Yesterday I took my sons father in law and his father in laws father in law to the Gun Club range that I am a member of.
They had bought several new guns that they had just purchased so they wanted to check them out. It was a beautiful day, not to hot, not to cool and between us we shot several hundred rounds.
I only brought two guns to shoot this time(rare for me) and a Dillon shooters bag full of .45. I was shooting one of my Government Model .45's just because it had been awhile since I shot that particular gun, and I needed some trigger time with a gun that I conceal alot, a Sig P225 9mm.
The guns they bought were mostly defensive guns, a S&W M&P a few various makes of Taurus and the .45/.410 Judge.
Naturally, we all exchanged guns and shot up everything we had. Everything went well until my .45 locked up. My son's FIL was shooting it and the slide wouldn't go into battery. Thinking that it was crudded up from having several hundred rounds shot through it I told him not to worry and stuck it in the case that it came from.
Today I took it apart to clean it and much to my dismay, found that the barrel was bulged to the point that the slide wouldn't retract past the point of the bulge. The slide was sticking on the bulged part and a knock on it with a leather hammer freed it up.
Only one thing could have happened. Sometime while all of us were firing, he must have had a squib and not noticed it. The gun cycled like normal and the next shot ran into the lodged bullet and bulged the barrel to the point of failure. It didn't come apart, luckily, but the barrel is useless.
As soon as I get some batteries for the camera I'll take a picture of it.
Its just goes to show that anything can happen at anytime. The ammo he used at that moment was commercial ammo they purchased at Gander Mountain in Little Rock, it was a brand that I had never heard of. There were a couple of misfires in that box, that had good primer strikes but no ignition, so I'll go out on a limb and say that it was ammo related.
In the meantime...one of my guns is down.
Looks like I'm about to order another barrel.
