Why You CANNOT Rely on the MV Printed on the Ammo Box!
When figuring out your come-ups with a ballistics solver or drop chart it’s “mission critical” to have an accurate muzzle velocity (MV). When shooting factory ammo, it’s tempting to use the manufacturer-provided MV which may be printed on the package. That’s not such a great idea says Bryan Litz of Applied Ballistics. Don’t rely on the MV on the box, Bryan advises — you should take out your chrono and run your own velocity tests. There are a number of reasons why the MV values on ammo packaging may be inaccurate. Below is a discussion of factory ammo MV from the Applied Ballistics Facebook Page.
Five Reasons You Cannot Trust the Velocity on a Box of Ammo:
1. You have no idea about the rifle used for the MV test.
2. You have no idea what atmospheric conditions were during testing, and yes it matters a lot.
3. You have no idea of the SD for the factory ammo, and how the manufacturer derived the MV from that SD. (Marketing plays a role here).
4. You have no idea of the precision and quality of chronograph(s) used for velocity testing.
5. You have no idea if the manufacturer used the raw velocity, or back-calculated the MV. The BC used to back track that data is also unknown.
1. The factory test rifle and your rifle are not the same. Aside from having a different chamber, and possibly barrel length some other things are important too like the barrel twist rate, and how much wear was in the barrel. Was it just recently cleaned, has it ever been cleaned? You simply don’t know anything about the rifle used in testing.
2. Temperature and Humidity conditions may be quite different (than during testing). Temperature has a physical effect on powder, which changes how it burns. Couple this with the fact that different powders can vary in temp-stability quite a bit. You just don’t know what the conditions at the time of testing were. Also a lot of factory ammunition is loaded with powder that is meter friendly. Meter friendly can often times be ball powder, which is less temperature stable than stick powder often times.
3. The ammo’s Standard Deviation (SD) is unknown. You will often notice that while MV is often listed on ammo packages, Standard Deviation (normally) is not. It is not uncommon for factory ammunition to have an SD of 18 or higher. Sometimes as high as 40+. As such is the nature of metering powder. With marketing in mind, did they pick the high, low, or average end of the SD? We really don’t know. You won’t either until you test it for yourself. For hand-loaded ammo, to be considered around 10 fps or less. Having a high SD is often the nature of metered powder and factory loads. The image below is from Modern Advancements in Long Range Shooting: Volume II.
4. You don’t know how MV was measured. What chronograph system did the manufacturer use, and how did they back track to a muzzle velocity? A chronograph does not measure true velocity at the muzzle; it simply measures velocity at the location it is sitting. So you need to back-calculate the distance from the chrono to the end of the barrel. This calculation requires a semi-accurate BC. So whose BC was used to back track to the muzzle or did the manufacturer even do that? Did they simply print the numbers displayed by the chronograph? What kind of chronograph setup did they use? We know from our Lab Testing that not all chronographs are created equal. Without knowing what chronograph was used, you have no idea the quality of the measurement. See: Applied Ballistics Chronograph Chapter Excerpt.
5. The MV data may not be current. Does the manufacturer update that data for every lot? Or is it the same data from years ago? Some manufacturers rarely if ever re-test and update information. Some update it every lot (ABM Ammo is actually tested every single lot for 1% consistency). Without knowing this information, you could be using data for years ago.
CONCLUSION: Never use the printed MV off a box of ammo as anything more than a starting point, there are too many factors to account for. You must always either test for the MV with a chronograph, or use carefully obtained, live fire data. When you are using a Ballistic Solver such as the AB Apps or Devices integrated with AB, you need to know the MV to an accuracy down to 5 fps. The more reliable the MV number, the better your ballistics solutions.
If you buy one book about Long Range Shooting, this should be it. Based on sophisticated testing and research, this 356-page hardcover from Applied Ballistics offers important insights you won’t find anywhere else. Modern Advancements in Long Range Shooting – Volume II, the latest treatise from Bryan Litz, is chock full of information, much of it derived through sophisticated field testing. As Chief Ballistician for Berger Bullets (and a trained rocket scientist), author Bryan Litz is uniquely qualified. Bryan is also an ace sling shooter and a past F-TR National Champion. Moreover, Bryan’s company, Applied Ballistics, has been a leader in the Extreme Long Range (ELR) discipline.
