The Leupold Ballistics Aiming System –
Long Range Duplex Reticle
To use the Long Range Duplex reticle, zero your rifle at either
200 yards (183 meters) for Group A cartridges or at 300 yards (274
meters) if your rifle is chambered for one of the Group C cartridges
from the Long Range Duplex table below. If you are using a Group
A cartridge, this will make the dots below the horizontal crosswire
be zeroed for 300, 400, and 500 yards (274, 366, and 457 meters).
If you are using a Group C cartridge, this will make the dots below
the crosswire be zeroed for 400, 500, and 600 yards (366, 457, and
549 meters). The scope must then be set to its highest magnification
setting to properly use the ballistics compensating features.
