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.

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.

Bushnell has released a FREE new Ballistics App powered by the Applied Ballistics Ultralite Engine. The new Bushnell Ballistics App easily calculates ballistic solutions for any popular cartridge type once you input velocity, BC, and atmospherics. The App features trusty Applied Ballistics bullet data, and it can even pull in atmospheric data from web weather sources. This allows you to calculate hold-overs and make precise wind corrections. The App is offered in both iOS and Android OS versions.
“The new Bushnell Ballistics App is powered by the Applied Ballistics Ultralite engine, the most trusted ballistics data-cruncher in the industry,” said Bushnell Marketing Manager Matt Rice. “This App allows users to easily build and modify gun profiles and build range cards to calculate firing solutions based on their specific scope and ammunition choices. All of our Bushnell scopes and reticles have been pre-loaded [in the App].”
The Bushnell App features AB Connect, a live library of G1/G7 data, plus the Applied Ballistics Bullet Library with 740+ pre-loaded bullet profiles. The Bushnell scope library features 150+ scopes and 30 reticle options. Atmospheric data can be updated manually or directly from the internet (when connected). Angle range compensation is also calculated. Gun profile management provides up to five saved profiles with reticle-based firing solutions. A multiple target feature saves up to five targets. Range cards can be shared or printed using the Email Range Card Function.
The FREE App works on both Android and iOS operating systems, and is available on Google Play and the App Store. It is optimized for Bushnell riflescopes and reticles, but is compatible with all optics. Once downloaded, the App functions off the grid — no cell service required.
“The new Bushnell Ballistic App puts the power of long-range, first-shot accuracy into the hands of any shooter,” Rice said. “it was designed to perform in any condition and to offer our consumers true value, with features that far exceed the price — which, in this case, is free!”
On 1/21/18, new World Records were set under ELR Central rules for verified, consecutive three-shot string without sighters. Competitors started from cold bore, no sighters or ranging shots allowed. That’s a tough standard. In fact the first 12 shooters failed to put three shots on target at 1500 yards before Paul Phillips took his turn. Paul, Lucky number 13, placed all three of his shots on the 36″ x 36″ plate, claiming a first-ever record. Later that afternoon, John Armstrong duplicated that feat, also putting three shots on target at 1500 with no sighters.
But the best performances of all came later. Nate Stallter, shooting a .375 CheyTac, nailed his three shots at over one mile — 1768 yards. But it gets better — Nate broke his own record later in the afternoon, going 3 for 3 at 2011 yards.
David Tubb posted: “Congratulations to my son-in-law, Nate. Today he won the ELR Central World Record competition. This competition allows two separate attempts (spaced four hours apart) and consists of three cold bore shots each time. He took 3 shots and had 3 hits at 1768 yards in the morning and then beat his own record in the afternoon with 3 shots and 3 hits at 2011 yards after the wind had become trickier.”
Stallter used the new Tubb Adaptive Target Rifle (Tubb Gun) with a Dynamic Targeting Reticle and Tubb T7T two-stage trigger. He was shooting the .375 Cheytac with a 364gr Warner flatline bullet that has a patent pending Nose Ring modification in a Schneider 1:7″ twist barrel. Three of the Tubb Rifles are shown below. Note the long barrels.
As we explained, this was a tough challenge. Competitors started with a cold bore, with no sighters alowed — that makes it especially tough.
Watch this video to hear the record-setting shooters describe their equipment — chambering, action, stock, barrel, bipod, and optics. No the video is not sideways! Nearly all this video is correct, horizontal orientation. Click triangle to start correct format.
None of the competitors had shot these kind of distances at this facility, the Front Sight Firearms Training Center in Pahrump, Nevada. And the “no sighters” rule really added to the difficulty — witness the fact that the first 12 shooters failed to put three consecutive hits on a square yard of steel at 1500. Here are the three record-setting shooters:
1. Paul Phillips, 1500 yards (first record) | 2. John Armstrong, 1500 yards (tied record)
Those who understand the challenge were impressed …
Andy McNeill observed: “I’ve shot targets further too, but I didn’t go 3 for 3 with no sighters. These hit cold bore and then two consecutive follow-up shots at specific target sizes. This is what a record should be. Not I hit a target at X distance once after slinging lead at it all day.”
