Determining The Ballistic Curve - Leica GEOVID HD-B 3000 Notice D'utilisation

DETERMINING THE BALLISTICS CURVE
There are 12 ballistics curves to choose from to
allow for a calculation adjustment of the equivalent
horizontal distance ( , see p. 52), the holdover
EHR
( , see p. 52), or the reticle correction (
HOLd
p. 54) to the various calibers, as well as bullet
types and weights. There are 6 tables provided in
the Appendix, three each for zeroing distances in
meters and yards. Find the ballistics curve that is
closest to the point of impact specified by the
ammunitions manufacturer in the relevant table
matching the zeroing distance.
Example
The weapon and rifle scope are zeroed to a dis-
tance of 100 meters (Table 1 applies). The point of
impact for the ammunition used is stated by the
manufacturer as 15.0 cm at 200 m. In the relevant
column, this is closest to the value 14.5 cm in row
– and is therefore the correct ballistic curve.

Note
We recommend determining the ballistics data of
your ammunition in practical tests to select the
correct curve when using the Leica Geovid HD-B/
HD-R's ballistic function at distances greater than
, see
MOA
300 m/yds and/or with ammunition types not
covered by the device-internal settings. Alterna-
tively, you can use the Leica ballistics calculator
(http://ballistictool.leica-camera.com) to calculate
new settings and transfer those to the device via
the memory card.
