The Bushnell 2--6x will allow the versatility to use 2x if you are close and slip it to 6x if you need to concentrate on 200yds. The one I have allows you to ''index'' the zero point. Loosen the tiny screw in the turret and lift it. Index the tiny pointer to 6oclock and replace the tiny screw. Now if you have zeroed at 100yds for example, you only need to add clicks to get to 150 or 200 when you need them. Add this info to your notebook.
