Some deer do, but, you can not bank on it. So what you want is double lung. If you get heart and lungs, all the better, but, the heart is a very small target compared to the size of lungs. And as Ralph says over and over again, Quartering away, behind the shoulder and aim for your arrow to hit the opposite front leg. Double lung every time and he ain't going far!!!! Always aim for where your arrow will exit.
Get outdoors and discover the world around you!!!!!
