Based on the ballistic data of the load used, select the ballistic ring from Table 1 whose values are
closest to the ballistics.
If the ballistic values are known based on zeroing at 100 m, the required ballistic ring (4) can be
determined directly from Table 1. However, most ballistic data in catologues or on the ammunition
package are based on the most favourable zeroing range (GEE).
These values must always be calculated to zeroing at 100 m as follows:
For example, calibre .30-06 RWS with 9.72 g TIG bullet based on a GEE of 184 m:
