People often ask, how to use Millirad Rangefinder?
Let’s find out!
How to Use Millirad Rangefinder?
Hunters use laser rangefinders to determine distances. However, if the user doesn’t know their formulas, then they may need to give up on using this device.
A mildot slide ruler is a type of tool used by shooters to measure distances. It can be used to calculate the range of a rifle or pistol. The Mildot slide rule is an analog device that measures the distance of a target. It does not require batteries and eliminates the need to perform calculations.

Measuring for Distance
A prairie dog is about 25.4 centimeters tall. That means he takes up 1millimeter space on the crosshair. It is 10 inches long. So using the formula, we get 10 inches x 25.4 centimeters 250.8 centimeters.
Then we divide by 1 millimeter or 0.0254 meters, and we get 250.8 centimeters divided by 0.0254 meters equals 9.965 meters. This is the distance from the center of the crosshair to the tip of the prairie dog’s nose.
Prairie dogs are cute little creatures that live underground. They’re also genius. They use their brains to calculate distances. Converting miles into yards, we get 277.78 yards to prairie dog. Converting meters into yards, we get 254 yards to prairie dog!

What is Mildot?
Mil is not an abbreviation of the military. Mil or MRD is a shortened term for milliradian, and yes the military uses mils in their optics, but not as an abbreviation for military, but instead as a measurement of angle.
A milliradian is 1/1000th (0.001) of a radian, and a radian is a portion (1/360th) of a full circle (2Ï€). If you were to measure the arc created by two radius lines starting at the center and ending at the circumference of a full circle, then you would measure it in degrees.
There are approximately 6,283 million milliradians in an entire circle.
Radian and milliradian are two units of angular measurement used in calculus and physics. We use them for shooting too.
In the military, 1 mil is used as the smallest unit of distance. When you use a scope with dots, you must be careful about how far apart the dots are. If the dots are too close together, then the dots won’t represent 1 mil. If the dots are spaced farther apart, then the dots will appear smaller than 1 mil.

Mildot vs Distance
Mils are angular measurements. Angular measurements are used to determine the position of objects relative to each other. Linear measurements are used to determine distances. Distance is measured by multiplying the length of a line by the number of units along that line. For example, if you wanted to know how far away something was, you could multiply the object’s length (in feet) by the number of feet away from you.
A mil equals 0.0254 inches or 25.4 mm. 1 mil at 525 yds 18.9″. 100 yards 3.6 inches. 100 meters 10 centimeters. 200 yards 7.2 inches etc.
The Metric system is more accurate than the imperial system. When measuring distances, it’s easier to use the metric system because you can easily convert to imperial units. You need to know both metric and imperial to work well as a sniper.
For sighting in and tracking rifle scopes, we’ll take you through the math of when knowing the linear distance and using it for getting a mil correction is helpful.
Most shooters and hunters in the US are already accustomed to inches and feet, so we’re going to provide formulas for both systems, so you can use whatever you naturally find to be convenient.
A side note says that the constant 10 is used to convert meters into centimeters. This means that the formula is correct because the output is always going to be several centimeters.
Mildots are the smallest unit used by military snipers. They measure the distance between two points. A sniper uses them to aim accurately.

Understanding Mil Advantages
Mil should not be confused with MOA. MOA is an abbreviation for minutes of angle. Both MOA and MIL are angular measurements. Mil can be used as a holding over correction factor for bullet drop if weapon ballistics are known. Wind drift can be corrected by using MIL.
A mildot reticle is used to measure distances. You can use it to estimate the size of an object at a given distance, or you can estimate how far away an object is based on its size. In this case, you can tell that the prairie dog is about 1 mil away because the dots on the elevation crosshair line up with the dots on the mildot reticle.
Prairie dogs are estimated to be around 300 yards (250 meters) away. You should shoot them at least 300 meters (250 meters). You might want to aim slightly higher or lower than this distance depending on your gun.
