Range Estimation Methods in Rifle Shooting
.
By: David Watson
.
Putting aside technology in the form of laser rangefinders and rangefinding reticles, there are several methods available to the shooter for range estimation.
.
Techniques such as the known-distance comparison, bracketing, map method, and short-distance method allow the shooter to make a structured estimate of the range, which is far superior to a flat-out guess.
.
Each of these methods results in estimations, which therefore are subject to inaccuracy and variance, but the strength of these methods is that they can all be used at the same time. This enables the shooter to develop a “composite range” that’s averaged from the results of all the methods. With practice, this does provide a reasonably accurate representation of real range.
.
The Known-Distance Method
.
The known-distance method takes a distance that is visually very well known to the shooter, such as a football field or the distance between power poles, etc., and then asks how many times that known distance fits into the space the shooter is trying to measure.
.
The known distance can even be the viewed distance to the target at the 100 yard/meter shooting mound. The shooter may decide that there are two football fields or eight power poles that can fit between their location and the target, thus yielding an estimation of the range.

Or, you can make this simpler. I virtually never shoot over 50 yards, mostly under 30. There, range issue solved! :laugh: 'Minute of squirrel" is my accuracy goal, whether its self defense or hunting. My self-defense practice is very close range, and in the areas I hunt visibility is rarely over 50 yards, so there's really no need to go to a range and practice at 100 yards or more.

Well that's one way to solve the problem. I very rarely nowadays shoot over 100 yards which is point blank range for my .22 magnum rifle but some guys like the challenge of sending rounds 1000+ yards. I have never tried it but would like to one day.

I like your reference to "minute of squirrel!" :biggrin: While your hunting environs and the type of hunting you do may not require expertise beyond 100 yds, many other hunting situations do. My last elk hunt in the Montana Rockies required that you be prepared to shoot at distances from less than 50 yds to at least 500 yds. In our group we harvested 4 elk. The shortest was at about 35 yds, the longest at just shy of 600 yds. Learning to shoot at greater distances will usually tighten up your groups at 100 yds also. It did for me. Having alternate range-finding skills for when your laser range finder fizzles means you can continue your hunt and not just head back to camp...
 
Why make things any harder than they already are? Once I sight-in a rifle I will remember what it can and can't do at any particular distance. I don't like using a rifle (or a carbine) at what I consider to be handgun distance; and it never fails to annoy me whenever someone sets up on the 25 yard line with his AR16 and begins blasting away. (Like last weekend!) I have to wonder: Where is the guy's pride? Two methods I use to put my own shots, 'in there' are (1) to look for objects of known size along my line-of-sight and mentally compare them to the known ballistics of whatever cartridge I'm using; and, at distance, (2) I'll try to recover quickly enough to see my bullet strike so that I'll be better able to line up a next shot if need be. Of course, the easiest way to work with a rifle at any distance is to simply, 'buddy up' and use a spotter. (Besides, the more long range rifle shooting you do the better you become at it.)

That would be an AR-15 (and not AR16) and there is a reason for a 25-yard (or 50-yard) zero, if you actually understand anything about .223/5.56 ballistics. A 50-yard zero is preferred for a fighting rifle. You can zero an AR-15 at 50 yards on a 25-yard range target, if you know what you are doing. For a fighting rifle, you just zero it once at 50 yards and just know where to hold it.
 
I zero my rifle at 50 yards. I also practice with my rifle from 0 - 100 yards. Then I practice long range (250- 1000 yards).

I cheated and used a range finder...o well...dried food cans (little bigger than coffee cans) at 800 yards using 7x zeroed at 50 yards.

Wow! You certainly seem to know it all. I'm impressed. (Not!) Not one of the long distance rifle ranges I shoot at allows 25 yard rifle sight-in. Which tell this Range Safety Officer a lot about what you really know about rifle shooting. (Not enough!) Next time you respond to something I post, do both of us a favor and try not to be so pedantic. I'm sure we both know that you're not half as sophisticated as you pretend to be; but congratulations on the AR15 part of your reply. (That's the part you got right!)

Another thing: Who told you that a 50 yard zero is preferred on a, 'fighting rifle'? (It took some kind 'a moxie to post that on anybody's gun board! MPBR estimation is how we usually do it.)

The standard US Army M4 zeroing procedure is at 25 meters.
 
MPBR, isn't that what the military refers to a BZ0 (battle zero), just sets up the rifle for a 25/300 yard zero....which changed to IBZ0 (improved battle zero) which is the 50/200 for 5.56?

