Anybody having luck loading cast and powder coated 5.56 for use in an ar15? I enjoy reloading as much as I do shooting so I don't mind the tinkering that comes with making it work in a gas gun. I had a buddy that loaded some just to say he did so I have some data to take into consideration. I have a 55gr. Lee mold coming tomorrow and I have a little bit of lyman #2 in the garage. The lyman book listed 1680 and imr4227 which I keep on hand for my 300blk loads.
