Neck shots can be quick killers or stunners or bad wounds.I have seen three deer drop at the shot after being hit in the neck only to jump up and run away.Two had to be shot a second time and the last was found after a long tracking job.Anyhit near the spine will usually stun a deer but they are not always lethal,and since the spineand neck are such small targets I usuallyavoid them altogether and prefertake much higher percentage lung shots.