Jacob Scobell liked the match format: “Love that this is intentional, consecutive impacts with a fixed size target and not just a statistical probability of hitting the broad side of a barn with unlimited shots. Excellent to see a standard being set.
Now will all of these other supposed ‘world record holders’ step up and enter this competition? Sure some guy who can impact upon demand beyond 4000 yards would cake walk this right? A registered event with multiple shooters means put up or shut up.”
The latest issue of Shooting USA magazine has a detailed EIGHT-page feature on the Kestrel wind meter. This story covers the development of the Kestrel and explains the advanced technologies now offered with the hand-held Kestrel systems.
The eZine version of Shooting Sports USA (SSUSA) is available for free online. In the latest December 2017 issue you’ll find two excellent articles of interest to all serious rifle shooters. One covers the development of the Kestrel weather meter, which has evolved to serious levels of sophistication. Now premium Kestrels include built-in ballistic calculators and they can “talk” with mobile devices, sharing command functions and data. The second article covers shooting skills. In the first of a three-part series, Glen Zediker talks about NRA High Power rifle competition. Glen spotlights the skills you must master to move from the beginning level, Marksman, to higher levels.
Kestrel Technology Today
The December SSUSA issue features the origin of ballistics-enabled Kestrel weather meters. SSUSA’s Editor John Parker covers the history of the Kestrel, and explains how more and more features were packed into the handheld device as it evolved. Today’s Kestrel is so much more than an impeller with wind speed/direction read-outs.
The impressive Kestrel 5700 Elite with Applied Ballistics software is the latest model of a product that revolutionized long-range shooting by combining ballistic computer and weather meter in one portable device. Shooters can select either G1 or G7 ballistic coefficients, or to be even more specific they can select bullets from the Applied Ballistics custom curves library. With the Kestrel and its software, shooters can plot very precise trajectories, even to extreme long ranges.
Marksman to High Master
High Power Rifle competition originally evolved from the U.S. military course of fire. Climbing the classification ranks in NRA High Power Rifle can be daunting — it requires focus, practice and commitment to move up the ladder from Marksman all the way to High Master.
In Glen Zediker’s three-part series, “Climbing the High Power Ladder”, Glen shares his tips for competitors that are looking to improve their skills beyond the intermediate level. The first installment focuses on stepping past Marksman classification to Sharpshooter. Read PART ONE HERE. In the months ahead, look for parts Two and Three in future SSUSA issues. These will cover the next stages in the climb: Expert, Master, High Master.
DVD Resource for High Power Training
If you’re serious about improving your High Power skill set, we suggest you view a DVD by David Tubb, 11-time National High Power Champion. David’s instructional DVD, “The Art & Technique of the Modern Match Rifle”, is a great resource for any High Power or position shooter. This 2-disc DVD provides over 4.5 hours of instruction and shooting demonstrations. We can confirm that this video is packed with great information — novice High Power and prone shooters who apply David’s methods should definitely improve their scores.
David has included highlights from that DVD in a shorter promo video. While the shorter video is a sales tool, it’s very informative in its own right. Watch the video and you’ll learn a great deal just by watching how David shoulders his rifle, and how he adjusts and maintains his shooting position. David shows examples of prone, sitting, and standing positions. In the short “trailer”, David also provides helpful tips on adjusting sights, and placing the spotting scope.
If you shoot Service Rifle, High Power, or prone, you can benefit from watching this short sampler video. The full 2-disc DVD is available for $49.95 from Creedmoor Sports. With over 4.5 hours of content, the DVD covers all the across-the-course positions, the set-up and use of aperture sights and diopters, High Power and long range targets, the approach method in offhand, proper placement and use of spotting scopes. The DVD includes bonus footage of David shooting strings in all of the across-the-course positions.
First there were books, then Videos/DVDs, then Ballistic Apps, then Seminars, and now Applied Ballistics is moving into the gun-building business. Founded by Ballistics guru Bryan Litz, Applied Ballistics LLC has been a world leader in the science of ballistics for the shooting sports. Now Applied Ballistics is using its expertise to produce complete rifle systems capable of world-beating Extreme Long Range performance.
