Glossary

RZR is the point, where the bullet trajectory intersects the line of sight for the second time.
Hereby the bullet may not move away from the line of sight more than 4 cm.
In the given example, the aiming point does not have to be altered up to a distance of 209 m.
The sighting-in is still possible at 100 m.
With a 7 x 64 for example, the weapon would have a 4 cm high point of impact at this distance in order to use the 209 m of the 7 x 64 example without correction of the aiming point.
The RWS zeroing target with the corresponding directions for a hit accurate sighting-in is ideal for test firing. (Available at rws-munition.de)
RWS is known for, that the point of impact hardly changes from lot to lot.
Nevertheless, when opening a cartridge package with a different lot number, the obligatory trial shot should be a commitment.
