BD – Bullet Diameter is the diameter of the bullet measured
in inches or millimeters. (Note! Ensure bullet diameter is
correct. The given name of a bullet's caliber does not always
match its actual diameter, for example 300WM is actually
.308", not .300")
ZR – Zero Range is the distance from the muzzle to the target
at which the ri e was zeroed.
ZA - Zero Angle is the angle between the axis of your ri e's
barrel and the axis of your ri e scope. Zero Angle can be
measured using the Calculate Zero Angle tool in the Ri e Zero
Sub Menu.
BH – Bore Hight (Scope Height) is the distance from the center
axis of the ri e barrel to the center axis of the scope. This can
be measured from the top of the bolt to the middle of the
windage turret plus half the diameter of the bolt.
RT – Ri e Twist is the distance it takes for the ri ing of your
barrel to make one full rotation. RT is often provided by
the gun or barrel manufacturer. It can also be measured
by marking a tight tting cleaning rod and measuring the
insertion distance required to make one full rotation.
RTd – Ri e Twist Direction is the rotational direction of the
ri e twist. A right hand twist (most common) is clockwise from
behind the ri e.
Eunit – Elevation Unit is the unit of measure used in a scope
and reticle for elevation and can be changed to Mil, TMOA,
SMOA, inches or centimeters.
Eclck – Elevation Clicks is a user settable ratio of the
number of clicks of the elevation turret required to adjust
the point of aim one Mil, TMOA or SMOA. The Eclck value
can be set in the Eunit sub menu when clik is selected as
the Eunit.
Wunit – Windage Unit is the unit of measure used in a
scope and reticle for windage, either TMOA, SMOA, or Mil.
Wclck – Windage Clicks is a user settable ratio of number
of clicks of the windage turret per TMOA, SMOA, or Mil.
The Wclick value can be set in the Wunit sub menu when
clik is selected as the Wunit.
TMOA – True Minute of Angle is a measure of one actual
minute of angle. 1 TMOA = 1.047" at 100 yards. Most MOA
scopes are TMOA.
SMOA – Shooters Minute Of Angle is a simpli ed
approximation of one minute of angle where 1 SMOA = 1"
at 100 yards.
Mil – Milliradian is a measure of angle using the USMC
de nition of 6283 mils = 1 circle, or 1 mil = 3.438 MOA.
CLIK – Click is the value of each click of the turret where
the user selects the number of clicks equal one TMOA,
SMOA, or Mil, based on the turrets of their scope.