The current Army policy is to normally zero rifles to 25/300 meters unless the unit is deploying specifically to an urban environment where the 50/200 meter zero is used. That's on page 5-19 of Army FM 3-22.9, CH 1.


*5-49. For a unit deployed to an urban area, many engagements happen at 200 meters or closer. Out to
200 meters, a 200-meter zero keeps the point of impact closer to the point of aim than a 300-meter zero.
*5-50. The 200-meter zero is not an alternate to the 300-meter zero; rather, it is a supplemental zero. The
standard 300-meter zero will continue to be used when units are conducting standard rifle qualification or
when units are deploying to an area where most engagements occur at distances greater than 200 meters.
*NOTE: 200-meter zero procedures mirror those of standard zero procedures, with the
exception of the target offsets. See Appendix F for more information about preparing 200-meter
zero target offsets for various sights.


In regards to zeroing an AR-15 - bofh is generally more correct than Arc Angel - unless a person expects to do most of their shooting between 50 and 200 meters.

I know that there are long-distance rifle ranges that do not allow for 25-yard sight-in, but that wasn't the point of discussion. Do you have people shooting AR-15s at 25-yard targets or not? If not, why did you bring it up in your first post? If you do, then why dismiss it in your second post?

The 50-yard zero question has already been addressed: BZ0 vs. IBZ0. See Maximum Point Blank Range and the Battlesight Zero and BATTLE SIGHT ZERO (BZO): WHO HAS IT RIGHT?.

:wacko: No, no, no! In your exuberance to prove yourself correct in another one of these stupid IGF arguments, you’ve got it all bassackwards. (Again!)

Do you drink before you write this stuff, or what? How about a reading comprehension problem? Is it difficult for you to be coherent; or, perhaps, even rational? You really puzzle me. Maybe you simply enjoy getting into arguments on internet gun forums? (There ARE people like that - Yes!) You and your buddy, the firefighter, do this all of the time. In fact this sort of confrontational, rather than helpful, behavior is what I’ve come to expect from the both of you.

Look, I’m an instructor; and people have always told me that I’m very good at the job. I’m quite different from you; and I use a different approach. Me? I’d much rather help someone to shoot, or handle a gun better than to argue. Unfortunately, however, it’s not a perfect world, and internet gun forums have a way of too often become like rumpus rooms for people who (When you come right down to it.) are socially maladjusted and/or in love with, both, themselves and violence. (I’ve learned that this is the price you have to be willing to pay for being on somebody else’s internet gun forum.)

Consequently I’m going to try to make this my final reply to the both of you; and I will be as brief as possible. Here we go: First, you seem to be much too anxious to find fault with something I've said. In your quest to prove me wrong you focus on minutia, and (worse) actually twist what I say and put words in my mouth. What you say I’ve said, and what I actually said are TWO DIFFERENT THINGS.

Were you brighter (or, perhaps, more fair-minded) you wouldn’t attempt to connect my separate comments, and parse together separate and distinct remarks that were never intended to be directly associated. In this case what you are trying to make me say is NOT what I actually said. It’s just that with you an argument seems to matter more than the truth.

Now, try to follow what I’m saying: (Ready?) There is no direct association between my two separately quoted remarks. My first remark refers to a visit to one gun range, on one particular day, and alludes to the behavior of someone whom I encountered there; and, the second remark refers to my own shooting, at other times, under different circumstances, at other gun ranges. (Got it?)

Stop quibbling! It’s neither honest, nor fair of you to attempt to put your words, and the erroneous conclusions you’ve reached (or woven) into my mouth. I didn’t do anything like that to you! Let me spell things out for ya, sport: I don't go onto anybody’s internet gun forum in order to argue; and if I don’t have something genuinely useful to say then I’m old enough and wise enough to know better than to post, ‘crap talk’ that adds nothing useful to the discussion.

You are, I think deliberately, misleading the people who read this thread. (1) I’m not talking about using a short barreled carbine inside an urban combat environment; but, quite apparently, you are! (2) Beyond what the author of your referenced article reluctantly admits: I DO HAVE THE MEANS TO ESTABLISH AND WORK EFFECTIVELY WITH MORE GENUINELY USEFUL MPBR’s.

Neither have I contradicted anything I previously said. YOU HAVE ASSUMED a relationship between separate remarks that was neither implied, nor intended. (Probably because you’re anxious to win another one of your internet gun forum arguments!)

