Kind of depends on what size the hog is and how far you are shooting, location?
I prefer my AR 15 in .223 for quick head shots for anything up to 150-170lb.
If you are going after bigger hog or Russians I would say the 300 out of those for killzone shots.
My personal favorite for night hunting short range is 45/70 and for longer range day hunts is 25-06.
