Who was the effin d bag that decided they would save .50 cent per billion rounds to use small pistol primers in 45 acp.. Nothing will kill a good run on the progressive press than a small primer case slipping through. Seems every time I get back in a good rhythm I get another. I have looked through most of the cases before they hit the case feeder but I guess my eyes suck bad enough I can always tell em apart Ok I'm done ,, just had to vent !!
