MIL-system scopes have become very popular among tactical shooters. MIL scopes have the advantage of allowing you to use the mil-dot divisions within the reticle to calculate the target’s distance. A mil-based ranging device can be used to calculate distance to targets if you know their size. This NRA video will show you how it is done.
Milliradian Definition & Yardage Ranging Formula “Milradian” or “Milrad”, is shorthand for Milliradian. It is an angular measurement unit. Subtension 1 mil is equal to 3.6 inches at 100 meters or 36 inches at 1000 yards. In metric units, 1 millimeter is 10 cm at 100 meters or 1m at 1,000 meters. This subtension, along with the size of the target or a reference object close to it, allows for a very accurate estimation of the distance to the target. Based on MIL measurement, the formula to calculate range (in yards), is:
Height of Target in Inches (divided into 36) x 1000, divided with the number of mils.
If a 14-year-old target is placed on a 14-inch high pole, the distance is 129.67 yards. If a tall target measures 3m from top to bottom, it will be 129.67 yards. The distance can be calculated as follows: 14/36×1000 = 389, then divided 3 = 129.67. To find distance in meters, you can also use another conversion.
Can you estimate range with an MOA-Marked reticle? Yes You Can…
Reader Josh offers this helpful advice: “It is worth noting that the ability measure range does not only exist in mil-based systems. MIL is just another unit that measures angles. Any angular measurement will do. Similar formulae can be used to range with MOA marks, considering that most people know that 1 MOA equals approximately one inch per hundred yards. Mils have the advantage of being precise. The MOA-inch measurement can be wildly off by 0.047. MILs are, therefore, a better unit.
