If I lived in a state that didn't allow hunting with a rifle, and allowed a revolver, I would seriously look at a .500, or the new .460 SW Mag (Interesting, but kinda superfulous maybe). It would give them a bunch of knock-down and range, almost to a rifle, and be easier to tote around than a shotty. Some people just like them, which is about as viable an option as anything. Same crowd who goes after the desert eagle in .50AE. Personally, I would be happy with a revolver that fired .45 long colt, because most of the time I would be shooting .45 acp out of it, but if I ever needed more power, I could just throw some .45 LC into it and have about enough punch for what Id be doing (and not have 9 inches of barrel.
