EAC function
Assumption of a distance of 400 m
Assumption angle of 40°
Result Rifleman´s Rule: 306 m
Result EAC function: 321 m
As can be seen from the example, the determined distance with the EAC function differs from the Rifleman´s Rule by 15 m, which can already have a significant impact on accuracy depending on caliber, bullet, barrel length, etc.
