LBT 215 FNB .452, sized .452.
For best results, heat treated wheelweights. This is true for shallow Colt rifling as well as polygonal rifling, as the old timers like Elmer used straight lino to "hold the rifling", which means the bullets are hard enough not to lose any side engagement from the lands, which is where the leading starts in most shallow land arms.
It's nice to make a ton of inexpensive bullets, but best results for a ton of cheap bullets don't come from cheap or second rate equipment.
Said another way, I wouldn't cast anything at all if I used LEE moulds or pots. I'd rather watch paint dry or the WNBA....
