I'll second the reference over to the cast boolits forum at www.castboolits.gunloads.com
. Between the "stickies" and subforums you'll find everything you want to know and more. There's a learning curve to casting and loading/shooting lead boolits but once done it's an addicting hobby and makes shooting a lot cheaper (my .45 cast boolits cost me about $0.02 each). Good luck.
