I’ve convinced myself that this is the most likely of the two scenarios, but I’ll describe the other scenario (bullet setback) as well. If you compare the photo at the end of the above video to the case stuck in my chamber, they are identical. His burst cartridge case sure looks a lot like mine.

He caught it on video and posted it with a photo of the case.

I did a Google search on double-charged cartridges, and what do you know, there’s actually someone out there who did the same thing I did. Compare this to the photo of the double-charged case at the end of the video below. It was a Remington case, not that it makes any difference.

I’m down to thinking the 1911 event was due to either of two causes: A double propellant charge, or bullet setback (i.e., the bullet slid deeply into the case as the round was being chambered, thereby raising the chamber pressure).

Rework of the ammo I had loaded on my Lee turret press.

This is an update on my 9mm 1911 sudden unintended disassembly saga.
