Texas Tom,
I was born and raised in south central Lousiaina shooting and eating wild feral hogs. I have shot them with everyting from a .22 rifle to my .264 Win. Mag. and a shotgun with squirrel shot. The best shot, depending upon the shot angle is: 1) in the ear hole, 2) behind the ear, 3) thru the eye, or 4) in the neck at the base of the skull. If you shoot a boar, especially an old boar, in the shoulder - It just [beeep] him off. The old boars have a "fighting pad" protecting the shoulder and front rib area...Takes a good bullet to penetrate this pad. The meat(sow) is delicious and the fat is not marbled in the meat...it is on the outside. The meat is lean and dark red. Now if you kill a boar, leave it for the coyotes and now you have a "baited" spot. I have just moved to the North Texas(Borger) area and know quite a lot about hunting or trapping hogs. Do you need any help?
