TARGET MENU
TR – Target Range is the distance from the muzzle of the
ri e to the target.
DoF – Direction of re is the direction from the position
of the shooter to the target.
Ideg – Inclination is the angle above or below horizontal
from the position of the shooter to the target.
Icos – Inclination Cosine is the cosine of the angle above
or below horizontal from the position of the shooter to
the target.
TS – Target Speed is the speed of the target
perpendicular to the direction of re.
TD – Target Direction is the direction of travel of the
target perpendicular to the direction of re.
WD – Wind Direction is the direction the wind is coming
from in relation to the direction of re.
WS1 – Wind Speed 1 is a ve second rolling average
wind speed.
WS2 – Wind Speed 2 is a ve second rolling maximum
wind speed.

GUN MENU
MV – Muzzle Velocity is the speed of the bullet as it leaves the
muzzle. MV can be measured with a chronograph.
BF – A Hornady 4DOF Bullet File is a collection of data
required to predict how a bullet will y. Each le includes a
Doplar Radar generated coe cient of drag vs velocity curve,
data about the bullet's weight and inertia and the bullet's
geometry.
DM – A Drag Model is the known aerodynamic drag pro le
of a standard projectile against which an actual bullet is
referenced. Ballistics coe cients based on G1 drag models
are more widely available but ballistic coe cients based on
G7 drag models are more representative of a typical hollow
tip, boat tail bullet. The Hornady Kestrel ships with BF as the
default option but DM can be accessed by highlighting BF in
the Kestrel's Gun menu and toggling left.
BC – A Ballistic Coe cient is a ratio that represents the ability
of the bullet to overcome air resistance and maintain velocity
while in ight in comparison to a standard projectile. Be sure
to match the G1/G7 drag model setting to the BC value you
are using. G1 BCs can not be used with G7 drag models and
vice-versa. BC values can only be used in the Hornady Kestrel
when Drag Model (DM) is selected instead of Bullet File (BF).
BW – Bullet Weight is the weight of the bullet measured in
grains or grams.
