When you’re on a varmint expedition in the Western states you can bet, sooner or later, you’ll encounter serious winds. Here’s some advice on how to minimize the effects of cross-winds on your shooting, and easily improve your percentage of hits. In essence, you want to use your ability to change shooting positions and angles to put the wind behind you.
A benchrest or High Power shooter must operate from a designated shooting position. He must stay put and deal with the wind as it moves across the course, from whatever direction it blows.
Put the Wind at Your Back
By contrast, a varmint hunter can move around and choose the spot that provides the most favorable wind direction. In most cases you’ll get the best results by moving your shooting position so the wind is at your back. This will minimize horizontal wind drift. Once you’re in position, use wind flags to direct your fire in line with the prevailing winds. A varminter who calls himself “Catshooter” explains:
The String of Death
I remember the first time I was on a dog town in the Conata Basin, in the Badlands area of southwestern South Dakota. Along with two other guys, I drove out for 21 days of shooting, and I never saw wind like that before. If all four tires of our vehicle were on the ground, the weather man said these were “mild wind conditions”.
After the first four or five days, we got smart. We would park the truck on the up-wind side of the town so the wind was at our back. Then we took a piece of string on a 3-foot stick, and set it in front of the shooters, and let the string point at the mounds that we were going to shoot.
For the rest of the trip, we didn’t have to deal with wind drift at all. We just shot the dogs that the string pointed to. We started calling our simple wind pointer the “String of Death”.
We were hitting dogs at distances that I would not repeat here (with benchrest grade rifles). After the first time out, I always took a wind rig like that.
Benefits of Swivel Benches
In a large varmint field, you’ll want to orient your shooting position to put the wind at your back if possible. If you have a rotating bench such as this, you can further adjust your shooting orientation to work with the wind, not against it. You may also want to position simple flags (posts with colored tape) downrange to alert you to wind changes you may not notice from your shooting positions. If you can’t get a “wind at back” orientation, the next best set-up is with the wind coming straight at you — that also minimizes the wind drift on your shots.
To succeed in long-range shooting matches, given the high level of competition these days, you’ll need solid wind-reading abilities. We’ve found an article by SFC Emil Praslick III, retired USAMU Service Rifle coach and U.S. Palma Team Coach, that can help you make better wind calls in competition.
Emil Praslick, now retired from the U.S. Army, is considered one of the best wind gurus in the United States, if not the world. During his service with the USAMU he authored an excellent two-part article on wind reading that is available on the CMP (Civilian Marksmanship Program) website. Both articles contain helpful illustrations, and are “must-read” resources for any long-range shooter–not just Service Rifle and Highpower competitors.
Part One covers basic principles, tactics, and strategies, with a focus on the 200-yard stages. Emil writes: “There are as many dimensions to ‘wind reading’ as there are stages to High Power competition. Your tactical mindset, or philosophy, must be different for the 200 and 300 yard rapid-fire stages than it would be for the 600 yard slow-fire. In the slow-fire stages you have the ability to adjust windage from shot to shot, utilizing the location of the previous shot as an indicator. Additionally, a change to the existing conditions can be identified and adjusted for prior to shooting the next shot.”
In Part Two, Praslick provides more detailed explanations of the key principles of wind zeros, wind reading, and the Clock System for determining wind values: “The Value of the wind is as important as its speed when deciding the proper windage to place on the rifle. A 10 MPH wind from ’12 o-clock’ has No Value, hence it will not effect the flight of the bullet. A 10 MPH wind from ‘3 o’clock’, however, would be classified as Full Value. Failure to correct for a Full Value wind will surely result in a less than desirable result.”
Praslick also explains how to identify and evaluate MIRAGE:
Determine the accuracy of the mirage. Mirage is the reflection of light through layers of air that have different temperatures than the ground. These layers are blown by the wind and can be monitored to detect wind direction and speed.
Focus your scope midway between yourself and the target, this will make mirage appear more prominent. I must emphasize the importance of experience when using mirage as a wind-reading tool. The best way to become proficient in the use of mirage is to correlate its appearance to a known condition. Using this as a baseline, changes in mirage can be equated to changes in the value of the wind. Above all, you must practice this skill!

