It says on the Kalinka website that the elevation knob adjusts in equal amounts of MOA - instead of matching the trajectory of the 7.62x54R round. The picture of the knob looks like it clicks in equal increments. The one on my PSL is calibrated for 7.62x54R and the clicks are uneven and match the trajectory of the 7.62x54R round rather than MOA.

Am I reading this right, that the Kalinka scopes don't have any true calibrated bullet drop compensation?

If not, and I wanted a higher magnification scope for my PSL, what suggestions do you have?
