My 38 Special sizing die is not always de-priming the brass, whereas it used to not have this problem. and I can't figure out why. Here is my setup and the last thing I changed:
RCBS Pro-2000 Progressive Press - 3 years old.
Station 1: Sizing die: Lee
Station 2: Expander die: RCBS
Station 3: Powder drop
Station 4: RCBS Lockout Die (powder checker)
Station 5: Lee seating and crimping die
Brass: Winchester, the cases have been reloaded for ~2 years now.
Primer: CCI
Last thing changed: I've begun loading cast lead 158 grain SWC. I used to always load plated or FMJ with this setup and never saw this problem. I am doing a roll crimp into the crimp grove on the lead bullet rather than the taper crimp I was doing with the plated bullets.
What I've tried: I put in a Dillon sizing die, and it fails to de-prime 50% of the cases whereas the lee was only failing about 10% of the time.
All of the dies seem to be installed correctly. The only change to the dies that I made was to the sizing die so that it would seat the new profile bullet and roll crimp and to the expander die to expand the case mouth a little more for the lead bullets. I don't see any interference when the shell plate comes up. The sizing die base sits just a hair above the shell plate when the ram is down.
Any suggestions or help would be greatly appreciated. Thank you.
