For a 10.5 inch barrel, the 50 or 36-yard zero will be ideal. In some situations, did you know that you may not be able to justify shooting someone standing in the same room!!! However, at 250 yards my bullet impact will be 1.2 MOA high (roughly 3.25″). “UP & towards the MAG!”, you can get a good feel for your holds even with something as unscientific as that. But flex your brain if you want. If I have to focus with one eye, I’ll take a scope. I’ve used this method or one like it and it’s pretty flawless on “real” targets. Your data will put me in the ballpark. Meters and yards are so close to each other that i consider both the same. The commenters appear to understand how this works with a 100yd zero. And still works even with higher velocity hunting rounds, or varying target sizes; the method doesn’t care how fast or slow your bullet is, or how big/small the target. ... 50 PM Re: Whats a good site in distance (zero) for a .22-.250?? 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. It’s not about what is the most common. As everyone said its very unlikely for anyone of us to shoot past 25 yards in a self defense situation, but its all academic since I will most likely have my pistol if a self defense situation arises. Ranging and doping the target, even with a BDC reticle, may not happen fast enough and / or you may miscalculate. However help understand if I missed where do you exactly aim at? Of course I could have remembered all that wrong. I always thought / recall it was a 2.5-3 moa round. i was told by a few different people that there is not enough drop at 50 yards to compensate for much. Baby Groot: I am Groot. So in use, if you are unsure of target distance, hold for the head. 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. 100 and 150 are the norms. The Myth: A 25-yard zero puts you “dead-on” at 100 yards.I’ve listened to some pretty amazing ballistic theories over the years but this one is probably the most common. I have the best of both worlds in the ZERO-sphere. Your target, be it defensive or hunting, will present you with an opportune shot for only a few seconds. No physics defying here, just basic ballistics. If the target is near: point and click. 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. If it doesn’t work, I go back three clicks down. where you got info that M193 is considered 1.5 MOA accurate I have no idea. So technically you would have to hold an inch low. Again, I know it is common and accepted as truth, but it defies the laws of physics, and if I could draw a picture and upload here to help explain it, I would. Unfortunately, 2 weeks ago I removed the then MPBR zero’ed Nightforce to clean my weapon. The 50 yard zero is still going to give you "point blank range" out to 200 or a bit longer. Cons: 300 yards is a 9-inch hold over and 400 yards is a 27-inch holdover. In fact, assume a 50 yard zero, the two long lines are 50 yards and the short line is 2 inches. If the average human head is 9 inches x 7 inches + or – an inch. I rarely post .. but stop every so often. So let’s look at heavier match bullets, what benefit do they offer? Get our new posts sent right to your email! All I can say after reading your essay for the fourth time is simply, THANK YOU ! Absolutely respect everyone of you guys who can shoot and have been doing this a long time. The other problem is that a 10 yard zero basically makes the rifle unusable for any distance beyond 10 yards. The use of a match bullet would permit more wiggle room for shooter error. Many many more shooters own and use 16-in or less barreled AR/M platform carbines for defensive purposes than they do rifles. Actually, MRT occurs a little beyond the half-way point – like around 115 for the 200-yard zero, and 170 yards for the 300-yard zero. I miss high or low, I still accomplish my goal, disablement with my hallowpoints. Up to me to do the shooting and fiddle-out the results. 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. So this zero drops quickly past 300 yards. Other ballistic software I've tried (I show one chart as an answer to your previous question) shows that with a 50 yard zero, you will be right ON at 100 yards. That disk could be at 25, 100, 212, or 274.5 yards and a single-center hold would allow me to hit it with no need for holdover. Having a sharp eyeball judgment for your MPBR makes it all come together. 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 My rifle is being set up for the worst case scenario. We don’t need any BDC stadia to be riflemen. For a standard 16” barrel shooting 223/5.56, the 50-yard zero is the flattest shooting and you just need to remember that last 200 yards you start to aim higher… and 300 yards, as long as you can see your target, won’t be impossible to hit with a red dot. Not quite the room clearing, pop out of your car with an AR populace that we seem to discuss online. Thanks!! 