I am a newbie, I have the Lyman Cast book ordered so while I am waiting I thought I would gather tools & equipment. I have a question about molds. Should I buy a 2 cavity first, sort thru the standard newbie problems and get use to making good boolits before moving up to the 6 cavity or jump all in with the 6 cavity? Is the 6 cavity more difficult to master than the 2 cavity?
