You cant go wrong with anything that has been mentioned so far. Although I am not sure if a person could afford to fire that 50BMG too many times in a day and if you are looking to keep the pelt you may want to go with something just a lil' smaller in caliber lol. I really dont see how you could go wrong with with a .243 though. Cheap ammo, good selection of rifles out there and a pretty accurate round.
