found this little gym at the range

[justing]

found a couple of these at a range a while back and was looking for what y'all think.651876518865189

[M-Tecs]

OK, I give. I don't have clue as to what I am looking at.

[justing]

its a 9mm luger round that went wrong

[justing]

don't know why or how but it went wrong

[ncbearman]

Maybe a mistake from a 310 hand loader.

[justing]

its berndan primed so i don't know if it a reload

[Rangefinder]

Looks like something that slam-fired out of battery but didn't rupture. Odd... Must be some soft brass to expand like that without splitting wide open.

[Chicken Thief]

Steel case?
Fired in a submashine gun that poofed out of battery?

[x101airborne]

I been to two county fairs and an earthworm wrastle and aint never seen no stuff like that.

[quack1]

The mouth to the "donut" looks bigger in diameter than the "donut" to the base. Maybe sombody's wierd case forming experiment that didn't work. I'd think that if that case was fired out of battery, there would be a split somewhere.

[justing]

its a brass case and the mouth outer diameter is 9.77mm the doughnut is 13.77mm and O.A.L is 16.81

[oneokie]

No idea on the one with the donut. The other pics look like they were fired in a 40.

its all the same piece of brass i think it was a 9mm round

[Sweetpea]

I'm gonna vote for OOB, but others here (smarter than I) may have another explanation...

Very interesting, and I am glad it did not come from my gun...:holysheep

[km101]

If that fired out of battery, the shooter should have bought a lottery ticket right after that! 'Cause he is one lucky SOB! Could have been serious injury if that case had let go.

[SlippShodd]

I've been finding more and more of these lately.
Left to right: Starline .45 ACP w/.494" donut bulge starting just below cannelure, Win 10mm w/.479 bulge/split to bottom of bulge/case-mouth .456., 2 Blazer 9mms bulged to .430, 2 PMC .380s bulged to .399.

65205

None of them fired by me.

sorry the pic isn't cleaner...

[472x1B/A]

Maybe someone is shooting too fast for their own good, or their weapon.

[Reg]

Spent casings from a Klingon death ray ??

[km101]

Maybe someone is shooting too fast for their own good, or their weapon.

I could understand it if it was one defective weapon, but FOUR??? Not likely. Almost looks as if someone is deliberately causing this. Weird!!

[montana_charlie]

this little gym
... gem ...

[P.K.]

Hmmmmm, duds tossed in the burn pile?

[buck1]

Its the new wildcat 9mm OMG! Very hard to extract! LOL

[TXGunNut]

Its the new wildcat 9mm OMG! Very hard to extract! LOL

Loading the magazine is a challenge as well. ;-)

First pic is the result of a pistol fired out of battery, very close to a disastrous release of gases. Other cases were ammo fired in the incorrect pistol. I always take my time getting set up at a public range, will carefully look over the shooters on either side and watch what they're doing. Most times we just have a nice visit, trade tips and learn about each others' guns but sometimes they need a bit of guidance.
Keep in mind we have quite a few new shooters out there and we'll be seeing lots of newbie mistakes. If we're going to be shooting next to them we owe it to ourselves to help them learn to play our game safely.

[Jon]

I've seen some 9mm that looks like it was fired in a .40. I'm surprised no one got hurt with some of those.

[Chicken Thief]

I see your bulge and raise you a dent.
This is an iron 9mm case.

Man, the stuff people live through!

[TXGunNut]

Man, the stuff people live through!

What's even more remarkable is that many times they don't realize how close they came to getting hurt...or hurting someone else. Favorite is a .308 fired in a .270, happens nearly every year at a rifle range near you in the weeks leading up to deer season. Best I can figure is that a 165gr bullet is probably 1.5 inches long when it finally escapes the muzzle. Bolt can be a little tough to open. ;)
And .357Sigs sound a little funny when fired from a .40 S&W.

[TheDoctor]

Its all that was left after a glock kaboom!

[David2011]

Looks like TXGunNut called it right on all counts. I found a .40 case that had been fired in a .45 once. It didn't split but still glad I wasn't there when it happened. Chicken Thief's example is pretty interesting. That was a very close call for escaping gasses.

[Alvarez Kelly]

Hmmmmm, duds tossed in the burn pile?

THIS makes sense...

Fire softened brass... heat ignited powder... brass bulged into a donut... bullet escapes...

[NSP64]

I think smoeone had a full auto at the range the other day, I found 80+ pieces of 45acp in nice little piles going down range. Like someone was practicing walking supressive fire.
I picked them all up. LOL

[justing]

yes sorry gem (damn auto correct)

[GL49]

I ain't never seen no earthworm wrastle. I gotta get out more. I've seen some of the others at the range once in a while. One time it was at a police qualifying shoot, one of them couldn't figure why he was having trouble with his 9mm. "Umm.... sir? You're trying to fire .380's."

[SGTM9]

Scary stuff.

[Down South]

Found this one at the range that I frequent. I figured someone fired it from a 45.

[452460]

OP and Chicken Thief, those cases gave me a good chill.

