Slamfire, are those cases in your pics leaking AROUND the primers or poping a pinhole in them.
Yes, and I culled the pierced primer rounds. A number of these rounds the pocket had enlarged to the point the primer fell out.

I do see leaking primers as a sign of too high pressures, but also that other things can(though less likely,yes) that may cause the same indicator, but not be above spec
The probablity of a defective cup or case is much smaller than the probability of a leak caused by excessive pressure.

But, no pictures of this guy's cases, so my best guess is high pressure.
