Need to do some more research. First do you have a place to hunt ? If your just starting out even in a state that allows rife deer hunting(Illinois doe's Not) don't think the Ar is your best choice. 12 ga or 308 its all shot placement, both are very deadly to deer. Where did you read 308 was to small in Illinois ? Any state that has rifle season the 308 is allowed and is a great round for deer. Please go back and read The digest before you go any further..........
