Bushnell 204100/204101 manual Regular Mode, Knowing Which Ballistic Group to Select

If in RIFLE mode, the ballistic group will be displayed in the bullet drop numeric field anytime that the primary numeric display is showing dashes (i.e. no target acquired). When a target is acquired in RIFLE mode, the line of sight distance will display in the secondary numeric displays. The “IN” icon (i.e. inches) will light next to the bullet drop numeric display, if the unit of measure is set to Yards (Y). If the unit of measure is set to Meters (M), the bullet drop will be calculated and displayed in centimeters and the “IN” icon will be turned off. If the bullet drop / hold over number is blinking, this means the user should add 100 to the number blinking.

Regular Mode

This mode does not provide any degree of elevation or compensated distance, but instead, line of sight distance only. The will still appear below the line of sight numeric display, but there will not be any information displayed in this secondary numeric display.

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. For Muzzleloaders, we have worked with PowerBelt Bullets to incorporate ballistic data into two ballistic groups (I and J).
