Range estimation

The Nightforce MIL-R™ reticle can provide you with an accurate distance to your target, when the size of the target is known, by utilizing one of the following Mil relation formulas:

• Target Size in Inches ÷ Image Size Measured in Mils in Reticle x 27.77 = Distance in Yards
• Target Size in Inches ÷ Image Size Measured in Mils in Reticle x 25.4 = Distance in Meters
• Target Size in Centimeters ÷ Image Size Measured in Mils in Reticle x 10.93 = Distance in Yards
• Target Size in Centimeters ÷ Image Size Measured in Mils in Reticle x 10 = Distance in Meters

For example, a standard stop sign measures 30” tall x 30” wide. Knowing the size of the target, in this case, a stop sign, and applying the correct formula above, you will be able to accurately calculate the distance to your target.

1. Known target size = 30”
2. Image size = 2.5 Mils. To measure image size of target in Mils, refer to the reticle diagram above.
3. Divide target size (30”) by image size in reticle (2.5) = 12
4. For distance in yards, multiply 12 x 27.77 (constant) = 333.24 yards to target.
5. For distance in meters, multiply 12 x 25.4 (constant) = 304.8 meters to target.

Your ability to accurately measure your target in your reticle does take some practice to become proficient.
