I realize that brakes have made great strides......from what I read, the biggest, and valid reason for the anti radial feeling, is the dirt, debris, it blows up while shooting prone or sitting.....and I agree with that. But, I also used a "tank" brake on a 7SAUM with my son in a blind. The muzzle and the brake were a good ways out of the window. At the shot, I thought the world had ended!!!! The brake directed the blast out of the sides and behind......partially into the blind.... That is why I now use silencers......And believe they ought to be able to be bought over the counter.....rsbhunter
