Re: Duplex Reticle - At a disadvantage?
A duplex can still be used similar to other "tactical" reticles.....within reason.
Set up a target with inch grid lines at exactly 100 yds.
Look through the scope and determine how much distance (in inches) there is between the X in the middle and the thicker portion of the vertical wire below the X.
If that distance is 3", then you have an automatic 3 moa (approx. but very close to true moa) hold over or windage marker.
If that distance is 5", then you have a 5 moa marker, ect.
This distance or subtention can easily be visually divided by 2 or maybe even 4 for finer moa values.
