Gunsmithing Muzzle brake ruins muzzle crown
I'll try to make this short. I added a clamp-on muzzle brake to my RRA heavy bbl varmint gun. Before muzzle brake, rifle shot consistent 1/2 MOA groups. I noticed a gradual reduction in accuracy over the next 500 rounds to where I thought my bbl was wearing out. Bbl cleanliness good through life...- Old Fart 2
