powder for me. I was blasting some 350 gr. .375 RNGC out of the .378 GNR at near full power with no leading. The long cast RN riveted badly and tumbled in my backstop media but the speed was there.
In .416 Rigby I have done good work using the surplus .50 BMG powders and magnum primers. I have a 325 gr. and 375 gr. mould for it. I did it in .458 Win. too but seated long way into the throat like a .458 Lott to get enough powder capacity. The stuff burns like a candle!
