I've seen a couple packages of these at one of the local box stores, and was curious about them. I was thinking about asking here, did a search on the CCI web site, and decided they weren't good for my expected uses. I don't have a vermin problem where I live. The warnings alone tell me to avoid them in a semi-auto pistol. If I had a revolver and a vermin problem, it might be a different issue.
The next day, my YouTube feed shows me a two year old video of a guy demonstrating these things in 9mm. In short, the video confirmed for me that leaving them on the store shelf was a good choice. I'm not even sure they'd do much damage to vermin at fifteen yards, although they would at least induce some pain...
