I use to manage a substantial amount of citrus acres in FL with serious hog problems. I always shot them in the head with a 223 and drop them in their tracks. The only ones that ran were then ones I shot running and they just did a nose plow into the ground which was the result of their forward momentum. Same results no matter the yardage.
Very little blood trail, no tracking and no wasted meat...........unless you know how to make hog head cheese. LOL
