An aisle in a Walmart. As a police officer in a mainly urban setting, my likely engagement distance ranges from contact distance to not much more than 50m with the average distance being well under 25m. Ever shoot on your side? 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. 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. How does this train of thought match those who’ve already trained this way for so long, like myself a 12yr veteran, US Army Infantry? Still okay and well inside the vitals on a deer, correct? My point is that you are going to what seems to be an older method of aiming that favors speed over precision, though maybe not by much. Besides, even if you have found the perfect system to skin that Cat you’ll still mess up it’s hide if you’re not practiced at that way of cat skinning. Again, with easy-to-understand math. 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 Am Not a 1 MOA Shooter… and I Don’t Have To Be. One decision – is the target with my MPBR or not? A 9mm carbine will shoot pretty flat up to 50 yards then start to drop. Enjoyable read, good info. If they are too close… well then you likely got a head-shot. and i get it if you want to get all tight up about 2 MOA dots, round capabilities, variances wtf-ever then go for that. A defensive target, once engaged, will not stand up waiting to be shot. Paper does not move and is at a set range. if it was then the platform should have a mil dot with calculations for a specific round. Again, i am experimenting with the zero myself… but this variation of maximum point blank range should really help shooters get the most out of their rifle and projectile combo. The 50 yard zero is still going to give you "point blank range" out to 200 or a bit longer. I don’t know if your optic allows 1/2 minutes or 1/4 minutes, or perhaps its in MILS, but get as close as you can to a click. This article is for people who are new to firearms and need some data to help zero their rifle, or for people who donât know about the different rifle zeroes and trajectory. With rifles like the AR15 and the typical ranges of the intermediate cartridge (normally within 300 yards), you can âmanipulateâ the bullet trajectory. Never rely on a ballistic calculator, rely on the data your rifle gives you from actually shooting! Nice work. This is a well written, well conceived article. some cross hairs o, irons or dot may cover 4 inch at X range,.. thats not much “wiggle room” I would also be interested how you would justify a 270 yard shot in a self defense situation. 1 MOA= roughly 1â at 100 yards (2â at 200 yards.) What an informative, well-written, well-explained essay ! It will cross your line of sight twice; once at where you zeroed it, and once again when the bullet starts to drop. If you clear phone booths and regularly hop out of a car at arms, then choose the appropriate arm. For example my 30-06 is sited in for 2â³ high at 100 yards to give it a a zero at about 225 yards with the load I am using. Seems to work reasonably well. I can also envision and justify numerous uses of deadly force out to 400 yards, although lesser in frequency. No physics defying here, just basic ballistics. Cons: None out to 200 yards. If it doesn’t work, I go back three clicks down. I am with you on the MPBR method. My green laser goes 100 yards and is really good. It might help if one were to use meters instead of yards, which are in fact different from each other. The Myth: A 25-yard zero puts you âdead-onâ at 100 yards.Iâve listened to some pretty amazing ballistic theories over the years but this one is probably the most common. #2, Choosing your zero only by looking at what distance you are going to use primarily, such as only shooting threats at 25 or 50 yards, and choosing to zero accordingly, fails to take into account the whole concept of keeping a shooting trajectory flat and easy to use, because it only focuses on the close half (Also completely forgetting about height over bore sight considerations as well. Freestanding in the wind and 3″ at 100 gets fouled up pretty quickly. Thanks. Obviously I have no way to fully test that without a study, but with modern ballistic tools I was able to measure and examine wind drift, accuracy, and bullet drop and Overlay them on a b27 to see which zero and setup would keep me in the target zone the longest and resist accuracy issues and environmental factors. Success in any of this will depend on training. I would venture to say that the average person would be using a 16″ 20″ barrel. Pros: Very flat shooting. 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. In the field there are no even-hundred-yard markers. 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. precision rig) I zero at 100 meters and dope from there. For a longer zero, you need to step it a few more times. Use a ballistic calculator app such as Strelok! In some situations, did you know that you may not be able to justify shooting someone standing in the same room!!! 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. Hit. I found that between a 15 to 25m zero was good for this but put me way off at 100 for qualification. Anyhow….this is the 4th time I have read your essay on MPBR. Many many more shooters own and use 16-in or less barreled AR/M platform carbines for defensive purposes than they do rifles. In the recent carbine courses we have discussed various yard lines to zero your rifles along with the pros and cons of each yard line. 100…………………………+ 1.0 XM193 makes a good substitute as your holds would be the same, but the wind may knock you off target without some very light wind correction. Hit. So a 50 yard zero on a 16inch 5.56/223 barrel is point and shoot out to 200 yards and everything after that is a holdover. My rifle is being set up for the worst case scenario. 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. dead hold center mass? Cons: Harsh hold unders out to 225 yards. Great thought process. 