Thanks for the replies. I have attached a pic of the breach face and the fired cases as requested. The case on the left has a small pin hole in the primer the one on the right is ok. As I mentioned very few have the pin hole, maybe 5-6 out of a box of 50. My macro photograpy is not that great.
Here's the breach face. Firing pin protrudes .055".
The tip of the pin looks to have a slight "tit" on it when viewed on a 20X jewelers loupe
