I voted for the .308 but I can't think that for hogs under 300 pounds that it makes any difference. We normally hunt hogs from towers in South Texas and as long as a rifle can reach out to 200 yards with authority that's good enough. There are any number of calibers that can do that. When it comes right down to it, I'll pack a .243 over either the .308 or the .270. I've also taken a number of hogs with the .25-06 and even the lowly .30-30.
