DETERMINING THE BALLISTICS CURVE
To adjust the equivalent horizontal range calculation
(EHR, see p. 44), the point of aim (HOLd, see p. 44) or
the reticule adjustment (MOA, see p. 45) to different
calibers, ammunition types and weights, you can
choose from 12 different ballistics curve.
The Appendix contains six tables, three different ones
for zeroing distances in meters and in yards.
In the table that corresponds to the set zeroing
distance, find the ballistics curve that is closest to the
point of impact specification provided by the
ammunition manufacturer.
Example:
The weapon is zeroed to 100 meters with the
associated telescopic sight, Table 1 is applicable. The
ammunition manufacturer specifies 15.0cm at 200m
as the point of impact for the ammunition used. In the
corresponding column, this corresponds most closely
to the value of 14.5cm in the EU7 line - this is
therefore the appropriate ballistics curve.
Note:
When using the ballistics function on the Leica Geovid
HD-B, particularly at ranges of > 300m / 300 yards,
we recommend determining the ballistic data for your
ammunition by practical trials, so that you can select
the appropriate curve.
SETTING THE BALLISTICS CURVE
Start with step 1 if you have not yet opened the menu
system and with step 3 if you have already set the unit
of measure and
is still flashing in the display.
