I can't help you with your question because I live in North Carolina.
But I have killed a lot of wild hogs. It is the best meat on God's green earth.
I would let an 8 pointer walk, if it meant I could shoot a 150 pound sow.
You don't need slugs, any good deer rifle will lay waste to Mr. Pig.
Get one of those smokers, the metal ones about three feet high, and fifteen inches wide, with a little electric element and a plate to put wood chips on, and a bowl to put liquid in to keep the meat moist.
Salt and pepper that wild hog ham, put mesquite in the smoker, and fill the bowl with red wine, or else beer.
Sit around drinking beer for 8 hours while that thing smokes, best eating in the world.
