Note:
The windage and elevation scales of the riflescope 2.5-10x44 SF and 4-16x50 SF are calibrated in division of 1/4 minute of angle with a click at intervals of 1/4 minute of angle
(one division).
When adjusting the reticle to the point of aim, remember that one minute of angle equals approximately one inch (2.54 cm) at 100 yards (91.44 m). Therefore, if the impact point is
two inches (5.08 cm) low and one inch (2.54 cm) right at 100 yds (91.44 m) Parallax Setting, you should adjust two minutes of angle up one minute of angle left. In case of 50 yds
(45.72 m). Parallax Setting the adjusting value is double. In case of 75 yds (65.58 m) Parallax Setting is 1.5 times.
(5) Adjustable objective
