  The windage and elevation scales of the PROSTAFF 5 Riflescope 2.5-10×40, 2.5-10×50, 3.5-14×40 SF, 3.5-14×50 SF and 3.5-14×50 SF IL are calibrated in divisions of 1/4 minute of angle with a click at intervals 

of 1/4 minute of angle (1 division).

  The windage and elevation scales of the PROSTAFF 5 Riflescope 4.5-18×40 SF and 4.5-18×40 SF IL are calibrated in divisions of 1/8 minute of angle with a click at intervals of 1/8 minute of angle (1 division).

  When adjusting the reticle to the point of aim, remember that 1 minute of angle equals approximately 2.54 cm (1 in) at 91.44 m (100 yd).

Therefore, if the impact point is 5.08 cm (2 in) low and 2.54 cm (1 in) right at 91.44 m (100 yd) Parallax Setting, you should adjust 2 minutes of angle up and 1 minute of angle left.

In the case of 45.72 m (50 yd) Parallax Setting, the adjusting value is 2×. In the case of 68.58 m (75 yd) Parallax Setting, the adjusting value is 1.5×.
