Don't leave out the option of a used rifle. There are often great buys in good used hunting rifles. I would suggest a bolt action in 30 cal. .... something like a 30.06 Spr. or 308 Win. will do great for deer. A 270 Win. is a great choice too. I would not pay extra for a wood stock. Composite stock will do fine. Save room in your $600 for decent scope if at all possible.
