When I first started reloading for the AR, I used Winchester Small Rifle primers, which sporadically pierced, pitting the firing pin in the process. I "solved" this issue by switching to CCI BR4 primers (I haven't run out yet since last year) but I'd like to reopen the discussion because the subject is interesting to me.
When I reported that I was getting pierced primers on my AR with the Winchester Small Rifle primer, I received many answers ranging from that primer type having too thin of a cup to my rifle's headspace being an issue. The CCI BR4 primer has completely solved the problem, however it would be nice to get a conclusive answer as to why this happened with the Winchester primers.
The other step I took was to measure my firing pin protrusion, which was within spec. I also replaced the pitted pin.
I posted about this issue originally over a year ago. Is anyone around now who has "solved" it through means other than switching primers?