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… 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. If they are too close… well then you likely got a head-shot. In other words, I can hold the same sight picture at 50 yards as I do at 100 yards. With a 50 yard zero, your bullet will only be about 1.57 inches above the line of sight at 100 yards and height maxes out just over 2 inches above around 150 yards… An aisle in a Walmart. 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. Also, while we are at it, if you shoot someone more than once or twice, you may not be able to justify yourself…. A solid option for shooting a short-barreled  223/5.56 to 200 yards. Scoffing at a 2.5 minute rated round is kinda arm chair quarter backing too, get out and see what your rifle and ammo actually can do, all the M14’s at my unit did much better than the 2 minute gun standard that they were allowed and that was with ball ammo. If there is … . My caveat: if I had a BDC reticle like Lothaen instead of a scale reticle, I’d probably zero so that my trajectory matched the reticle as much as possible. 1 MOA= roughly 1” at 100 yards (2” at 200 yards.) Past 200 it falls fast. 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 ! TNR’s First Shirt for Pre-Order! There is definitely more than one way to skin a cat, and for s long time I used a 50 yard zero for carbine competitions etc. Point shoot hit. Pros: Will get you out to 300 yards. Largest hold under is 2.75” at 125 yards. You’re also basing data on a 20-in barreled rifle. So why not 4.5 inches up and down if the average head is 9 inches tall for an MPBR of 349 yards!? The maximum bullet arch should no more than 2 inches high above the point of aim. What type of bullet drifts the least? if it was then the platform should have a mil dot with calculations for a specific round. The 50/200 Zero is highly precise at 50 to 200 yards. I will talk about my preferred distance to zero my AR chambered in 5.56. I tend to be a man who learns with specifics. 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. If your only 1/2" off at 100, you'll only be 1/4" off at 50. WTH you want to chase all the old guys away…. Yes? Being able to hold one point of aim and get close hits on targets out to 300 is useful. Quite a few school hallways Quite a few parking lots. 125…………………………+ 1.1 Also something you aren’t considering. Those values match pretty close to a 50yd zero, not a 25. Sorry about that, that’s just the way the chart shows up on my ballistic calculator app. I based the data on what I would consider best practice. 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. Then just a dead hold. The Daewoo K2 is the right arm of the people's republic of best Korea. The goal of a marksman is to study the platform and integrate the best practice findings into his or her shooting. The benefits of match ammo are two-fold: better wind resistance and tighter groupings. 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. The 50 yard zero provides for effective center-mass hits on target at the ranges where a carbine is most commonly used. The 50-yard zero has flatter hold unders than the 36 yard zero out to 200. I so have used this for my 50 years of shooting. Why, you might ask. The grouping was 1.2 inches lower than the point of aim. So at 100 yards, it will strike above your 50/200 zero but only 3 to 4 inches above, and at 250 yards again, it will only strike 3 to 4 inches below your point of aim. A defensive target, once engaged, will not stand up waiting to be shot. BTW on the M193 moa issue .. Frank Proctor uses a 50 Zero at 10 yards, Please Like, Share, and comment. 200………………………….- 0.7, Would be nice to add the Barrel Length, Rifling, Caliber and Grain of the slug. so i held my front sight pretty much exactly where i normally do at the 10, 15, 25 yard. The theory is that, with common big game cartridges, a “zero” at 25 yards will correlate to a second “zero” at 100 yards. Best practice would be the highest velocity you could reasonably attain for a heavy match bullet which combats light wind. The 25-yard zero climbs over the point-of-aim at 25 yards and only reaches approximately 2/10″ before falling back through point-of-aim again at 50 yards. If I am running a scope with a mil or moa etched reticle (i.e. Your rifle is only “zeroed” 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. This gives you a second zero at about 260 yards. 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. So next I whipped up a basic chart to get an idea of what zero at 100 yards I would need to get an MPBR which targets a 6 inch radius. Cons:  Lots of hold under to remember out to 300 yards. So if you want to convert them at 200 yards and you have -4.22 MOA like on the 25 yard zero, will be roughly an 8.83” hold under. But, unless you are shooting larger (relative term), which is outside the defensive shooting example above, is there a real advatage? An RDS with a known size dot can then be used as a rough aiming guide. 