I load my own cast 405 grain bullets in two 45-70's -- a Buffalo Classic with a 32" bbl, and a Marlin 1895. The powder I use is AA5744 -- 25 grains. Accuracy is phenominal. I water quench the bullets out of the mould, and tumble lube them. Velocity is 1250 to 1300 depending on the rifle, and NO problems with leading the bores. My mould is a Lee single cavity el cheapo that just keeps tossing out 0.459 bullets.
