Nonsense.
<begin standard screed>
There is nothing "metric" about mils.
Both milliradians and MOA are measurements of angle which have <span style="font-weight: bold">nothing</span> whatsoever to do with any system of linear measure.
There are two times Pi radians in a circle, and a milliradian is simply one-thousands of a radian.
One milliradian is an angle which subtends an arc whose length is 1/1000th of the distance from the vertex.
In other words, one milliradian subtends an arc whose length is:
1 yard at 1000 yards.
1 meter at 1000 meters.
1 mile at 1000 miles.
1 league at 1000 leagues.
1 fathom at 1000 fathoms.
1 inch at 1000 inches.
1 foot at 1000 feet.
1 lightyear at 1000 lightyears.
1 attoparsec at 1000 attoparsecs.
3.6 inches at 3600 inches (100 yards).
It has nothing to do with any English or Metric system of linear measure.

Ummm, bad math. One thousand divided by 25 is 40, not 25. However, that comparison ignores factors like dust and other particles in the air as well as mirage, so the comparison is not apt.

Agreed. In fact, a high magnification will, well, <span style="font-style: italic">magnify</span> whatever level of <span style="font-style: italic">un</span>steadiness that one exhibits.
