Many guys getting started in long range shooting are confused about what kind of scope they should buy — specifically whether it should have MIL-based clicks or MOA-based clicks. Before you can make that decision, you need to understand the terminology. This article, with a video by Bryan Litz, explains MILS and MOA so you can choose the right type of scope for your intended application.
You probably know that MOA stands for “Minute of Angle” (or more precisely “minute of arc”), but could you define the terms “Milrad” or “MIL”? In a helpful video, Bryan Litz of Applied Ballitics explains MOA and MILs (short for “milliradians”). Bryan defines those terms and explains how they are used. One MOA is an angular measurement (1/60th of one degree) that subtends 1.047″ at 100 yards. One MIL (i.e. one milliradian) subtends 1/10th meter at 100 meters; that means that 0.1 Mil is one centimeter (1 cm) at 100 meters. Is one angular measurement system better than another? Not necessarily… Bryan explains that Mildot scopes may be handy for ranging, but scopes with MOA-based clicks work just fine for precision work at known distances. Also because one MOA is almost exactly one inch at 100 yards, the MOA system is convenient for expressing a rifle’s accuracy. By common parlance, a “half-MOA” rifle can shoot groups that are 1/2-inch (or smaller) at 100 yards.
What is a “Minute” of Angle?
When talking about angular degrees, a “minute” is simply 1/60th. So a “Minute of Angle” is simply 1/60th of one degree of a central angle, measured either up and down (for elevation) or side to side (for windage). At 100 yards, 1 MOA equals 1.047″ on the target. This is often rounded to one inch for simplicity. Say, for example, you click up 1 MOA (four clicks on a 1/4-MOA scope). That is roughly 1 inch at 100 yards, or roughly 4 inches at 400 yards, since the target area measured by an MOA subtension increases with the distance.
MIL vs. MOA for Target Ranging
MIL or MOA — which angular measuring system is better for target ranging (and hold-offs)? In a recent article on his PrecisionRifleBlog.com website, Cal Zant tackles that question. Analyzing the pros and cons of each, Zant concludes that both systems work well, provided you have compatible click values on your scope. Zant does note that a 1/4 MOA division is “slightly more precise” than 1/10th mil, but that’s really not a big deal: “Technically, 1/4 MOA clicks provide a little finer adjustments than 1/10 MIL. This difference is very slight… it only equates to 0.1″ difference in adjustments at 100 yards or 1″ at 1,000 yards[.]” Zant adds that, in practical terms, both 1/4-MOA clicks and 1/10th-MIL clicks work well in the field: “Most shooters agree that 1/4 MOA or 1/10 MIL are both right around that sweet spot.”
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…
1 Milliradian (Milrad or ‘Mil’) = 1/1000th of a radian | 1 Milliradian = 0.0573 degrees.
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 Explained article from targettamers.com 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: 360 degrees = 2 x Pi (symbol π) Radians. That means 1 Radian is about 57.3 degrees. 1 Milliradian (Milrad or ‘Mil’) = 1/1000th of a radian. Thus 1 Milliradian = .0573 degrees.

MIL-system scopes are popular with tactical shooters. One advantage of MIL scopes is that the mil-dot divisions in the reticle can be used to estimate range to a target. If you know the actual size of a target, you can calculate the distance to the target relatively easily with a mil-based ranging reticle. Watch this helpful NRA video to see how this is done:
Milliradian Definition and Yardage Ranging Formula
“MIL” or “Milrad” is short-hand for Milliradian, a unit of angular measurement. The subtension of 1 mil equals 3.6 inches at 100 yards or 36 inches at 1,000 yards. (In metric units, 1 mil equals 10 centimeters at 100 meters or 1 meter at 1,000 meters.) Knowing this subtension and knowing the size of the target (or a reference object near the target) allows the distance to the target to be estimated with considerable accuracy. The formula used to calculate range (in yards) based on MIL measurement is:
Height of Target in inches (divided by 36) x 1000, divided by the number of mils.
For example, if a 14″ tall target spans 3 mils from top to bottom, the distance is 129.67 yards calculated as follows: 14/36 x 1000 = 389, then divided by 3 = 129.67. You can also use a different conversion to find distance in meters.
Can You Estimate Range with an MOA-Marked Reticle? Yes You Can…
Reader Josh offers this handy advice: “It worth noting that the ability to measure range is not unique to mil-based systems. A MIL is just another unit for measuring angles, and any angular measurement will work. Considering that just about everybody knows that 1 MOA is about an inch per hundred yards, similar formulae can be developed for ranging with MOA marks. The advantage with mils is the precise relationship between units — the MOA-inch measurement is imprecise (being off by 0.047″) — so in principle MILs are a better unit”.

Many of our readers are now using smart-phones for ballistic calculations. Now there is a new App for the iPhone which makes mildot target ranging simple and easy. Mil-Dot Rangefinder 2.0 does all the math for you. Just input the size of the target, and the program calculates range instantly, in yards and meters. The standard edition costs just $1.99 while the “Pro” version is $9.99. We think that, if you’re going to really use this program in the field, it’s well worth paying ten bucks for the Pro version. The Pro edition gives you a full-featured ballistics calculator with windage/elevation corrections. That calculator alone is worth the extra money, and the Pro version offers many other features, which are listed below:
Target ranging (yards and meters)
US Army and USMC mil-dot reticles
Target Info display
Advanced ballistics calculator
Fast windspeed/direction adjustment
Range card (ballistics chart)
Point of impact indicator
Bullet drop compensator
Windage/elevation corrections
Time to target
Shot energy/velocity at target
Multiple Ballistic Profiles
This is a very powerful program. We suspect it will take most users a few days before they really understand all its functions and options. To see a more detailed demonstration of the Mil-Dot Rangefinder App, click on the YouTube video below. There’s no voice-over, so the video can be hard to follow. But at least the video showcases the flexibility of the program and the wide variety of functions it offers. Credit The Firearm Blog for spotlighting this useful App.

ShooterReady.com offers an excellent computer simulation that lets you “shoot” three different calibers at virtual ranges out to 2000 yards–complete with sound effects and realistic scenery. You view the target through a 10-20x zoom scope and adjust windage and elevation as with a real scope. A FREE Online Demo is available that lets you practice with a 175gr .308, and also Windrunner .338 and .50 BMG. Atmospheric conditions and range distance change with each stage, so there is plenty of challenge. Warning–if you’re at work, this can be addictive once you get the hang of it.
You can practice Mil Dot ranging on 3 targets: A 12″ X 12″ swinging plate, a 30″ X 18″ knock-down plate, and a regulation 72″ X 19″ knock down plate. Each caliber has 70 range exercises, plus an advanced stage with 25 timed hold-offs, and moving targets.
The CD also includes “Interactive Classrooms” that teach you how to use Mil-Dot scopes and how to use a range card. The presentation on reading Mils and calculating target distances is very well done. It is much easier to learn interactively than by just reading a static manual. Below is a screenshot from the Mil-Dot Ranging “Classroom”.
Trust us, you can learn a great deal from the Free Demo. This is not just a shooter video game. The demo offers a variety of scenarios–enough to keep you occupied for quite some time.