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. Horse-shoes & handgrenades… But that’s not the point. The XM855 would benefit at similar zeros as it will be in between the MPBR of the 77 grain and 55 grain ammo. How would I do that? 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. Unfortunately, 2 weeks ago I removed the then MPBR zero’ed Nightforce to clean my weapon. With an accurate projectile, we can keep our groupings relatively close to our 6 inch diameter target zone. The 50-yard zero has flatter hold unders than the 36 yard zero out to 200. At this distance, itâs 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⦠50 yard zero acog, acog 50 meter zero, acog 50 yard site in, acog adjustment clicks at 25m, acog chevron 50 yard, acog ta31rco-m4 zero, acog zero 50 yards, acog zero instructions, best acog for sig 556, sighting in acog in yards, ta31f 50 yard zero, trijicon acog 50 yard zero, trijicon zeroing target, zeroing and acog at 50 yards muzzle…………………..- 2.5 Right now I run a Razor which has 1/2 minute crosshairs, but other shooters may not run the same so you guys are right the reticle needs to be considered in this sighting method. With a target at 100 yards and your rounds on target at 50 yards, how well your shots are executed is important. A solid option for shooting a short-barreled  223/5.56 to 200 yards. I believe a .223 75-77 gr load from a 18-20 inch barrel out of 1/7 or 1/8 twist would be optimal. 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. Let’s zero so the maximum ordinate of our XM193 is 3 inches above the line of sight. Interesting. I suggest a Criterion Barrels Match Chrome Lined HBAR from Brownells. Rocket: Try again. Most shots will be in the 50-250 yard range but the occasional shot at 300-500 might take place. As long as you do your part and shoot well, the higher accuracy and better wind resistance will reduce flyers which could land outside our intended target. More velocity always helps, it never hurts. 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. 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. Cons:  Lots of hold under to remember out to 300 yards. “UP & towards the MAG!”, you can get a good feel for your holds even with something as unscientific as that. What I have found (based on comparison of several ballistic calculators and real-world experience at both indoor and outdoor ranges) is that a 45-yard zero will give you a very good “point blank” range – the bullet will never be more than 2.8″ high (145-170 yards) and doesn’t drop below 2.8″ until you reach 300 yards. →, Gun Shops Are Next: CryptoCurrency is for Us, “Said I Never Had Much Use For One. If you estimate the target is at 300-400 yards, holding on the head will ensure rounds drop into the mid torso. When this is added to your drop, the zero hold difference becomes even shorter. I can’t think of anything I would shoot at that would be missed because my trajectory apex is three inches high. The value of PBZ as you say is to reduce the amount of thinking by the shooter in a stress situation, by maximizing the distance within which one doesn’t have to apply elevation correction. Three inches of rise and fall (for a total of 6 inches of vital zone) gives us a great starting point for hitting hiding, peeking, or partially exposed targets. If your only 1/2" off at 100, you'll only be 1/4" off at 50.

With my tri-sight set up I can zero in the red dot and laser at 50yrds for close in shots and the scope at 100-200yds for the long shots.DONE ! However, and this is going to ruffle feathers as there are some absolutely accepted terms in this community, I quickly lose faith in any expert that uses the term “bullet rise” and believes in it. On the right, an inaccurate projectile could possibly throw rounds far outside our targetable zone and this could result in more misses. 100 and 150 are the norms. Your rifle is only âzeroedâ at the range you zero it at (50 yards, 25 yards, 36 yards, 100 yards) and the second distance will be a close guestimate until you confirm it at range. Just curious! Range Gear: Lynx Defense Pistol Range Bag, Magpul Introduces New MBUS Pro LR with BDC adjustment, A Parable for the Poors: Palmetto State Armory v.s. Baby Groot: I am Groot. Using a system like this with a scale reticle appears to me to be the best of both worlds. When zeroing at a closer distance, the bullet will arc like a football. If I have to focus with one eye, I’ll take a scope. I sight most of my guns in at 100 yards. We want the highest probability of hitting a head, torso, or half exposed limb. I rarely post .. but stop every so often. So the 50/200 yard zero allows you to put the dot on the target at any range from CQB to 250 yards (might go out to 300 depending on your barrel and ammo selection) without having to use hold overs or hold unders. As far as hitting the terminal zone itself, what’s to say that, at a unkown range, you might estimate the distance incorrectly and you drop rounds too low? Up to me to do the shooting and fiddle-out the results. 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. And with Nikon’s Spot On app with ballistic and field charts calculator for this scope it’s a breeze. 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. The MPBR method you outlined above has been used by hunters for decades because they had scopes with crosshairs and no dots or BDCs. They will be hiding, returning fire, and they will present a small target for the shooter. 300 yards, aim for the head for a COM hit. I think BDC on most scopes are overrated, very hard to see (unless you have a high quality pricey scope) and may not be totally accurate. I have been shooting an array of pistols and rifles with iron sights for 54 of my 65 years. Your data will put me in the ballpark. Ergo my challenge is to take this method and apply it in the competition world and see how it works out.
