PUNCHING HOLES IN THE PRIMER

[nod 285]

went out to check my zero, first 2 shots were fine then open a new box of norma in .223 and fired, smoke came from the bolt there was also a loud bang from the bolt and it has put 3 tiny little holes in the primer, what has caused this ? could it be the firing pin sticking out too far?

got a pic of the primer?

May be faulty primers in the Norma bullets if the first two shots were ok before using the new box, try another brand and see if the same happens, if not it's the Norma primers, if it still happens looks like it's the firing pin.

I'm just thinking aloud here, I have no idea, could it be that the firing pin spring is quite strong and the pin punched through a thin bath of peimers, the priming compond went off, pushed the pin back, the pin goes forward again the the main charge then pushes the pin back a second time, each time the pin punches a hole in the primer?

 

probably not, but as others have said I 'll bet it's the primers..... Norma are usuaklly a very good brand....
