If you are looking at a Nikon Monarch, check out the BDC reticle.
Also Nikon's Spot On Ballistic Match Technology Program will help you really dial in your shooting distances. Go to Nikonhunting.com, click on the Spot On logo and register, it's all Free, then you'll be directed to the Spot On site.