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. Great for “Minute of Man”/ silhouette shooting. Today is 4 NOV 20. I’d like to offer some counterpoint to the early comments that MPBR techniques are outmoded by quality reticle systems. As multiple people have pointed out I am overly generous with the accuracy of M193. With time and practice, however, measurable analytics hopefully tend to morph into intuitive action. The acceptable COM is considered to be an 8-in circle. hunting) then this is fine. For the past year, I have been trying to get my head wrapped around best practices for ranging. Once I added a telestock on my 20, I realized it changed the 20 from cumbersome to much improved in the maneuverability dept. Most shots will be in the 50-250 yard range but the occasional shot at 300-500 might take place. If you run a duplex scope (e.g. Light and fast match bullet, or slow and heavy match bullet? In the 20 inch gun, the Mk262 gives us an MPBR for our six-inch diameter target of 284 yards which sacrifices 16 yards from XM193… but the gains in accuracy and wind deflection make it the logical choice for a shooter who wants statistically significant gains on hit probability. the US Governement) demanded better. But this should be a very close estimation. 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. This also means knowing your weapon and using a consistent load. But that’s not the point. With a target at 100 yards and your rounds on target at 50 yards, how well your shots are executed is important. 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. 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. My only question “is the target inside of 300 yards?” Yes? If you clear phone booths and regularly hop out of a car at arms, then choose the appropriate arm. Unless they pay for the SBR stamp or are law enforcement. I am having no issues consistently hitting the combat effective zone at 300 yards. I feel what a lot of people are missing here is this system really came into light when we got into red dots in the military. The article defined the acceptable elevation dispersion as about +/-2″ for relatively small targets of opportunity, with maybe a little room for shooter error built in, then set the zero to maximize the range for that target zone. When zeroing at a closer distance, the bullet will arc like a football. A match projectile on the other hand, which shoots 1 inch or less at 100 yards, 2 inches at 200, and 3 inches at 300 will remain useful inside our maximum point-blank range. At one end we have the longer point-blank range of the 55 grain XM193 and at the other end the heavier 77 Mk 262 at the other. Myself, with a 14.7″ barreled, 5.56mm I’m using a 100 yard zero with a GRSC 1-6x scope. The 50 yard zero provides for effective center-mass hits on target at the ranges where a carbine is most commonly used. I’m 45 years old and grew up in a firearms family. Everything inside 100 yards and past 100 yards you hold high. Both of you gentlemen have given me new insight. 150…………………………+ 0.9 In close, precision is not that big of an issue compared to speed, and the reverse is true at distance, which is why pistols have iron sights (and sometimes red dots) and long range rifles have scopes. Red dots need to take advantage of a point and shoot zero like any of the other options. It might help if one were to use meters instead of yards, which are in fact different from each other. This article will be very simple with lots of pictures. 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. Pros: Everything is a holdover. Why not a 3.5 inch zero for a 7-inch diameter vital zone!? So thanks for the article and let’s row this boat. What an informative, well-written, well-explained essay ! 1" at 50 yards translates to 2" @ 100 yards and so on. Click. I was in the Marine Corps from ’86 to ’90. This system maximizes the distance in which no "hold over" is necessary. But…the bullet does rise? Everyone, Trigger Warning! I can also envision and justify numerous uses of deadly force out to 400 yards, although lesser in frequency. Interesting read. I might like it better than my tried and true 50/200 zero. 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 know – it’s “almost” a 50-yard zero, so why not just use 50 and be done with it? Behind the curtain is the true monstrosity that is unchained and unhinged man. That means that with a 100-yard zero, the bullet will rise ½ inch above line of sight at 50 yards; 1.8 inches above at 100 yards with a 200-yard zero, and 4.7 inches above at 150 yards with a 300-yard zero. 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. Under these constraints, I have no need for a 50/200 or anything approaching that kind of zero. But would your (non-gun) peer’s? Just a quick anecdote on match ammo performance: multiple tests have shown that open tipped match bullets such as the 77 gr and 75 gr jacketed match ammo perform well in a defensive role and show substantial fragmentation: 75gr test and 77gr test. maybe that is a typo? 