AUDIO FILE: Bryan Litz Talks about Modern Advancements in Long Range Shooting, Volume 2. (Sound file loads when you click button).
Volume II of Modern Advancements in Long Range Shooting ($39.95) contains all-new content derived from research by Applied Ballistics. Author Bryan Litz along with contributing authors Nick Vitalbo and Cal Zant use the scientific method and careful testing to answer important questions faced by long range shooters. In particular, this volume explores the subject of bullet dispersion including group convergence. Advanced hand-loading subjects are covered such as: bullet pointing and trimming, powder measurement, flash hole deburring, neck tension, and fill ratio. Each topic is explored with extensive live fire testing, and the resulting information helps to guide hand loaders in a deliberate path to success. The current bullet library of measured G1 and G7 ballistic coefficients is included as an appendix. This library currently has data on 533 bullets in common use by long range shooters.
Bryan tells us that one purpose of this book is to dispel myths and correct commonly-held misconceptions: “Modern Advancements in Long Range Shooting aims to end the misinformation which is so prevalent in long range shooting. By applying the scientific method and taking a Myth Buster approach, the state of the art is advanced….”
Bullet Dispersion and Group Convergence
Part 1 of this Volume is focused on the details of rifle bullet dispersion. Chapter 1 builds a discussion of dispersion and precision that every shooter will benefit from in terms of understanding how it impacts their particular shooting application. How many shots should you shoot in a group? What kind of 5-shot 100 yard groups correlate to average or winning precision levels in 1000 yard F-Class shooting?
Chapter 2 presents a very detailed investigation of the mysterious concept of group convergence, which is the common idea that some guns can shoot smaller (MOA) groups at longer ranges. This concept is thoroughly tested with extensive live fire, and the results answer a very important question that has baffled shooters for many generations.
Part 2 of this Volume is focused on various aspects of advanced hand-loading. Modern Advancements (Vol. II) employs live fire testing to answer the important questions that precision hand loaders are asking. What are the best ways to achieve MVs with low ES and SD? Do flash hole deburring, neck tension, primer selection, and fill ratio and powder scales sensitivity make a difference and how much? All of these questions are explored in detail with a clear explanation of test results.
One of the important chapters of Part 2 examines bullet pointing and trimming. Applied Ballistics tested 39 different bullet types from .224 through .338 caliber. Ten samples of each bullet were tested for BC in each of the following configurations: original out of the box, pointed, trimmed, pointed and trimmed. The effect on the average BC as well as the uniformity in BC was measured and tabulated, revealing what works best.
Part 3 covers a variety of general research topics. Contributing author Nick Vitalbo, a laser technology expert, tested 22 different laser rangefinders. Nick’s material on rangefinder performance is a landmark piece of work. Nick shows how shooters can determine the performance of a rangefinder under various lighting conditions, target sizes, and reflectivities.
Chapter 9 is a thorough analysis of rimfire ammunition. Ballistic Performance of Rifle Bullets, 2nd Edition presented live fire data on 95 different types of .22 rimfire ammunition, each tested in five different barrels having various lengths and twist rates. Where that book just presented the data, Chapter 9 of this book offers detailed analysis of all the test results and shows what properties of rimfire ammunition are favorable, and how the BCs, muzzle velocities and consistency of the ammo are affected by the different barrels.
Chapter 10 is a discussion of aerodynamic drag as it relates to ballistic trajectory modeling. You will learn from the ground up: what an aerodynamic drag model is, how it’s measure and used to predict trajectories. Analysis is presented which shows how the best trajectory models compare to actual measured drop in the real world.
Finally, contributing author Cal Zant of the Precision Rifle Blog presents a study of modern carbon fiber-wrapped barrels in Chapter 11. The science and technology of these modern rifle barrels is discussed, and then everything from point of impact shift to group sizes are compared for several samples of each type of barrel including standard steel barrels.
In today’s feature, Emil Praslick III of Team Applied Ballistics explains how to determine wind direction down range. Praslick, now retired from the U.S. Army, was an 18-time National and 2-time World Champion coach with the USAMU. Emil is consider by many to be one of America’s greatest wind readers — a master when is comes to identifying wind value and direction, and predicting wind cycles.
