I recently purchased a 454 Lachmiller round ball mold from a member here. I don’t think it was ever used. The mold is stamped 454, but after casting with it this morning I measured a few and they were .445. They fall right to the bottom of the cylinder of my 1858 Remington. Since it’s a steel mold, will beagleing it work to get it to .454? The lead cast was from rolled lead flashing. I cleaned my lead pot out before casting. Any advice would be great. Thanks.
