Head Scratcher?
Well I thought I had seen just about every kind of mutilated, cracked, split, and separated brass out there but these have me scratching my head? When separating brass from our last range trip (indoor range) I found 4 of these they had all been fired, brass was dirty primer has been hit. They are 9mm cases 3 different head stamps so I presume they have been reloaded. But the top half of the shell has been expanded to the same size as a fired 40s&w brass they even mic the same at the mouth. I didn't find them till after they went thru the tumbler for about an hour ready for decapping so they have been partially cleaned.

Idiots putting 9mm rounds in .40 guns.

Re: Head Scratcher?
We thought about that but with the brass being shorter not sure it would set off the primer. Also wouldn't there be a lot more brass deformation or splitting.
What ever they did they did it at least 4 times.

Morne's probably right....
In many situations, the extractor will capture the shorter case, and hold it well enough to let the firing pin ignite the primer. The 9mm is just close enough to fit, line up, etc., otherwise.
If you've got an M&P9, it's magazines will fit an M&P40, and should feed properly, although ejection might fail.
Not a good idea, but the .40's got to be solid enough to deal with a 9mm that way.
(If you have an M&P9, either full size or compact, the slide & barrel will interchange with a same-sized M&P40.)
I expect that the Glocks will do that, too....
I won't admit it, but somebody with my initials once put a full magazine of .380's into an old S&W M39-2 (9mm semi). First round fired. Ejection failed.
Regards,

Re: Head Scratcher?
Yeah, that's exactly what it is. Extractor holds it and when the round goes off, it never reaches anywhere near it's pressure potential.
It's careless and paints a bigger picture of the type of people who end up doing it, but it's simply not really all that dangerous... specifically in the case of 9mm in .40cal guns.
If you collect enough brass, you'll see them in a myriad of head stamps. I have a .357 Sig piece that must have been shot from a .40cal pistol as it's completely ironed out, hard to tell it's not a piece of .40 brass until you read the head stamp.

I like to swap brass... and I'm looking for .32 H&R Mag, .327 Fed Mag, .380 Auto and 10mm. If you have some and would like to swap for something else, send me a note!

Re: Head Scratcher?
We had an instructor candidate do that with a 40 in a 45 with the same results about 8 years ago. He didn't pass on the first try.

In both cases, the round did not discharge. It did however, leave me in quite a state of brief confusion to watch the entire round, brass and all, come out the end of the barrel.
Here's a video of a guy that says he shot 9mm through a .40. Fast forward to 3:20; the case looks a heckuva lot like the images above.

Re: Head Scratcher?
Thanks for all the responses guys kinda what we thought just didn't know about the extractor grabbing the brass enough for it to be set off.
Another one to go in the crazy brass box! LOL
That had to be a really weird sounding round you would have thought they would have noticed before 4 rounds were fired.
And kind of surprised it cycled the action enough for them to fire those 4 rounds.

Re: Head Scratcher?
It could be that they did it on purpose, too. Most likely, if I had to guess, was that they had similar handguns out and in use, and someone most likely stuffed the wrong mag in to one of the guns. And if it was a newer shooter along for the day, it may have been that person that didn't notice right away what was going on.
.40 S&W was designed specifically to be very close in dimensions to the 9mm and handloaders know that they use the same shell holder/shell plate. The rim is a wee-bit bigger on the .40cal, but the extractor groove is basically the SAME. Fitting 9mm rounds in to the breech face of a .40cal pistol is easy... and natural.
The .40 S&W was born in 1990 as an alternative to lightly loaded 10mm ammo. That's why we even have .40 S&W in the first place. S&W made huge 3rd Gen 10mm pistols and someone campaigned for the 180 grain bullet to be dropped from 1,200 FPS to 950 FPS. (I say "someone" because it's a point of contentious argument, it seems...) When Winchester, at S&W's request started making lighter 10mm at that speed, Smith & Wesson said "you know... we can do this with a smaller cartridge... and fit them in to 9mm-sized handguns..."
Glock then shanghai'd Smith & Wesson by releasing a .40cal pistol before Smith & Wesson could get a .40 Smith & Wesson pistol to the market. Evil!

Re: Head Scratcher?
Unless my memory fails me, I believe Ruger beat S&W to market with a .44 Magnum back in the mid-50's with a similar story.dan dan the XD40 man wrote:One of my favorite storiesSevens wrote:Glock then shanghai'd Smith & Wesson by releasing a .40cal pistol before Smith & Wesson could get a .40 Smith & Wesson pistol to the market.

Re: Head Scratcher?
I found a couple of cases exactly like those last summer. I meant to ask someone about it, but got busy and forgot.

Re: Head Scratcher?
I was sorting brass yesterday and came across the very same thing! I had the same thought as to what had happened. Found about four so far...
