I'm fairly sure the of the answer to this, but I'll ask anyway. Are steel core, or AP bullets as components available? If they are is it illegal to manufacture rounds from them? Alternately would it be feasible to design a mold for a 7.62 mm bullet intended to be used in the pistol round that was pointed and cast it in hard lead or copper? I am completely ignorant of everything having to do with hand loading so these ideas may be in left field. 800 rounds from trained LE, most of them aimed at the head, all were ineffective, scary. I would assume that they would be better than I am in a shoot out. Maybe practicing praying under pressure as well as marksmanship would be a good idea.
