Long Range Shooting on a Spinning Planet — The Coriolis Effect

Whittington Coriolis Effect
Photo by Dustin Ellermann at Whittington Center Range.

The Coriolis Effect comes into play with extreme long-range shots like this (2100 yards at Raton, New Mexico). The rotation of the earth actually moves the target a small distance (in space) during the long duration of the bullet’s flight.

Coriolis Effect Bryan Litz Applied BallisticsWhen you’re out at the range, the Earth seems very stable. But it is actually a big sphere zooming through space while spinning around its axis, one complete turn every 24 hours. The rotation of the earth can create problems for extreme long-range shooters. During extended bullet flight times, the rotation of the planet causes an apparent deflection of the bullet path over very long distances. This is the ballistics manifestation of the Coriolis Effect.

Bryan Litz of Applied Ballistics discusses explains the Coriolis Effect in his Ballistics Books and Seminars. Bryan notes that Coriolis is “a very subtle effect. People like to make more of it than it is because it seems mysterious.” In most common shooting situations inside 1K, Coriolis is not important. At 1000 yards, the Effect represents less than one click (for most cartridge types). Even well past 1000 yards, in windy conditions, the Coriolis Effect may well be “lost in the noise”. But in very calm conditions, when shooting at extreme ranges, Bryan says you can benefit from adjusting your ballistics solution for Coriolis.

Bryan explains: “The Coriolis Effect… has to do with the spin of the earth. You are basically shooting from one point to another on a rotating sphere, in an inertial reference frame. The consequence of that is that, if the flight time of the bullet gets significantly long, the bullet can have an apparent drift from its intended target. The amount [of apparent drift] is very small — it depends on your latitude and azimuth of fire on the planet.”

Coriolis Effect Bryan Litz Applied Ballistics

Coriolis is a very subtle effect. With typical bullet BCs and velocities, you must get to at least 1000 yards before Coriolis amounts to even one click. Accordingly, Bryan advises: “Coriolis Effect is NOT something to think about on moving targets, it is NOT something to think about in high, uncertain wind environments because there are variables that are dominating your uncertainty picture, and the Coriolis will distract you more than the correction is worth.”

“Where you could think about Coriolis, and have it be a major impact on your hit percentage, is if you are shooting at extended range, at relatively small targets, in low-wind conditions. Where you know your muzzle velocity and BC very well, [and there are] pristine conditions, that’s where you’re going to see Coriolis creep in. You’ll receive more refinement and accuracy in your ballistics solutions if you account for Coriolis on those types of shots. But in most practical long-range shooting situations, Coriolis is NOT important. What IS important is to understand is when you should think about it and when you shouldn’t, i.e. when applying it will matter and when it won’t.”

Optimize Your Aiming — Tips for F-Class Shooters

F-Class Aiming Long Range Score Shooting
The movie “The Patriot” gave us the phrase “Aim small, miss small”. While that’s a good mantra, aiming strategies for long-range competition are a bit more complicated, as this article explains…

U.S. F-Class Nationals Start Sunday, September 15th!
The U.S. Mid-Range and Long Range Nationals kick off September 15th at the NRA Whittington Center near Raton, New Mexico. Here are some tips that can help F-TR and F-Open shooters aim more precisely, and achieve higher scores. F-Class ace Monte Milanuk reviews reticle choices and strategies for holding off.

In our Shooters Forum, one newcomer wanted some advice on selecting a reticle for F-Class optics. He wondered about the advantage of Front (first) Focal Plane (FFP) vs. Second Focal Plane scopes and also wondered if one type of reticle was better for “holding off” than others.

In responding to this question, Forum regular Monte Milanuk provided an excellent summary of aiming methods used in F-Class. For anyone shooting score targets, Monte’s post is worth reading:

Aiming Methods for F-Class (and Long-Range) Shootingby Monte Milanuk

600-yard F-Class TargetF-Class is a known-distance event, with targets of known dimensions that have markings (rings) of known sizes. Any ‘holding off’ can be done using the target face itself. Most ‘benefits’ of Front (first) focal plain (FFP) optics are null and void here — they work great on two-way ranges where ‘minute of man’ is the defining criteria — but how many FFP scopes do you know of in the 30-40X magnification range? Very, very few, because what people who buy high-magnification scopes want is something that allows them to hold finer on the target, and see more detail of the target, not something where the reticle covers the same amount of real estate and appears ‘coarser’ in view against the target, while getting almost too fine to see at lower powers.

Whether a person clicks or holds off is largely personal preference. Some people might decline to adjust their scope as long as they can hold off somewhere on the target. Some of that may stem from the unfortunate effect of scopes being mechanical objects which sometimes don’t work entirely as advertised (i.e. one or two clicks being more or less than anticipated). Me personally, if I get outside 1-1.5 MOA from center, I usually correct accordingly. I also shoot on a range where wind corrections are often in revolutions, not clicks or minutes, between shots.

