Went to the range today and shot some C&R rifles. Had a fine time.

My shooting buddy, Vern, noticed a piece of brass and picked it up and showed it to me, and said, "What is this?"

I had a couple of guesses, but didn't know for sure.

Want to try?

It appears to be a round of .30 Carbine brass. I was not shooting a .30 Carbine, so it wasn't one of mine.

Here it is.

It is the one on the right, with another round on the left for comparison.

Here's another view of the blown primer.

And another view of the two rounds.

That's all the information we have. Don't know what firearm. Don't know if they were reloads.

Before I tell what I think happened, anyone want to take a guess.

Someone tried to shoot it in a 30-30?

Someone forget to neck down some reload brass?

((ETA)) Or, forget to reset the reloading press when changing ammo?

((Yes...I'm throwing WAGs out there...haven't reloaded since I was a kid helpin' dad.))

Someone gave me a plastic ammo box full of rounds like that. They are all loaded and have that bulge in them. If I can find them later I will post a pic, not even sure why I kept them, no one knows why they are like that and still loaded.

Is the non-deformed brass from the same range? It appears to be developing some odd marks in the same place as the bulge. Possibly reloaded brass at the end of its life or OOB? I'm not too familiar with .30carbine.

Yup, but the brass held against the pressure, hence the deformation.

I've seen the same thing out of a .22 semi-auto, I think a Mossberg or a Marlin. The rifle had a tendency to eat sears, and occasionally it would let off a magazine in full-auto. Very unnerving. Brass looked the same as it does here, a result of discharging out of battery.

ETA: It isn't necessarily firing out of battery. It could be cycling too fast as well, and ejecting brass before pressure reduces enough to be safe.

The case on the left was fired in the gun it was supposed to be fire in, the case on the left...wasn't.

I dunno... it's almost like it was fired in a revolver designed for a different (but similar) cartridge.

Weird.

My M1 Carbines won't fire if they're out of battery even a fraction of a inch. The only other .30 Carbine gun I'm aware of is a Ruger revolver.
ETA: Ok, firing pin stuck forward on an M1, fired as the round chambered. That's the only way I can figure.

That's my best guess.

Or over-pressure with a slightly unsupported chamber.

Right, well I meant to say right instead of left...wait that's not right either...

I'll just say it this way: the left case was fired in the proper gun and the right case wasn't.

Years ago, when I was learning to reload, I was reloading some .308 and had the bullet seating die adjusted waaaaayyyy too far down. The finished round had a bulge around the base just like the case on the right. I learned how to use a bullet puller that day.

ETA: But, of course, those rounds would never have chambered, so firing out of battery is my guess as well.

AMT made an Automag in .30 carbine too- hellaciously loud and pumpkin sized fireball.

While I find it hard to believe an M1 carbine fired that far out of battery, it's the only answer I can come up with. Wow, that's a long way out of battery. And there's no way this came out of the Ruger revolver. It almost looks like a case resizing problem, but it would never have chambered, much less fired and it has none of the marks down the case I would expect to see if a sizing die did it. I just can't picture a gun with a similar sized cartridge that would hold it with just that much case exposed, and successfully fire it without blowing out the case. As much as I don't like it, it must have been an OOB fire in an M1.

Picking up brass last weekend, found a 7.62x25 round just like that one. A lot of other(7.62x25) brass in same location but only one like it.

"LC 52" marked .30 carbine? Probably corrosive Chinese crap. That garbage will destroy carbines.

My thoughts too.

And yes it most definitely fired out of battery. Ammo could have beem a contributing factor.

Kimball pistol is another potential candidate. Kind of scarce, but they were a fluted chamber, blowback pistol. Looked like a big Hi-Standard auto.

Having worked in a gun store and seeing all types of people, I will say this...

Just becuase it is a .30 Carbine cartridge don't assume it was fired out of a gun chambered for the .30 Carb. We get a lot of people who seem to think ammo is interchangeable, like the old man that could not understand why the .38 Super would not work in his .357 S&W.

That case taper looks like it was fired in something else...

someone didn't crimp their reloads?

Loaded up a mag. Started firing round in the mag had some OAL issues. My guess. Then again, I may not feed properly because of OAL issues so I'll just go with OOB firing.

Universal m1 carbines are notorious for firing out of battery.

This.

...and it looks like it might have had a bit more powder than necessary.

It could also be that being fired out of battery may have helped deform the base, making it it LOOK like the primer deformed as well.

Universal made a batch of M1 style carbines that were prone to fire out of battery. Enough so that they would crack the charging handle.

These are the carbines with the two spring design.

Yeah yeah beat by mere seconds..

The primer doesn't look flattened so probably not a pressure issue. I wonder if someone tried to shoot it in a 30-06 or 308.

I'm guessing out of battery as well.

That's way to uniform to be an out of battery firing. I'd expect it to pop before being that precise. Looks to me like it was fired in a rifle chambered for a belted cartridge, and it fireformed to the belt. I have no idea what belted cartridge would have a base that small though as generally they are thick. Maybe it was fired in an old oddball British chambering...

I honestly can't think of any other cartridge chamber that would allow a .30 Carbine to be fired and work.

I've actually got one of the 2 spring universals in question. I should check to see if there's a counterbore in the chamber to account for the front edges of the bolt. If it's there, that could be the reason for the precise buldges.

I have a Spike's Tactical .22 conversion kit that has fired OOB and produced .22 LR cases exactly like that.

I had a M1 carbine that did just that, case looked just like that but it ruptured on the top, felt like somebody slapped me on the forehead. I still have the case and the bolt group somewhere, if I find it I'll post a pic.

In my .30 Carbine reloading experience, an M1 Carbine will not fire even if is a little bit long, in fact .30 carbine is the most length sensetive caliber I have ever dealt with. I highly doubt it was fired in an M1 Carbine. Looks like someone fired it out of a Nagant revolver.

ETA: Did not know about the Universals known for OOB issues.