Video ONE: Determining the Direction of the Wind
Key Point in Video — Find the Boil
Emil explains how to determine wind direction using optic. The method is to use spotting scope, riflescope, or binoculars to look for the “Boil” — the condition in mirage when the light waves rising straight up. The wind will generate that straight-up, vertical boil in your optics when it is blowing directly at you, or directly from your rear. To identify this, traverse your scope or optics until you see the boil running straight up. When you see that vertical boil, the direction your optic is pointing is aligned with the wind flow (either blowing towards you or from directly behind you).
Video TWO: The No Wind Zero Setting
In this second video, Emil defines the “No-Wind Zero”, and explains why competitive shooters must understand the no-wind zero and have their sights or optics set for a no-wind zero starting point before heading to a match. In order to hit your target, after determining wind speed and direction, says Emil, “you have to have your scope setting dialed to ‘no wind zero’ first.”
Coach of Champions — Emil Praslick III
SFC Emil Praslick III, (U.S. Army, retired) works with Berger Bullets and Applied Ballistics. Emil served as the Head Coach of the U.S. National Long Range Rifle Team and Head Coach of the USAMU for several years. Teams coached by Emil have won 33 Inter-Service Rifle Championships. On top of that, teams he coached set 18 National records and 2 World Records. Overall, in the role of coach, Praslick can be credited with the most team wins of any coach in U.S. Military history.
Competing at Camp Atterbury in mid-July, Paul Phillips of Team Applied Ballistics won the 2018 NRA Extreme Long Range (ELR) Championship. Shooting a McMillan-stocked .416 Barrett rifle with 550-grain Cutting Edge Bullets, Phillips won convincingly, finishing with 62627 points. Runner-up, shooting a .375, was Chase Stroud (56744 points).
Paul Phillips (holding rifle) with wind coach/spotter John Droelle. Rifle components included: McMillan ELR Beast Stock, BAT Action, Bartlein Barrel, Nightforce ATACR 7-35×56 mm scope, Phoenix Precision Bipod. Cartridges shown are similar .416 Barrett rounds used by Derek Rodgers in 2018 K02M event.
Caliber and Cartridge Choice:
Paul Phillips, shooting the .416 Barrett, was the only shooter in the Top Ten running a .416-caliber rifle. There were eight .375-caliber rifles (mostly .375 CheyTacs) and one .338-caliber in the Top Ten. Overall, there were 36 competitors registered for the Match, 30 of whom scored points. Fourteen of the 30 scoring competitors, nearly half, shot a .375-caliber cartridge. The .338 (mostly .338 LM) was the next most popular caliber choice.
Course of Fire — Three Extreme Yardages:
The 2018 NRA ELR Event included three stages, at progressively longer yardages: 1500, 1760 (mile), and 1961 yards. At each distance, starting at 1500, the competitors fired five (5) shots at a 36″x36″ steel plate. There were no sighters, practice shots, or ranging shots allowed. This meant the competition put a premium on precise ballistic solutions, and very consistent ammo.
Notable Competitors: There were 36 competitors registered for the match including some big names — David Tubb and Brian Litz. The field included F-Class aces Dan Pohlabel and Jeff Rorer. Capstone Precision President (and former Sinclair Int’l President) Bill Gravatt helped spot for Paul Phillips. Notably, both David Tubb AND his son-in-law Nate Stallter finished in the Top Ten shooting the new .37XC.
Successful Event with Many Sponsors: Shooting Sports USA noted: “Though only the second of these events, the match has experienced a real surge in popularity, well attended… and sponsored by some of the best in the business. Cutting Edge Bullets, Nightforce, McMillan Fiberglass Stocks, Holland’s Shooters Supply, Applied Ballistics, Vihtavouri Powder, and Crosstac, all of whom played a role in Paul’s big win, were also major sponsors of the event. Below is a banner listing all of the match’s sponsors.”
The 2018 King of 2 Miles (KO2M) event took place July 2-4 in Raton, New Mexico. Conditions were very challenging this year, yet three shooters managed to hit the most distant 3,525-yard plate at least once in five shots, a remarkable accomplishment. At that range the bullet was in flight about six seconds.
Robert Brantley of Team Manners Composite Stocks is the new King of 2 Miles. Congrats to Robert and his team-mates. Robert amassed 85178 points, finishing over 20,000 points ahead of runner-up John Buhay. Paul Phillips of Team Applied Ballistics finished third. FULL K02M 2018 RESULTS HERE.
