EAC function – brief explanation
Assuming a distance of 400 m
Assumed angle of 40°
Result using Rifleman's Rule: 306 m
Result of EAC function: 321 m
EAC function
As can be seen in the example, the distance determined using the EAC function differs from the Rifleman's Rule by 15 m, which, depending on the calibre, bullet, barrel length, etc., can have a significant influence on the accuracy.
