Going to put a Harrell Tactical (4- port baffle style) brake on my 45 cal smokeless mz, and I was wondering if anyone could give me some feedback on what would be the minimum diameter that would still be effective. The barrel finishes @ .830" at the muzzle. So, ideally, I would like to match that, but will go bigger if I have to. Obviously, the bigger the better, but is there a good rule of thumb for minimum diameter without really causing performance to fall off? Thanks!
