4/4 CCI .22LR Shotshells split/ruptured?
I found a 20rd box of CCI .22LR shotshells in my stuff earlier, can't be much more than 5 years old or so. Maybe 7, tops. I noticed I had apparently fired a couple, and returned the empty brass to their trays in the package. I went out and fired off two at an empty can in the dark. Both were surprisingly quiet. It's a cheap Savage bolt-action, and the first shot apparently cycled fine. I realized when I got home that the second shell had stuck in the chamber, and wouldn't extract. I pried it out with a mini screwdriver, and found it had a jagged split all the way down the length of the case. It wasn't until later I noticed that both of the older shells I had replaced in the box were split identically. I don't know about the one that's lying beside the road; I'm going to go look for it tomorrow, just out of curiosity, but that's at least 3 out of 4 rounds spilt open already. It can't be the gun, because I'm 98% sure I bought this box of shells before I bought this rifle (I'll try them out of my revolver tomorrow too, but they aren't going in my late grandfathers 1934 Winchester single-shot!). I'm guessing that all 4 shots are split, out of two different chambers. Why would they do that? And is it dangerous? I hear people in other forums talking about split .22LR cases and how "they would have lost their eyes if not for the shooting glasses", but in this case I was surprised at the very quiet report, although that could be because having spilt, the case never developed maximum pressure, or maybe because a bolt action is safer than a semi-auto? I wouldn't have noticed anything if the round hadn't stuck in the chamber and I hadn't looked it over after extracting it. Apparently the first two rounds didn't stick, because I would have noticed they were split (honestly, I don't even remember firing them, but I think I would have remembered that. I have no need for shotshells, really, and just bought them out of curiosity.)
