Things you see when your a range rat.

9mm shot in a 40s+w-----not just once but four times . fire forming at it's worst

32 shot in a 380

These are the worst, I just hope they never become popular, plastic 38spl

Holy ****!

Did you also find a shattered pair of glasses and someone's nose near that brass?

I usually just find a small handfull of unfired live ammo whenever I go to the range.

reminds me of a classmate of mine who was learning to chamber a barrel.... it was so poorly done, the teacher didn't just fail him and make him redo it, he explained that he just created an unsafe wildcat, and would he please try to endeavor to keep his body parts attached? He was trying to chamber a barrel in .308, and was so off-center with the reamer that he blew out the shoulders and stretched the brass real thin.... instead of the normal powder capacity of 40-53gr. (depending on powder), his case held 84gr....

I'm surprised that the 9MM would even fire once in a .40 much less several times. It looks like the bullet would just be so loose in the chamber the firing pin wouldn’t be able to get to it. So I conducted an experiment. I had a couple of my 9MM and .40’s right here with me. I loaded a .40 mag with 9MM and cycled them through my 4006. They all cycled except for one. :what: This could make for a bad experience if the rounds were fired in a composite framed pistol or any pistol for that matter.

I shot a 9mm though my 45acp once. Didn't even go bang, it made more of a soft popping sound. Bullet left the barrel and the brass was fireformed to the point where it split like crazy.

I was surprised that it worked at all but it was purely accidental.

I hear the extractor will hold the 9mm against a .40 breech face well enough to ignite the round when the trigger is pulled. Personally I've never tried it (even cycling the ammo, that is).

I wouldn't think the frame material would matter as its not really a pressure containing component.

I thought I was the only one who found those! I've also found .40 S&W that have been fired in .45 acp, and 357 Sig that were fired in a .40 S&W barrel, which wouldn't cause any gas leakage, but the accuracy would greatly suffer.

In my experience, the two most common are the .380 in a 9x19 barrel, and 9x19 in a .40 S&W barrel. A couple of months ago, some rocket scientist at our range put a whole box of 50 9x19 through a .40 S&W. I didn't see him do it, but it was in the brass I bought from the range.

In most semi-auto pistols, the extractor will hold the case against the breech face firmly enough to allow the primer to ignite. That's why they print the caliber on commercial firearms and on the boxes of commercial ammunition, in the hope that someone will actually read it.

Hope this helps.

I've found the same 9mm out of a 40, brass:eek: It's not as bad as it looks, as the chamber can't build much pressure, but finding that many makes you wonder about the shooter. I've also found the 9mm bullets laying on the ground after being shot out of a 40, you could reload them babies, not a mark on em:D

It happens.

Went to a friend's to shoot and one handed me the rifle and the other handed me the ammo. Without second guessing them, I attempted to put a 30-06 in a 7mm Mag. Luckily, it wouldn't load.

Another gun, my brother fired a .270 Win in my 7mm Mag. 75$ for a new bolt body(2 months to find it and ship it), and 75$ to gunsmith to install. No one was hurt.

Yes, I've also found .270 brass that was fired in a .30-06. They probably wondered why their treasured deer rifle was suddenly not hitting the target.

I've seen 40sw through a 45- not nearly as exciting as i expected it would be. Not something i'd care to see again either though.

I made the 9mm/40 mistake once in my Sig. I loaded the mag and started shooting, about the 3rd round the recoil felt less and the case did not eject.

The gun had chambered the round and was probably held by the extractor.

I wouldn't recommend doing it but I don't think it would necessarily be dangerous. :scrutiny:

Last year my sister brought me her Ruger M-77 II Stainless .30-06 after she missed the biggest buck she'd ever seen at a range of only about 50 yards. OK, I admit I initially suspected Buck Fever and the world's worst case of 'The Flinch'. But, I proceeded to check out the rifle and scope for mechanical issues and found none. At the bench, I got 1.5 inch groups at 100 yards with factory ammo. I gave the rifle back to her with advice to stock up on some managed recoil ammo and spend some time at my target range. She was not amused.

This year as I was cleaning out the blinds, I found 20 .270Win cases that had been fired in her .30-06! I guess I never considered presbyopia and vanity as serious impediments to marksmanship with a scoped rifle. Apparently she shot all the .270Win ammo because she laid a fine 12 pointer on his side opening morning this year.
