.22lr case rupture
Posted: Sun Jul 08, 2012 1:46 am
Have heard of this but in 10's of thousands of rounds this was a first.
I took my Marlin 39A down into my field to test a couple of different brands for accuracy and afterwards was having a bit of fun shooting at cans. One of the rounds went kind of poooof instead of a nice crack. There was smoke coming out of my rifle around the trigger, lever and out of the little hole put in the side of the receiver in case this actually happens.
I ejected the brass without thinking and couldn't find it. I cleared the remaining ammo from the gun, the next one in line was blackened along the side. Took the gun apart, checked for damage. Found none, just a couple of small pieces of brass. The chamber and bore looked normal as did the indention's from the firing pin strikes; so put it back together and loaded one round - worked fine.
I went on a loaded the gun and shot a bit more then gave it a good take apart cleaning. Neither gun nor I was hurt but it is a good demonstration that no matter how unlikely it is to happen it is a very good idea to be wearing some eye protection. Just glad it didn't happen with a high intensity centerfire round.
FWIW, the ammo that did this was Winchester Wildcat bought Friday.Have used this stuff many times.
