I think the rifle choice can also be dictated by where you hunt. If you are hunting in thick forest where a 100 yd shot is the max, you may be able to get away with a 30-30. If you anticipate making a longer shot you probably want to go with the 30-06. I've used both, and both will take a deer down quick. Factory ammo in the 30-30 is a little cheaper than the 30-06.
