Long Range 101 Part 84 - How Mil-Dots are Used for Ranging Targets

Ranging targets with your scope reticle discussed in detail.
Ranging Formulas:
Target size (any unit) x 1000 / Mils = Range (any unit)
Target Size (inches) x 25.4 / Mils = Range (m)
Target size (inches) x 100 / MOA = Range (yards)
HOW TO USE:
Collect and record the dimensions of various potential TRPs (target reference points) in your dope book. Try to anticipate any possible objects that you may see in your AO that could be used to range distances to various TRPs on your range card.
Draw up range card... designate and range all your TRPs ahead of time. This will enable you to deliver fire very quickly when a target presents itself in proximity to a TRP at a predetermined distance.
If target presents itself at an unknown range, you may have to range the target itself (assuming you know its dimensions).
Advantages:
Positive range bracket acquisition
Passive range finding system (does not emit light)
Mils are always available -- can't loose your optic
Not battery dependent -- can operate for extended periods w/o battery resupply
Limitations:
Have to know target dimensions
The full known dimensions of the object being ranged must be visible and should be situated perpendicular to the range finding device
Requires extreme steady position
Only relatively effective out to 700 yards for most applications
Typically takes 10 -- 30 seconds to accomplish
When to use Ranging Reticles:
At a minimum, an optical trigonometric confirmation of any target's range should be performed when time allows -- don't trust LASER or GPS readings alone.
Use in situations where use of LASERs may risk enemy detection.
Although reticles will have somewhat limited use at longer ranges do to error probability the ranging reticle will be your PRIMARY RANGING BACKUP & CONFIRMATION METHOD.

What do you mean when you say "triangle" ? Its right there at 20:31 "bigger base on your triangle? Also, thanks for these videos they're really helpful!

@COFirearmsInstructor 9 жыл бұрын

***** All this math is based on trigonometry which is based on triangles. Imagine a triangle with a side of 40" and the other sides of 500 yards or 6000 inches. It's a pretty stretched out triangle. Because the "base" or short side represented by the target height is so much less than the others sides representing the distance to the target it makes the angle very sensitive. I hope I explained it well enough.

TiborasaurusRex are there any reticles that operates with meters ? or all reticles use mil and yards??

@iCanHazTwentyLetters 9 жыл бұрын

Berk Yilmaz Glad you asked. this concept is not always described well by american and british shooters, who most often use the imperial system. The short answer: •MOA is perfect for Imperial (yards) units. But you can also use MIL for this purpose, because of its mathematical simplicity. •MIL is perfect for metric units! One MIL at 1000m = 1m. NATO uses meters and MIL.

I prefer an MOA scaled reticle for range finding since it is more precise means to range relatively small targets at long range. MOA Formula (for scopes featuring MOA incremented reticle) •Target height in inches X 95.5 / target height in MOA = distance to target in yards Of course, before going out into the field, operator can produce a chart for what the target distance is based on possible subtensions of reticle to target.

25.4 comes from the formula: 39.37 inches in 1 meter. 1000/39.37 = 25.4. You can also get your range in yards by dividing 1000 by 36 which equals 27.77. In each case the object is measured in inches.

27.77/78 is 1000 inches I kept fooling around with the ole 1000' course range and why and how it was set up Some thing to do with the click adjustments on the rifle to get a base zero to work off of ,the initial zero or some such. And later saw the same 27.77/78 appear in these formular for range estimation.. Any way.. I am certain there are down and dirty methods of shooting under stress from a base zero that isn't talked about much.. Such as the danger zone mentioned here.. Really blow some minds when they hit to igoddamn auto spell-/"&$)?!'e uphill / downhill calculations etc. I got to say I been told this is all going away militarily ,the whole USMC SS schools are being done away with the whole mos is going away..

I find the MOA formula easier and quicker to use in the field (at least out to about 600 yards anyway); e.g. A 30" human torso (waist to top of head) measured at 5 MOA (or 1.5Mil - close anyway) is around 600 yards. So 30"/5moa=6 for human torso but 9"/3moa (or .9 mil)=3=300 yards for a coyote (top of fur on back to bottom of fur on belly); 12"/4moa (1.2mil)=3=300 yards for an avg standing Prairie Dog. I can do same with mil reticle but must convert mils to moa so it adds an additional math step - just divide Mil reading by 3 for MOA. And, prior to obtaining my first focal plane scope with MOA reticle, I did use a Vortex 8x28 Monocular with a mil reticle to fairly accurately measure coyotes and prairie dogs (knowing there's 3.44 MOA per mil). Like you said, these fabulous cameras and operating systems (eyes and brains) our Creator gave us do pretty good job of incrementing by ten automatically with a little practice. fwiw.

Thanks a lot for this video. Had almost no knowledge about this subject and its practical application, but you're video helped to gain a lot of it. One thing I need to point out though, and I may be wrong here (though, pretty sure that I'm not) - when talking about scaling error probability of, lets say, 0,1 mil we need to consider that the error can be +/-, that is, our error can lead us to determine a range that is either closer or further than the actual distance to the target. In this regard, when evaluating the possible error with regards to danger space we actually need to compare it to half of the danger space, as danger space includes the allowable error on both "sides" of the target (either closer or further out). So, in the example of 500m range the actual allowable error in terms of danger space would be 38,5m, which in this case would results in +/- 0,145 mils. So, in this case, for a novice, assuming error could be up to 0,25 mils the actual maximum range would be below 500 meters. Hope this makes sense and I'm not misunderstanding anything. Thanks once more for the good content on long range shooting! Keep up the good work!

Hi Rex. I'm really enjoying your videos. I do believe there is an error in the MOA ranging formula. I'm pretty sure it should be: (Range in inches/ measured MOAs) X 95.5 = Range in yards. This is roughly 4.5% different than the formula given in the video. You may have intentionally simplified the formula but since the series is focused on extreme range precision shooting.. I thought I'd note it. Thanks and keep the good stuff coming!

Johnny Cash this is from Google cu·bit ˈkyo͞obit/ noun plural noun: cubits an ancient measure of length, approximately equal to the length of a forearm. It was typically about 18 inches or 44 cm, though there was a long cubit of about 21 inches or 52 cm ... sometimes used in the Bible, something that based on his videos Rex is familiar with. I assume that the referance to an ancient biblical measurement in a video about modern precision shooting is a joke. I might be wrong though. Homeschool in the USA btw .

Question , maybe I missed this but my scopes are all MOA both turrets and reticles with SFP so when I zoom in with my scope the size of the target changes but not the reticle. So if say 400 yards distance @ 6.5 power the target is much smaller than @ 20 power and therefore the size in measurement is different. Is there a base or standard power to be at if the scope has a SFP ? FFP changes with the reticle as you zoom in and out.

Need some more information. I fully understand what you're explaining here. But I am confused to the magnification of scope.

Okay, if one does not have a mil-dot scope with first focal plane reticle, what does one use as a base? There, somewhere, has to be a zoom factor correction to be a correction for the difference between 6x zoom and 20x zoom. An object @200 yrds measures x-mil dots with 6x and will measure far more mil-dots with 20x, but the calculation does not account for this in it's equation.
