You cannot go wrong with a remington model 700 .308 (for loooong ranges go with the PSS model)....it will do a number on theground haawgs and mess up a yote to boot. With a heavy grain round you can drill em at 800+ yards. The pic is a modified .308 rem 700...but you can still do great with an off the shelf PSS.
Check here for specials (they are reasonable).....
