I have blasted hogs with just about every caliber from .22 mag to 30-06. I think the hog is WAY over rated when it comes to trying to kill it. They go down very easy with a good shot to the chest. Slugs, 22-250, 6mm, 25-06, 30-30, 30-06 killed them all with only one in myrecollection running more than 2 feet. I think the 2 feet they went was from their legs folding and them falling to the front. You do not even need a huge caliber to penetrate their shield of the males. My buddys go to hog gun is his 22-250. It absolutely liquifies the internals on big boar hogs and he is shooting a little bitty 55 grain bullet. My go to gun is my 30-06 and more often than not I am shooting completely through the hog including the last 180 pound boar. Shoot what ya like and go get some bacon.
