I am against head shots as well. I think at least some of it is caused by some who want to use minimal calibers and feel they are doing something "special" by killing a large animal with a small caliber & bullet to the head. Call me old fashioned, but not one thing impressive doing that IMHO.
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.
As far as neck shots are concerned, I do make them when presented at a good range. My "neck" shots, however, are base of the neck shots which normally makes for DIT hits and recoveries. My last hog was a neck shot at 125 yds and worked as they always do. Of course a hog doesn't really have much of a neck either....lol.
