Ive just been trying to set up a RCBS f/l sizer die. Now I wasnt getting the shoulders back far enough on the once fired brass I was given. So I screwed the decapper pin up and carefully and slowly turned the die in little bits at a time to get the result I was looking for. Once I was happy with the size I screwed the decapper down till I felt it touch the primer lowered the ram and gave the deccaper a little turn lower raised the ram and snap decapper pin gone... The primer hadnt even been popped or even looked as if the pin had started to push it out. Now is it possible to buy spare pins and who has them. Also any tips on stopping this from happening again.
