Re: Zeiss mil dot help (new scope)
I just finished a tactical course and one of the exercises was ranging with a mil dot scope. I discovered the Zeiss Conquest 6.5-20 ranges accurately only at 12 power. I then realized what the big ridge is on the power adjustment knob. It's the 12 power setting for quick ranging without having to look off target.
You can verify this by making two heavy black lines 3.6 inches apart and moving 100 yards away. 10 power is close but 12 power is bang on the center of the mil dots.
