The pictures I've seen of arrow wounds suggest an arrow through the center of mass will cut a hole 1 to 1-1/2 inches diameter and pretty well through and through. A pistol bullet wound probably is much smaller and has less penetration. I think it's likely a victim could survive a single bullet wound, assuming nothing vital was hit.(brain, heart, major vessel) An arrow wound could easily bleed out before effective hemostasis could be achieved.
