Understanding Milliradians (Mils) and Mil-Dot Scopes
We first ran this article in 2012, and it was very well received. Since then, many Forum members have requested an explanation of MILS and mildots, so we decided to run this feature again…
In this NSSF Video, Ryan Cleckner, a former Sniper Instructor for the 1st Ranger Battalion, defines the term “MilliRadian” (Milrad) and explains how you can use a mildot-type scope to range the distance to your target. It’s pretty simple, once you understand the angular subtension for the reticle stadia dots/lines. Cleckner also explains how you can use the milrad-based reticle markings in your scope for elevation hold-overs and windage hold-offs.
Even if you normally shoot at known distances, the hold-off capability of milrad-reticle scopes can help you shoot more accurately in rapidly-changing wind conditions. And, when you must engage multiple targets quickly, you can use the reticle’s mil markings to move quickly from one target distance to another without having to spin your elevation turrets up and down.
WEB RESOURCES: If you want to learn more about using Milliradians and Mildot scopes, we suggest the excellent Mil-dot.com User Guide. This covers the basics you need to know, with clear illustrations. Also informative is The Truth about Mil Dots by Michael Haugen. Mr. Haugen begins with basic definitions: 1 radian = 2 PI; 1 Milliradian (Milrad or ‘Mil’) = 1/1000th of a radian; 1 Milliradian = .0573 degrees.
