Page 15 - = = 532 Yards; CALCULATING HOLDS FOR WIND AND MOVING TARGETS; lists one-mil widths; even quarter-mils but with practice you can measure tenths of a mil.

15 height or width carefully in mils, compute it according to the formula and you will find its range. Support your rifle and be precise when measuring objects; any measuring error causes an error in the computed range. Equally, a mistake in estimating the object size results in a proportional range...