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. Works with 2MOA and 4MOA dots, and can also be applied with magnified optics. 25………………………….- 1.2 Cons: Not ideal for a red dot zero. cause otherwise that is pretty far fetched. Let’s proceed with some more examples as to why MPBR is worth the trouble over a standard 50 yard zero. 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. 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? We now have better reticles that are even slower to use than duplex reticles, but much more precise. You have to take your gun out and zero it and then verify it at different ranges to see what you prefer. I was quite shocked at what a difference I found between zeroing at 50 yards vs. 45 yards. So, back to the range to MPBR my weapon with the MK 262 clones I reload. And now you’re adding an increase in the acceptable size of the target area. 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. What ballistics calculator app are the screenshots from? In order to improve it, what have you identified as not working as efficiently with current proven methods? I was thinking zero at 200 yards giving me an absolute maximum height of 1.8inches at about 125 yards and -3 at 250 yards. The 50-yard zero has flatter hold unders than the 36 yard zero out to 200. So aiming at a steel circle, you would have to hold off of the target. This may be a great 3g set-up though. Let’s start by expanding upon why we want to ditch the 50/200 zero mantra and see how things go with a 3 inch diameter MPBR: You need a ballistic calculator and some load data. I clicked through from a link posted by Aero Precision. Your blowing up my server. I sight most of my guns in at 100 yards. And a rough estimate of velocity for either a 10.5 or 11.5 barrel. In which case disregard. Point. That has effectively changed our “resolution” to 6 inches where the bullet would stay in the defined target zone. Applying it incorrectly can lead to the issues brought up above. Cutting down to 18 keeps my velocity near peak cartridge effeciency and allows me to pick from several muzzle devices and still stay under 20 inches. from that dead hold? Great article. Typically M193 is considered a 1.5 to 2 MOA load and the 77 grain Mk 262 is considered a sub MOA load. Boom. I can also hold the same sight picture at 150 yards as I did at 100 yards even though the round may hit at 2.7″ low of zero. It is good advice and I have a few rifles zero’ed for 50 myself, but it’s not the “best zero”. Just curious! I am going to trial the method here soon and see how well it works.

Hit. #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. This simplify’s ranging immensely. be justified) beyond 150? 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. That 50 or 100 yard zero for your setup doesn’t stretch out the rifle or carbines maximum useful trajectory. 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. little details like this help noobies like me when we actually go to the range and start to try and put this to practice. You tried to stretch the most out of each gun . For my other AR’s I just simply zero at 100m and either dial or hold over as required. This is a great article. 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. 100 yards 5.5”, 150 yards 6.5”, 225 yards 4.75”, Pros: It’s a 36/200 zero on a 10.5 AR. Everything is a holdover. Remember that standard zero’s are made for shooter convenience and not what’s best for your rifle and projectile combo. You and Shawn below make some good points regarding the reticle size. Thanks for the continued discussion. →, Gun Shops Are Next: CryptoCurrency is for Us, “Said I Never Had Much Use For One. I can’t think of anything I would shoot at that would be missed because my trajectory apex is three inches high. Pros: Your largest hold under is about 1.5” at 125 yards which in my book is point and shoot. The 100-yard zero is just as handy for hold-over points. 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. Let’s face it, it can’t be the same yardage of BDC for varying bullet weights and powder loads etc. I suggest a Criterion Barrels Match Chrome Lined HBAR from Brownells. Considering ammo moa is good but you should also understand that most red dots are 2 to 4 moa. But, you aren’t to far removed from th 50/200 yard zero method of before (re: chest, head, hat). The XM855 would benefit at similar zeros as it will be in between the MPBR of the 77 grain and 55 grain ammo. They’re 1.2″ low at 25. 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. More people shoot 14.5-16 for defensive uses for a reason. In a self-defense setup, we need to maximize the distance where we will hit our target *without* shot correction. Success in any of this will depend on training. I use parallel zero for the laser on my 9mm carbine because in self defense and p close it’s about speed of acquiring the target. For deer hunting I used 6 inch and coyote was 3 inch. Most would like those fancy BDC scopes if they could afford them, but not everyone can. Balance that with your portability needs. 