Most of the hogs I've shot have been with a .300 Win Mag, mainly for the extra reach. The country I hunt is pretty open, and we try to catchthem coming across the fields in the morning. Also, that rifle was the only suitable one I had at the time. I would feel comfortable using my .30-06 or .270 with a good, non-premium bullet like a Hornady Interlock or even a Remington Corelokt. I've seen them taken with everything from a .22 Mag to a .45-70, and the worst were the couple shot with .30-30's, although I have to say that shot placement by those hunters was poor and they required me to finish them off. They were hit too far back, and anything short of a .50 BMG would have required follow-up. So I can't really blame the cartridge.
