I am NOT a bow hunter but a few years back was watching a hunting show where I guy shot a grazing buck around 30 yards. It was a clean pass through behind the shoulders through the lungs. The buck jerked his head up looked around then went back to feeding. You could see the blood running down his side. After about 30 seconds he started swaying, took a few steps and collapsed. At the shot, never really reacted to flee, just went back to eating. Damndest thing I ever saw.
