This is quite repeatable and is not due to backlash as none was detected.

So it looks like I will have to come up with a drop chart for this particular scope as my balistic program only has IPHY and MOA not MOA+8%......LoL.

What scope are you useing
range it,check the wind, dial in correction, aim and only one shot

    It is a Clearidge 2.5-12.5x42 Ultra XP5 on 20MOA rail.

    It is a nice scope to look through, so it is a pity that they could not get the elevation turret a bit more accurate.
    I read somewhere that the industry standard for turret accuracy of movement, is 2.5% so it is a bit disapointing that this scope is just a bit less than 10%.
