I've accumulated a bunch of LC-69 CMP brass and recently decided to try my hand at reloading some for my Garand. I'm using an RCBS FL die in a single stage Lee press. It seems to be taking a huge amount of pressure, and even then, I can't pop the old primer out. I tried it on several cases. Is this normal? I never had any problems with the same setup working on Remington commercial brass. Thanks!
