There are none for hogs but are for deer. Hogs are a "Shoot on Sight" thing. The regulations on deer are fairly straight forword. Shotguns with slugs, rifles and pistols above .25 cal., no rimfires. Blackpowder during firearms season or during the special blackpowder only hunts. Magazine capacities on rifles and handguns cannot exceed 10. You can go to the MO. conservation website for more detailed info.
