General Instructions For the Use of the
Leupold Ballistics Aiming System
The Boone and Crockett
™
Big Game reticle is sighted-in by
zeroing the rifle at the intersection of the Duplex
®
reticle at either
200 yards (183 meters) [Group A and B], or 300 yards (274 meters)
[Group C]. For Group C cartridges sighted-in at 300 yards (274 meters),
the lower aiming marks will be correct at 400, 500, 550, and 600
yards (366, 457, 503, and 549 meters). The scope must then be set to
the appropriate triangle to properly use the ballistics compensation
features. Be sure to verify the aiming points by practicing at the
actual distances at which the points are intended to work. Ballistics
performance of your rifle and cartridge can vary somewhat from
ammunition manufacturer data due to rifle barrel length, actual
ammunition performance, and various atmospheric conditions. See
the Owner’s Manual for detailed sighting-in instructions.
