I figured this is the place to get help and advice casting lead bullets. I have a shooting buddy with a DE in 50 ae. He brought me an RCBS mould and LEE dies for 50 ae. The mould drops bullets at 365gr and .503 diameter. I went online to look for load data, none in my manuals, and everybody, everywhere says don't use lead in a DE or any gas operated gun. Can I use load these monsters in S&W 500 cases? Are there wheel guns that shoot this cal? I'd sure appreciate advice.
