The Leupold Ballistics
Aiming System –
Long Range Duplex Reticle
To use the Long Range Duplex reticle, zero your rifle at either 200 yards for
Group A cartridges or at 300 yards if your rifle is chambered for one of the
Group C cartridges from the Long Range Duplex table on page 22. 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. If you are using a Group C
cartridge, this will make the dots below the crosswire be zeroed for 400, 500,
and 600 yards. The scope must then be set to its highest magnification setting
to properly use the ballistics compensating features.
