If i were a poor grad student I would buy the cheapest reliable 30.06 I could buy and a case of ammo and go kill everything that walks here. I would spend whatever money I had left and go hunting. Hunting here will cost you if you want consistently good hunting. It will most likely involve a plane or a boat. I know there are exceptions to that , but its a fair statement to say your choice of caliber from 06 and up shouldn't be your biggest concern regarding hunting here. There are much more important things to consider and plan.
