This is inspired by another currently running thread and the fact that I've seen a number of members post that when a .22 is their weapon of the moment, that they plan on head shots for stopping effect. The story in the above thread is that of a former Spec forces guy who shoots a young scumbag in the head (direct hit) with a .22 pistol. The round did not penetrate. Didn't glance off, simply didn't have the energy to penetrate. This has also been my experience in the field with a .22LR (out of pistol) direct hit to the forehead. (Never seen one out of a rifle, article did not say if a LR orshort was used)
I'm not trying to argue or play "your wrong, I'm right." I just don't want one of my friends (that'd be you) to waste time giving the BG what amounts to a punch in he head instead of actually doing damage. As a friend I'm asking you to consider multiple COM (or even better, IMO just above the sternum) shots as a better method of incapacitating a BG. I have seen this stop a person.
