Has any one heard of or know a sourse for a bullet mold .454 Dia. 405 GR SWCGC been trying to find one for a buddy.

Probably not going to be easy, it is a pistol diameter but rifle wieght. A rifle diameter bullet could be sized down easily in a Lee size die, without distorting it , due to the nose first alignment, and might work just fine. Also lee moulds are known for being undersized, and might drop a bullet just the size you need. Now for the big question, what are you going to use this in, and/or for? DM