Here’s Robert Brantley after his superb qualifying performance, which set a new 2018 King of 2 Miles qualifying round record. Going perfect on targets 1, 2, and 3, Robert missed just one shot on Target 4 of the qualifying phase, amassing 51355 points, a new K02M record.
CLICK HERE for a very complete and thorough KO2M report created by The Precision Rifle Blog (PRB). This excellent PRB Report contains complete load and rig specifications for the top five shooters. In addition, the PRB Report includes a full run-down on this year’s event.
Though the trigger pullers get the glory, this is really a three-man game. One guy shoots, a second team member spots for hits and calls corrections, and a third watches mirage and makes wind calls.
Multi-Day, Multi-Distance Competition with Farthest Target at 3525 Yards
The K02M Competition runs in stages, with the distances getting farther with each round. After five shots on target 1 at 1547 yards, there are then three shots per target for the remaining three parts of the Qualifying round. Then, in the three-target Finals phase, there are with five shots per target. You get more points for earlier hits in each string, and there are no sighters during the match. The event started with a tough Cold Bore Challenge — a single-shot at 1689 yards, just shy of one mile. Only three out of 62 competitors made that cold-bore mile shot on a 16″ plate, about 1 MOA at that distance. After that there are two rounds with the targets arrayed as follows.
KO2M Qualification Round
1,547 yards: 5 shots, 24” x 37” rectangle
1,719 yards: 3 shots, 24” x 37” rectangle
1,890 yards: 3 shots, 30” x 37” rectangle
2,095 yards: 3 shots, 30” x 37” rectangle
KO2M Finals Round — July 4
2,727 yards: 5 shots, 33” x 41” rectangle
3,166 yards: 5 shots, 42” x 54” rectangle
3,525 yards: 5 shots, 48” x 60” rectangle
Big Bore Rifles with High-BC Bullets
This year saw the continued evolution of equipment. Top shooter Brantley shot a .416 Barrett with 500gr Cutting Edge bullets. Robert’s massive 44-lb rifle featured a 39″ K&P barrel, McMillan action, and a Manners LRT (Long Range Tactical) stock designed expressly for this KO2M competition.
Second Place John Buhay shot an improved version of the .375 CheyTac, with 353gr Lehigh Defense Match Solid bullets. Buhay’s 37.6-lb rig bosted a BAT action and 36″ Krieger barrel along with a fairly conventional McMillan MBR 1K benchrest stock. Mark King built the rifle.
Third Place Paul Phillips campaigned a .416 Barrett with 550gr Cutting Edge Lazer bullets. Paul’s 42-lb rig featured a BAT action and McMillan Beast 1 stock. Shown below is the latest rifle of 2017 K02M champ Derek Rodgers, a .416 Barrett also in a McMillan Beast. Derek spotted for Phillips in the match.
Optics Options
There was quite a variety of scopes used by Top K02M competitors, evidence that a number of manufacturers now offer optics with abundant elevation and the ability to stand up to heavy recoil. Here are the optics choices for the Top Five Shooters:
1. Bushnell XRS II 4.5-30x50mm with G3 reticle in Badger UniMount
2. Nightforce ATACR 5-25x56mm with MOAR reticle, with ERA-TAC Inclined Mount
3. Nightforce ATACR 5-25×56mm, with Charlie TARAC external Prism System for Elevation
4. Leupold Mark 5HD 5-25×56mm, in Spuhr mount with Charlie TARAC
5. Burris XTR II 5-25x50mm in Barrett rings
Notably, two of the top five used the Charlie TARAC prism system. This provides a ton of extra elevation by essentially shifting the view seen through the scope. The unit fits to the scope’s front objective.
GunsAmerica just released a detailed review of the recently-upgraded Kestrel 5700 Elite with LiNK, a software-enabled weather meter. If you compete in practical/tactical events (with targets at multiple distances), or campaign a wide selection of rifles, or shoot at Extreme Long Range, you may want to get this device. It offers unrivaled capabilities in a small package. This impressive handheld device combines weather-monitoring capabilities with a full-featured, very sophisticated ballistics solver that now calculates out to 5,500 yards. Using Bluetooth and LiNK technology it communicates with your mobile device as well as LiNK-enabled laser rangefinders.
