I've shot some in my 30-30s. It will scare the heck out of varmints but that is all. They don't group, it's more like pattern. 6-7" was about the best I could do. I thought I was shooting my SKS. Some hit the target, some flew completely off the plywood that the target was stapled to. It would be great if they could make them accurate. I only ordered two boxes of the stuff so it was not really that big of a loss.