[4719dave]

Bump fire stock on a 9mm ar been there ot a good time .............

[SciFiJim]

Looks like a conversion from Asperly Aimless to .40 S&W.

[oldgeezershooter]

It's a new round that headspaces on the bulge!

[fatelk]

It's a new round that headspaces on the bulge!

I like it!

As to the .44 mag in a .45, an acquaintance told me once that that's what he liked most about his .45 Colt; he could interchange .44 mag ammo in a pinch. He got upset when we tried to tell him he really shouldn't do that. He angrily retorted that he's shot a bunch of them that way and it worked just fine.

I was embarrassed a while back when I shot a magazine full of .380 through my CZ82 9mm Makarov. I wondered why my marksmanship was so bad, until we we were getting ready to go and I started picking up my bulged brass.

[SlippShodd]

I don't get it. As much of a moron as I can be sometimes, I just have a hard time getting my head around shooting a 9mm round in a .40 or a .40 out of a .45. And by the way, that was my conclusions as well on the fired rounds I found and posted the pic of earlier. I can almost see the thing about similar rifle rounds -- you're a complete dope and you figure if it fits, it fires. I also understand dropping rounds in a revolver cylinder and if the rim is big enough to catch without falling through to the barrel, you're in business. I think Elmer or Skeeter used to describe doing that on purpose with certain calibers in the Colt P when ammo was scarce. I don't own a .40 so I can't go see if I can fill a .40 mag with 9s without them all hopping out the top before I get it up the well of the gun. I think there was another thread on here a while back that explained that if you get lucky (?) and the round strips out of the mag and manages to wedge in under the extractor, you'll stand a good chance of igniting the primer. That's real good to know I guess, but how can people be so friggin' stupid?
I get real observant when I'm sorting my brass after a mixed session: .44 Mag looks a lot like .45 Colt looks a lot like .44-40. I've seen .45 Colt brass loaded as .44-40 and vice-versa, and that ain't too big a deal, but I sure don't want to drop a round in my Henry replica with a .44 mag load of 2400 in it. Makes you pay attention.
I hope that .44 Maggie round in the previous post went through a Casull and not a SAA. Fewer pieces to take home that way.

[MtGun44]

I have, upon occasion needed some sort of a "punch" to adjust a sight or for some other
reason while on the range, and picked up a piece of scrap brass and hit it with a hammer
to drift a milsurp front sight. The piece in post #25 could be something like that.

The original looks like an out of battery firing of a 9mm in .40 or .45 chamber.

Spent casings from a Klingon death ray ??

I thought everybody knew that Klingon death rays were actually phased energy weapons, ie no casings.

Excited coherent light rays are discharged through a phasing mechanism which regulates the power setting (stun, heat, kill, disrupt(dematerialize) and detonate.

Newbies...

[SOFMatchstaff]

the original picture is quite common, I have several on the shelf in the loading room right over the scales. It is caused by a open bolt subgun firing slightly pre maturely, usually because of a dirty chamber. You wont find this bit of high pressure artistry in any pistol, because the bolt/slide mass is to light to retard the ejection cycle enough to get the glass blower effect. I,ve seen it in 45, 9mm, and 9 Styer.

the other pictures are way to common, the gene pool trying to cleanse its self. Luckily for the guns sake, the larger bore in relation to the ammo fired lowers the peak pressure, and saves the gun. there are a couple combos that scare the beejesus out of me tho... think glock in 357sig and a 40 with a bit of a high primer...eeeww..

[Boerrancher]

The worst I have ever done was fired a cylinder of 44-40 out of my 45LC. There was a fox after my chickens and I was in a hurry. The 44 and 45 ammo were in the same colored plastic box. After that incident I started keeping my ammo in different colored boxes, and no I didn't even come close to the fox. The low recoil lack of accuracy was my first clue that something wasn't right. When I ejected the cases I couldn't understand why they didn't look right and then I saw the head stamps.

Best wishes,

Joe

[Harter66]

In all of my junk I've a steel 223 fired in a 6.8 .

FWIW 9s load fine in 40 magazines ,feeding works too. In M&P type anyway.

[montana_charlie]

He angrily retorted that he's shot a bunch of them that way and it worked just fine.
Isn't it interesting how that works?

If a person is doing something in the wrong way, but doesn't know it's wrong ... he will usually take your word or look for confirmation elsewhere if you tell him it's wrong.

But, if the person responds with anger it almost always means he knew it was wrong all along, but felt the need to 'get by with something' ... so he is angry about 'getting caught'.

[FISH4BUGS]

Those more than likely came from an open bolt gun that fired before the cartridge was fully seated in the chamber. I have a Smith & Wesson 76 9mm submachine gun that would do that all the time if I did not use a Lee Factory crimp die in the last station of the Dillon 550.
No big deal. I had a number of them rupture with no bad effects....but then the 76 is built like a tank.

I bought a box of 45 40 cal rds after someone at a major gun shop in Billings sold a man a High Point 45 and a box of 40 ammo. No one was hurt but 5 shots went bang. I was in line behind the man.
