There is a gilled style VZ858 muzzle brake which seems to be effective at reducing recoil and climb. You can read a fellow CGN'er's review here:
http://www.canadiangunnutz.com/forum/showthread.php?t=94717&page=123 I will be ordering one this Friday for my VZ and hope to try it out soon.

I was chatting with Palinak and Dr. Lector and this may also be a good design to carry over for the M305 rifle crowd. What do you guys think of this design and would there be interest if an M305 version was made available? I'm not sure what the cost would be, but the VZ model is around $65 CDN.
 
IMHO... It'd be loud as hell... Maybe I'm out to lunch on the issue, but I'd like to know just what effect it does have on the M14...

Cheers

It creates forward momentum using the expelled gasses counteracting recoil.
 
I think Jay means how much of an effect the muzzlebreak will have on recoil reduction rather than how it works, unless the excessive drinking we used to do made him forget physics for engineers.

Corey's got it... At the moment, I don't find my M14's recoil, so much as they sort of "pop" upwards a bit off the sandbags... The blast from that gilled break seems un-necessary...

I'm under the impression you would get less recoil and less muzzle climb for faster followup shots. The extra noise would just scare the bad people.:)
 
Not owning a M305 but currently looking for a good brake for my Nagant here is my opinion. I would look for a brake that is known to perform with a .308, there is a lot more gas in a 7.62 Nato over a 7.62x39. I would imagine that significant pressure change would change the charictoristics of a brake.

Good point. Maybe that should be investigated. Just screwing on a 7.62x39 brake onto the end of an M305 may not provide 'optimal braking' due to the full power characteristics of the .308. Anyone else have some input on this aspect?

I think its more of a ratio equation ....more gas larger brake or larger baffles or longer brake with more baffles. I'm sure it will be tested and optimized before or if it hits the market.;)

I have fired an FN49 in 7mm Mauser which has a 'gilled flashhider' .. recoil is mild. The 7mm round is a little closer in power to .308 if that helps.

Only the bad people standing beside or behind you. The trade off with a muzzle brake is that it directs some noise out to the sides instead of downrange.

I don't find the recoil a problem at all with my m305, but I'd always enjoy less muzzle jump. I'd love to see what this type unit can do if designed for the energy created with our favorite rifle.

More gass = better brake performance. Higher pressure gas = better brake performance. It's all good here.

It's true that you can squeeze more performance out of a brake by making it longer and wider to take advantage of a longer and more vigorous pressure pulse. The cost of that is the brake is longer, wider and heavier.
I put an A2 style flash eliminator on my full length barrel to drop 2" without any ammo performance loss.
I'd be interested in a 2 chambered, or maybe a 3 chambered brake; but no more. Are the vents wider at the top than the bottom? This is important to reduce the dust and dirt that gets kicked-up when shooting from the prone. I hate having to spit out dirt and leaves and clean my scope after every shot (another advantage the A2 style has).
I'd need the brake threaded 1/2"x28, and I'd take one for sure at $75.

You can have a look in here. I'm sure ideas will come.

All of those have 1/2'-28 threads. Some are ready available in Canada.
I hope it helps:)
 
I really like the look of the SSSB

This one. Doesn't look too long, looks really effective, I always shoot alone anyway and usually wear electronic muffs while hunting.

Who and where is it from?
