.357 Mag Critical Defense Overcharged?

Did some shooting today, including the .357 Mag Critical Defense I use as my defense round in my SP101. Something was wrong with one of the rounds. The shot itself didn't seem off, but the revolver wouldn't cycle for the next shot. Investigation showed that the primer had blown completely out of the round and was stopping the cylinder from turning. The primer pocket was blown all the way through. The case was also expanded so much that the rounds would not extract by hand. I had to use the bench and press down with my weight to extract the rounds. It was really tight.

Has anybody experienced problems with this ammo? It was factory fresh, not reloaded, but acted like a double-charged reload.

Just a quick update:

I emailed Hornady and they asked me to call. They set up a return and are sending two boxes of ammo to replace the questionable one.

I'm pleased.

Final update:

Got a call from the testing tech yesterday. No problems with the loads, so they sent the brass up to be tested. It was softer than it is supposed to be.

They're sending me a replacement box of .357 and .38+P (different lot, obviously).

Good service overall.

Sounds like an overcharged shell. Soft case metal wouldn't really cause the hard extraction.

Luckily, with magnum cases and powder, it's hard to overcharge it to the point of catastrophic explosion because the case can only hold so much slow burning powder, even with a compressed load. Not saying it can't go overpressure, but there is a bit more wiggle room.

I had one Hornady factory round of 357 Sig chronograph at 1800 fps! It felt like it too. If a round is so stuck in the cylinder that the ejector jams, it might be best to use a rod through the front of the cylinder to prevent from damaging the ejector.
