Burned two pits (slow learner)in a model 70 bolt face with WLR primers a couple years ago. 2 rounds in a hundred or so primers that I know of(DFL722 G). They were the best performing primer with one powder combination.
I had decapped and saved primers from three rounds and saved them for some reason. Had quit using the WLR primers but often tempted to try another 2 lots I had.
As a result of this thread I called winchester. Emailed a photo of bolt face and primer with pinhole and cracked side.
Sounds like they want the fired primers. Asked if I had Any Loaded cartridges. It also sounds like they want all three lots back.
