I' ve done both.

I have killed more deer with a bow than with a gun. But I' ve also spent more time with a bow to accomplish that. I have a very difficult time hitting a running deer with a gun, and a real easy time shooting a standing still deer at 15yds with a bow.

If I was given a choice between sitting in a tree all day with my bow and having all day to put on 2 man drives with a gun, and it was kill a deer or else......My butt is going to be carrying the gun.
