Just ordered Lee 45acp carbide dies, a final replacement decapping rod for the RCBS die (power punch-style, see if this works better), and 500 starline 45acp + p brass.
I will retire my current brass and just keep the RCBS dies as a backup set. I have dupes of almost all my dies now as I have learned I like Lee dies better than RCBS as a rule. Heck, at $20 to change to Lee, it ain't that big of a deal.
Honestly, after finally discovering the off-center flash holes in the PMC brass, I am pretty well convinced that is the source of my broken pins and bent decapping rods. Eliminating the questionable brass will probably solve all my problems, but I really find that I just like the Lee dies better.
