Mil-Dot reticle scopes are optics that make it easy to calculate target distances without fancy equipment. For the first time, such a reticle was used in submarine periscopes; later, its scale was recalculated for military and amateur rifles with an optical sight to determine the distance to distant objects or in order to take into account and compensate for the decrease in the bullet trajectory. After learning the basics with the Mil-Dot grid, you can calculate distances quickly and easily.

Steps

Method 1 of 2: Theory

1. 1 The Mil-Dot reticle for binoculars and periscopes is different from that of rifle scopes. They measure the same type of angular distance, but rifle scopes are labeled 10 mil instead of 1, which is more suitable for sniper use.
2. 2 Mil is 1-6.175 circles. But to simplify calculations in the US Army, a ratio of 1-6,400 circumference is adopted. Soviet and Russian riflescopes are characterized by a ratio of 1-6,000 circumference. This means that the error in calculating the distance is 3%.
3. 3 When seeing a Mil-Dot reticle in a telescopic sight, you need to understand that one mil is the distance from the center of one point to the center of the next (not the distance between two points). The height of each dot is 0.2 mil and the spacing between the dots is 0.8 mil for the US Army's round Mil-Dot grid.
4. 4Mil-point distances on a second focal plane and variable magnification reticle are generally accurate only at the highest magnification.

Method 2 of 2: Measuring Distance

1. 1 Calculate the distance to the object by multiplying the height (width) of the object by 1000 and dividing by the number of mils the object is occupying.
   • For example, an object 1.8 m high and 8 mils in size is 225 m away. 1.8 x 1000/8 = 225
2. 2 Calculate the distance as accurately as possible, as any "additional mistake" (made by you) can make the result unacceptable.
   • Divide the mil points into as small segments as possible and size the object as accurately as possible.
   • The 1.5m wide object occupies 2.8mils and is 536m away.
   • If you estimate that the object is 2 m high instead of the actual 1.67 m, then the error in determining the distance will be 100 m, which can mean a few centimeters miss when firing .308 cartridges.
   • For correct results, size the object in tenths of a meter (3.4 or 3.5 meters high?). Also note the mil interval with tenths in mind. Both require training, but only an ideal estimate can provide a perfect calculation of the distance.
3. 3 Use a calculator if necessary. Some equations can be quite complex and the key to success is accuracy, but the speed of a calculator can also help in some situations.

Tips

• If you are calculating using the dimensions of objects in yards, then the distance to the object will be in yards (in the same way, the units of any system will give the distance in the same units; the size in inches will give the number of inches to the target, kilometers - kilometers, etc.) )
• A more powerful telescope will mean you will lose target as a result of recoil, less powerful will allow you to aim faster in rapid fire.
• Mil-Dot can also be used to compensate for bullet droop or wind correction.
• The ability to hold the telescope at rest will affect the accuracy of the target's silhouette measurements in mils.
• For better distance calculations, high-tech tripod scopes should be used, as rifle-mounted scopes can be massive or damaged if you drop the rifle.

Warnings

• A careless estimate of distance is the result of a careless estimate of the target's size and silhouette in miles.
• Firearms can be very dangerous and even deadly. It should only be used if you are an experienced shooter or under the direct supervision of an experienced instructor.
• When shooting, be sure to adhere to government regulations regarding the use of firearms.