Applied Ballistics Weapons Division Will Offer Complete Tactical ELR System
Applied Ballistics Weapons Division (ABWD) states: “We have the capability to build you a custom rifle, with ammo matched for that system. We can test the ammo and rifle combination over Radar in the lab. ABWD [will be] offering a complete system, with a CDM specific to that rifle. The first rifles are purpose built for 2500+ yard engagements.”
Based on the “teaser” video above, ABWD will offer a complete rifle system featuring Nightforce riflescope, ELR optical prism, laser rangefinder, Kestrel wind meter, and ammo that has been tuned for the rifle and trajectory-verified with Doppler Radar. This promises a “turn-key” system with sub-MOA 1000-yard accuracy plus hit capability at ranges out to 2500+ yards.
One Facebook reader asked: “Will you focus your rifle builds to just Extreme Long Range or will you be doing PRS-style type rifles as well?
AB states: “We are starting out with this ELR system, but will be offering more systems in the near future, as well as custom rifle builds. Stay tuned as the ABWD website should be up soon!”
Many Questions about ABWD’s New Products:
Of course, like our readers, we have many questions about this new project:
1. What cartridge types will be available in ABWD Rifles?
2. What companies will supply the rifle actions and chassis systems?
3. Who will supply the barrels and what are length/chambering options?
4. Will ABWD rifle systems be offered to the general public (vs. military/LEO)?
5. When will the first ABWD rifle systems be available?
And last but not least…
6. What will these ABWD ELR Rifles cost, both by themselves and as a complete package (with solvers, LRFs, optics etc.)?

2017 K02M Match-Winning Performance on Video
The video below shows Team Applied Ballistics shooter Derek Rodgers winning the 2017 King of 2 Miles event. This excellent video combines firing line and target-cam views. You can see the strings-of-fire at 2667 and 3028 yards. Then Watch Derek, after four misses, hit the last target with his fifth (and final) round! That plate was set at a mind-numbing 3368 yards (1.91 miles). Derek had Paul Phillips as a spotter and Emil Praslick as a wind coach — a very powerful team and it showed.
If you want to learn more about ELR shooting and how team Applied Ballistics achieves great results in ELR competition, we recommend an excellent article just released byShooting Sports USA. SSUSA’s Editor John Parker interviewed Team Applied Ballistics members Bryan Litz and Paul Phillips. Both men said that successful Extreme Long Range shooting requires solid team-work.
Bryan Litz (center) conferring with Team AB members Emil Praslick (L) and Doc Beech (R).
Paul Phillips explained: “ELR is very difficult. It requires a great shooter with 1/2-MOA accuracy, a really good wind coach and spotter to see impacts, trace and the ability to quickly negotiate and engage the targets. It’s one fluid team working together.”
Bryan Litz, Applied Ballistics founder, concurred: “Of all the various precision rifle disciplines, ELR shooting is particularly suited to a team approach. All aspects of ELR shooting are both highly challenging as well as critical to success. One individual is typically not able to stay on top of all the variables effectively enough to hit targets at extreme ranges all by themselves.”
Litz says superior wind-reading skills are vital in the ELR game: “One of the important challenges of hitting targets at long range is reading the wind. All the shooters on our team can read wind, but when we’re shooting a match, we put our strongest wind-reader in this position for all shooters. Emil Praslick is arguably the best in the world at putting a number on the wind. He’s got a well-rehearsed process that works in all scenarios. When Emil isn’t available, someone else on our team will apply his process and focus specifically on the wind.”

The Battle of Nations begins. Today is Day 1 of international team competition at the 2017 F-Class World Championships (FCWC) in Ottawa, ON, Canada. Talented teams, in their nation’s colors, will be competing for glory and national pride.
Team shooting is very different than individual competition. Typically a team coach makes the wind calls for the shooters. In some cases (where the rules allow), the wind coach even dials elevation and windage changes for the active shooter. For the wind coach to do his job effectively, he must follow the changes in the wind and determine what the correct wind call should have been for each shot. (In other words — what was the “right call”)
Past F-TR USA Nat’l Champ Bryan Litz was wind coach for the winning 4-man LUM F-TR Team at the 2017 Canadian F-Class Championships, which preceded the FCWC Worlds. Here Bryan explains how he uses a Wind Plot to make better wind calls, helping his team-mates maximize their scores.
