every last fps out of a round just to make it flatter shooting and a more reliable burn everytime (less differences between fps shot to shot) but with custom hand loads where you don't need 4000 fps to shoot 1600 yds a shorter barrel is usually prefered.. or atleast this is my understanding if more was better then bench rifles would have 30ft barrels on them..lol

I would definitely care about harmonics under the right circumstances. I just don't think that during rapid fire, in any gun, that it matters enough to warrant consideration. The movement of the gun caused by recoil has a 1000 times more impact on accuracy than vibration. Like the other poster said, for squeezing out every 1000th of an in, you bet! But how you going to do that during rapid fire?

Either way though, I agree with you. . I want one too! But that probably won't happen any time soon lol.

And I'd have to agree with BeltFed, he most certainly know more than I. 30 foot barrels! :eek:

okay well this got put in whole different direction... I thought you guys watched the surefire video I posted and understand what I was explaining

I actually went out and took all my accessories off and left the A front sight and rear MBUS..

Yes rapid fire of 25 shots @ 50 feet

Left is the standard bird cage and right is with the MB556K

sorry I didn't have anymore of the same target paper available

Pretty definitive to me.
 
Speaking of long barrels, oversized scopes and slow bullets..;-) phil I've got a new toy you need to play with.. that mkII trr-sr is crazy.. with aguilla standards at 40rds a 10 shot group looks like 3 holes.. can't wait to shoot it at 250..
 
Yes u do.. we r going to try and get some trigger time in Monday or Tuesday with myfriend that does the sniper comps.. he is all tore up they r having a 1600yd bonus target this weekend at the shoot in ky

1600... :cool: Way out of my league. I'm just learning how to shoot at 200-500.... I could sure use some pointers from you guys. Will talk on PM so to not clutter up this thread.

I am totally in agreeance I didn't see the rapid fire in the original post and as soon as I seen that this wasn't out of bags all arguements from me r off. Heck my groups vary that much between mags.. there are many more on here that know way more than me all I was stating was Hatchers findings that a certain mass at a certain point of the barrel reducess vibrations and will tighten groups up.. With that said no bags no test period.. I really got in to those books a few years back and read a bunch of therories and thoughts but Hatcher really puts his money where his mouth is so to speak. And the only reason I was reading was purely selfish, I was getting beat in matches and I wanted to know why.. when I knew my gun was built to tighter specs.. but it was all in tuning
 
Those are great results. Is there notable difference if not shot rapidly? How much is that muzzle break and is there a link to it?
 
Just to clarify some folks have been using flash supressor and muzzle brake as if they were one and the same - which as far as I am aware is not correct. The flash supressor, well supresses flash, which unless you are shooting at night is really not an issues - especially with the 22LR. The muzzle break on the other hand is a device that diverts propellant gases thereby reducing perceived recoil, and muzzle rise.

Also while I am sure barrel harmonics exist - going back to my college physics I am pretty sure that in order to counter balance the harmonics you would need a very specific 'weight' which would vary depending on barrel length/weight/thickness/ammo and would not be something that would would be 'plug and play' between rifles.
