I've an intermittent problem with rounds not going bang, as they ought to.
Using factory hornady ammunition, out of 24 rounds three did not clickenboomen.
Checked two or three boxes from the same batch and the primers all seem to be uniformly seated and are not proud of the pocket.
When I rechamber the round and try to fire it, just a click and no increased indent on the primer. Rounds before and after this clickenboomen fine.
Could there be an issue with the factory primers being non-uniform hardness? Or just a light striking pin?
I'd have thought if it was the firing pin it would consistently strike light.
