DETERMINING THE BALLISTIC CURVE
For the precise determination of the impact point
correction, the Leica Rangemaster includes the bullet
trajectory on the basis of the used caliber, as well as
the bullet type and weight in the calculation. This
includes the adjustment of the calculation of the
equivalent horizontal distance (
EHr
, see p. 51) of the
holdover (
HOLd
, see p. 22 ) or the sight adjustment
(

, see p. 52) on request. Twelve
different ballistic curves are available for adaptation to
the equipment you are using. From the appropriate
table in the appendix, find the ballistic curve that is
closest to the bullet drop specified by the ammunition
manufacturer. Make sure you choose the appropriate
down range distance.
Example:
The rifle scope is zeroed to 100 meters, which means
that Table 1 is applicable. The specified impact point
for the ammunition used is -15.0 cm at 200 m. In the
corresponding column, this is closest to the value 14.5
cm in row EU7 - this is therefore the appropriate
ballistic curve.
Note:
When using the Leica Rangemaster’s ballistic function
at distances longer than 330 m/yds and/or other
ammunition types that are not covered by the internal
settings of the device, we recommend to either deter-
mine the ballistic data of your ammunition through
practical testing to choose the appropriate curve, or to
determine it with the Leica ballistics calculator and to
transfer it by memory card to the device.
