want it on game animals. You want the blood trail that the exit wound provides, and you want the pneumo-thorax(collapse of the lungs) caused by having an exit wound. The entrance wound is often "closed over" by the skin, when the animal moves. The expanded jhp, to exit thru skin, needs 60+ ft lbs, and if it also breaks a rib on the way out of the body, it needed another 40+ ft lbs. so if your bullet DOES exit a man, it wasted at LEAST 60,, and probaby 100+ ft lbs of its potential power. That energy is FAR better used a couple of inches shorter, still in the vitals. Nearly all pistol loads have minimal power, shouldn't be wasting any of it.
