Can't say about pigs, as I don't have any here to hunt, but I've shot a lot of 85 grain Sierra HPBT's at coyotes and they work great. I'm loading them at 3250-3300 fps. My other two favorite coyote bullets are the 58 grain VMax and the 65 grain Berger. These will flat give a coyote a dirt nap in a second.
