I've only been one hog hunt, in Florida, so for what it's worth, my 2 cents. I used my Tikka T3 stainless .270win with Leupold vx-2 3-9x40. Dad carried his trusty old Winchester in .32 special. Dad had been hunting since he was 12, me, not so much. I hit a standing hog. He ran a ways and dropped. Dad hit a running hog from a moving 4 wheeler buggy at about 30 -40 yards, in the spine I guess cuz after he was hit only his front legs worked. One more shot to finish it. Mind you, Dad was 80 at the time. I got another, standing, in the front shoulder, about 80 yards. He turned toward me and fan at me along the fence line. Second round startled him but he kept coming. The last one went in his mouth and out his hind quarter and he dropped. All my rounds were clean through. I tell this story to pass along Dad's advice- bullet too small, moving too fast.
I think on the next hunt I'll take this CZ527M carbine in 7.62x39 and see what happens. Unless I decide on a semiauto, which will be a Springfield M1A.
Hope this helps.
