I just picked up a Marlin 1895 model with 18" bbl and porting and had a couple questions for all you 450 reloading afficianados. I'm looking at hot loading 400 +/- grain hardcast gas checked lead bullets in this gun. I'll be molding my own bullets. Can anyone suggest good powder/s for this bullet weight and also a 400 +/- grain bullet mold which produces accurate bullets.
45-70 loaders are welcome to chip in.
Thanks.
