Dave,
Not to get too far afield from your calibers, however, the lowly 22 LR is sufficient energy if the hog is shot in the right place (the center of the "X" between the ears and eyes below which lies the brain).
It will not require a bean-field flat shooting rifle to down a hog, just good shot placement. You should be able to get pretty close to the hogs as their eyesight is not nearly as keen as deer. Their noses and hearing are real good though.
The calibers you have produce more than enough energy. Use a steady rest and shoot them in the neck - midline or head above the upper jaw line and behind the eye. Like deer, they don't take it well in the neck and will go straight down.
