Once you get the hang of it it is easy to bang flop a hog with a .22 LR. Limit your shots to 40 yards orless and onlyshoot at a hog that presents a side view. Shoot the hog in the ear, in the eye or ona line between the ear and the eye. As long as the hog is kicking keep shooting him/her in the head:A semi-automatic is good for that. Do not use hollow point bullets, you want penetration.

The .22 magnum is a fine hog killer. I use the CCI full metal jacket bullets. That bullet will go all the way through a 100 pound hog shot low behind the shoulder. Never had a hog get away after being shotwith either a .22 LR or a .22 magnum.
