I had some of the copper-colored wlr primers that were close in lot number to many of them that were reported.... I hadn't had a problem with any of them and today I had 2 go bad and do it in 5 shots. At least it was just my Marlin 270 bolt action and I got a little burn pit in 2 spots on my bolt face. I probably wouldn't have known anything happened except the second one took out my extractor.
This was a test lot of 5 Winchester shells and I had made a note on the reloading label not to reload the Winchester primers next time cuz they seated ez.... next loading would have been federal primers.
I stopped by my Gunsmith and showed him the extractor pieces and he thinks he can put it back together for me and clean up the boltface. He seemed very aware of the pin holing problem and said the Remington copper primers can do the same thing.... he feels it's related to the loose primer Pockets giving too much expansion at the edge of the cup which is already made poorly with the thin metal. Bottom line is he said you wouldn't have had a problem if these were one or two Fired cases with good tight primer pockets. I've got about 300 of the Winchester primers left and they're going to get buried in my flower garden!
