Bushnell 20-5101 Knowing Which Ballistic Group to Select, Popular Caliber & Load Combinations

Once in this mode, press the POWER button to turn the unit on. Next, align the aiming circle onto the object that you want distance to. Next, press and hold the POWER button and move the laser slowly over the object until a circle surrounds the Brush indicator. If the laser beam recognized more than one object (i.e. close-up tree branch and a deer in the background), distance of the further object (i.e. deer) will be displayed and a circle will surround the brush indicator informing the user that distance to the farther object is being displayed in the LCD (as seen below). There may be times when only the laser beam only sees one object in its path. In this case, the distance will be displayed, but because more than one object was not acquired, the circle will not surround the Brush indicator.

TIP: While pressing the POWER button, you can move the device slowly from object to object and intentionally force the laser to hit multiple objects to ensure that you are only displaying the furthest of the objects recognized by the laser.

Once the device has shut off, the unit will always default back to the last targeting mode used.

KNOWING WHICH BALLISTIC GROUP TO SELECT

Bushnell engineers have worked with Sierra® Bullets’ ballistic programs 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 simply look through the chart to determine which one of the eight ballistic groups match with your particular load and caliber.
