People have underestimated the toughness and tenacity of wild hogs for many years falcon. While I am far from against the use of a PRB, you HAVE to know their limitations on penetration. I have seen a few of the hogs from your area that Jon posted up on here and can tell you that your winter hogs have a good bit of fat on them. You add that heavy fat layer up with that tough as hard tack leather shield and you have some serious protection of the vitals. Even with a big ole ball from a .54 loaded up you shouldn't shoot past 50 yards on a healthy 150# boar hog. That heavy protection will flatten out a PRB and while yes it will still most likely be lethal, the terminal performance of it will be severely limited. Hydrostatic shock will be dang near nullified since most of it will be spread throughout the fat layer. I've seen heavy winter hogs do the exact same thing after being hit perfectly behind the shoulder with well penetrating .30 caliber center fires.
