Applied Ballistics Glossary of Terms
Shooting Solution Fields
DOF: The direction of fire, with north at 0 degrees and east at 90 degrees. Input field.
TIP: You can use the compass to set this value by pointing the top of the device toward the direction of
fire. The current compass value appears in the DOF field. You can press START to use this value. You can
manually enter a value by pressing DOWN or UP.
NOTE: The DOF is used only for calculating the Coriolis effect. If you are shooting at a target less than 1,000
yards away, this input field is optional.
Elevation: The vertical portion of the aiming solution, displayed in milliradians (mil) or minute of angle (MOA).
RNG: The distance to the target, displayed in yards or meters. Input field.
W 1/2: The wind speed 1, wind speed 2, and wind direction. For example, if the wind direction (DIR) is 9:00, the
wind is blowing left to right as viewed by the shooter. Input field.
NOTE: The wind speed 2 field is optional. Using both wind speed 1 and wind speed 2 is not an effective way
to account for different wind speeds at different distances between you and the target. Using these fields
is a way to bracket (isolate) the wind values and calculate minimum and maximum windage values for the
solution.
Windage 1: The horizontal portion of the aiming solution based on the wind speed 1 and wind direction,
displayed in milliradians (mil) or minute of angle (MOA).
Windage 2: The horizontal portion of the aiming solution based on the wind speed 2 and wind direction,
displayed in milliradians (mil) or minute of angle (MOA).
Additional Output Fields
Aero. Jump. Effect: The amount of the elevation solution attributed to aerodynamic jump. Aerodynamic jump is
the vertical deflection of the bullet due to a crosswind. Aerodynamic jump is calculated based on the wind
speed 1 value. If there is no crosswind component or wind value, this value is zero.
Bullet Drop: The total drop the bullet experiences along its flight path, displayed in inches.
Cos. Incl. Ang.: The cosine of the inclination angle to the target.
H. Cor. Effect: The horizontal Coriolis effect. The horizontal Coriolis effect is the amount of the windage
solution attributed to the Coriolis effect. This is always calculated by the device, although the impact may be
minimal if you are not shooting at extended range.
Lead: The horizontal correction needed to hit a target moving left or right at a given speed.
TIP: When you enter the speed of your target, the device factors the necessary windage required into the total
windage value.
Max. Ord.: The maximum ordinance. The maximum ordinance is the maximum height above the axis of the
barrel that a bullet will reach along its flight path.
Max. Ord. Range: The range at which the bullet will reach its maximum ordinance.
Remaining Energy: The remaining energy of the bullet at target impact, displayed in foot-pounds of force (ft. lbf)
or joules (J).
Spin Drift: The amount of the windage solution attributed to the spin drift (gyroscopic drift). For example, in the
northern hemisphere, a bullet shot out of a right-hand twist barrel will always deflect slightly to the right as it
travels.
Time of Flight: The time of flight, which indicates the time required for a bullet to reach its target at a given
range.
V. Cor. Effect: The vertical Coriolis effect. The vertical Coriolis effect is the amount of the elevation solution
attributed to the Coriolis effect. This is always calculated by the device, although the impact may be minimal
if you are not shooting at extended range.
Velocity: The estimated velocity of the bullet when it impacts the target.
Velocity Mach: The estimated velocity of the bullet when it impacts the target, displayed as a factor of mach
speed.
