Well a deer is less likely to feel an arrow pass through his lungs than a bullet. The arrow slices with razor blades and they seldom feel it. you ever cut yourself with a razorblade ? It takes a little while before you even notice it. A gun shot kills with a lot of force ( Shock ) They say a gunshot is painfull. They both die very sudden though, when both are placed in the vitals. You know there are no nerve endings in the lung tissue ? Your lungs cannot hurt, nor your brain.
