I have this mold and it cast .475 RB's. Pure lead, clean hot mold, hot lead and BPSL used on all surfaces of the mold. This mold came in a package deal and along with a .595 Lyman mold has me stumped as to what to use the .475 for.
Does one use extra thick patches for 50 Cal ML?
Could it be used for round ball loads in a 475 Linebaugh?
