I would have agreed with you guys that it was the gun, but it happened in three different guns all at the same time, maybe we got a bad batch or something, a buddy bought a case for us to use during a day at the range, we experienced really inconsistant failures (i.e. one round would split the hull, the next' s head would separate, the next would shred it' s mouth, the next would misfire, the next would hangfire-it wasn' t consistant for each gun even), it happened in my SxS, a buddies O/U, and another buddies pump-which was more problematic...we ran about a box through and MAYBE got 4rnds that didn' t fail. in fact, those were the only hangfires I' ve ever seen.