Some shooters do a modified form of ‘chase the spotter’ — i.e. Take a swag at the wind, dial it on, aim center and shoot. Spotter comes up mid-ring 10 at 4 o’clock… so for the next shot aim mid-ring 10 at 10 o’clock and shoot. This should come up a center X (in theory). Adjust process as necessary to take into account for varying wind speeds and direction.

John Sigler F-Class

600-yard F-Class TargetOthers use a plot sheet that is a scaled representation of the target face, complete with a grid overlaid on it that matches the increments of their optics — usually in MOA. Take your Swag at the wind, dial it on, hold center and shoot. Shot comes up a 10 o’clock ‘8’… plot the shot on the sheet, look at the grid and take your corrections from that and dial the scope accordingly. This process should put you in the center (or pretty close), assuming that you didn’t completely ignore the wind in the mean time. Once in the center, hold off and shoot and plot, and if you see a ‘group’ forming (say low right in the 10 ring) either continue to hold high and left or apply the needed corrections to bring your group into the x-ring.

Just holding is generally faster, and allows the shooter to shoot fast and (hopefully) stay ahead of the wind. Plotting is more methodical and may save your bacon if the wind completely changes on you… plotting provides a good reference for dialing back the other way while staying in the middle of the target. — YMMV, Monte

Flying with Firearms — Smart Advice for Traveling Competitors

Airport security travel bag check-in O'hare TSA

We know that many of our readers will soon travel by air to attend major matches in Raton, New Mexico. The Spirit of America Match runs September 7-13, and the F-Class Mid-Range and Long-Range Nationals follow September 15-22. If you’ll be venturing to Raton, or to another destination by air in the weeks ahead, you need to be careful when transporting firearms through airports both in the USA and in other countries. It is important that you comply with all Homeland Security, TSA, and Airline policies when transporting guns and ammunition. Following the rules will help ensure you (and your gear) make it to your destination without hassles, delays or (God forbid), confiscations.

Airport security travel bag check-in O'hare TSA
The NRA F-Class Mid-Range Nationals (Sept. 15-18) and Long Range Nationals (Sept. 19-22) will be held at the NRA Whittington Center 1000-Yard Range in Raton, New Mexico.

Good Advice from an Airport Police Officer
To help our readers comply with rules and regulations for air travel, we offer these guidelines, courtesy “Ron D.”, a member of our Shooters’ Forum. Before he retired, Ron D. served as a Police Officer assigned to Chicago’s O’Hare airport. Here Ron offers some very important advice for shooters traveling with firearms and expensive optics.

gun transport caseFirst, Ron explains that airport thieves can spot bags containing firearms no matter how they are packaged: “Don’t think you’re safe if your guns are placed in cases designed for golf clubs or trade show items. Baggage is X-Rayed now and cases are tagged with a special bar code if they contain firearms. It doesn’t take long for bad guys to figure out the bar coding for firearms.”

Carry-On Your Scopes and Expensive Items
Ron advises travelers to avoid placing very expensive items in checked baggage: “When traveling by air, carry on your rangefinder, spotting scope, rifle scope, medications, camera, etc. You would be surprised at the amount of people that carry-on jeans and shirts, but put expensive items in checked baggage. Better to loose three pairs of jeans than some expensive glass.”

Mark Bags to Avoid Confusion
Ron notes that carry-on bags are often lost because so many carry-on cases look the same. Ron reports: “People do accidentally remove the wrong bag repeatedly. I frequently heard the comment, ‘But it looks just like my bag.’ When de-planing, keep an eye on what comes out of the overhead that your bag is in. It’s easy to get distracted by someone that has been sitting next to you the whole flight. I tie two streamers of red surveyors’ tape on my carry-on bag.” You can also use paint or decals to make your carry-on bag more distinctive.

TSA Air transport safety locked bag declare firearm

General Advice for Air Travelers
Ron cautions: “Keep your hands on your items before boarding. One of the most often heard comments from theft victims was, ‘I just put my computer down for a minute while I was on the phone.’ Also, get to the baggage claim area quickly. If your family/friends can meet you there, so can the opportunists. Things do get lost in the claim area. Don’t be a Victim. Forewarned is forearmed.”

Important TSA Tips on Firearms and Flying

Choosing a Rifle Transport Case
Ron advises: “Buy the best [rifle case] that you can afford. Don’t cry when your $3,000+ Benchrest rifle has a cracked stock or broken scope. Think about what it would be like to travel across the country (e.g. to Montana or the Cactus Classic) and arrive with a damaged rifle. Remember the Samsonite commercial. (For you younger shooters, it shows a monkey throwing the suitcase around in his cage at the zoo.) Baggage handling is NOT a fine art. There is no guarantee that your rifle case will be on top of all the other baggage. Then there is shifting of baggage in the belly of the plane. Ponder that for a while. Rifle and pistol cases must be locked. It doesn’t take a Rocket Scientist to figure out that a simple pry tool will open most case locks. There is not much that you can do to disguise a rifle case. It is what it is, and opportunists know this. Among thieves, it doesn’t take long for the word to get around about a NEW type of case.”

