Grid Mil-Dot. Theory and method of determining distances

It was clear that she was aware of the size of the object. twisting drums

Grid mil-dot

Title Mil-dot derived from Milliradian Dot (milliradiannaya point). Hence, Mil, Mila, abbreviated from “milliradian.”

1 milliradian = 1 thousandth distance = 3.4377 MOA

Determining the distance using the Mil-Dot grid

Using

  • Estimate the size of the object.
  • Measure the object in miles using a grid. Mil-dot.
  • According to the formula, calculate the distance in meters to the object.

Formulas

  • Width or height of the object (in meters) x 1004 / Width or height of the object (in miles) = Distance (in meters)
  • Width or height of the object (in centimeters) x 10 / Width or height of the object (in miles) = Distance (meters)

Example:

40 cm x 10/2 mil = 200 meters

Determining the distance using the Mil-Dot grid according to the human figure

It can be determined by the distance. The figure is a height of 180 cm.

Vertical Correction Using the Mil Dot Grid

Recalculate the grid values Mil-dot at MOA, that is, we translate milliradians in angular minutes. We use the formula 1 milliradian = 3.4377 MOA. It turns out this picture:

Example №1

We have an ammunition caliber .223Rem Tula plant. And we have a table of verticals.

Vertical amendments to MOA:
Distance, meters 0 50 100 150 200 250 300 350 400 450 500
Weapon adjusted to 100 m —- 0.3 0 0.7 1.8 3.1 4.6 6.2 8.1 10.2 12.6
Weapon adjusted to 200 m —- -1.5 -1.8 -1.1 0 1,3 2.8 4.4 6.3 8.4 10.8
Weapon adjusted to 300 m —- -4.3 -4.6 -3.8 -2.8 -1.5 0 1.7 3.5 5.6 8.0

We recount it all in relation to the grid Mil-dot and we get, for example, for a weapon, shot at 100 meters, this picture:

And for a weapon, shot at 200 meters, this picture:

Example 2

See the grouse:

Determination of distance

The height of his body is usually 25 cm. We measure black grouse. Its angular size is 1 mil. Calculate the distance: (25 cm x 10) / 1 mil = 250 meters. We have a .223Rem caliber ammunition from the Tula plant.

Relative reduction of the trajectory, see:

Relative reduction of the trajectory, see:
Distance, meters 0 50 100 150 200 250 300 350 400 450 500
Weapon adjusted to 100 m -4.0 -0.2 0 -3.8 -12.7 -27.8 -50.5 -82.7 -127.0 -186.4 -264.3

For a distance of 250 reduction in trajectory -27.8 cm

Amendment in Mil: (27.8 cm x 10) / 250 meters = 1.112 Mila

Calculating the aiming point

That is, with a small error, you can aim at 1.125 Mila like this:


The same general view:

For the distance using the MilDot grid

Using

  1. Estimate the size of the object. Find the corresponding column in the table.
  2. Measure the object in miles using a grid. Mil-dot. Find the corresponding row in the table.
  3. This is a list of objects that are shown.
