Hello, Years ago, my son and I would hunt with muzzleloaders but now I'd like to start using a centerfire rifle. I am sure this has been asked many times before--what would be some of the better rounds for hunting deer in the forested areas of Western Oregon. I'm looking to make shots between 30 and 100 yards. I am thinking a 30-06 would be overkill for this type of hunting. Any recommendations? Thanks!
