Re: Muzzle brake clearance screw-up.
.020 is the absolute min as far as I am concerned. and a lot of people like.030 so I don't think
.040 will make that much difference.
Obviously the more you open it up the more it will reduce the effectiveness of the break. But not
by much as Alf and Judd said.
I have seen breaks with the barrel tenon diameter all the way through the break and they still
worked (Al tho not as effective as other breaks with "correct" size bores).
The main thing is that it is concentric to the bore.
