I'm not planning on casting my own bullets just yet. I've been emailing the guy that runs hotshotbullets.com, and for now I'm just going to order some from him. Both of my 1911s are newer guns, one Rock Island Armory and one Springfield mil-spec. The Rock Island will shoot anything I feed it, but the Springer is still not broken in and will only feed FMJs. I want to order some semi-wadcutters, but I'm afraid that they won't feed properly in both guns just yet. He also sells some lead round nose bullets, so that's probably what I'm going to start with.
