I get about 6 cycles with Remington Nickel-Plated before the casemouth splits. These are heavily crimped using the Lee FCD. I get about 10 cycles with regular Starline brass. But I'm only loading full-up loads for a S&W329pd now, and I can't get away with mild crimps.I realize not all pieces of brass are of equal length and weight, but I'm just curious what the consensus is here for 44 Mag brass life when loaded at or near full power?
