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.

couldn't i use (height x27.8/mil=range in yrds) and still get accurate range?

@iCanHazTwentyLetters 9 лет назад

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 лет назад

***** 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.

@berkdeniz 9 лет назад

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

@iCanHazTwentyLetters 9 лет назад

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.

Over the course of time I have reviewed these videos and learn each time. Mathematics is one of those things that we can’t live without. Long range shooting is a mathematical lesson that can be mastered with these answers. Hats off to Rex for the reviews. I’ve introduced some of my friends who are big time game hunters to these videos especially the optics

@charlesludwig9173 5 лет назад

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.

@rkba4923 6 лет назад

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.

@nicholasscholten4838 6 лет назад

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.

@saltychristian2528 4 года назад

Thank you for the clarification.

@michaelbrininstool4515 2 года назад

or 25.4 millimeters per inch

@rontate7719 7 месяцев назад

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..

@reinisgailitis 2 года назад

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!

@rmcmc5 9 лет назад

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!

Throughout this series, I've seen a lot of questions about what Rex did, or how he learned all of this stuff. Is he an engineer, etc.? Maybe this has been answered, it takes enough time to watch the videos let alone reading every comment... But anyway, there is another clue in this video, how many shooters do you know who have a page in their dope book titled Soviet Vehicle Dimensions? ...complete with SCUD Missile measurements?

@21jg130 8 лет назад

For target size in inches to work out Distance in Yards I use target size in inches X 27.8 then divide by Mils used this gives the distance in yards

@joshurmetal420 4 года назад

That's how I do it, but I use 27.77 instead on 27.8

@bayman50cal 4 года назад

So 9 inches wide x 27.8 =250.2, divided by 4 = 62.55 yards? I measured the distance and it is only about 50 feet, which should be about 20 yards. What gives?

humor? dude, cubits have been around forever. you must have gone to school in the US.

@AtheHD1 7 лет назад

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 .

@josephsmith7865 8 лет назад

Excellent Video thanks! Just for us Americans we use yards (thanks to the English) so the formula for yards is: 40" (target) X 27.7777 (for yards conversion) / .8 mils =1,388.88 yards or 1,270 meters @ (19.08 minutes ) into video. Cheers.

Will be starting out shooting out to 300 yards at my local range, and farther out when I get good. My rifle is a .308 and I will be getting a SWFA scope when I get the money. I eventually want to shoot out to 1000yds. what do you recommend I get first? I'm on a budget, so it will take a while.

@ericberman4193 9 лет назад

I haven't read all the comments, but it needs to be noted that there's a HUGE difference using FFP (i.e., Front Focal Plane) versus RFP (i.e., Rear Focal Plane) variable power scopes. When you use a FFP variable, you can crank up/down on the zoom and get correct target mil (or MOA) dimensions at all power settings. If you use a RFP variable, those are set to read correctly only at a single power setting (usually the highest power setting available), so you will get an incorrect mil (or MOA) dimensions at any other power setting. If you're using a fixed-power scope, then you don't have a problem of FFP vs. RFP, however you've given up some versatility as regards being able to zoom in/out. Granted, you can get accurate range estimations with either a FFP or RFP variable scope but having to employ the highest power setting on a fairly close-in target when using a RFP variable, might prove more difficult (although not impossible) versus simply being able to dial-down the magnification on a FFP variable to an easier-to-use value. In any case, recticle ranging in either MRAD's or MOA's is a great capacity to have/use.

@binness 9 лет назад

Eric Berman What you say is broadly correct, however NOT all RFP scopes require full power setting, so it is best to look up the specs on your scope. I know you said "(usually the highest power setting available)", but some people won't read that far LOL. ATVBM8

@pepelapiu2004 8 лет назад

@beevang7219 3 года назад

Helpful video!! My question is is it better to use the next mil dot under the crosshair in stead of using your turret to adjust a 400 yd long range shooting? The scope is zero in at 100 yds so the next mil dot would be 200, 300, 400, 500. Would this be easier and on target then using your turret for adjustment? Thank you!

@cameronwilson8484 9 лет назад

Hey Rex love the videos. here is a crazy question for you. What would the formula be to use MOA and using meters for the range and inches for known target size. or meters for both range and target size?

@AdoreYouInAshXI 10 лет назад

This stuff is confusing as hell for me, I got a LWRC R.E.P.R. with a Vortex Viper PST 2.5-10 on it which is a first focal plane and I'm clueless. I'm gonna watch this entire video when I have more time, thanks for uploading.

@dhopper122 4 года назад

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.

@DLN-ix6vf 2 года назад

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.
