If in the 1st focal plane one Mil = 3.6" @ 100 regardless of the power setting.
If in the 2nd focal plan one Mil is anything but 3.6" @ 100 for any power setting except one, usually 10X.
And who knows what the actual power is at any of those numbers on the adjustment ring.
All of this is unless I'm backwards......again /ubbthreads/images/graemlins/frown.gif
