Why did a bell go off in my head telling me something is fishy here? 356 bbl with soft lead 358 bullets sounds correct to me. I would cut my throat before going to lead.
I have all the equipment if you want to buy a bunch of lead wire, bullet formers and those little copper butt caps
I have a very nice .375 Supermag (not a .357 maximum) that my father gave me. He is the original owner. It has only had a handful of rounds through it as he got out of silouhette shooting about the same time he acquired the pistol. It is a blued 8 3/8"bbl.
I have about 150 IHSMA stamped...
