Damaged 22 Lr casing, was it fired out of battery or a case failure?

[Nick_W]

I was at the range this weekend with a friend. He was shooting my browning buckmark and on the last round of a magazine the gun produced a ton of smoke and failed to eject the round. I come over make sure hes ok and then check out the gun. Upon ejecting the round I immediately notice the hole in the back of the casing and put the gun away.

I called Remington monday and they said its most likely an out of battery firing and to call Browning. Browning said its impossible for that gun to fire out of battery and to call Remington.

Does anyone have any way to tell by looking at the casing whether it was fired out of battery or just a bad round?

From the pics it looks like the rim portion of the cartridge expanded a bit, which leads me to believe out of battery. Lay the case next to a new round and see if the rim portion is thicker on one that is unfired.

How many times did you reload that brass? I've gotten the most reloads by far out of Remington brass for my 5.56 reloads, usually greater than 12 compared to 5 or 6 for Lake City and maybe 8 for Lapua. So I know Remington knows how to make good brass - at least for centerfire.

Hmm. Well, the rim itself ballooned, so the case except for the rim was probably supported, suggesting it was in battery. There is also a clear (and stretched) firing pin mark, so it wasn't set off out-of-battery by debris. I'm assuming it wasn't a slamfire caused by a sticky firing pin, which could create these symptoms, but you'd know because you wouldn't have needed to squeeze the trigger.

I'm going to guess the brass was undersized, and there was just enough tolerance between the brass and the bolt head to allow the brass to flow and fail. Check the pistol bolt to see if the extractor is loose or worn, and make sure the bolt hasn't been battered out of spec, but if not I'm leaning towards it being an ammunition failure.

Third buckmark I've read of this happening (could be rounds or coincidence, but not the only story on the internet).

Happened to me while shooting my 22/45 last year:
