I am considering muzzle break for my .300wm. The gunsmith claims that alone will get my Sendero from 2" at 300 yds to 1.5 or less. He actually claimed down to 1" at 300 yds. I am not an engineer, gunsmith and not much more than a novice at LR Shooting. I know the benefits and am sold on the MB, but wanted to get some input on accuracy benefits minus the flinch factor. Any thoughts or stories /ubbthreads/images/graemlins/smile.gif???
