Range Estimation: Mil Relation/ Milliradian (MRAD).

Check out the Facebook page!   / mikem0331onyoutube   Range estimation using milliradians, or mils can be very useful when your target is partially obscured, moving, or doesn't come in exact sizes. But if you have a close by stationary target of known dimension, you can use mils in a reticle in a riflescope, binoculars or spotting scope to estimate the range. Mils measure angular width. A radian is an angle whose width of arc equals the length of its radius. Since a circle's circumference is 2Pi times the length of its radius, there are 6.283 radians in a full circle. A mil is 1/1,000th of a radian, which adds up to 6,283 mils in a full circle. This subtends to a 1 yard arc at a 1,000 yard radius. Also a 1 meter arc at 1,000 meters. There are several formulas that can be used: (target size in inches X 27.778) divided by target size in mils = Range in yards. (target size in yards X 1,000) divided by target size in mils = Range in yards. (target size in meters X 1,000) divided by target size in mils = Range in meters. (target size in centimeters X 10) divided by target size in mils = Range in meters. Example: A 6 foot (2 yards) tall man is in your scope and is 4 mils tall in your reticle 2x1,000 (2,000) 2,000 divided by 4 mils = 500 yards away
