I have a question....a gent I know casts for a Gibbs muzzleloader often and has said I can get some bullets from him. They are of course grease grooved, but are close enough to to be sized down if the .446 bullets work. Will the grooves effect the patches? Could they be used well enough for hunting? I am not, not ever will be a competitive shooter, and am much more a hunter, plinker, bit if they will work and I can get them inexpensively enough why not gopher it?
