Macv,

The mildot formula is very simple and pretty straightforward.

First things first. Purchase a Mil-Dot master (see link), this way you don’t have to tote a calculator with you. This is the single best investment you can make and it’s around $29.00.

Second, you’ve got to practice, practice and practice even more. An hour or so isn’t enough. The more you practice the better you’ll get. Most folks can break the mil-dots down into 1/2 and 1/4 increments. This is OK, but you want to be able to break them down into 1/8th and 1/10th increments. The smaller the increment the more accurate the range will be.

OK, here goes. If you are going to use yards the formula is target size in inches multiplied by 27.77 divided by the number of mil-dots covering the target.

Here are two examples.

Example # 1 Lets say I’m ranging a deer and a deer’s chest is 18” from top to bottom. 18 X 27.77 = 499.86 so we can round to 500. Let say it takes 1.75 mil-dots to cover the deer’s chest top to bottom. Divide 500 by 1.75 and its 285 yards to the deer.

Example #2 Lets say a ground hog standing is 15” tall. 15 X 27.77 = 417 rounded up. Let say it takes 1.25 mil-dots to cover the ground hog. 417 divided by 1.25 = 333 yards to the ground hog.

If you are going to use meters then the here’s the formula.

If you are going to use meters the formula is target size in inches multiplied by 25 divided by the number of mil-dots covering the target.

Here are two examples.

Example # 1 Lets say I’m ranging that same deer and a deer’s chest is 18” from top to bottom. 18 X 25 = 450. Let say it takes 1.75 mil-dots to cover the deer’s chest top to bottom. Divide 450 by 1.75 and its 257 meters to the deer.

Example #2 Lets say I’m ranging the same ground hog, which is standing 15” tall. 15 X 25 = 375 rounded up. Let say it takes 1.25 mil-dots to cover the ground hog. 375 divided by 1.25 = 300 meters to the ground hog.

It’s pretty straight forward, but buying a Mil-Dot Master sure makes it 10000000 times easier and quicker.

Hope it helps.
