Two years ago I shot a deer at a fairly steep angle quartering slightly forward (not my best shot selection, admittedly). I had good blood, followed it for 100 yards and it stopped immediately. I wound up finding her another 150 yards away, with a lot of luck. The shot entered behind the shoulder, got one lung, liver, through diaphram and out low behind last rib. Didn't get guts, but exited around the abdomen. A small part of in-tact intestine had come through the exit wound (2" rage) and completely plugged the hole and stopped the blood flow. Just as dead, but impossible to track after the hole got plugged.
