Before you ask why on Earth would I want to make this just hear me out. I'm looking for help and or advice on how I'd cast some projects, .45ACP, out of bullion silver. I've done a little research and realize I'd need an iron mold because aluminum has a lower melting point than silver. My goal is to actually load some rounds that'll really fire, not that I would shoot them. Let's just say this could end up being a gift for someone who has everything. Any advice or help with some equipment use would be awesome. And yeah I seriously want to make probably about 10 of these or so.
