The Leupold Ballistics Aiming
System
– Boone and Crockett
Big Game Reticle
The goal of every hunter is a successful hunt with a clean harvest. It was with
this in mind that Leupold
®
created the Leupold Ballistics Aiming System
.
Because we so strongly agree with the Boone and Crockett Club’s
®
legacy of
wildlife conservation and ethical fair chase hunting, we have designated one
of the system’s reticles as the Boone and Crockett
Big Game reticle, while
the other is designated as the Varmint Hunter’s reticle.
Together, the Boone and Crockett
Big Game reticle and the Varmint Hunter’s
reticle give the hunter two very useful tools intended to bring about successful
hunts with clean and efficient harvests. Through the use of these straightforward
and easy-to-follow instructions, it is sincerely hoped that all hunters will find
their skills improved and their hunts more successful.

Leupold Ballistics Aiming System provides a series of aiming points to
improve your ability to shoot accurately at longer ranges. The first aiming
point (the intersection of the Duplex
®
reticle) is designed to be used at 200
yards with most common cartridges or at 300 yards in several flatter shooting
cartridges designed for longer range use.
The Leupold Ballistics Aiming System provides you with two different power
selector positions, indicated by large and small triangles located within the
magnification level indicators (VX
®
-7 users: see “Another Way to Sight In”
on page 30). These are provided to allow you to select the hold points best
suited to the cartridge you are using. In some cases, the smaller triangle setting
can be used to accommodate your slower, heavier bullet load, while the
larger triangle can be used to accommodate a faster, lighter bullet load in
the same rifle. The reticle assumes bullets of similar spitzer shape will be
used throughout.
An Overview of the Leupold
Ballistics Aiming System
As an example, a 30-06 with a 180 gr spitzer bullet and 2700 fps muzzle velocity
would require the use of the smaller triangle mark. A 30-06 with a 150 gr
spitzer bullet at 3000 fps muzzle velocity would use the larger triangle mark.
We have designated three sets of cartridges to be used in conjunction with
the large and small triangles and sight-in distances of either 200 or 300 yards,
described as Group A, Group B, and Group C:
Group A cartridges will use the large triangle and a 200 yard zero
Group B cartridges will use the small triangle and a 200 yard zero
Group C cartridges will use the large triangle and a 300 yard zero
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.

SIGHTING-IN
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 (Group A and
B), or 300 yards (Group C). For Group C cartridges sighted-in at 300 yards, the
lower aiming marks will be correct at 400, 500, 550, and 600 yards. 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.

The Boone and Crockett
Big Game reticle offers:
a Duplex central aiming point (sighted-in at 200 or 300 yards) as well
as CPC-style hold points calibrated to 300 and 400 yards, and additional
aiming features for targets at 450 and 500 yards for Group A and Group B
cartridges (add 100 yards for Group C cartridges)
a 10 mph windage hold point at both the left and right ends of the 300 and
400 yard CPC-style hold points
the traditional VX

-III range estimating feature between the Duplex central
aiming point and the top vertical heavy post (consult the Leupold Riflescope
Owner’s Handbook)
Specific Instructions for the
Use of the Boone and Crockett
Big Game Reticle
NOTE: When using a cartridge in Group C and sighting-in at 300 yards, add
100 yards to all of the above yardage indicators.

In order to use the Boone and Crockett
Big Game reticle, you must determine
which of the three groups (Group A, Group B, or Group C) your cartridge and
load fits into.
DETERMINE POWER SELECTOR SETTING
First, determine which of the triangles on the power selector is the correct
one to use with your particular rifle caliber, bullet weight, and muzzle velocity.
Refer to the tables of Group A, Group B, and Group C cartridges on page 4.
Using the Boone and Crockett
Big Game Reticle
Once you have determined which triangle is the correct one for your rifle caliber,
bullet weight, and muzzle velocity, always remember that is the position to which
you must set the power selector when using any of the hold points on
the Boone and Crockett
Big Game reticle.
DETERMINE THE RANGE TO THE TARGET
Determine the range to your target using a laser rangefinder such as a Leupold
RB800C, or RX
or RXB Series digital laser rangefinder, or utilize the traditional
VX-III range estimating feature using the space between the Duplex central
aiming point and the top vertical heavy post. For more information about how
to use this feature, consult your Leupold Riflescope Owner’s Handbook.
AIMING
The Boone and Crockett
Big Game reticle is a hold point reticle. For targets
judged to be 300 yards away, hold directly on the 300 yard hold point. For 350
yard targets, hold directly between the 300 and 400 yard hold points. For your
convenience, a 450 yard hold point has been included between the 400 and
500 yard hold points.

WIND COMPENSATION
The left and right edges of the 300 and 400 yard hold points may be used as
10 mph wind compensators. To correct for a wind speed of 10 mph, place the
edge of the hold point for the appropriate distance directly on the target when
aiming.
CONCLUSION
• Choose the appropriate ballistics group
Sight-in at the distance required by that group (this may be done at any
magnification setting)
Adjust the magnification to the appropriate triangle before using any of the
long range hold or windage points

Varmint Hunter’s Reticle
The goal of every hunter is a successful hunt with a cleanly made harvest.
Whether a hunter is pursuing big game or varmints, it is imperative that he or
she strive to make a quick, humane kill. It is with this in mind that Leupold has
introduced the Varmint Hunter’s reticle, a tool intended to allow shooters to
make solid hits and clean kills at longer ranges on varmints.
Together, the Boone and Crockett
Big Game reticle and the Varmint Hunter’s
reticle give the hunter two very useful tools intended to bring about successful
hunts with clean and efficient harvests. Through the use of these straightforward
and easy-to-follow instructions, it is sincerely hoped that all hunters will find
their skills improved and their hunts more successful.

An Overview of the Leupold
Ballistics Aiming System
The Leupold Ballistics Aiming System provides a series of aiming points to
improve your ability to shoot accurately at longer ranges. The first aiming
point (the intersection of the German #4 reticle) is designed to be used at 200
yards with most common varmint cartridges or at 300 yards in several flatter
shooting cartridges designed for longer range use. See page 14 for cartridge
group tables.
The Leupold Ballistics Aiming System provides you with two different power
selector positions, indicated by large and small triangles located within the
magnification level indicators (VX-7 users: see “Another Way to Sight In”
on page 30). These are provided to allow you to select the hold points best
suited to the cartridge you are using. In some cases, the smaller triangle setting
can be used to accommodate your slower, heavier bullet load, while the larger
triangle can be used to accommodate a faster, lighter bullet load in the same
rifle. The reticle assumes bullets of similar spitzer shape will be used throughout.
As an example, a .223 Remington with a 40 gr V-max
®
bullet and 3800 fps
muzzle velocity would require the use of the larger triangle mark. A .223
Remington with a 55 gr V-max bullet at 3240 fps muzzle velocity would use
the smaller triangle mark. We have designated three sets of cartridges to be
used in conjunction with the large and small triangles and sight-in distances
of 200 yards, described as Group A, Group B, and Group C.
• Group A cartridges will use the large triangle and a 200 yard zero
• Group B cartridges will use the small triangle and a 200 yard zero
Group C cartridges will use the large triangle and a 300 yard zero
