no, whle the pneumothorax collapse of the lung is an aid to a swifter kill on the animal, it's not fast enough to help you in a gun fight. Anyone can hold their breath for 30 seconds, and anyone can shoot you 4x per second. The blood trail, so useful to us for finding the dead critter, is of no advantage in a defensive fight

If, instead of 12" of penetration (ie, exit wound) and a transferred 300 ft lbs of power to the man, I could get 2 wound tracks (bullet split lengthwise, segments tumble) 600 ft lbs of power and have the bullet stop in the man, same load, same recoil, but could "only" get 6" of penetration, I"d take that performance in a heartbeat over the 100% greater penetration. Cause my way is easily proven to offer a much greater likelihood of the required instant stop
