I just bought a used ULA in 22-250 with a Varmint Brake (no holes on bottom) installed by High Performance Gun Smithing. The brake is effective, but I am not willing to sacrafice accuracy. I am starting to test loads with and without the brake, but this doubles my load development efforts and I have not yet come to any cnclusions. I am also considering installing a brake on my .243AI.
I am interested in your respective experiences regarding muzzle brakes
and accuracy. Thanks, Robert
