Factors: Rifle and bullet accuracy, shooter accuracy, target size, and environment. This zero is actually a 264 yard zero which gives us a 3 inch rise and a 3 inch fall at 300 which marks the end of our MPBR. In other words, I can hold the same sight picture at 50 yards as I do at 100 yards. I knocked the NF off the table ! the US Governement) demanded better. I could acquire pretty easy and still miss only 1 or 2 inches at most. As always, everyone is an individual and what works for most never works for everyone. Using a system like this with a scale reticle appears to me to be the best of both worlds. On the right, an inaccurate projectile could possibly throw rounds far outside our targetable zone and this could result in more misses. So in use, if you are unsure of target distance, hold for the head. I am having no issues consistently hitting the combat effective zone at 300 yards. The other problem is that a 10 yard zero basically makes the rifle unusable for any distance beyond 10 yards. That’s the beauty of the MPBR method, it allows you to tune your trajectory to tailor suit your rifle, your loading, and your target diameter. It maximizes the “point-blank range” where you have to remember a single hold to get hits out to the end of the point-blank range, hence “maximum point-blank range.” As an example, imagine a disk six inches in diameter and I want to hit that disk as far out as possible with one zero. Red dots need to take advantage of a point and shoot zero like any of the other options. It’s easily maneuverable in my home and I don’t have a problem with it. It’s important to get away from the 100-200-300 yard paradigm and examine a zero which allows a more fluid approach to hitting a target at unknown ranges… because remember this, if nothing else; every field target will present at an unknown range. Pick whichever one you want to memorize the holds for. Etc. Check trajectory data for the brand of ammunition you are shooting and adjust the height of your 2-3/4″ 50 yard true zero as necessary so as to produce a dead-on gravity zero at 100 yards. I see no need for them on deer sized game though.

I’ve seen that work out to useful holds with 200y zeros as well as 100s, depending on the scope and load – whatever gets you closest to big round numbers. I think, again in theory, that using the MPBR method would likely put you in the terminal zone as often as other zero’s particularly if our target is at a unknown distance. What ammo and sighting method gives us the highest probability of intersecting the target in spite of environmental conditions and shooter error? You may know about it, or…read more →, 2008... that's the year the ACOG's patent protections have lapsed. With a target at 100 yards and your rounds on target at 50 yards, how well your shots are executed is important. A red dot or BUIS set up with a MPBR zero will assist you in hitting targets of opportunity and at any distance inside your MPBR “box”. Me too, padawan.…read more →. Why, you might ask. Quite a few school hallways Quite a few parking lots. I think my interest is “will best practice methods permit me any statistically significant changes in hit ratios”? It appears that M193 or, even better, a quality defensive 5.56 equivalent such as Hornady 55gr TAP would make the best choice because of the high velocity achieved by 55-grain loadings… but when wind is thrown into the equation the 55-grain stuff makes it more difficult to hit the small targets at the end of its MPBR. Most shots will be in the 50-250 yard range but the occasional shot at 300-500 might take place. Everyone, Trigger Warning! I know if I shoot further than that, I would aim slightly higher due to bullet drop. Hit. At this distance, it’s common to be hitting about an inch or inch and a half low… Now, you can use a slight hold over if the target is particularly small, but most of the time practically sized targets at 25 yards are really large… Groupings are the defining measure of whether an MPBR zero will be effective as inaccurate ammo could possibly land too far away from our target radius to remain useful. This is why you hear people talking (and arguing) about different zeroes such as a 50/200 a 25/300 zero and a 36/300 yard zero. Each rifle and loading will need to be entered in Strelok (or another ballistic calculator) to determine the best zero for your desired target diameter. Hit. good job! 125…………………………+ 1.1 That would reduce your dead on hold to 250 with a 25 yard zero on the 8 inch target above. A standard of being able to hit 4 out of five shots in a 2-in circle at 50 yards transcribes to 4 out of 5 on a 4-in circle at 100. Even the text is real thin, hard to read. The blog is written for everyone who wants to pursue marksmanship and not just for enthusiasts. On the left the accurate projectile strays outside the targetable zone at its maximum ordinate and at the end of the MPBR, but still remains tight and effective. With the gun zeroed to impact a 200-yard target dead center, the same .30-06 will be 1.72 inches high at 100 yards and 7.66 inches low at 300 yards. Point shoot hit. Works well for field shooting, either hunting or battle. The 100-yard zero is just as handy for hold-over points. Shoot at 100, 200, and 300 to know where you are hitting. also depends on how hi above the bore the sight is. Post was not sent - check your email addresses! There is a reason head targets have a 4-in brain zone, and not a 7-9 inch one. Six inches of total vertical resolution seems like a logical choice for an MPBR setup and extends us