Gun library
There is room in the Kestrel for up to 16 guns. While it
is possible to copy a preconfigured gun to your Kestrel
and modify the parameter, you should use New Gun
and input all the parameters to ensure MV and DSF Cal
are accurately inputted. You can build a gun library on
a computer using the AB Gun Loader software, and
download the new gun library to the Kestrel (either via
Bluetooth® connection or the Kestrel wired interface).
Downloading a new gun library will automatically
overwrite the previous guns in the Kestrel.
*Note: You should upload any user-created guns to the AB
Gun Loader software that you want to save before down-
loading new guns. The new guns will overwrite current
stored Kestrel guns.
Gun Information screen
Once you have selected your gun, you’re now ready to
enter or modify all relevant parameters pertaining to the
set-up of your rifle. These parameters include muzzle
velocity, drag curve, ballistic coefficient, bullet weight,
bullet diameter, bullet length, zero range, zero height,
zero offset, bore height, rifle twist, rifle twist direction
and sight adjustment (click).
• On the Gun Information screen, use buttons to
highlight the gun parameters.
• Use and to adjust the value.
• Press to enter the highlighted parameter’s
screen. Here you are also able to adjust the
parameter’s value as well as the unit of measure.
(For example, meters per second to feet per second.)
• Press to exit to Main AB screen once all values are
correct.
See below for more information on Muzzle Velocity, Drag
Curves and Calibration.

notes on Muzzle Velocity
• When a bullet is in the transonic range, a small dot
will appear to the left of the muzzle velocity value
(figure 1).
• When a bullet is in the subsonic range, a larger dot
will appear to the left of the muzzle velocity value
(figure 2).
• In cases where the bullet is supersonic, there are no dots
next to the muzzle velocity value.
