Im going to be in the market for a scope for my Winchester 70 .308. I really want to keep the cost under $250. I would prefer the scope to be in the 4-12 x 40 range. Right now the three that I have in mind is a Bushnell Elite 3200, Nikon Prostaff, or a Redfield. Anyone have experienc with these? Right now I am leaning towards the Redfield.
