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.
WHAT IF YOUR CALIBER IS NOT LISTED?
While we have taken great care to include as many calibers and brand names in our ballistics tables, new loads are
always being developed. In addition, some shooters load their own ammunition with unique ballistic characteristics.
If you cannot find your load in our ballistic tables, you can still use the bullet drop feature of the laser rangefinder. As
above, sight in your rifle at 100 yds. Then shoot the rifle, without adjusting the riflescope, at 300 yds. Measure the
bullet drop from the point of aim. Using this drop, select the ballistic group from below. If you will be shooting longer
distances then you may want to check the bullet drop at 500 yds. Because there is enormous variation in rifle barrels,
chambers, and hand loads, you should thoroughly test the ballistic setting before actual hunting. You may need to
move up or down one group depending upon your tests.
