Leupold & Stevens, Inc., worked with a diverse, highly skilled group
of hunters and shooters to develop the new Ballistics Aiming System,
which includes the Boone and Crockett
™
Big Game reticle, the Varmint
Hunter’s reticle, the Long Range Duplex reticle, and the Long Range
Varmint reticle. Special thanks to: outdoor writer, ballistics consultant,
and lifelong varmint hunter Steve Timm; the Boone and Crockett
Club
®
staff; Tim Lesser, antelope, deer, elk and varmint guide, and
Marketing Communication Specialist; and Laura Peter, who holds
several silhouette shooting championships, including the 2002 British
Columbia Provincial High Power Championship, the 2002 Bronze
Medal from the IMSSU World Championships, the 2002 Woman High
Power Champion from the U.S. Nationals, the 2003 Alberta Provincial
High Power Championship, the 2004 Gold Medal from the World High
Power Silhouette Woman Championships, and the 2005 Canadian
Silhouette High Power Rifle Championship. Tim and Laura are both
valued employees of Leupold & Stevens, Inc. Again, thanks to each of
you, and the entire Ballistics Aiming System development team, for
your efforts. They have truly paid off.

Big Game, Varmint Hunter’s,
Long Range Duplex, and Long Range Varmint reticles. If you are
using a Long Range Duplex or Long Range Varmint reticle with
a cartridge from the Group B cartridge chart, or if you have
a cartridge that does not appear in one of the accompanying
cartridge charts, the following method will provide you with a
quick and easy way to sight-in. VX-7 users without large or small
triangle reference marks should also use this method.
1. Initially, sight-in at 200 yards (183 meters). Your point of
impact needs to match your point of aim exactly at the
200 yard (183 meter) intersection of the reticle.
2.
Using a larger target, place the target at a 500 yard
(457 meter) distance and shoot a group while aiming with
the 200 yard (183 meter) intersection; your bullets will strike
significantly [in some instances 60 inches (152 cm) or more]
below the center.
3.
Using a black marker, circle the group of bullet holes and fill in
the circle. This will create a large black dot representing the bullet
impact on the target that should be visible from the firing line.
4. While maintaining the same point of aim [hold in the center of
the target with the 200 yard (183 meter) intersection] adjust the
magnification setting until the 500 yard (457 meter) holdover
points in the middle of the large black dot created with the black
marker. This will create a situation where the scope is dead on
at 200 yards (183 meters) and at 500 yards (457 meters). Any
variances at 300, 400, and 450 yards (274, 366, and 411 meters)
will be quite negligible.
In order to use any of the hold points accurately, the scope will
need to be used on the exact magnification used to align the
500 yard (457 meter) mark with the center of the black dot. VX-7
users can align the notch in the ballistics indicator ring with the
witness mark on the eyepiece to allow fast and accurate return to
this setting in the field. For best results, check all aiming points at
the actual distances for which they are intended.