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. To you and me in a court of law I could bring myself to believe it’s possible. Pros: The 25 yard zero on a 16” rifle offers a point of aim point of impact out to 330ish yards. Sight in at 100 yards X inches high in blue for a bullet apex of 3 inches; Above Sig Romeo 5 with Juliet 3x magnifier, Criterion Barrels Match Chrome Lined HBAR, Classic Rifle Review: The Daewoo K2… Korea’s Answer to the AR15, When the Patent Runs Dry: Trijcon’s ACOG Up for Grabs. Make the charts mil or moa based and redo your anslysis. One can expect group sizes to double. Has any one had experience with the 36 yard zero? a few other points, is what a aiming point will equal out to cover at range. The idea behind the zero is that it maximum bullet rise will never be above your target provided you are aiming at the nose, for example. For example my 30-06 is sited in for 2″ high at 100 yards to give it a a zero at about 225 yards with the load I am using. Anyhow….this is the 4th time I have read your essay on MPBR. I’m fairly inexperienced with scopes and all, even after reading a few books and practicing with my own Red Dots, etc. I would venture to say that the average person would be using a 16″ 20″ barrel. Thanks. With that, the military continues to train the 25 / 250 zero method. This is a well written, well conceived article. You stated that your intent was to improve defensive use, therefore it would make sense to use loads or bullets that supported that. Also, a “-“ means hold under and a “+” means to hold over. According to the notes I have written in my USMC marksman notebook I still have today the below info is supposed to be what you end up with…, Range (yds)……Distance above or below the Line of Sight (inches) Colorado Pete: “In the field there are no even-hundred-yard markers.”. It wasn’t until the M855 contract that we (i.e. With an accurate projectile, we can keep our groupings relatively close to our 6 inch diameter target zone. It’s good work on your part. Everyone, Brownells Gears Up to Release “What Would Stoner Do?” Rifles →, Gun Shops Are Next: CryptoCurrency is for Us, “Said I Never Had Much Use For One. Lets start with the 100 yard zero as a reference point. If there were a way to take two groups of shooters and compare hit percentages with traditional zeros and associated shooting theory vs those trained in MPBR methods then that would be the bees knees, but I lack the resources to do such a study. If you were incorrect and your target was closer than you estimated, your projectile would still likely hit the head. Rocket: Try again. I see no need for them on deer sized game though. Ideal for a scoped AR15 that you plan on “dialing in” at any distance. Ranges come in known distance increments and we pick a set distance to zero out of convenience. The true value of this setup is that it helps free you from thinking about your target distance in hundreds of yard increments, and instead it allows you to estimate either near or far. 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. With our example of a 6 inch diameter target and a MPBR of 300 yards, I still want to be able to hit the target in a slight wind. Click. The maximum height of a 50/200 variant can be between 1.5 inches on paper to 2.5 inches. 75………………………….+ 0.6 Using a system like this with a scale reticle appears to me to be the best of both worlds. You will also notice that at 50 yards, the round is only .3″ above zero. The use of match ammo and a match barrel will reduce the influence of bullet inaccuracy in the equation so that’s why it seems to be the “best practice.” The heavy match ammo will also fight the wind to keep you from getting pushed off the head or chest from a light 5mph wind. More velocity always helps, it never hurts. A 25 yard zero yields roughly a 1/2" hold over at 10 yards, but will be POA/POI at 25. Hit. If the links are broken forgive me I will fix them when I get home. 175…………………………+ 0.3 That’s correct. What methods can we use to ensure best practice? At 50 yards, the hold under is minimal and will not be noticeable to most shooters. Ever shoot on your side? This eliminates the gains of our MPBR since many of these shots will escape our defined target zone due to simple inaccuracy. 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. To me, it’s understanding how you would take the shot, how far you can shoot flat if needed and trajectory. What ammo and sighting method gives us the highest probability of intersecting the target in spite of environmental conditions and shooter error? MPBR is a zero scheme that is unique to your rifle and loading. The blog is written for everyone who wants to pursue marksmanship and not just for enthusiasts.
