Sound like a Nightforce maybe a great way to go for you but I'm not sure if they will be out of the price range. Also I would recommend looking at the getting on with the NEW High Speed 0-Stop turret. For a lower cost unit the Leupold VX-III or the MARK 4.
It maybe best if we talk over the phone for I maybe able to help you a little faster that way.
Thanks for asking us and I hope we can be of help.
