I was resizing some 6mm Rem brass, WW Super cases when I had one that suddenly became tight. I re-lubed the case and when I tried to size it again I bent the decapping shaft and broke the pin. I thought I had messed up so went and ordered a new set of RCBS dies. Thinking back I wondered if flash hole was too small so I tried to push pin on new die thru the flash hole. It would fit 9 cases out of 13. Anyone ever have this before? I am waiting for a return call from Winchester, going to send back the 4 cases.
