So I'm finally getting around to mounting my leupold 6.5 x 20 x 56 scope on my model 12 savage in 204 ruger. So I looking for a recommendation on MOA scope base if I should go with a 0,5,10 etc. It is only a 204 ruger so I think I won't shoot over 400 yards and the scope has 90 moa of vertical adjustment.
