at what magnification does one "mil" equal 3.6 inches at 100 yards. I just got my first mil dot scope, Sightron SII Big Sky 6.5-20x50, and noticed that the distance between the mils does not seem to be the same at different magnifications, at the same range. I stuck a knife in the ground at about 100 yards and looked at it at different magnifications. Not sure what was confirmed. The distance between the mils seemed to be different but then at the same time it didn't.

the center-to-center distance is 3.6" at your max power.

The reason the mils of your scope subtend a different amount at different magnifications is because the reticle is in the second focal plane. With such a scope, the mildots are the correct size at only a particular magnification, which is established by the manufacturer. A mildot reticle located in the first focal plane will be correct at any magnification, but these scopes usually cost much more.

usually the 2nd focal plane mildots are correct on the highest magnification setting.

And if not that, 10x is also a common setting.

And heeeeeerrrrreeees your answer.....

Thanx to cuervo- :)

3.6" c/c of the dots @ 100y at 20X ( at your maximum power setting, which is 20 power, the dots subtend 3.6" center to center of the dots)-:D

Look for a marker on the power ring markings.
Usually a zoom magnification mildot optic will have a denotation on the power level indicator.

Most of the time, it's around 14x you will see a 'Dot', or the number will be painted in with a different color.

My Leupold was modified by Premier Reticle years ago, and it is as TeamRush said.....marked at the 12x by a dot on the power ring (a 6.5-20x Target scope).
