So What Happened....Care To Guess

[runco]

Let's see who are the intellectuals or just the folks full of wisdom. You care to to guess what this is.....(I will answer after a few posts if no one gets it, I suspect it will not take long).

9mm in a 40?

[Caster]

Looks more like a reloading mistake. Trying to shove a 40 bullet in a 9mm case. I've seen similar cases where 45 bullets were shoved into 44 cases.

Or .40 in a .45?

but the primes have been shot.

Okay, I couldn't tell on my iPad.

I'm with you then, fired in the wrong chamber.

Wrong size decapping and resizing die?

Round fired in the wrong chamber?

.32 cartridge fired in a .380

That is a .45 sig. 40 cal brass necked up to a 45 cal bullet. They don't feed reliably

[jtmaze]

It looks like wrong chamber here as well

Once I was at a three gun and my buddy shot a 223 round out of his 7.62x39 AK. He could barely get that expanded/split case out of the chamber. I do not think that picture is an example of 9mm in a 40 or40 on a 45, etc, etc. If that is what happened, I think that brass would be split to hell and back.

It is actually not all that uncommon. When I am picking up 9mm brass at the range, about every 6 months, I see at least one of these. And also not desireable but probably will not hurt a gun or the shooter unless the case ruptures. There aren't a lot of pressures there because the bullet has no resistance.

To give you an idea of what you can do when there are no resistance look at this video:

Not a bit of damage when firing a 50 BMG from a 12 gauge single shot. I would not try this and I suggest you do the same.

Spolier alert: I had a play date with my Sig P220, P228, and a recently acquired Sig P6. Well I shot about 100 rounds through the P220 first. Then I shot the P228 or so I thought. Had a very low recoil shot and a stove pipe in my P228. Then I removed and shot again, same thing again. Upon closer review, I did not have my P228, I had my P229. I had removed the mag at the house, as to not shoot my Hornady's home defence loads, grabbed the P228 mags loaded with 9mm FMJ. Well, a 9mm will shoot in 40 caliber. What an idiot I was. This did teach me that I need some type of system to make sure this does not happen again!

[dralarms]

Yep, done it before.

Well that shows what I know. I would have thought the case would have ruptured or split or something. Maybe that is why I only have 9mm pistols.

[TMF]

Done it before too with a Beretta 96. Loaded up mags with 9mm; couldn't figure why it wouldn't cycle. Fired half a dozen rounds before I figured it out. Facepalm moment.

[Curiousgb]

Don't feel bad. I was shooting with some friends in SoCal, one was an EOD Navy guy. He shoved a 40 in a 45 magazine. It looked just like your pic.

I've only run wrong ammo by using .22lr in .22 mag revolver cylinder a few times, but on purpose just to see results. The case fire forms to expand pretty much evenly all the way back to rim, though.

I have wanted to do that, but thought 22lr bullet would get hung up on the lip (if there is a lip).

I wish they'd have had a chronograph!

If only the ammo was labeled in some fashion...

Perhaps color coded.

Tried once or three times myself, the only issue we had was the jacket getting shaved by the forcing cone. At least that's what it looked like was happening. I wouldn't go out of my way to so it again, seems the acurracy wasn't great IIRC but if I was in a pickle it'd work.
