EAC Function
Assume the distance from the target is 400 m
Assume an angle of 40°
Rifleman's rule result: 306 m
EAC function result: 321 m
As the example shows, the distance determined by the EAC function differs from that of the rifleman's rule by 15 m, a distance which, depending on calibre, projectile, barrel length, etc. can already have a significant impact on the accuracy of a shot.
