Reverse Glocked brass.

Here is an interesting one. I think they were fired in 40sw.

It sure looks like it...did you put a micrometer on it?

[BigAlofPa.]

No but i put them mouth to mouth with a 40 casing.

[Neverhome]

Interesting! What’s the backstory?

[BigAlofPa.]

Just found them on my brass round up. There were shooting 40sw too. I'll put them with my strange findings.

[dragon813gt]

That’s what happens when you shoot 9mm out of a 40 S&W gun. They go bang but don’t eject. Don’t ask me how I know.

Well, that blows that "Head Space on the Case Mouth" argument plumb outta the water, don't it?

Not really. It just means the extractor is long enough to hold the case secure enough to fire.

It fairly common for the 10mm crowd to shoot 40 S&W in their guns

Same thing, 40sw in a 1911!
At the range had my Guns laid out, about two foot between the Guns with the right ammo! One of my friend's comes up to me and says the gun 'jammed'! Drop the magazine, racking the slide hard, out comes a 40sw case bulged out to 45ACP! "I fired twice, second one didn't eject,' he says. Looking at the magazine he had filled the mag with 40sw!!! He never shot any more of my weapons. I was glad that it didn't hurt him or my 1911! No sense in explaining what could have happened to him he was clue less.

I found a couple of9mm that looked just like that and determined that they were fired in a 40 (I had a 40 cal. bullet on my bench). They make an interesting knick knack.

Exactly my point!
That "long extractor" has saved a lot of idiots from damaging a lot of guns.
Seems to work most every time. Kinda like the cartridge head spaces on the extractor, not on the case mouth.

I first saw that on a commercial range that rented guns. Somehow the counter guy rented a forty Ruger and sold the customer 9 parabellum ammo. A minute later I saw him flying into to range to stop the customer but he'd already started shooting, and was staring at the funny looking keyhole hits on his target. I found a few of those cases on the floor behind his shooting lane.

[justashooter]

my son loaded one round of 223 in the middle of a mag of 7.62X39. it self-loaded and fired but did not extract/eject, and had filled the chamber. like this. he did the same thing with 32 ACP in a tokarev, with same result.

he was 10, or so.

[KCSO]

You sure those aren't 38-40? I can't believe they ever fired at all!

[jimlj]

When I saw the pictures the 10 year old in me thought "cool, I ought to try that in my Glock 23", but the 62 year old in me said "Do you value your face, eyes and fingers?"
The age and maturity in me barely won the argument.

Does it work? Yes, as you pointed out most of the time it does. Is it less than ideal yes. The same can be done some bottleneck higher pressures bottleneck cartridges is some actions/chambers. With straight wall lower pressure cartridges the same headspace issues exist but due to the lower pressure the the problems are minimized. As to saving idiots from damaging guns using the extractor to hold the case most likely induces excessive headspace. In the example of 40 S&W fired in 10mm chambers if the extractor wasn't holding the case it mostly likely would not fire. On bottleneck cartridges like the 30/06 even something as short as a 6mm BR will fire if even without an extractor since the case will only go so deep into the taper of the chamber.

My one and only accidental firing of the wrong cartridge is the wrong chamber was five 6mm BR's in a 6mm XC chamber. I was doing some match load development on to identical rifles (except for the chambering). Both Tikka 595's Master Sporters. I had just re-barreled them wanted to see if I had any barrel walking issues. Five shots in rapid fire cadence. When I reached for the 2nd mag I noticed the brass was very odd. 6mm BR in a 6mm XC chamber will blow the case straight except for a small portion that does in the 6mm XC shoulder. They did shoot to the same POI and groups was not much larger than with the correct ammo a 200 yards.

[BigAlofPa.]

They are 9mm. I checked when i found them.

[country gent]

I have found 308/7.62 on ranges with no shoulder or neck left fired in a 30-06 chamber 1 time was at home club member had a garand with insert in it that pulled out on extraction. 2nd was at a leg match older gentleman was issued 308 from the ammo truck for his garand. ( Im showing may age now issue ammo at a leg match).
Ive also seen the above 40 sw in a 45 and 9mm in a 40

[SOFMatchstaff]

Those cases look to be from the rare Burnside pistol, yeah thats it....

[quack1]

I've found a few "fireformed wildcats" when scrounging brass at the range.
7mm express fired in 7mm mag, 40 in a 45, 41 in a 44, 32 auto in a 380 or 9mm, 9mm that blew out over an unsupported feed ramp or fired out of battery and a 9mm that fired out of battery.

I took a good friend to the range for some plinking one day. There were two Handi rifles along. One in 357 and one in 30-30. Yep, he fired a 357 in the 30-30. Surprisingly the lead bullet swaged down enough to exit the bore and the case split like the ones pictured above. I've quit being concerned if cast bullets are a bit larger than the bore slugs if they chamber with a couple thousandths clearance Gp

You've just discovered the latest invention - instead of "bottle neck" casings you found the new "funnel mouth" cartridge case.

I have a feeling that such things happen more often than folks will admit. Mainly by those who don't take the time to pay attention to what they are doing or are distracted - which means that maybe they shouldn't be shooting those days. A few years ago, I was at a range with a friend of mine shooting pistols. H's no "slouch" - retired AF, very mechanical and a former flight engineer. His wife was with us and she had a Sig .380 she was firing - her personal pistol. My friend was firing his Springfield 9mm. Evidently, he and his wife switched handguns for a few magazines. All of a sudden, he came over to my shooting slot and said he was having problems. He had fired three rounds but all of them had to be hand ejected. I took a look and yep, he had mixed .380s in with 9mm. Fortunately, no one got hurt and no damage was done to his pistol - that was my first personal experience with "head spacing on the ejector".

[Mal Paso]

This thread explains the 308 in the right photo. The straight walled version was fired in a 308 Norma Magnum Browning Rifle. It must have been held in place by the extractor.

[BP Dave]

Years ago during I was at pre-season sight-in days before fall hunting at a range in the upper Midwest. One poor fellow was obviously annoyed, because he could not get any accuracy out of his sporterized Mauser. The fired cases looked odd, and I asked him a few times if he was sure he had the right ammo--he became quite testy in his replies, assuring me that he knew his rifle was chambered for "Mauser." Turns out 7x57 ammo is not all that accurate when fired in an 8x57 rifle. I recommended he get the "next larger size" for his rifle--I hope he listened.

This is kind of amusing.
He is evidently enough of a "slouch" that he had to come to you to figure out what was wrong.
