my rifle will keep three shots in under 2"(heavy loads) and i use leupold scopes. i like heavy bullets and lit,gun powder, be sure to get bullets that have heavy jackets as at the speeds you can shoot with the .460 the thin jacketed pistol bullets just go the pieces(explode) with no penatration. i just bought a .475 linebaugh in a ruger #1, but have not shot it yet.
