A used remington 788 in .308. Probably run you 300 bucks for a good condition one. Top that off with a Leupold 3X9 VX1 scope. total cost 500.00

If I were to buy one new today, I would pick up a remington 700 ADL/CDL in 300 win Mag. Top off with the same leupold scope. That outfit would still be around 550.00