Why You May Want to Buy the Kestrel 5700 Elite with LiNK:
— The Device can hold up to 30 different rifle/cartridge profiles, each with its own BC and muzzle velocity for ballistic calculations.
— The Device registers current windspeed, wind direction, air temp and pressure, and other variables, and then sends that info via Bluetooth to your smart-phone, updating the ballistic solution. It essentially updates your drop chart in real time.
— The Device “talks” to your smart-phone, providing a large, convenient display that can show both elevation clicks and wind corrections. The display essentially replaces your data card. The Smartphone integration also makes it easy to modify your different rifle/ammo profiles.
— The Device gives you come-ups and wind corrections for multiple targets (at various ranges). These can be displayed in a list, ordered by distance. This is a great feature, check it out:
Quick and Accurate Solutions for all Cartridge Types — Big and Small
The Kestrel 5700 Elite can work for everything from a .22 LR to a .50 BMG. In fact, GunsAmerica’s tester used the Kestrel 5700 for a 6.5 Creedmoor shooting out to 1070 yards, and then used the solver for a .22 LR match out to 300 yards. The data for the 6.5 CM was spot on, but even more remarkably, the holdover for the .22 LR was precise to 0.2 mils at 300 yards. The GunsAmerica Reviewer, Ian Kenney, was impressed:
“I think the best testament to the capabilities of the Kestrel 5700 Elite were on display at a recent range trip where I was getting my modified Ruger 10/22 ready for an upcoming precision rimfire match. I started out with a sort of hodgepodge of information, using an unconfirmed BC [for Eley Force ammo] that I’d heard from a friend along with a muzzle velocity that another friend had gotten with the same ammo. I created a new profile using this assortment of data and entered in target distances for 200 and 300 yards. Imagine the smile on my face then when I got hits at both distances with the elevation setting only being 0.2 mils off at the farthest target.
It’s impressive that the technology allowed me to only be 0.2 mils off with .22 LR ammunition at 300 yards, which is only about two inches, all the while starting out with imperfect data. If that’s not an exquisite demonstration of the versatility of this technology, to be able to toggle between such diverse calibers and get accurate data to long distances, I don’t know what is.”
Kestrel 5700 Elite Special Capabilities
The LiNK Ballistics App lets you set up multiple targets for single-screen viewing. The Kestrel 5700 Elite can also be wirelessly paired with LiNK-compatible laser rangefinders. Being able to instantly accees exact target range data allows a more rapid and and more precise ballistic solution.
In addition to the ballistics solver capabilities, the Kestrel 5700 Elite is a comprehensive weather meter that monitors all key variables including: wind speed and direction, temperature, humidity, heat index, pressure, and altitude. Your data log can be transferred to a iOS/Android device wirelessly with the LiNK wireless communication option and Kestrel LiNK app. The 5700 Elite now uses a single AA Battery housed separately from the circuit board.
More Features of the Kestrel 5700 Elite
The Kestrel 5700 elite has almost too many features to list. One notable capability allows you to quickly “tune” a profile by entering field-confirmed data. Kenney explains: “You can go into the gun profile and calibrate the muzzle velocity by telling it how much elevation you used to get a hit, effectively truing your dope in short order. This is ten times faster than logging it in your data book, going back to an online solver, and making adjustments[.]”
Ian Kenney’s Kestrel 5700 Elite Review is very thorough, and contains many more details and insights than we can cover here. For anyone considering purchase of a high-end Kestrel, we strongly recommend you read Kenney’s review. Ian concludes: “I’m not going to lie… with an MSRP of $699, I recognize [the Kestrel 5700 Elite] may not be for everyone. Considering how often I shoot long range and the number of rifles that I have, it makes sense for me[.] The Applied Ballistics solver also gives me the confidence that my dope is going to be accurate no matter what conditions I might find myself in. So for me… this Kestrel delivers the goods.”

Want to learn more about Long Range Shooting? Check out the “Elements of Long Range Shooting” videos from the National Shooting Sport Foundation (NSSF). In this multi-part series, Bryan Litz of Applied Ballistics covers a variety of topics of interest to precision shooters. Today we feature three of these videos. There are five other videos in this series. Watch the entire 8-video “Elements of Long Range Shooting” series on the NSSF YouTube Channel.
