None of my magnums sees jacketed bullets, not since about 1980. I use lead bullets & recently coated lead. Nothing a good lead or coated lead bullet can't do vs jacketed & with less wear on the forcing cone. I used to shoot about 5K full power 44mags a year in met sil, jacketed plays havoc on a bbl forcing cone.
There are many cast/coated bullet makers now, both powder coated & Hi-Tek epoxy coated. Badman, Bayou, SNS, MBC, Cheycast, Acme, the list is pretty long. Plus it is stupid simple to do yourself if you cast your own.
