I cast a 390 grain bullet for my 1895 Marlin. Biggest cause of leading is not velocity but the bullet being a correct fit for the barrel. Mine slugs out .458.2. My mold cast a.461 bullet that I size to .459. Around 1100-1200 fps I don't need the gas check but I'm running around 1500 fps and prefer the gas check in either situation to prevent blow by of gasses. I get practically no leading. After 50-60 rounds at the range a bore snake with a little clp ran through about 3 times and it's clean. 45-70 a very old cartridge that is here to stay. I do water quench mine and the ones I have air cooled are around 18 BHN verses the water quenched being around 23-24 BHN.
