I have come upon a quantity of Fiocchi brass huls, 12, 16, 20 and 410. The 12's and 16's require an Alcan G57F primer, the 20's and 410's are Berdan. I understand thet Berdan primers are available, somewhat, but what do you use as a replacement for the G57F's? It is my understanding that a 209 primer is too small (diameter) to be retained in the hull, anyone have any ideas? I would like to sell these, and will post them in S&S if there is a way to prime them without reinventing the wheel!