Forest of Windflags at World Benchrest Championships in France in 2011
There’s a simple, inexpensive “miracle device” that can cut your groups in half. If you’re not using this device, you’re giving away accuracy. The “miracle device” to which we refer is a simple wind indicator aka “windflag”. Using windflags may actually improve your accuracy on target much more than weighing charges to the kernel, or spending your life savings on the “latest and greatest” hardware.
Remarkably, many shooters who spend $3000.00 or more on a precision rifle never bother to set up windflags, or even simple wood stakes with some ribbon to show the wind. Whether you’re a competitive shooter, a varminter, or someone who just likes to punch small groups, you should always take a set of windflags (or some kind of wind indicators) when you head to the range or the prairie dog fields. And yes, if you pay attention to your windflags, you can easily cut your group sizes in half. Here’s proof…
Miss a 5 mph Shift and You Could DOUBLE Your Group Size
The table below records the effect of a 5 mph crosswind at 100, 200, and 300 yards. You may be thinking, “well, I’d never miss a 5 mph let-off.” Consider this — if a gentle 2.5 mph breeze switches from 3 o’clock (R to L) to 9 o’clock (L to R), you’ve just missed a 5 mph net change. What will that do to your group? Look at the table to find out.
Values from Point Blank Ballistics software for 500′ elevation and 70° temperature.
Imagine you have a 6mm rifle that shoots half-MOA consistently in no-wind conditions. What happens if you miss a 5 mph shift (the equivalent of a full reversal of a 2.5 mph crosswind)? Well, if you’re shooting a 68gr flatbase bullet, your shot is going to move about 0.49″ at 100 yards, nearly doubling your group size. With a 105gr VLD, the bullet moves 0.28″ … not as much to be sure, but still enough to ruin a nice small group. What about an AR15, shooting 55-grainers at 3300 fps? Well, if you miss that same 5 mph shift, your low-BC bullet moves 0.68″. That pushes a half-inch group well past an inch. If you had a half-MOA capable AR, now it’s shooting worse than 1 MOA. And, as you might expect, the wind effects at 200 and 300 yards are even more dramatic. If you miss a 5 mph, full-value wind change, your 300-yard group could easily expand by 2.5″ or more.
If you’ve already invested in an accurate rifle with a good barrel, you are “throwing away” accuracy if you shoot without wind flags. You can spend a ton of money on fancy shooting accessories (such as expensive front rests and spotting scopes) but, dollar for dollar, nothing will potentially improve your shooting as much as a good set of windflags, used religiously.
Windflags Sources and Options
Which Windflag to buy? There are many vendors selling windflags of various types, some with daisy wheels others without. You may want to go to a match and see what types works best for you. CLICK HERE for the Benchrest Central Classifieds with multiple windflag types and accessories for sale. Here is a sample:
The 2022 NRA F-Class National Championships have been underway at the Ben Avery Range in Arizona this past week. The Mid-Range F-Class Nationals ran October 16-19, and the Long Range (1000-yard) event started on October 20 and concludes on Sunday, October 23, 2022. Many of the nation’s leading F-TR and F-Open shooters are battling it out at Ben Avery right now. The week of competition will conclude on Sunday October 23, 2022 with the final 1000-yard relays followed by award ceremonies.

F-Class Shooting at Bisley Range in the United Kingdom
F-Class competition is popular around the world, and the UK is a major center of F-Class shooting in Europe. The Bisley range is justly famous, with a long heritage of shooting competitions. This video features the European F-Class Championship held at Bisley in 2015.
Highlights from Day 1 of 2021 F-Class Nationals
In 2021 the NRA F-Class National Championships were held at Camp Atterbury, Indiana. Here is interesting footage from Day 1 of the Long-Range 1000-yard match. The video is narrated by our friend Erik Cortina, a top F-class shooter and member of Team Lapua-Brux-Borden. Erik has a popular YouTube Channel featuring interviews with many top shooters as well as reloading and tech tips.
WICKED WINDS — At Ben Avery with 18-30 mph Winds
Long-range F-Class shooters will tell you that the winds can be the biggest challenge in a match. And things can get pretty wild at times as the Ben Avery range in Phoenix, site of the 2022 NRA F-Class National Championships. In this video, shooters fight through extremely strong 18-30 mph winds at 600 yards. In these kind of extreme conditions, a major unexpected gust can send your bullet off-target.

