40 Cal. fired in 45 ACP.

[kmbrman]

My son and I were at my range both firing our Kimber 45 1911s , when we heard what sounded like a dud shot ! FIRING at 25 feet , we saw no holes in the paper target ? My son pulled the slide back and saw a 40 s&w round fired in the gun but the caseing was stuck like concrete. With a brass cleaning rod we pushed it out , the case was split from mouth to the base but there was no damage to the barrel! Moral here is to always check your rounds ,if you fire more than one caliber pistol. I don't know if other tight chamber pistols will fire a 40 cal. or not , but always check your mags!

it happens. Always good to be reminded.

I found a 9mm case that had obviously been fired in a .40 chamber.

Ummm I know this guy, who is a good friend of mine.... who ummm fired three successive rounds of .40 through ummm his 1911 and ummm couldn't understand why ummmm his gun had developed a bit of a jamming problem all of a sudden.

This ummmm "friend" has since learned his lesson.

Good strong gun that 1911.

Had that happen too. Took a 'crazy foreigner' to the range to shoot magnums, 357, 41 and 44. I assumed he knew what he was doing, and he did for half the session. He fired one shot with the 44 Mag and complained the gun had jammed. Not thinking clearly, I was able to turn the cylinder by hand and gave it back to him. He had loaded all 6 chambers of a 44 Mag with 41 Mag cartridges. He fired the rest with little resistance in turning the cylinder.

Yep, all split from mouth to rim (or rim to mouth. Not sure what ruptured first!) The gun is fine (S&W 629) but he totally destroyed six perfectly reloadable 41 cartridges.

Fired a .40 from my Colt Defender .45. Same cracked casing. Let a friend load the magazine, but that was the last time.

It happens to all of us from time to time.

I once fired a 7mm Remington Magnum through my .300 Winchester Magnum. I will never buy ammo off a gun show table again without checking it out first.

If you guys got .45s, what the hell you doin with .40s?


Runnin for cover

 

[cerberus65]

I once tried to load .40's into a .45 magazine. On the 4th round all 4 would pop back out. Took a couple of tries before it dawned on me what I was doing. Doh!

At least the .40's never got close to being chambered in the .45!

And after shooting .40 and .45 side by side like that I determined that I really don't care for .40 and really, really want a .45. So I don't expect to ever have that problem again.

I'm not too sure on that....It reminds me of the thread on ND's/AD's where a similar comment was made...My own feeling is that it should never happen.

 

[CountGlockula]

There should've been a significant difference in bullet size when loading in a mag. Glad you both were safe.

 

[kmbrman]

CountGlockula

You would figure the mag lips would let the 40 slip on out ,I guess you just never know !

"If you guys got .45s, what the hell you doin with .40s?"

I've got maybe 2K, maybe 2.5K police .40 S&W dirty brass I'd happily trade for 70% return in .45 ACP once fired dirty brass. It's about a 5 gallon bucket worth, sorted by caliber only.

 

[cornman]

That is impossible. The .45 is like 2" bigger than the .40 hence all that "stopping power".

 

[Scratchshooter40]

Just a little prop . . . .

I keep a .45 ACP case, .40 S&W case, and 9x19mm case stacked one inside the other with me when starting a student on handguns. It gives them a perspective of caliber relational sizing. I also keep unfired FMJ bullets for reference for shooters starting out. I also stress the awareness of weapons that take multiple calibers like the .38 spl/.357 mag in revolvers. Just be careful and aware. I'm glad no one was hurt.
