Bushnell Elite 1 Mile ARC CONX Manual page 18

After you have determined which ballistic group corresponds to your caliber and load, select this ballistic group (See
MENU SETUP above). The internal formula will determine amount of bullet drop/holdover in inches or centimeters
based upon distance, angle, and ballistics of your caliber and load.
This state-of-the-art digital technology allows the hunter or shooter to know precisely where to hold for an effective
shot. This information should be treated as a helpful guide or tool and in no way should it ever replace practice and
familiarity with your rifle, cartridge and load. We encourage practice shooting at different ranges so you know how
your rifle, cartridge and load will perform under various conditions. Always know what is behind your bullet; if you
don't know, don't take the shot.
EXAMPLE
You have a 300 WSM and are shooting the following Winchester brand load: 180 gr. Ballistic Silver Tip bullet at 3010
FPS muzzle velocity. This combination falls under Ballistic Group "F". After setting the rangefinder to ballistic group
"F", go to the range and sight in your riflescope at 100 yards. If you then take a shot at a target at 317 yds, the bullet
drop will be 9 inches. If the shot is at angle of 27 degrees upward, then the corrected bullet drop will be 8 inches.
