Minimum force required to ignite the hardest factory small pistol (9mm) primers?
It has been a while since posting on this forum, but I have had an intriguing thought and figured I would ask around and see what I can discover.
I'm not a hand loader, but I'm assuming "small pistol primers" are good for 9mm Luger, and that's what I'm specifically referring to in this question.
To address the problem, there are a few things I am interested in knowing.
First, what are the hardest small pistol primers found on the shelves in factory ammunition (by hardest I mean requiring the most striking force to ignite)? I've always been told CCI.
Second, what is the minimum force required to ignite said primers reliably?
Lastly, how can I calculate the striking force of a firing pin in a Beretta 92FS?
The reason I found this interesting is because I have a Beretta 92FS that I doctored up, so to speak. I put a lighter "D" main spring in (can't recall right away what the actual rating was) and a skeletonized hammer (unsure of the weight at the moment). I have shot a few hundred hand loads with CCI primers through it, and I'm more than confident that light primer strikes will not be an issue.
However, I am mainly interested in the numbers, just out of curiosity. If any engineers or mathmaticians out there wants to explain these questions to me in mathspeak, I would be very grateful.
