Never hunted a hog. I have a friend that killed quite a few black bear with a .243 and he used Nosler partition bullets. Numerous videos of people shooting Hogs with .223 caliber rifles on youtube. Best bet is to ask someone that hunts hogs and find out what they use. Myself, if it was a big hog, I would opt to use my Marlin 35 Remington. It makes a big hole!
