I've heard of it happening once or twice to people around here. Not very often though, I think it's a pretty rare occurrence.
22 round going off outside the barrel is fairly safe, neither bullet nor case carry enough energy to penetrate anything. Sure you can get cuts or even loose your eye if you are stupid enough to examine dud up close. Ejected on the ground it will do nothing more than noise.
if you get a ftf, wait like 60 seconds and eject the case, whats a good thing to do with it to insure you don't get hurt from a possible hangfire? i'm abit afraid of just leaving the ejected case around only to have it go off next to me. maybe get a wooden box to eject them into? sure its not common, but neither is getting hit by a bus, but i dont want to take that chance.
Never had a hangfire on a 22, just misfires.
On the subject of danger of an unchambered 22 going off, on mythbusters they fired some off by putting them in the fuse holder of a vehicle and running enough amps through it. The dents and holes they discovered were certainly significant enough to cause serious damage to soft tissue, like one's eyes. Probably would have gone through Buster's scrotum if he had one.
All grounds for not abandoning caution should one encounter an actual hangfire out of chamber.
This is an easy enough experiment to do with a cardboard box in side a wooden box and a hotplate if you would like to try it.
Next outdoor bbq.![]()
