I've seen video of this "professional hunter" on versus kill them with a pellet rifle. That was with in ten yards and he had hounds and a back up guy with a 30-30.

Would I personally hunt them with a 22lr. NOPE. It can be done. Personally I would not try it because I have other options and have no experience yet in hunting hogs. I'm hoping my first trip to be in the next three to five years and to do it with my bow or my 44mag rifle. If you have previous experience with them, and I assume you do. Then you very well may have the experience needed. I wish ya the best of luck either way.
