Robinhood I do agree they look pierced. But that is what is so puzzling I have loaded that same load in the past without these problems.

The 6 on the left the book load range was 33.4 - 35.2c and was charged with 34.5 H4350 and set .005 off lands.
The 6 on the right the book load range was 29.2 - 31.8 and was charged with 29.5 Varget and set .010 off lands.
Both with CCI 400 primers and Sierra 107gr HPBT MK and Norma Brass.
Notice the 6 on the left was only 1.1gr over minimum and the 6 on the right was .3 over minimum.
I'm wondering if the pierced problem is the CCI Primers? Can't find my data but I do think I was using the CCI BR4 primers before but not sure.
I still don't know what caused the firing pin to not strike the primers again, I did a real good cleaning and did not add any grease or oil on the bolt before this outing....

Back off on your load or look at the firing pin to hole clearance
Are you referring to the firing pin protrusion? If so I did and it measured .52.

Thanks all for the input!
