Accuracy and Brake

[bsekf]

I realize this is mostly subjective. However, have any of you put a brake on a ued barrel and found a change in the accuracy? Do you believe a brake effects accuracy? Any reccomendation for a particular brake?

I am interested in a brake because I want to see the bullet impact.

Thanks,

Bill

You can search the forum for "brakes". In the meantime, http://forum.accurateshooter.com/index.php/topic,3778221.0.html

Hogpatrol, Thank you so much. This is exactly the information I was looking for.

Not to throw a "monkey wrench" in the mix here (and I am certain people may take issue with me on this) but I absolutely disagree with some of the points on that posted thread.

Some brake designs are absolutely counterproductive to accuracy and it does not matter how well you install them, chances are accuracy will decline with their use. Other brake designs are fine for accuracy and have no ill effect on accuracy, in fact they can improve accuracy.

The other issues with brakes relate to having a puny threaded section right at the muzzle where it actually stresses and slightly deforms the muzzle so it then fails to shoot well. Stay away from 1/2" threaded brakes if you want accuracy, and 5/8" threading is also marginal. Avoid a relief cut section behind the thread as well if you are going to use a smaller threaded section. We just had some brakes made up with 3/4" x 28 threads to avoid this problem, and it's an accuracy issue for sure.

If a brake does not vent in a symmetrical manner that can be a disaster for accuracy (i.e. if it vents left, it must also vent right, if it vents out the top it must also vent out the bottom). I see a lot of brakes that are closed off at the bottom but have vents out the top and I would never recommend these for an accuracy installation.

Robert I would like to talk to you in more detail about your thoughts on brakes and accuracy, I share some of your thoughts but would like to learn more.

I totally agree with this. The high pressure gasses exiting the barrel will affect the bullet as it exits the barrel and goes through the brake. The vent pattern needs to be symmetrical. The same would be true if there is a defect in the crown of a barrel without a brake.
