If you're aiming, and aiming small (and not sprayin' and prayin'), you're probably not missing your intended point of aim by much. And if you're only missing point of aim by just a little, you're probably still effective. For instance, a small miss from the center of the chest puts one right through the heart, or to the other side, a lung, etc.
Thanks, FP. Great description.
Plus, it was a line I stole from Mel Gibson in "The Patriot" (giggle) ];-)