Wind Plot Methodology by Bryan Litz
The wind plot I use is a running history of what the correct wind call was for every shot fired. The more you shoot, the more history you have in a condition, and I find that very useful information. This kind of plot IS NOT showing where the bullet hit, and is NOT showing what you held. It’s showing what you should have held to center each shot. IMO, this is the most valuable information to have when guessing where to hold next for each shot. Here are some key points:
1. I always look for blocks of stable conditions to shoot in and wait out the rest.
2. If the wind plot shows drastic changes, either I’m not picking the right time to shoot or it’s just a really unstable wind condition.
3. When you see many shots using the same hold (e.g. Robby’s 700m and 900m strings on plot), it can indicate very fast shooting and fast pit service.
Q. What are the numbers and Markings on this Wind Plot?
Litz: The wind plot represents the rings on the target. Left 2 for example, is the 5 line on the international target, while Left 2 is the 10 line on the USA target. F-Class shooters and coaches talk about wind holds in relation to these rings. A Left 2 hold isn’t left 2 MOA or 2 MILS, it’s the second ring from center. The vertical lines on the plot represent the rings going out from center, 4 or 5 in each direction. A left or right 5 hold is edge of black on the int’l target.
Q: What Does this Specific Plot Reveal?
Litz: Looking at the plot, from left to right is 700m, 800m, and 900m that we shot progressively through the day. Top to bottom shows each shooter in sequence (shooters names are shown by their blocks). To the right I note what was on the gun for that shooter, and note when it changes. Often times we run the same wind on the gun for several shooters but if it changes, I note what the new windage is and continue on. For example if we’re settled into a condition where we’re shooting Vs with a right 3 hold, I might adjust the scope 1 MOA right because a right 3 hold is equal to 1 MOA. So we can move the scope and start shooting with a center hold.
Q. Are you Plotting Where the Bullet Hits?
Litz: Not exactly. This kind of plot IS NOT specifically showing where the bullet hit, and IS NOT showing what the shooter held. It’s showing what the shooter should have held to center each shot. IMO, this is the most valuable information to have when guessing where to hold next for each shot.
On each shot, the shooter or coach takes a guess about where to hold, and fires the shot. If the bullet hits the center, you plot the point right where you held because it was the correct hold. However, if you miss the call, you plot what hold was required to put that shot in the center. For example if you shoot a right 3 and hit where you held, the correct call would have been “center”. In this way, you’re building a history of what you should have done, which may or may not be what you actually did. This shows you the trends, and brackets which can be used to make future decisions.
Q: Is this Type of Wind Plot Something New?
Litz: I didn’t invent this method, it’s been around a long time. Vertical can be plotted the same way. In team matches, we have a plotter who is advising on elevation trends and suggesting corrections. But, as wind coach, my job is the horizontal so I only keep the wind plot. I have learned lots of strategies from my coaches Emil Praslick and Steve Hardin.
There are many ways to plot and many standard work sheets for this. They’re all tools and the key is to find something that works for you in different situations. I don’t keep a plot when I am personally behind the trigger string firing because I lose more points when I take the time to do it vs. just shooting fast. When pair firing or coaching, I can keep the wind plot without compromising the shooting.
Team Australia used plots and comms linking coaches to help win the 2013 F-Open Team World Championship. We expect other teams will follow suit in Canada in 2017.
Know Your Goal — Keep It Simple
Know your goal of plotting. The simplest plot is where you write the shot number where it hit on a target face. This kind of plotting is useful for evaluating shooter performance because it shows how big the group is (in particular the vertical dispersion). However keeping a plot like this does little to help you figure out the wind. It just shows you what shots you messed up on. It does nothing to help you find the center. [Editor: That’s a whole different matter with many variables.] The wind plot I use is a running history of what the correct wind call was for every shot fired. The more you shoot, the more history you have in a condition, and I find that very useful information.
