I had Dave down at Daves guns thread the end of the BBl on my 300 RUM and screw on a break.
The break really tames the recoil but the muzzle blast kicks up crap off the ground when I shoot prone.

Dave does a nice job, they look like a permanent part of the BBl. I've got to get a thread protector for this rifle to use when the break is off. If you unscrew a break and shoot a rifle without it, after awhile the threaded part of the BBl will expand, the metal is pretty thin in the groves of the threads.
