Ok, Skinny, you sound like you know what you're talking about. How confident are we in the purity of "pure" scrap lead? I have a stash of old toilet elbows and roof flashings, but have no way of knowing how pure it is. I am putting together a kit for a muzzle loading slug gun, and consistency is totally the name of the game. I have no problem using scrap, and likely have no problem sourcing it, but I am pretty sure I am in for lots of ass-ache if I can't come up with consistent alloy. I have considered a hardness tester, but thought I'd opt for the sure thing to start with. Oh, here's a question...how pure is the lead in lead/acid batteries?
