New to bullet making. I have an original 1873 Trapdoor Springfield rifle that I reload with black powder. I was given about 150 .459 405 grain bullets that shot quite well; however I have run out now. I bought a Lee .459 hollow base bullet mold. Im having trouble finding any lead to melting. I have access to wheel weights but don't know how to remove the steel parts. So I was wondering if bird shot can be melted down as a easy to find source. Sorry I guess thats a double question.