past our 50 yard / 200 yard zero a bit and is still a fine resolution for engaging defensive targets. As described above, with a 100 yard zero, the bullet’s trajectory just “kisses” the line of sight at 100 yards. Hunters have used this method for a while, but with the popularity of the bullet drop reticle, it has fallen by the wayside in recent years. The 50 yard zero is still going to give you "point blank range" out to 200 or a bit longer. I’d like to see someone skin a cat that has only read about it on the inter-webs, even if they have the best knife belly angle and holding technique they are gonna destroy that future banjo skin. I don’t know how old this is but it’s a nice article. If you estimate the target is at 300-400 yards, holding on the head will ensure rounds drop into the mid torso. However help understand if I missed where do you exactly aim at? I love this scope for that purpose you pointed out in your article so I agree with you 100 percent. Behind the curtain is the true monstrosity that is unchained and unhinged man. Integrating this into my setup… I foresee finalizing my optic equipped rifle with two loadings: XM193 for practice, and Hornady 75 gr HPBT for longer range work. If you’re shooting a red dot on paper at 200 for a competition, are you going to remember under pressure that you have to hold low to get a good hit? The 50 yard zero is a vanilla standard, as it suits almost everyone well… but each rifle or carbine is a unique combination of barrel length / velocity, bullet weight, and shooter. Anything inside of my MPBR I want to aim at and hit without worrying about holdover, hold under, or BDC stadia. I based the data on what I would consider best practice. I struggle to find a use. hunting) then this is fine. Still okay and well inside the vitals on a deer, correct? Pros: Very flat shooting. The acceptable COM is considered to be an 8-in circle. check it out!For more information go to www.triggertimetv.com This is my preferred zero for most big-game hunting in places with a variety of terrain and cover. It doesn’t improve too much on the traditional zero’s, but if it creates a change which makes it harder to miss my mark, I want to try it. An aisle in a Walmart. The other hold is the chest (center of mass). Some I shoot 200 yards and some I only sight in at 50 yards or less. We need knowledge and best practice methodology to ensure hits at any distance. In a self-defense setup, we need to maximize the distance where we will hit our target *without* shot correction. It’s not about what is the most common. Etc. If each rifle setup is unique, then can we do better than a “vanilla” zero for each rig? I think these loading’s can cover all shooting I can ever realistically do. How would I do that? I have them available to download…read more →, Photo Above: Courtesy of Everyday Marksman Really wishing that MUHRINES still had the M16 series of rifles? My green laser goes 100 yards and is really good. Wind can cause us a horizontal shift away from our intended goal of hitting the target. So how do we zero with this wunder method? Placement wound be about e inches below the necklin if I have time to aim. So why not just use the bullet drop marks? The maximum point blank zero here is 259 yards meaning you should be able to hit a 4-inch disk from 0-259 yards with a dead-center hold. With a 50/200 MPBR zero, there is only a 3 to 4-inch difference in point of aim and point of impact from 50 yards to 250 yards. Let’s proceed with some more examples as to why MPBR is worth the trouble over a standard 50 yard zero. A rifle shooting terrible groups at (Say 4 inches at 100 yards) will not benefit from MPBR, as we must consider that at 200 yards the groupings would double to 8 inches, and at 300 the groupings would run around 12 inches. When using magnification, I believe that a 100 yd zero is best since you have the ability to either hold over or dial. Why does this apply to a defensive rifle/carbine? This is a pretty flat trajectory, but the 30-yard zero looses its attractiveness as it drops down to 5.37″ below point-of-aim at 100 yards. THANKS FOR VISITING! Just aim for the vitals and pull the trigger without worrying about bullet drop. Since I want to push the rifles out far, why not study methods that are likely to help me hit targets with a simplified method? I tend to be a man who learns with specifics. I know – it’s “almost” a 50-yard zero, so why not just use 50 and be done with it? Not quite the room clearing, pop out of your car with an AR populace that we seem to discuss online. My advice is to get a ballistic calculator and put in your specific data because there are all sorts of things that will affect the results. If not, then do what correction work is necessary. So why not 4.5 inches up and down if the average head is 9 inches tall for an MPBR of 349 yards!? I like the 50 yard zero for both 16” barrels and 10.5” barrels. Thanks for your input. 100 and 150 are the norms. But flex your brain if you want. Just curious! Unfortunately, 2 weeks ago I removed the then MPBR zero’ed Nightforce to clean my weapon. Success in any of this will depend on training. 