Allen Day told me that before my first trip to Africa and at least in my experience, he was spot on. I used to go for the double lung shot on game and yes they all died, but they ran a ways. When I switched to the central shoulder shot, animals if they ran, didn't go very far.
If you hunt in places where an animal can run 200 yards before it dies, and there are inaccessible-to-you locations within that radius, lung shots are less likely to put meat in your freezer and horns on your wall than shoulder-heart shots, in my experience.
