my vls in 308 wears a leupold 8.5-25x50, 30mm tube, and all the other bells and whistles. perhaps a little (lot?) overkill for 300 and in shooting, but for when you decide to start to stretch the range, you won't be limited by the scope.
if i was absolutely certain i'd never shoot beyond 300 yards, then a leupold 4-12 vx-2 would do just fine.
but, i really enjoy prairie doggin', especially long range doggin', thus the big scope.
