First of all, your uncles arn't wrong about the .30-'06. It will do pretty much whatever you need here in NA. The .308 is pretty much a short action version of the '06, and would be my first choice for a new hunter that doesn't reload. Tons of ammo availible, less recoil than the '06. To be honest, anything from 7mm-08 up through .30-'06 will do the job. I'd be more worried about finding a rilfe that fits you well and feels good, than the round it's chambered for. Make sure you gat the scope mounted low enough to alow a good cheek weld on the comb of the stock. Good stock fit goes a long way toward maximizing your accuracy potential and really helps minimize felt recoil.
