On the very first stage of last Sunday's C&R 2 gun match at AGC, Katie's M1 carbine jammed closed on about the third round. She couldn't force it open, so after a few wasted seconds, she safely abandoned it in the dump box and, took a bunch of FTE's and went to work with her pistol. When it was time to clear the rifle, I snatched the bolt open and was rewarded with a (much larger and more widespread than expected) shower of unburned powder. I took it over to the safe table and tapped out the bullet that was just barely held by the rifling. Fortunately, I had taken a pretty good mental picture of where the offending casing went and was able to find it. In addition to the fact that there were not many pieces of .30 carbine brass laying around, it was pretty obvious which one was the culprit:

These were factory (Arsmscor) rounds that the rifle had previously really liked, in both reliability and accuracy?
What happened?
There is another pic that clearly illustrates the problem. It would be fun to take guesses and build suspense and tease every one (because it's something I've never seen and never would have guessed). I'll put that pic as the first comment, so you can speculate without seeing the punchline:
