I had similar experience with a flat of Rem GC 12 gauge hulls. They were all my own once fired hulls, and when inserted into first de-priming station, they would actually bow out the base until finally popping the primer out. lost quite a few hulls as they wont sit flat anymore..
My same guns firing all the shells, same press I used on all my shells. MEC 600.. No issues since that flat. I dunno..
