Muzzle break question

[TC88]

Hey all, I have a Remington 700 ADL I inherited in 7mm Rem Mag. I plan on dropping it in an AICS or Whiskey-3 chassis (Sidenote, which I am still trying to acquire, PM me if you have one for sale!) getting a Vortex scope (to replace the terrible 4X Redding currently on it) and using it as a fun long range target rifle. I just started hand loading as well so I am excited to jumpstart this new hobby!

Ok, back to the chase. I am looking into getting a muzzle device installed to help tame the magnum and allow me to shoot for longer periods of time at the range in more comfort. The selection I found through good currny available in 7mm (.284) was, well, pretty non existent. My question is, would a .30 cal muzzle brake (or any slightly larger caliber brake) such as the Lantac 762 Dragon have any affect on felt recoil when a smaller caliber round is being fired through it? I would like a tactical style brake and the only one in 7mm I can find on google is expensive and (shallow as it may be) honestly cosmetically unappealing to me. If anyone has any experience or knows if you can fire smaller caliber rounds through larger brakes effectively your input is greatly accepted. Thanks!

GOOD CURNNEY? wow autocorrect... That doesn't quite spell Google. Sorry about that.

Don't break your brake!

Yup, you can go up a bit in bore size on a brake without losing much. Obviously you wouldn't want to go down, but the difference between 7mm and .30cal is really minor. Where you would run into a reduction in effectiveness is if say you were looking at shooting .30cal through a .338 brake. The problem stems from not enough gas being trapped behind the bullet as it passes through the brake. With an ideal diameter, the gas will "find" the ports easier and vent a larger percentage through them, which will make the brake more effective at dampening recoil. When the diameter is too large, too much gas flows with and around the bullet and less gets vented through the ports, resulting in less of a braking effect.

It's a similar situation with suppressors. While you can shoot smaller diameter bullets, the amount of gas diverted into the baffle stack is reduced and that affects overall suppression...a bit.

Damn, I know the difference between break and brake haha I can't believe I didn't get past the title without screwing up. Thank you for your response, going down obviously isn't an option but I'm glad .30 cal is close enough to work. There are so many options in .30 cal. Thanks again for your help and reply!

It's a common mistake, like "you're" instead of "your." Unfortunately, even manufactures get it wrong in their official literature. DTA had their brakes listed as "Muzzle Breaks" for almost five years before someone got a clue.

That's because after you put one on and it doesn't shoot as well, that say "that's the breaks"? JK...
OP, look around at some of the smaller companies, you'll find .284" pieces, usually radially-ported and the same diameter as your muzzle.
Testing showed a brake I.D. that was .020" over bore size was optimal, so a ".308" brake would likely work.

Clay Spencer makes some nice ones (web site blows) www.spencerriflebarrels.com

And PT&G is also selling some.

Good luck.

There's quite literally hundreds of different muzzle brakes out there. Many come with an undersized hole that must be drilled out to the final (bore) hole diameter by whomever is installing it. You may not find many if you're specifically Googling/searching for 7mm brakes but, trust me, there's a bunch that can be made to fit with the correct size hole.

Ross & Nathan can both be found @ muzzlebrakesandmore.com
Vais
Harrell's
Hollands
Etc, etc, etc.



Scroll all the way down on this page and look at the videos at the bottom for some comparisons of various brakes.

Ha! I know those guys - it's a small country.

This. I run a Ross brake- bought it undersized, and the smith that installed it drilled it out for me. Or Ross/Nathan can drill it out for you before they ship it to you.

You cant beat the price either.

I know a lot of guys running Ross Schulers brakes.

I know a lot of guys running Ross Schulers brakes.

I generally don't take the popular route when it comes to equipment, but I have a Ross brake. For some reason, I got the contour off by about 0.01. I had it installed at 700barrels, and it came out pretty nice.

For $45, you can't beat it. It crushes the hell out of the cheapo shim types that cost more. It's ideal for the smaller cartridges when you aren't looking for a Barrett brake and just want to tame the lift a bit.

Ross will make you one with your specified exit diameter.

I also like the JP Recoil Eliminator, most efficient brake I have ever used.

Well, here's a selection:

http://www.midwayusa.com/find?usersearchquery=Muzzle+Brakes&itemsperpage=20&dimensionids=4294845964

Note how many are for 7mm/.284 caliber. Any gunsmith worth his salt, and preferably with all ten fingers, can fit a muzzle brake. I ususally buy one and send it to the barrel manufacturer for installation along with an order, or have them equip a new barrel with their own brake.

Last one I sent out went here: http://www.magnaport.com/rifle.html

This is the Mag-na-brake, not the EDM porting. I just stripped the rifle down and sent them the barreled action. In this case I ordered the 220 degree varmint brake with no ports on the bottom that blasts dirt off the ground or blows your half empty coffee cup off the bench. My nasty recoiling Cooper in 6.5-284 was tamed down to shoot like a .22-250 or .243 Win.

I love my Ross Schuler, Great for price and works excellent custom made just for my barrel, had Randall install it and it was perfectly timed and really helped with recoil.

Are the Ross brakes really loud compared to other baffle style brakes?

No brake on my bolt rifle now b/c it's heavy enough and doesn't kick hard enough imo to bother or fatigue me. However, a very loud brake would get annoying to me, more so than a the little bit of extra recoil, but if I can reduce recoil and muzzle movement w/o much extra noise/blast, why not.

Also, I'm not 100% sure about the validity of this or how it was explained, but supposedly the military tested and confirmed this with their 50 BMG rifles + brakes: I've seen a thing here and there online explaining how for larger calibers (aka not really applicable to 308, 30-06, etc and below) having a brake can actually throw off your shot slightly (but in an inconsistent manner), even when mounted and used correctly as the air in the sitting in the barrel in front of the projectile won't necessarily act in consistent manner and pulls your rifle off to 1 direction as it exits the barrel and enters the brake as it's being pushed out by the projectile behind it. However, (without having taken fluid dynamics, studying air flow, etc) I would also imagine that this effect would be more noticeable in a Barrett 50BMG style brake vs some other designs. If anyone has more info, please share.

I dont know of any true brakes that aren't loud. If it works, it's loud.

If you werent in cali, you could buy a suppressor which severely cuts the recoil and the noise....

Brakes work on mid sized rifles such as 308/243/260 and 300 win mags and bigger... quite well. The more powder, the more gas. The more gas, the more gas is redirected by the brake....

I thought it would be funny to buy a VQ brake for my 22 pistol.... I dont know if it was the brake reducing recoil, or the 5 ounces I stuck on the end of the barrel.....


I know lots of people running brakes on their competition guns.... None of them have issues with accuracy because of the brake.
