So i just started reloading this year in general and started with the 45-70. I have sussefully reloaded several diffrent loads. But I alway start out by crushing a case or two. When trying to seat a bullet. Starting to piss me off and I am not sure why it's doing it. Dosent matter new brass or fired brass still happens. Trim to length, I full length size all the brass, I expand the case to where it just fits in the seating die. I have the bullet seating die all the way up and it still crushes a case. Any advice
