Heavy, fat, slow does the trick again.
That’s why my woods gun is a P220 45 with extended mag.
Watched an old boy dump 8 rounds from a Springfield 45 into a 265 lb boar, no round made it to the vitals. Two years later I shot #8 (Nick name) and he had 1 round in his neck 6 in his shoulder area and one in the left hindquarter. If you chose to carry a 45 in area’s where a hog might be encountered I suggest using FMJ’s for max penetration. I carry a 5 1/2 inch Ruger Blackhawk convertible in 45 ACP/45 Long Colt. I leave the ACP cylinder at the house and use the 45 LC loaded with 300 grain hardcast lead running about 1400 fps. That load will easily penetrate the shield on large hog’s with about 1300 ftlbs of energy.
That would work on a small 150lb hog, but not on some of the ones I see around here unless you hit him square in the head. A big male boar has some pretty thick and tough shoulder plates, and it's a long way to the vitals.
