I was eondering about a Muzllebreak on my 30-06 and I wanna know if the bullet is gonna go slower cause of the muzzke break...

can somebody explain me how does this works
 
Don't know why installing a brake would affect the velocity. If your barrel is 22" to the muzzle, adding 2" or 3" of brake isn't going to slow the bullet down. If your barrel is 22" overall, including the brake, AFTER the brake is installed, effective barrel length has been reduced, and you are going to lose velocity.
Keep in mind that a brake will increase muzzle blast substantially.
 
Might be fun to "crono" with and without the brake however,
the pressure of the expanding gasses is behind the bullet as it does down the barrel, when the bullet exits the barrel muzzle it should go straight thru the "brake" area undisturbed in "smooth" air the same as if there was no brake, the expanding gasses are then re-directed by the brake and should not effect the bullet --- it should be long gone.
 
It depends on how you look at it. The portion of the barrel which is breaked - lets say it's 3" long - is not useful in increasing velocity - yet it is there. If your barrel was 3" longer than the standard length your velocity would be higher - especially in the case of over-bore cartridges.

I have chrony'd before and after with muzzle breaks without shortening the barrel. It has no effect on velocity... a break can change the point of aim though.
Exactly BigRedd. Does change POI. However I do have one on my Savage and it did tighten up my groups as well. But I dont use the break anymore either target shooting or hunting.
 
The brake is fine for time at the range, but DO NOT go hunting with it on your rifle. It temporarily makes you deaf for about 1-2 hours. I learned that the hard way this spring.

The loads I tried in my 338 shot to more or less the same POI, brake on and off.
 
A muzzle brake is about recoil reduction. That's it.

If you want recoil reduction at the increase of muzzle blast, they work very well. I have lots of different styles on the LR cannons. They do not negatively affect accuracy (if installed properly) or velocity. I don't hunt with these without hearing protection.

If concerned about recoil, use a different bullet/load or cartridge. A quality recoil pad will also do wonders as will increasing the overal weight of the rifle (that I don't like).

So do you really need that reduction in recoil during hunting? If so, think seriously about the effect it can have on you and those hunting near you. For the '06, you can easily make awesome hunting ammo with reduced loads. It doesn't have to hurt to shoot.

My walkabout hunting rifles do not carry a brake.

I was told that if the fins of MB are pointing at about 30° forward, than they create about equal amount of recoil reduction, but do not direct the blast at the shooter. There is a German muzzle break designer famous for his forward pointing fin breaks that sound about the same as the rifle with mo muzzle break at all, just need to find his name...
 
Sorry, but this is marketing hype. A muzzle brakes affectiveness is directly related to the amount and direction of gas it redirects.

Anything that increases amount of gas going 'forward' reduces its affectiveness.

If a brake is quiet, it is not doing its job as well. I can tell you from experience that forward venting brakes are not quiet. Been there, done that.

If noise is a concern, don't use a brake. If you want recoil reduction, it will be loud. Unfortunately, physics is physics.

Lets all line up and take sides... :rolleyes:
Hey there are legitimate reasons to use a muzzle break for hunting and it is not all about recoil either. When I am shooting prone at coyotes at long distance I need to be able to see my bullet strikes. I also need to be able to get back on target quickly when there are multiple targets.
I use a muzzle break on a .270 WSM T-3 Lite it is like shooting a very mild .243. I wear hearing protection... the coyotes don't care... they don't get to voice their opinion!:p
 
BIGREDD is 100% correct. Brakes serve their purpose, but hearing protection is a must. I have one rifle with a brake, and if I were to shoot it without plugs and muffs, it would be the end of what hearing I have left.