200 yard zero should allow for a near dead on hold on a coyote out to 300. And the bullet never lies. The yards vs meters is pretty moot as at 300 its not much difference. Situation dictates… So, again… all you non- lawer, arm chair computer jocks who keep hitting the mag release instead of the safety (great Youtube videos though)… just shut up. I have wondered how many enemy heads showing above a rock have been missed by a soldier aiming center at maximum ordinate range, only to have the round go over the top due to a 300 m zero…a good reason to have your MPBR set carefully. Freestanding in the wind and 3″ at 100 gets fouled up pretty quickly. Hey lothaen if you could help me better understand your method since I agree with the POU behind the method for a AR15 specifically setup for 0-300 yard engagements (the exact POU i’m trying to maximize for my AR15) If I was using my 16″ Match grade Noveske AR15 using 69 SMK (only match ammo I have) according to your information I would zero at 100 yards with 1.7 inch high. Paper does not move and is at a set range. If each rifle setup is unique, then can we do better than a “vanilla” zero for each rig? Cons: Harsh hold unders out to 225 yards. I understand some people won’t see the value of this method and a extra few yards… But if I were a statistician I would be interested in the probability of the bullet and the potential for increased hits via best practice methods for hitting a target at unkown distances. For those that have attended the courses now know that when it comes to your go-to 5.56 caliber carbine rifle that you would pick because it is best suited for all possible scenarios, the 36 yard zero seems to be the perfect fit. Get our new posts sent right to your email! Pros: Somewhat flat shooting.l according to the ballistic calculator. You and Shawn below make some good points regarding the reticle size. as Honeycomb said above. A nation of riflemen would be a great outcome. . Both of you gentlemen have given me new insight. I’d like to offer some counterpoint to the early comments that MPBR techniques are outmoded by quality reticle systems. There is no remembering hold unders, you just aim a little high inside 100 and keep going higher past 100. Best practice appears to be a heavy match bullet out of a rifle length platform to maximize the flat trajectory of the projectile and to take advantage of better accuracy and wind deflection. So I went to a rather busy range last Wed. and decided to set my 300 yard target at 400…read more →, Today was my first day at the range with my simulated 300 meter target. It will cover your shooting out to 400 yards. If the links are broken forgive me I will fix them when I get home. Great thought process. To many paper head shooters now days in my eyes.

It would avoid a person getting confused at the use of terminology when they likely learned to zero using meters, as is the convention in the military to do. You can certainly run the math and print out a dope card with a MPBR zero, but with BDC, I’d want to keep it as simple as possible. dead hold center mass? Knocking the MPBR concept because the military’s 25/300 method is insufficient is missing the point. If you are interested in a more standard AR15 zero method, check out the article linked and visit Soldier Systems. Pros: Your largest hold under is about 1.5” at 125 yards which in my book is point and shoot. It is good advice and I have a few rifles zero’ed for 50 myself, but it’s not the “best zero”. Get our new posts sent right to your email! Light and fast match bullet, or slow and heavy match bullet? In this article, I will be posting some data to share how much the bullet has risen and fallen at different distances with different zeros. Why not a 3.5 inch zero for a 7-inch diameter vital zone!? Also something you aren’t considering. (don’t even get me started on why urban LE qualify at 100m….. ) I resolved this by using my iron sights set on a 50/200 setting with my red dot on about 15m zero. Think of the MPBR as the acceptable vertical resolution where the bullet’s trajectory stays inside the defined size of the target. Has any one had experience with the 36 yard zero? If you had to rely on one zero, what would it be? It is about what is the most efficient. Best practice would be the highest velocity you could reasonably attain for a heavy match bullet which combats light wind. You have to take your gun out and zero it and then verify it at different ranges to see what you prefer. Nice… But why are all the charts “grayed out”? . Thanks for the continued discussion. As the bullet continues to fall, it will fall 2 inches below your line of sight at 259 yards. With any kind of Mil/MOA scale reticle, your initial zero does not affect the usefulness of that scale, except in terms of the maximum range that the reticle subtends. With rifles like the AR15 and the typical ranges of the intermediate cartridge (normally within 300 yards), you can “manipulate” the bullet trajectory. So ultimately, your shooting goals should play into the rifle and its associated setup and upgrades. Wait, it’s not over yet. Torso? That means a dead hold to the middle of the face will *potentially* score head-shots out to darn near 300 yards! If the the shot is both far and time critical, I’m estimating and holding, similar the knock the hat technique. Being able to hold one point of aim and get close hits on targets out to 300 is useful. Goal: increase the probability that the projectile will intersect the target *without* calculations. Colorado Pete: “In the field there are no even-hundred-yard markers.”. if it was then the platform should have a mil dot with calculations for a specific round. It’s not too hard to increase the diameter of the 1.5 MOA reference in your minds eye and you can see a slightly larger diameter of the accuracy circle representation can really put you off target quickly. 3Ish inches over at 300 yards, Please like, share, and 300 to know you.