Front Rest Options for F-Open (and Benchrest) Competition
If you are shopping for a front rest, definitely watch this comprehensive 42-minute video from start to finish. This is probably the most informative video about premium shooting rests available on YouTube. Top F-Class shooter and video-maker F-Class John covers a wide selection of front rests, with some observations about coaxial bipods as well. John covers the impressive new SEB NEO-X, the easy-to-transport SEB Mini-X, the excellent Rodzilla Rest, the innovative 21st Century Hybrid Rest, the sleek Italian Lenzi Rest. And at the end of the video John reviews the very affordable Caldwell Fire Control Rest ($204.99 on Amazon), explaining how it can be a decent choice for shooters on a limited budget.
Newbie Perspective — First Time Shooting F-Class
Just getting started in F-Class? Then you would appreciate this video, which covers the experience of an F-Class novice from Australia. The host of the video shot his first F-Class match at 600 yards with the Brisbane Mariners Rifle Club (BMRC) in Brisbane, Australia. He was using a Tikka T3 factory rifle with a $40 bipod. He enjoyed the challenge and had a good experience. This video shows that club-level F-Class can be fun, even with a modestly-priced factory rig. NOTE: This video is filmed indoors after the match, NOT on the lovely BMRC range shown above.
Reloading for F-Class — Interview with Erik Cortina
In this Precision Rifle Network video, Erik Cortina of Team Lapua-Brux-Borden covers the reloading process for his F-Class rifle. All phases of reloading are noted — brass prep, annealing, primer seating, precision powder measuring (to the kernel), and bullet seating. Erik also talk about load testing and use of barrel tuners. Erik produces the EC Barrel Tuner which is used by many top competitors.
Building a Modern F-Open Stock for Competition
In this video, our friend F-Class John explains the process for building two custom laminated stocks for his F-Open rifles. John selected handsome, highly-figured African hardwoods, which were then laminated into layers with purple-tinted heart-wood and dark Wenge wood stringers in the middle. The stock-maker then sliced the wood into layers (1:02) and then glued the layers together (1:40). After final cutting, the stocks are shown at 2:00, and then the video shows how the stocks received their final finish. Both stocks are fitted with the R.A.D. recoil-reduction system. See the bedding at 19:00 and the fully finished rifles at 19:12 with barreled actions fitted.
Here is another beautiful F-Open stock, on the firing line at Ben Avery with a SEB Mini front rest. Note the metal side-bars on the front of the forearm. These metal fittings extend the stock’s “wheelbase” while also lowering the rifle’s center of gravity.
BONUS Video
Crazy Small F-Class Group — Five Shots in 1.3″ at 1000 Yards
This video might just make you slap your forehead and say “that’s amazing!” During a practice session, Erik Cortina had a camera set up on the firing line along with a ShotMarker system on the target 1000 yards away. Erik recorded himself nailing a 1.3″ five-shot group, with four of the shots all touching in just 0.3″. The full group size, 1.3″, works out to 0.124 MOA — amazing accuracy for a big 7mm cartridge! And the four touching shots in 0.3″ represent an insane 0.029 MOA cluster! (1 MOA at 1000 yards is 10.47″.) As this was not shot in a competition, Erik’s 1.3″ group doesn’t count as a record, but it just shows how accurate a modern F-Open rifle can be when all the stars align for a talented trigger-puller.

“The pessimist complains about the wind; the optimist expects it to change; the realist adjusts the sails.” — William Arthur Ward
Readers often ask us: “Is there a decent, easy-to-comprehend book that can help my wind-reading?” Many of our Forum members have recommended The Wind Book for Rifle Shooters by Linda Miller and Keith Cunningham.
New Edition Released in May 2020
A NEW hardback edition of The Wind Book was released May 26, 2020. This 144-page book, first published in 2007, is a great resource. But you don’t have to take our word for it. If you click this link, you can read book excerpts and decide for yourself. When the Amazon page opens, click the book cover (labeled “Look Inside”) and another screen will appear. This lets you preview the first few chapters, and see some illustrations. Along with the new hardback edition ($22.99), Amazon offers a Kindle (eBook) edition for $14.99.
Other books cover wind reading in a broader discussion of ballistics or long-range shooting, such as Applied Ballistics for Long-Range Shooting by Bryan Litz. But the Miller & Cunningham book is ALL about wind reading from cover to cover, and that is its strength. The book focuses on real world skills that can help you accurately gauge wind angle, wind velocity, and wind cycles.
All other factors being equal, it is your ability to read the wind that will make the most difference in your shooting accuracy. The better you understand the behavior of the wind, the better you will understand the behavior of your bullet. — Wind Book for Rifle Shooters
The Wind Book for Rifle Shooters covers techniques and tactics used by expert wind-readers. There are numerous charts and illustrations. The authors show you how to put together a simple wind-reading “toolbox” for calculating wind speed, direction, deflection and drift. Then they explain how to use these tools to read flags and mirage, record and interpret your observations, and time your shots to compensate for wind. Here are two reviews from actual book buyers:
I believe this is a must-have book if you are a long-range sport shooter. I compete in F-Class Open and when I first purchased this book and read it from cover to cover, it helped me understand wind reading and making accurate scope corrections. Buy this book, read it, put into practice what it tells you, you will not be disappointed. — P. Janzso
If you have one book for wind reading, this should be it. Whether you’re a novice or experienced wind shooter this book has something for you. It covers how to get wind speed and direction from flags, mirage, and natural phenomenon. In my opinion this is the best book for learning to read wind speed and direction. — Muddler

The channel’s creator, Thomas Haugland, is a serious, knowledgeable shooter, who takes his rifles out into the field, in all conditions. The THLR.NO channel offers solid advice on scopes, reticles, wind-reading, field positions, and much more. Haugland’s team puts a wide variety of gear through serious field tests — every thing from suppressors to packs to the latest electro-optical hardware. In addition the THLR.NO channel provides good advice on stalking techniques and hunting skills. Here are some recent videos that can help any rifleman.
How to Shoot Better with a Hunting Rifle
This “must-watch” video has great practical advice for hunters. It illustrates proper hand-hold and head position, and shows how to stay steady when breaking the shot. Even competition shooters can learn a few things. One viewer notes: “This was very informative. The footage through the scope showing how one’s position moves the sight alignment was particularly helpful.”
How to Gauge Wind Speed and Hold Off Using Reticles
This field video shows how to observe natural indicators — trees and vegetation — to estimate wind velocity. Then it shows how to calculate hold-offs using the reticle hash-marks. Thomas shoots a fast-cycling Blaser R93 rifle with Norma 6XC ammunition.
