I am sure that I saw something about this in one of the forums here, but I can't find it. I seem to remember a thread about some sort of .22 ammo that was very low power. I think it said something about the round being loaded with a priming charge but no propellant. I am wanting to say that whoever the poster was, he was using it for practice for cowboy action shooting. IIRC, it didn't go too far or hit too hard, but it had enough punch to ring steel targets. I am wondering two things. First, would it be enough to drop a squirrel within 40 feet or so. Second, where would I go about getting it? I may never use the stuff because I would still hesitate to bring a rifle out to shoot in my back yard. The neighbors are easily frightened by evil, nasty guns. I am none too sure I would get by with a Red Ryder BB gun with these folks. Worst part is that the one I think would give me the most trouble is a certified gun nut. His are OK; mine are not to his way of thinking.
