The Leupold Ballistic 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 Ballistic 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.

The Leupold Ballistic 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 Ballistic Aiming System provides you with two different power

selector positions, indicated by large and small triangles located within the

magnification level indicators. 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

Ballistic Aiming System

L245-0685C_BAS_Inst_Man.indd 2 10/6/05 10:13:19 AM

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. Ballistic 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.

General Instructions

For the Use of the Leupold

Ballistic Aiming System

SIGHTING-IN

The Boone and Crocket

™

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. Be sure to verify

the aiming points by practicing at the actual distances at which the points are

intended to work. Ballistic 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)