Even the author of the flimsy article you reference realizes that a, ‘50 yard’ zero isn’t anywhere near as useful as a legitimate MPBR zero; but, still, you insist upon flaunting it. I’ll grant that lowering a carbine’s zero by one or two inches might be an advantage in CQB urban combat; but in my world of considerably more sophisticated and demanding marksmanship, 50 yard zeros mean nothing - Nothing!

In today’s world of combat pistolcraft and urban carbine warfare it’s not necessary to adjust either pistol or carbine sights for shooting at probable ranges of 50 to 80 yards. What for? Surely even you must realize that any such adjustment would be useless to an average marksman, anyway - Right! In so many words the author of your quoted articles even says as much before he drones on about how things could be better if more shooters were able to sight-in on 300 + yard ranges. (You do realize this; don’t you?) Know what? The author is correct! It’s you who are wrong.

That’s it. I’m not going to argue with you any further. You could have learned a lot from me, pal. I’ve trained any number of outstanding rifle marksmen, including one exceptional, decorated Army sniper whose FBI father has repeatedly attributed his son’s battlefield success (at least in part) to the riflery training I gave the boy when he was in his late teens. (Furthermore, from what his father has told me, so did this young man’s B-4 instructors at Fort Benning, GA where he, afterwards, went on to train. His dad said that all the sniper school range instructors wanted to know where his son had learned to shoot like that! They were amazed at what I had taught the boy about long range rifle marksmanship! True story! No internet gun forum BS.)

To expand upon what I’ve already said: I’ve been shooting all different sorts of guns, now, for more than 50 years. I’ve also spent my entire life as an outstanding marksman; and, you may believe me, I’ve received the praise and numerous accolades to prove it, too. You could have learned a lot from me, pal; but, now, that’s never going to happen. (Won’t be my loss!) :no:



NOTE: Firefighterchen, I spent a little time looking around the internet. Here’s a number of underlying reasons why, even with the improvements in modern primer chemicals, it remains a good idea to clean a dirty gun barrel once; and, then, clean it again two or three days later - A practice a lot of the expert marksmen I used to regularly shoot with followed for many years; and I suspect there are quite a few of us left who still do. (Although, as I’ve previously said: I truly don’t care how any of you clean your guns.)

Whether the primers were potassium chloride, or lead styphnate didn’t matter. The only barrels we didn’t clean twice, like this, were the ones that contained deposits of molybdenum disulfide. These barrels did tend to be more accurate; however, raw moly is both more wearing, and hygroscopic. Consequently, moly-coated barrels invariably tended to wear out faster. That’s it, kids! I’m done with this nonsense, now. If I decide to stay on the board it’s onto the Ignore List for the both of you.
 
Good Lord. My posts #6 and #12 were consistently in response to your posts #5 and #8. My post #6 quoted your #5. Your post #8 quoted my post #6. Now you claim that there is no direct association between your posts #5 and #8. Nice try.

I understand that you got confused on the issue at hand: fighting rifle vs. long-range rifle. All I pointed out was that an AR-15 is commonly zeroed at BZ0 or IBZ0, if it is used as a fighting rifle. That zeroing can be done at short ranges, which was my simple explanation for your initial comment about people shooting an AR-15 at 25 yard targets.

How about investing less emotions in your posts. There is no reason for you to blow a gasket over someone pointing out a mistake in one (or two) of your posts.

PS: Your response to Firefighterchen should go in the right discussion thread.

PS: If you think that I don't value your expertise, you are wrong. Based on your comments regarding Glocks, I did remove the extended magazine release and the extended slide stop lever from all my Glocks. However, I don't take every post at face value and reconfirm them with other sources.
 
Do you mind sharing your real name Arc? If anonymity is your game, all your personal stories will just be gun forum BS.

I find it interesting...those that "Ignore" the people who would be considered "my crew" tend to get banned frequently...just an observation.

On the AR-15 Car we have a Red-Dot @ 25 yrds, on the full size we use 25, 50 yards via a mil-dot sight.
How many folks come here to vent or to appear to be much better than they may be to make up for a feeling of being inadequate?
Why are we trying to one up each other? This was a good thread and went south, WHY?

Howdy,

I need a popcorn eating smiley for this thread.

Back in the "Day" my first M-16 was an old A1 rifle complete with triangle handguard and a 1-12 twist barrel.

It had the old dual aperture rear peep sight, a big aperture was for close distance combat shooting and the smaller one was for distance shooting.

IIRC ( it's been over 30 years and I've been to 2 dozen small arms schools while in the military ) we zeroed the rifle at 25yds with the big aperture and this would put us on target with the the big aperture at 100yds and the small aperture at 300yds.
