Yeah, if you could please. What I'm seeing in the POSP manual, one windage click moves the POA by 10cm at 100m, 30cm at 300m. But no stated relationship between elevation and windage corrections. I'd say a "click per click" would be too drastic, in view of the following:
Bullet derivation (the offset in-flight due to yaw) compensates the scope offset to a large extent. From Andrew (gunsmith at Kalinka Optics):
Shooting distance, m Average POI offset, cm Derivation, cm Difference, cm
0 +2,5(right) 0 2,5
100 0 0 0
200 -2,5(left) 1 -1,5
300 -5 2 -3
400 -7,5 4 -3,5
500 -10 7 -3
600 -12,5 12 -0,5
700 -15 19 4
800 -17,5 29 11,5
900 -20 43 23
As you can see, the angle between scope and rifle axis is compensated by derivation at 600m (when the scope is zeroed at 100m). This is valid for SVD and POSP.
