When I checked the rest of the rounds from the batch I had brought with me there was almost no crimp, or neck tension. As the round fed the bullet was pushed back in the case driving the pressure up. I ended up taking the whole lot home and running them through a Factory Crimp die. I had to chuckle at the irony of running factory ammo through a factory crimp die. You can't check every round though, so having some type of tool handy is always a good plan - that type of stoppage can be a pain to clear.

Primers are usually the first component of an overpressure round to fail and they may flatten and flow, pierce or blow, depending on the circumstances. Take the overpressure further and you see case head failures; further than that and you see barrels/chambers coming apart in catastrophic failures. David,
