Yep seen the same thing with a 32 S&W round in a 38 S&W revolver and a 40 in a 45 ACP.:banghead: Must have been some really poor on target performance.

Wow, that's from some "generous" factory chamber ... could be the "Glock bulge" everyone is talking about ... 
Just kidding!
Yup, 9mm fired in 40S&W barrel.

A .22 short brain, firing a 9mm in a 40 cal bbl.
Probably had two or more pistols on the range bench.

If I am shooting Glocks with different calibers at the same time (I often do), I put a piece of masking tape on the bottom of one caliber so I don't grab the wrong magazine (you can even use different color masking tape to color code for caliber).
We also did this while shooting USPSA matches and put our initials on the masking tape pieces so we could identify who the owner was when magazines were found.
If you are shooting multiple Glocks or pistols of same brand with other shooters, using initials on masking tape will prevent mixing of magazines.

I've seen stuff like that happen quite a few times over the years. Some folks just don't pay close enough attention to details. Most KB's are the result of carelessness, the result of lack of attention to detail while reloading.
The worst was a few years back when my Son reached into my ammo closet and grabbed what he though was a box of 7mm RM, but it was actually .270 win, wow. I spent a pretty good amount of time picking bits and pieces of .270 win. brass from the chamber and bolt face. The bolt face actually got set back, and there were pieces of brass embedded in every nook and cranny. Fortunately the 700 action was strong enough to contain such a catastrophic event.

Worst I have seen was the remnants of a .410 break action that somebody (bless their heart) crammed a 30-30 into supposedly. The barrel ruptured about a foot down where the taper starts getting thin and the barrel peeled out like a banana peel. I doubt a 30-30 would do that due to plenty of space for pressure bypass in the bore, but supposedly thats the story. Experiments happen but they are very much ill advised. Negligence on the other hand can be just as bad.

Yup, that would be my guess. I agree with Walkalong, not idiotic but it is careless.
Stuff happens and luckily it's not all that dangerous, except for the brass that is...

Idiocy was a poor choice of words on my part. I can see now how that could get confusing.
I hadn't thought of having like pistols of different calibers at the range at the same time. When I'm at the range with my friends and were all shooting like guns the other caliber guns stay in the range bags until were ready to switch. I'm glad we have bullet proof walls between us.

I will admit I made that mistake recently at the range.
The wife and I have identical guns, hers is a 9mm and mine is a 40. I don't typically load up a mag until I am ready to shoot. She had loaded up a couple of hers and had them on the bench. I got distracted and picked up the wrong mag. My mistake, I should have looked.
I can tell you the muzzle velocity was 419fps, as I was shooting through the chrono. It missed the target, but at least it did not hit the chrono.

I am old and need to be extra careful. All my 45 ACP's are in the same color pistol bag. All my 9mm/38 Super are in another color bag and my 22 pistols in a third color.
I am most concerned about the 9mm, for which I have a 38 Super barrel. All my 9mm components (barrel, recoil spring plug, magazines) are in the safe when I have the 38 Super barrel mounted and vice versa when the 9mm are mounted.
I don't ever take two different calibers to the range at the same time unless it is a completely different gun, i.e., Ruger Blackhawk 45 Colt or 22.
I try to never have to rely on memory.

That's what I do when shooting by myself. I take one caliber of semi-auto, and one caliber of revolver or if two revolvers they are so different that a mix up can't occur, 41mag and 327fed mag and so on.
I can't shoot two many different types of guns. After the first two different triggers my groups open up like an umbrella so I rarely have more than two guns at the range at the same time.
I rotate them depending on what I feel like shooting , that's probably why I've never mixed any ammo up.

Still a noob
That's pretty interesting (to me), that it would lose that much velocity. I guess that shows that it's true that a bullet fired from a cartridge that's not in a gun does a lot less damage if any. I think I've read that anyway. Really needs the chamber pressure build up.

Yes, that is correct. I'm surprised it came out a 400+ fps. Bet it sure didn't do the inner workings of the pistol any good. That pressure will want to go anywhere before it has to push a heavier object that doesn't want to move.
There have been extensive tests on this.
Potato head,
Have you seen the video of the tests SSAMI have done. If you haven't, you'll like it until you realize how much ammunition they totally destroy.
This video made it's rounds on here a while back.

That's the whole thing, it never has time or opportunity to build the high pressure it needs. It rather surprises me that it made 419fps.

You would think so, but the casing obviously did swell up and form a gas seal. The sound was different (quiet) and very little recoil. I saw the bullet hit the ground past the target and the "419" on the chrono. It did not cycle the action, I inspected the casing when I ejected it. Felt really stupid.
I inspected the gun closely when I got home and saw nothing wrong anywhere. No excessive powder residue anywhere including the magwell or action.Even though most of the pressure, I am sure, leaked around the bullet, there was still 4.5" of barrel in which the pressure still pushed the bullet. In the SAAMI test, there was nothing but the casing - no barrel.

As I have posted in another thread, I have done it -- 9MM in a 45 -- grabbed the 45 1911 instead of the 9mm, loaded up the 9 mag, shot the first round. Weird report, did not cycle the gun and left quite an interesting piece of brass.
My buddy grabbed loaded a mag with 9mm and loaded into the Glock 22. 9MM in 40 -- just like the picture above.
It happens.
And yeah, have to be paying attention.
