. Shooting ability has every thing to do with it and confiedence.
Well said,and every hunter should be able to make these shots on a TARGET.
Aiming for a small white patch on his throat from 15 yards away when the deer is about to run and your addrenalin is pumping dosn't make for a favorable shot,to many variables.Especially if you miss the "patch" and hit his shoulder blades.Thats where the poundage and broadhead comes into play,without enough K.E pushing a good broadhead into his vitals you are asking for alot of trouble.
And about the straight down spine shots,no way.Miss the spine and maybe hit one lung,long blood trail,assuming the arrow passed through.If not it will be a long night waiting on the deer to expire and hoping to find him in the morn nearby.Like Priz said,we owe the animal more ,and treat it with a little respect.We dont want the animal to suffer due to unethecal shots.It happens in the field everyday,but we can sure prevent them with a little common sence.