Atmospherics and Density Altitude
Bryan Litz explains: “An important element in calculating an accurate firing solution for long-range shooting is understanding the effects of atmospherics on a projectile.” Atmospherics include air pressure, air temperature, and humidity. Bryan notes: “Temperature, pressure, and humidity all affect the air density… that the bullet is flying through. You can combine all those factors into one variable called ‘Density Altitude’.” Density Altitude is used by the ballistic solver to account for air density variables that affect bullet flight.
Bullet Ballistic Coefficients
A bullet’s ballistic coefficient (BC) basically expresses how well the bullet flies through the air. Higher BC bullets have less aerodynamic drag than lower BC projectiles. You will see BCs listed as either G1 and G7 numbers. These correspond to different bullet shape models. Generally speaking, the G7 model works better for the long, boat-tail bullets used for long-range shooting. Notably, a bullet’s drag is NOT constant in flight. The true BC can vary over the course of the trajectory as the bullet velocity degrades. In other words, “BC is dynamic”. That said, you can make very accurate drop charts using the BCs provided by major bullet-makers, as plugged into solvers. However, long-range competitors may want to record “real world” drop numbers at various distances. For example, we’ve seen trajectories be higher than predicted at 500 yards, yet lower than predicted at 1000.
Ballistics Solvers — Many Options
Bryan Litz observes: “When we talk about the elements of long range shooting, obviously a very important element is a getting a fire solution, using a ballistic solver. There are a lot of ballistic solvers out there… Applied Ballistics has smartphone Apps. Applied Ballistics has integrated the ballistic solver directly into a Kestral, and the same solver runs (manually) on the Accuracy Solutions Wiz-Wheel. The point is, if it is an Applied Ballistics device it is running the same solutions across the board.”
About Bryan Litz
Bryan began his career as a rocket scientist, quite literally. He then started Applied Ballistics, the leading company focusing on ballistics science for rifle shooting. A past F-TR Long-Range National Champion and Chief Ballistician for Berger Bullets, knows his stuff. His Applied Ballistics squad was the winning team at the 2017 King of 2 Miles event, and Applied Ballistics recently received a major U.S. defense contract to to execute Phase 1 of the Extreme Sniper Strike Operations (ESSO) project.
SIG Sauer and Applied Ballistics showed off impressive new electro-optical technology at the NRA Show in Dallas. Bryan Litz says “SIG Sauer’s Ballistics Data Exchange (BDX) is game changer. Imagine lazing a long range target, and having your exact fire solution (hold-over) automatically projected into your scope based on your ballistic profile.”
BDX takes target range info from a SIG Sauer Laser Rangefinder, calculates a ballistic solution using Applied Ballistics software, then displays the hold-over info directly in the optic (via a wireless BlueTooth connection). Just dial and shoot. Put the calculated BDX dot on the target and shoot. This ground-breaking BDX technology enables key ballistic hold-over information to be exchanged wirelessly among BDX-enabled Electro-Optics products.
You can buy this as a package with scope and LRF, starting at just $700.00 for scope and rangefinder. To our surprise, these scopes have a normal form factor. They look completely “normal”, with no clunky receiver boxes or extra turrets. BDX riflescopes aren’t bulky or heavy even though they include built-in electronics, level, and inclination detection.
“Rangefinding riflescopes of the past have had two major shortcomings: they are either big, boxy and heavy, or extremely expensive. The … BDX system packs advanced ballistics technology into a simple platform that looks just like the rangefinder and riflescope [hunters use] today. It is extremely simple to use. Range a target, put the digital ballistic holdover dot on target, pull the trigger — just connect the dot.” — Andy York, President, SIG Sauer Electro-Optics.
SIG Sauer’s Ballistics Data Exchange (BDX) is an integrated system of devices that talk seamlessly to each other, sharing data. Applied Ballistics says this system be expanded in the months ahead. “This system will be comprised of scopes, rangefinders, binoculars, and more. BDX will even be able to ‘talk’ to Kestrels and Garmins as well as SIG Sauer smart-scopes. This is only the start, over the next year you will see increasing levels of tech becoming available.”
