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.

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)

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
