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 amount of bullet drop/holdover in inches or centimeters
based upon distance, angle, and ballistics of your caliber and load.
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 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.
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.
Lastly, you will have a choice of formats for the bullet drop/holdover data that will appear in the secondary numeric
display (14): IN (inches)*, ML (Mils) or MOA (moa). Briefly press the Mode switch to cycle through the 3 options, pressing
the Fire button to confirm and save the setting when your preferred bullet drop format is displayed. *Note: if the unit of
measure was set to Meters (M), the bullet drop will be calculated and displayed in CM (centimeters) rather than inches.
Rifle Mode Example
Line of sight is 376 yards, angle is -33 degrees, and the bullet-drop/holdover is 28 inches. ARC not only takes into
account ballistic data based off your caliber and load from distances of 100-800 yards, but also compensates for any
uphill and downhill angles which also affect bullet-drop.
The Prime rangefinder’s 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.
