There aren't many regulations on hogs as they aren't a "game" animal. You hunt them any way you please with a few exceptions.
Must get a permit from warden to hunt them at night
No buckshot. Slug or BB and smaller for shotguns.
Must follow rules of wearing orange during big game rifle seasons and you either need a filled or unfilled deer tag if you are hunting them with a rifle bigger than a .22 rimfire during deer rifle season.
I might have missed something....if so, the others will chime in.
They are throughout the state and if you have them, you will know it. They leave a mess of where they have been.
I believe he is correct on everything but the buckshot part. If you are on private land, there is no restriction on shot size.
"The pursuit of feral hogs with a shotgun on private property is not restricted by shot size."
WMA's vary, so check regs before you go slingin your shotgun full of 00 out there during rifle season. That is sure to get you a GW signature.
