I bought a Marlin 44/40. Slugged the barrel with a 427 and got good engraving from the lands none from the grooves. Bought some 429 bp lubed bullets and then tried to load one with resized brass. Got it done but not very good. I have a universal expansion die but its only good for the very top of the brass. So I tried some brass that had been shot in my 66 and cleaned. No neck tension at all but would chamber alright. Next took some brass shot in my Rugers, used the expansion die and the bullets were a nice snug fit that could be pushed with my fingers down onto the powder with a little effort. Chambers nicely and later today I will see how they shoot.
I tried some hardcast factory loads in the rifle earlier that I do not know what size the bullets were and it was very accurate at 50 yds.
