KABOOM!!

Previous owner got a 10mm mixed in with his .45's 10mm case didn't eject and was pushed into the bore and when the .45 behind it went off it blew the barrel, luckily no one was hurt, and surprisingly the only things on the gun that had to be replaced was the barrel and bushing. the gun was locked up solid and took some real work to get apart but hard work and big hammers prevailed :d I put in a new(ish) barrel and bushing I had kicking around and I'm looking forward to taking it to the range tomorrow and seeing how it shoots!

here it is put back together

 
Don't know about 45 and 10, but this is what you get when you mix 9 with 45.

Okay... something isn't making much sense here.

Did the guy have a 10mm case jammed inside a .45ACP case that he reloaded? There's no way it would go through the press without an issue.

Or did he have a loaded 10mm round get mixed in with his loaded .45ACP? Any idiot should be able to tell the difference between the two by looking at them, and therefore the PO was a complete moron who should stick to crocheting :p

Either way, that Kimber fared pretty good, and I hope you got a smokin' deal on it.
 
I wasn't there when it happened but as far as i know a loaded 10mm got mixed up with the .45 and was loaded into a mag, 10mm fired, but didnt eject the case, next round pushed the empty 10mm case into the barrel.
Whats left of the 10mm case is still in the barrell with a 45 projectile behind it.
 
Not that is makes any difference to what happened here but I would've thought a fancy Kimber like that would have had a ramped, fitted barrel.

Looks like the one that ate the fired 10mm casing & then split when a .45ACP was fired in behind it was a traditional style barrel, with the normal lugs [non-ramped]?

I think the lesson to be learned is that we must be careful, I came very close to firing a second round into a bullet stuck in the barrel due to a squib that felt and sounded like a misfire. (revolver)

The only Kimber I've owned with a ramped barrel was chambered in 10mm, all the ones I've had in 45 acp have a standard 1911 ramp.
 
Wow I'd say he is lucky that nobody was hurt. I bet he will be paying close attention as he loads his mags from now on. Hopefully you got the gun at a good discount. It's easy for us to point and say how obvious it is, but mistakes happen, especially when we get complacent.. so lesson for everyone is pay attention.
 
So I take it a 9mm round was shot from a .45 gun. That would explain the case expansion.
I wouldn't have thought that a 9mm mag would fit a .45.

It was fired in a 45cal gun, I've done it in purpose with 9mm and 40cal in a 45 1911, although I couldn't get the 9mm to go off. Nothing bad will happen as there is no chance for pressure to build.

And 9mm 1911 mags are the same magazine accept it has 2 ribs in the mags to keep the 9mmnrounds centered in the mag.

yep, and its usually the small simple stuff that ends up biting you in the ass, I'm giving the blown barrel to one of the RPAL instructors in my club to use in his course, so anyone taking their RPAL in southern New Brunswick will be able to see first hand what can happen if your not paying full attention to what your doing.
