Any chance there are Remington 9.5 primers?
I've run into WW brass with shallow pockets caused by an overly large radius in the transition between pocket sides and bottom. I've also run into a batch of 9.5's that were on the tall side of specification. Combine those and voila!
Large rifle pockets should be between .128" and .132" deep. When I cut pockets to .132" that batch of 9.5's still needed a strong seating stroke to get them flush.
