Knowing Which Ballistic Group To Select
Bushnell engineers have researched currently available ballistic data and grouped many of the most popular calibers and
loads into eight ballistic groups (A, B, C, D, E, F, G, H). Once you know what caliber and load you are shooting, look through
the chart to determine which one of the eight ballistic groups matches your particular load and caliber. For Muzzleloaders,
we have worked with PowerBelt Bullets to incorporate ballistic data into two ballistic groups (I and J). Below are a few of
the most popular caliber/load combinations. A complete list of 2000 caliber and load combinations is on Bushnell's
website (www.bushnell.com).

After you have determined which ballistic group corresponds to your caliber and load, select this ballistic group letter
along with Rifle mode. The internal formula will determine the amount of bullet drop/holdover in inches or centimeters
based on your caliber and load's distance, angle, and ballistics.
What if my caliber/load 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 developing. Also, some shooters load their ammunition with unique ballistic characteristics. If you cannot find
your load in our ballistic tables, you can still use the laser rangefinder bullet drop feature. 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 are shooting long distances, 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.
After you have confirmed your selection of Rifle mode with the ballistic group you need (by pressing the Fire button
while it appears in the display), the next item is the Unit of Measure option (13). Pressing the Mode button will toggle the
Units from the default "Y" (yards) to "M" (meters). Press the Fire button to confirm your selection (leave units set to Yards
or change it to metric).
Next, you will see "SD," meaning Sight-In Distance. Briefly pressing the Mode button will cycle through a choice of
100, 150, 200, or 300 yards. Press the Fire button to confirm and save the setting when your preferred sight-in distance
is displayed.
