Thanks all. I,ll try to post some photos. As per advice, I,ll switch brands, have some Noble sports, and work through the process of elimination. It seemed to happen more frequently on the left barrel, again randomly, and the depression on those not pierced was no deeper than the right. The gun is a Scottish James Crockart, Blairgowrie, box lock. Never did this before and the unpierced eject just fine. I only use WW 209s. Had some lite strikes with an LC 16, but never anything like this. A few penetrated well into the primer so I could see the anvil. They were from an old sleeve, production run, and were reloaded AAs old style, 3/4, 700x, in 2015. Would excessive pressure seating the primer during the reloading process have an affect? I sometimes push hard on the seating with the Mec 600.
thanks again
