I see no problem what so ever. If one desires an animal he otherwise could not hunt on his own.....go for it. You still have to hunt it and kill it.
Like your thought of handgun for pigs as I've always wanted to do that myself.
BTW, someone has just opened a hunting preserve here in Warren, Oh. It's on the corner of Rtes. 11 and 82. Sorry, can't remember the name off hand. Also the prices are quite high.
Good luck in whatever you choose, Daniel. We're getting to that age where opportunities are becoming rare.
