Deer certainly have variable reactions to being shot. My father put an early 130 gr Bal Tip through the chest of one. It was relatively close, about 125 yards if memory serves, and the launcher was a 26" barreled 270 with a case full of H4831. If you saw the carcass before the blood trail you probably would have bet $10000 that it dropped at the shot. You would have lost, it traveled a fair distance.
