The x10/x20 just means that's the magnification at which the MILs are in the correct proportion to the background image. At higher magnifications the MIL dots will appear closer together relative to the background, at lower magnifications the MIL dots will appear further apart relative to the background. So for the x10 scope correct proportions between reticle and background are displayed at x10 magnification, whereas in the x20 scope correct proportions are shown at x20 magnification."P.Shooter71"I was wondering more about the reticle part because the one scope come with 1/2 mildot 10x and the high mag scope came with 1/2 mildot 20x . It looks like 10x is just in middle of scope where 20x reticle covers the whole lens which I think is better.
The benefit with the x20, is that at x10, the half MIL marks become 1 MIL marks, because at x10 mag the background has been shrunk by half compared to at x20 mag because the reticle hasn't changed in size. This is the point Bobby was trying to make.
