Specifically, that would be a 1 inch radius circle at 100 yards.
See, since 100 yards equals 3600 inches and we're talking about a 1" radius circle at that range, we have an easy Trig problem: arcsin(1/3600) ~= .015915 degrees, which is sufficiently similar to one minute (1/60 degree) ~= .016667
Make sense now?
