i fired 2 bare primers today. The first was perfect but the second primer had a real funny, dull/sizzling sound and primer smoke poured out of the stock. Keep in mind, this was just a bare primer!! I opened the rifle and i dont know what the deal was but the primer did something to where it got to messy it splattered my BP grease all over. I think some primers are just a lot weaker than others or something. What ever it was, that second primer was plain bad.