How BDX (Ballistics Data Exchange) Functions — Software and Hardware
How does BDX work? First download the SIG BDX App for Android or iOS. Then pair the KILO BDX rangefinder and SIERRA3BDX riflescope, and set up a basic ballistic profile. Once you are in the field, range your target as you normally would, and the KILO BDX rangefinder will utilize onboard Applied Ballistics Ultralight™ to instantly send your dope to the scope via Bluetooth. Using your basic ballistic profile, the ballistic solution is calculated for your target and will instantly illuminate on the BDX-R1 Digital Ballistic Reticle with windage and elevation holds in the SIERRA3BDX riflescope. A blue LED on the riflescope power selector indicates that the BDX system is paired, and when the reticle has received new ballistic holdover and windage data from the rangefinder.
Story based on report by Paul Phillips of Global Precision Group
Extreme Long Range (ELR) shooting continues to evolve, with new forms of competition “pushing the envelope” of marksmanship (and ballistics) at distances out to 4900 yards (2.8 miles) and beyond. The latest big-time ELR shooting match was the World’s Longest Shot Challenge (WLSC) in Texas. This match was held at the Valdina Ranch, 1700+ acres of gorgeous hill country property, located about 1.5 hours west of San Antonio, Texas. The event attracted 28 shooters competing in four classes. Each competitor could be supported by a spotter and a wind coach, shooting as a three-person team.
Key “Take-Aways” from the 2018 WLSC Match:
1. Prototype Berger .375 Caliber Bullet is a Winner
The new .375 caliber monolithic Berger bullet designed by Bryan Litz was used by the first and second place finisher in the above .338 Caliber class. It performed great and the ultra-high BC was confirmed.
2. Team Applied Ballistics Dominated
The combined Applied Ballistics Team made first-round impacts at 1760, 2000, 2200, and 2400 yards. Also, 11 out of the 12 impacts total at 2200 yards belonged to Team AB. And Team AB’s Chris Palka had the top score overall, in his first-ever major ELR competition. That demonstrates how well the AB ballistics solutions work. By yardage, Chris recorded 68280 points total, as follows: 1760×6, 2000×10, 2200×9, 2400×3, 2680×4.
Christopher Palka (Team AB), shooting his first-ever ELR match, finished First Overall. Tactiholics Photo.
3. Got Doppler? Advanced Radar Technology for ELR
To shoot at these extreme ranges, you need rock-solid BC information on your projectiles. Luckily Applied Ballistics brought a Doppler Radar and allowed competitors to shoot their ammo to give them personalized ballistic information.
Top Shots By Class
Above .338 Non-Factory (mostly .375 CheyTac)
.338 and under Factory (mostly .338 Lapua Mag)
.338 and under Non-Factory (mostly .338 Edge)
Chris Palka 68280 HIGH SCORE
Paul Phillips 57360
Chase Stroud 47520
Pete Contacos 44360
Paul Phillips 20080
Chris Wiencke 14160
Tim Seller 25760
Eddie 14560
Calvin 11200
NOTE: There was also a fourth class at the WLSC, the “Above .338 Factory Class” (.50 BMG) with Jay Divorsky scoring 14560.
WLSC Match Procedures and Scoring:
Competitors shot with time limits at each distance: 5 minutes to make 5 shots at each plate. Hits on steel scored points, with a big premium on first-round hits. The point values (for hits) were based upon standard ELR practice: 5 times the distance on the first shot, 4 times the distance on the second shot, and so on. In this ELR match each team may have three members: Shooter, Wind Coach, and Spotter.
Paul Phillips reported: “After drawing names randomly for shooting order, on Day One we shot 36″ metal plates at 1760, 2000, 2200, and 2400 yards. The second day was elimination day — you had to make impact on each target at least once to advance to the next distance. These targets started at 2680 ranging out to 4900 yards. We had winds from 4-8 mph on the first day and 6-15 mph on the second day which made it very challenging.”
Proof in the Shooting — AB Solvers and Berger Bullets
Bryan Litz of Applied Ballistics stated: “This event was a successful test of several new things. Berger’s prototype .375 caliber solid bullets worked well in numerous guns and tracked perfectly to the most distant targets. Radar measurements of these new bullets indicate extraordinary performance as well. The AB Team also had a couple new staff members shooting their first ELR competition (Chris Palka and Chris Wiencke) who both did well with Chris Palka actually winning the event. This match was a successful demonstration of the science of accuracy being used to put rounds on target. The thing about science, is that it works the same for everyone. The ballistic software and Custom Drag Model (CDM) data that we used to put first-round hits on targets out to 2400 yards is the same software that’s available to everyone in the AB devices (Kestrel, Sig Kilo, Garmin Fortrex) and Mobile Apps.”
