I'm always curious to see what calibers other people have chosen to hunt with. For a totally unscientific sampling, my mates (to use the Aussie term) in the US south used these during the last season:

243, 6.5x55 Swede, 7mm-08, 270, 300 Win Mag, 35 Whelen plus one guy who only hunts deer with his favorite 44 Magnum lever action.
