I've been thinking about buying some stuff to do my own casting. Well, my father in law told me yesterday that he has everything needed to cast except lead and moulds for ML's. Right now, I can really only afford one mould, but don't know if I would be better to find something that would work better with a sabot, or a conical mould. I have a KRB, and while I've not shot conicals out of it yet, it sounds like it's a great conical shooter. So, what would be the best investment?
