"Those who have done a lot of deer hunting also realize that a deer moves it's head a lot. Even an expert shot cannot always anticipate when a deer is going to move it's head. A shot at that moment may leave the deer with a crippling injury that leads to a long and painful death. Not sportsmanlike in my book." Well said Turner!
Have never tried a head shot, and never will, just for the reason mentioned by Turner.
Have tried one neck shot, and that was with a .30/30.
Nice 8 pt walked out of the brush ~ 50 yards away and then stopped.
I'll admit I got "buck fever" and put the first round high.
Buck froze, much to my surprise, instead of bolting.
Jacked a second round into the chamber, and took an extra second or two to get my breathing and adrenaline under control, then squeezed the trigger.
Buck took two steps and dropped.
But now I'm back to lung/heart region, preferring double lung shots.
They may run, but they won't run very far.
Most I've had one run with a double lung shot is 35-40 yards.
