Controversial? to who?, Ive hit it and from that looks of things so have you. That sucks, I hit a doe about 15 years ago like that she stood there and looked at me with the arrow sticking out of both sides of her chest. Followed a very sparce blood trail for about 300 yards and that deer never bedded down or slowed down. The anatomy chart shows a deer with fully expanded lungs, imagine what happens when the deer breaths out.
