So you have your scope zeroed and there is no zero stop in it off the bat. Paying attention to your revolutions and the amount past the last full turn you would dial the scope all the way down to the bottom and take note of how many mils that was.
Example, if you did 3 revolutions and the scope went 2 more mils (that would land on 3mils since its 5mil per turn and you're counting down) that would mean your scope's zero is 17mil from the bottom of the turret travel and you'd want to start out with 17mils of shims.
*The -10mil base + 10mil shim + 17mil shim would get you 17mils.
*The -9.5base + 10mil shim + 16mil shim it would get a 16.5mil shim stack (to move the zero stop back .5mil).
Does that make sense?
Folks tell me the 3-15 are the same (but they list 35mils of travel vs 40mils in the fixed power) so I am waiting for feedback to really say for sure.
BUT that is the mils version, you mentioned MOA, I have not done any MOA, just mils. If there is solid demand for moa let me know. This all depends if you're even concerned with the labels on the shims. Folks above said the just swapped out shims till it got the height they wanted, the set will certainly provide a variety of thicknesses. I was just trying to have the mils labels close to reality.
