I have frequently found that even with much thicker barrels, if the brake is put on too tight it will measurably constrict the barrel. Again accuracy rarely suffers from this effect.
Cutting a crown .600" deep before where a brakes baffles begin would make for a very weird installation. I like the end of the muzzle to end exactly where the port starts and taper back at 11 degrees to the crown.
I have never seen any loss or gain in barrel/bore diameter doing it the same way as Hired Gun, so ether I have been lucky or just picked the right way to install a brake.
If you have a good class 1 thread fit I can see no down side.
Like many others I subscribe to the "KISS" method (Keep it simple stupid) and don,t over complicate
things and concern my self with the quality of work and components.
