Fire formed case. Oops moment

[Low-Pressure]

I was sorting my brass when I found this. Looks like someone had an OOPS moment at the range . I guess this happens more than it should and shooters need to pay attention when loading up their magazines.

I got some range brass from a LEO buddy of mine and found 7 9mm cases that were fired out of a .40 and bulged/split like that. I mentioned it to him and he said that one of the other officers brags about the money he saves by shooting 9mm instead of 40 while practicing. Just goes to show how little some people know about the firearms they carry every day. The sad part is that apparently he can't tell the difference accuracy wise between 9mm and 40.

ROFL...good one!

ahh, the infamous 10-9mm luger. With it's unique Keyhole(TM) technology that allows it to cartwheel through the target, guaranteeing maximum damage to anything you're not aiming at.

ShootinMedic: Perhaps the LEO mixed up the use of a .357/.40 SIG mag loaded with 9mm in a 9mm SIG with just shooting 9mm out of his .40?

Wow, I've never seen that particular ooops. My mind is officially boggled at people's outright stupidity at times.

most of the 9ina40 brass i find has a much nicer mushroom shape to it.. must be the double magnum loads..

I worry about this myself sometimes, though with .380 auto in my 9mm. I rarely load .380 or find brass for it, but even when I do I just leave it at the range. Just seems like I'm asking for something bad to happen when I throw 2 pieces of once fired .380 brass in with my bulging bag of 9mm. Of course I sort through it later, but the .380 and 9mm cases can be hard to distinguish. Whenever I find one or 2 .380 cases and no one else is shooting, I wonder, did I run those through my xd9 and not realize it?

I have some .380 S&B brass that says 9mm on the headstamp. Talk about confusing. I don't hand load 9mm though, so no confusion there.

More common than you think. I found one last year at Chabot. A 10mm fired in a 45ACP...

You can tell the difference when you put them in an ammo tray. The 380 is about 1/16" shorter than 9mm, so you can see it when you look at an angle.

I use the trays that come in federal or blazer 40 or 45 boxes.

I don't think so. My buddy said this other guy was trying to get other people there on that range day to try shooting 9mm out of their 40s "because it is so much cheaper" this was with his own backup gun as the department uses 9mm not 40. He described this guy as a Grade 1 idiot when it comes to firearms knowledge who thinks he knows everything about firearms and will not be told otherwise.
