I want something accurate and powerful.
I have posted about my hog hunting rig before which is a G20 with Ameriglo ghost ring night sights. I shoot 220 hard cast Buffalo Bore... which is somewhere about 700 ft lbs.
45 Super would be another choice.
With hogs, don't use JHP. You want to penetrate their thick hide and not make them mad and just wound them.
I don't want to be cornered by 300 pounds of angry bacon.
