By the time you have that lee bullet reground, assuming they don't screw it up, you'll have the a good bit of money tied up in a set of aluminum blocks that are to soft to last long , and handles that are to flimsy to cast that big of bullet to start with. Better off to just go with a proven bullet like the Lyman Postel, or the RCBS 820284 or the Saeco 645.
I gotta kinda go with Ranch on that one. All my best moulds were made of cast iron {Lyman} and will outlast me.
