Okay guys, this was an accident, as I would never knowingly shoot incorrect ammo from a gun without proper adapters, especially a rimfire out of a centerfire. The crazy thing is though, when I went to Indy Trading Post in Indianapolis, I bought a box of S&B .25 auto. Basic FMJ stuff, just to test out a a 50+ year old Tanfoglio pocket pistol. It worked fine. Here's the thing though that I didn't realize until afterwards... one of the fifty bullets in the box was NOT an S&B .25 ACP round. It was some kind of .22LR with a capital "C" on the back. It is clearly a rimfire cartridge. I don't have a .22 anymore but I used to, so I know what I'm talking about. The crazy thing is that it WORKED, and the slide chambered the next round. *** GUYS? Should I be upset or amused? I think I'm disappointed in the shop for placing a .22 in a box of .25s, as I am absolutely certain it did not come from S&B this way, since it doesn't even say S&B on it. I don't really feel like I could complain to the shop though, because I highly doubt they would believe me as it has now been a couple days since this happened. At least now I know to check the rounds before loading them. Btw, what company has a C on the back? I don't think it's CCI, what is it?
 
Could be centurion. There ammo is dirty junk at best, even by rimfire standards. I wouldn't expect it to work though. 1 would expect to notice the difference though.
 
Why do you believe the empty came from your gun? Are you sure it wasn't on the floor already and you picked it up instead of yours? Can't believe you wouldn't noticed it when loading or that the mag would even retain a 22lr round much less chamber, and extract.
 
22lr is longer, thinner, lighter, and rimmed. You would have noticed the difference. Do you have the brass that you think came from the .25? Does it have a firing pin punch in the middle? Is it blown out to .25acp dimensions? If you have it, I would love yo see a picture.

How would it have headspaced?

This.
 
Just want to point out that if you are correct and a .22 round was in a box a 25's it isn't necessarily the shop that messed up, if their ammo was on the shelf customers have access to it was more than likely another customer.

That being said the most likely scenario as others pointed out is that the .22 casing was already there from a previous session, its hard to believe you handled the round and didn't notice there difference and then shot it without feeling any difference.
 
I don't think you loaded a 22 into a 25 without noticing, and I don't think it would have chambered and fired even if you could
 
I can't see a rimfire .22 even igniting in a .25 centerfire pistol.

This.

And the post of finding the rimfire case on the ground left over from a previous shooter.

i also find it difficult to believe a centerfire pistol would set off a rimfire round, even a 25 ACP pistol.

If so, I guess Thompson/Center wasted a bunch a money putting dual firing pins in the Contender
 
A few things wrong with this deal here.

1. A .22 LR is about 1/8" longer then a .25 ACP, and won't fit in the box, or the magazine.
2. A .25 centerfire firing pin will not set off a Rimfire round.

So, despite what you think happened, it didn't.

I don't know how someone would confuse a .22LR round with a .25ACP round when loading a magazine. The two rounds are very different in appearance and in how they feel.

I don't know how a rimfire would fire in a centerfire gun given that the firing pin is going to hit in the center of the cartridge base, not on the rim where the priming compound is.

Even assuming some bizarre circumstance that allowed the center hit to set off the priming in the rim, I don't understand how the .22LR round would have presented its rim to the firing pin given that the rim diameter of the .22LR round is so small that the case should have moved forward into the chamber so that the rim was basically resting where the case mouth was--about half an inch too far forward for the firing pin to reach it.

Could it happen? I can't say it's totally impossible. But it's certainly extremely unlikely.
 
Nope, firing pin strike would be way off along with the other issues mentioned here. You may THINK it happened...but I'm pretty sure it didn't
 
22LR will NOT fit in the magazine of my .25 Titan (made by Tanfoglio) and the round falls too deep in the chamber. a 22 short won't even seat in the magazine.

Relax, You picked up a fired case.
 
Yeah nevermind guys I'm just stupid and was quite inebriated when I posted that yesterday. Don't worry, I'm always sober when I go shooting though.
