I think that you would be able to find a used Remington 700 bolt action in the 270-30-06 range for about $300. Then you could puta nice Leupold VXI 2-7x33 scope on it for about another $200 including the rings. That puts you at the $500 mark. This will leave you enough money left over for a nice sling, and some ammunition to practice with. That is what I would do.
