UnforgivenII--
Although I happen to be the man that
Johnny Guest alluded to when he mentioned that a hog
could, technically, be taken with a .22 Hornet, it was a stunt, and I freely acknowledge the fact. (I also thought that the 200 lb sow I popped behind the ear at 80 yards at dusk was a little closer and a lot smaller!) It was illustrative, however, how vulnerable that spot behind the ear is. My little 45gr bullet smacked her about 2" or 3" behind the left ear from about 7 or 8 o'clock, and she rolled right over. (She had, as Rich says, "posed" for me for a moment.)
So,
could it, technically, be done with a .223? Sure, under controlled conditions. But why not use this oportunity to get a .50 upper, pop a hog or two with it, and come back with a range report for us. Remember to take pictures!!!
