AHHHHH, I thought I was alone! My fix was to back the seating die out from the toolhead....like way farther than you think. It only happened occasionally on some pieces that had stretched just a little longer than the rest and slipped by in prep. There is a shoulder up in there somewhere that catches the case rim and was bulging my freshly reformed Grendel brass. At first I though it was a case of over annealing since it was immediately following my first run of it. The fact that it was sporadic made me look closer.
If you load very short projectiles make sure you leave enough on the micrometer if using one. I have loaded Berger 95 and 105 VLD so far but don't have anything smaller to try. Try that and I hope it helps.
