Just for FYI, the brake was a JP Recoil Eliminator (Tank Brake).
Bart, the brake can't be the problem because the rifle shoot well with and without the brake. It only goes screwy for the first two shot "after" the brake is "removed".
Brian and mapsjanhere, I'm only firing 5 to 10 shot strings before removing the brake but crud on the muzzle is something for me to check. Thanks!
mapsjanhere, the muzzles is exposed inside the threaded section of the brake. The brake has a 5/8" threaded hole for the barrel to thread into. Muzzle falls about 1/4" or so short of exiting the threads into the brake's first chamber which is where JP recommends.
Guns are not dangerous! People are! RKBA!
