i know this thread may have seemed silly at first, but the point of it was to let people know that "shot placement", is not something you can fully count on.
i think it is crazy to assume that when your in a life and death situation, your going to be able to put your shots in certain places on your targets body.
That's why I get such a kick out of the guys who...in a shootout...think they will hit com, hit a threat while on a full run, hit a threat in the dark, run a zipper, shoot upside down, blah, blah, blah.......
Here's a small dose of reality for the over-confident and the uninitiated:
"Tactical Realities:
Shot placement is an important, and often cited, consideration regarding the suitability of weapons and ammunition. However, considerations of caliber are equally important and cannot be ignored. For example, a bullet through the central nervous system with any caliber of ammunition is likely to be immediately incapacitating.
Even a .22 rimfire penetrating the brain will cause immediate incapacitation in most cases. Obviously, this does not mean the law enforcement agency should issue .22 rimfires and train for head shots as the primary target. The realities of shooting incidents prohibit such a solution.
Few, if any, shooting incidents will present the officer with an opportunity to take a careful, precisely aimed shot at the subject’s head.
Rather, shootings are characterized by their sudden, unexpected occurrence; by rapid and unpredictable movement of both officer and adversary; by limited and partial target opportunities; by poor light and unforeseen obstacles; and by the life or death stress of sudden, close, personal violence.
Training is quite properly oriented towards "center of mass" shooting. That is to say, the officer is trained to shoot at the center of whatever is presented for a target. Proper shot placement is a hit in the center of that part of the adversary which is presented, regardless of anatomy or angle."
