Many people feel completely comfortable shooting a walking deer with shotguns. Heres some figures. At 20 yds (comfortable forbowhunters)an arrow moving at 300 fps will hit the deer in 0.2 seconds. At 75 yds
(a comfortable range for many hunters) a shotgun slug moving 1000 fps will hit the deer in 0.225 seconds. At a walking deer the projectile reaches the deer with my bow in my comfort zone around the same as with a shotgun. My bow is just a tad quieter than my 12guage though. FPS isnt exact but around the same ballpark
