They told me that when I change power on the scope the reticle lines, or dots also change from closer to further apart depending on what power you choose. This may be wrong but that's what they told me.
I am certainly no expert... but I really do not think so... Most American scope manufactures put the reticule ahead of the power ring, while European scopes are the opposit and the reticule changes with power. You can actually see it change as you move the Power Ring - I do not see that in the Leupold.
Also look on your Power Ring - you will see 2 small Gold Dots and in another place where there are 3 Gold Dots. All of this computes into the settings of the rings.
As i understand it???? the range lines represent a certain distance between lines when on 9 power. Same way with a mil-dot or even the Nikon Omega... but to be honest with you I have never read the directions because it did not mean a thing to me as I use the scope differently than designed.
So say I had a close shot at 20yds, 9 power would be way too much to use as the target would be way too close. So I could'nt sight in the way they said using 9 power, then change it to say 2 power for a close shot as my marks would be off.
When I sighted the scope in - I laser bore sighted it here at home then on 9x shoot a 25 yard target - then a 100 yard target - then the rest of the targets.
In real life about the only time I would ever use 9x is for a 175 plus yard shot when I was on a rest... other than I am somewhere between 3 and 5 power depending on the terrain.
OK - I just looked again - The reticule does not change size - but the distance between dots does change and is only constant on one power setting - so 9x is the suggested power to achieve the range distance indicated.
All to complicated for me - I just use the marks to fit my needs...
