"I would much rather go for head shots on hogs with a .22 mag than any other rimfire.".........I hope that you shoot from ten feet or so up a tree with that magnum...Head shooting a 200 lb tusker is best done with 12 ga 3 in mag 00 buck pump or auto loader.............
I have killed plenty of wild pig with 30 06, 308, and twelve gage....Killed a few with a Ruger Black Hawk 44mag 7 3/4 in barrel, but I had a back door plan before I pulled the trigger.
I ain't shooting any South Carolina wild pigs over 50 lbs with a 22 magnum that has a less than ten shot magazine or two and I am ten feet up a tree.