The AB ELR Team dominated the Podium in the above .338 Non-Factory Class. Chris Palka was high scorer followed by Paul Phillips (Second) and Chase Stroud (Third). The top two finishers were using Applied Ballistic Weapon Division Rifles sending the new Berger .375-Cal solid bullets designed by Bryan Litz. The third place finisher shot a .375 CheyTac with 400 grain Cutting Edge Laser bullets.
In the .338 and under Factory Class there were mostly .338 Lapua Magnums. These .338s did very well and two out of the three shooters made it to the two-mile plate. The final standings in the 338 and under Factory Class: Peter Contacos (first), Paul Phillips (second), Chris Wiencke (Third). Both Paul and Chris were shooting 300 grain Berger bullets.
Title Sponsor ELRHQ, a McMillan company, brought tables full of gear. Everything was on display: scopes, bipods, mats, bags, triggers, actions, brakes, stocks, LabRadars, TargetVision target cams, and more. ELRHQ.com is a great one-stop online vendor with the latest and greatest gear for those interested in the ELR discipline and precision shooting.
The match was organized by Travis Walla who did a great job. The event ran smoothly and shooters say the Texas BBQ was great. Travis posted: “We had an awesome event, thanks to all of our sponsors that helped make this event a huge success. We also had a awesome opportunity for those that shot this match — they were able to shoot across the Oehler Research 88 and Applied Ballistics LLC radar at the same time out to 2400 yards on Saturday afternoon. Thanks again…”
We want to congratulate Bryan Litz and his talented team at Applied Ballistics LLC. We have followed Bryan’s career as a bullet designer, ballistician, author, software product developer, and ELR pioneer. His team leads the world in advancing the science of long range shooting. And it looks like all the hard work has paid off — Applied Ballistics has secured a major contract to develop extreme long-range sniper capability for the U.S. Military.
Applied Ballistics LLC, a Michigan-based tech company, has been awarded a $1,300,000 contract by the Combating Terrorism Technical Support Office (CTTSO) to execute Phase 1 of the Extreme Sniper Strike Operations (ESSO) project.
Phase 1 of the ESSO project is focused on advancing the predictive capabilities of modern ballistic solvers by performing Doppler radar measurement and modeling of current service rounds at Extreme Long Range (ELR) as a function of gyroscopic stability, and refining the models of secondary ballistic effects such as spin rate decay and spin drift at ELR. Phase 1 will conclude with the ballistic modeling enhancements being integrated into the existing Applied Ballistics ecosystem of electronic devices which are currently deployed by numerous U.S. and allied armed forces around the world. Phase 1 is scheduled for completion in late 2018.
Phase 2 of the ESSO project is a potential follow on (2019) that focuses on the development and fielding of an advanced ELR sniper rifle system designed to drastically increase first-round hit probability at ELR on man-sized targets. The Applied Ballistics Weapons Division is currently conducting research and development on weapons platforms, as well as new cartridge and bullet options, that will maximize ELR ballistic performance from lightweight, practical, magazine-fed systems.
Bryan Litz, owner of Applied Ballistics LLC, said: “Our team of Aerospace, Mechanical, Electrical and Computer Science Engineers, and Technicians will apply our combined experience including years of testing and competing in ELR Shooting to the successful completion of the ESSO program objectives. This means extending the maximum effective range of U.S. and allied snipers, achieving decisive overmatch on the battlefield. I can’t imagine a better application of Applied Ballistics’ collective efforts.”
Applied Ballistics has developed ballistics software for mobile Apps. AB’s software has been integrated into numerous products including Kestrels, Laser Rangefinders, and “Smart” optics.

Part 2 of this Volume is focused on various aspects of advanced hand-loading. Modern Advancements (Vol. II) employs live fire testing to answer the important questions that precision hand loaders are asking. What are the best ways to achieve MVs with low ES and SD? Do flash hole deburring, neck tension, primer selection, and fill ratio and powder scales sensitivity make a difference and how much? All of these questions are explored in detail with a clear explanation of test results.