Plano Double Rifle Case Amazon Airport security travel bag check-in O'hare TSA
This Plano Double Scoped Rifle Case offers the functionality and durability of an SKB-type hard case for HALF the money. This is now just $111.64, while the equivalent SKB is around $240.00.

Competitor’s POV perspective from a FCSA Match. Note the mirage.

By James Patterson
This article first appeared in Sinclair International’s Reloading Press Blog

For a number of years I drooled over every .50 BMG caliber rifle that I came across, I read every article I could find and determined that ‘Someday’ I was going to have one. Well I finally took the plunge and in 2002 I purchased my first ‘Big 50’. Almost immediately I joined the Fifty Caliber Shooters Association (FCSA) and I have since come to immensely enjoy shooting this challenging cartridge and associating with some of the best people on earth.

Dierks 50 BMG Light Class

FCSA Founded in 1985
FCSA Fifty Caliber ShootersThe FCSA, started in 1985, is an international organization with members in 22 countries. Headquartered in Monroe, Utah, the FCSA has a membership of approximately 4000. While the FCSA provides a service to military and law enforcement with research and instruction as well as an active liaison in both communities, the primary charter of the FCSA is the promotion of the sporting use of the 50 BMG cartridge and its wildcat derivatives. It has been the FCSA and its members who have lead the way in refining .50-caliber cartridges, rifles, and 1000-yard plus shooting know-how. Members enjoy a quarterly magazine, a suppliers directory, an active website with great photo galleries, and access to literally the best repository of 50 BMG information on the planet. If you are interested in Mr. John Browning’s big 50, you should seriously consider joining the FCSA.

Fifty Caliber shooter association fcsa national championship raton whittington NM new mexico
This interesting .50 Cal rig features a liquid-cooled barrel and unusual scope mounting arrangement.

While all aspects of the 50 BMG are promoted by the FCSA, the primary sport is 1000-yard competition. In 2010, there were 16 separate official matches scheduled across the USA, and many more ‘fun-shoots’. This sport is an incredible mix of the science, skill, and art of extreme long range accuracy. I had been actively shooting rifles and hunting for well over 40 years and had always considered myself a “rifle man”. But I had no idea of the learning curve that [faced me] when I first joined the FCSA.

FCSA 50-caliber shooting association

Historically, 1000-yard shooting has been primarily a benchrest activity but in the past several years we have seen a tremendous interest in ‘Hunter Class’ competition; this is shot prone using a bipod. This form of long range match shooting is excellent preparation for long range hunting. The required skill set [for ultra-long-range hunting] is guaranteed to humble even the most experienced rifleman.

FCSA 50 caliber Fifty Cal world championships

Cost of Big-Bore Shooting
Is owning and shooting a 50 BMG caliber rifle expensive? Relatively speaking yes, but one must put it into perspective. Rifles may run from $2500 to $8000, maybe even more for a top of the line custom rifle. A premium long-range scope will set you back $1800 to $3500. And while excellent .50 BMG commercial ammo is available, it runs $5 to $6 per round! Most serious shooters start reloading for the rifle as soon as practical, not only for the economics of reloading but also for the ability to fine tune custom ammo for their specific rifle. It’s a very rare match that is won shooting commercial ammo.

Wilkinson Dominates in Score at .50 Caliber FCSA Championships

Walter Wilkinson .50 BMG fifty caliber FCSA Raton New Mexico Whittington Center Steyr HS .50

Retired Army Special Forces Sgt. Maj. Walter Wilkinson won two of the four individual 1,000-yard Score titles — for Light Gun and Hunter Classes — at the recent Fifty Caliber Shooters’ Association (FCSA) 2018 World Championships. In addition to his two individual score titles*, Wilkinson was also a member of the winning 4-shooter team.

The FCSA World Championships were held July 5-7, 2018 at the NRA Whittington Center near Raton, New Mexico. There were shooters from Australia, Great Britain, Spain and the USA in attendance. The FCSA 1000-yard matches have four classes: Light Gun, Heavy Gun, Unlimited, and Hunter. In the first three classes, the rifles are normally shot from a machine rest off the bench. Hunter Class requires the shooter to fire from the ground with a bipod. And that’s how Wilkinson shot all his relays…

Steyr HS .50 BMG FCSA

Remarkably, Wilkinson, who shot his near-“box stock” Steyr HS .50 equipped with factory bipod from the ground in the prone position, posted the FCSA Championships’ highest score, beating out shooters in the Light Gun, Heavy Gun, and even Unlimited Classes.

Beating the Benchresters — While Shooting Prone from Bipod
Wilkinson, a Gunsite instructor from Edgewood, NM, shot a two-day total of 290-10X for the Hunter Score, and his Light Gun Score total of 291-7X was the highest of any shooter in any class — most of whom were firing custom-built rifles from mechanical rests atop concrete benches. Wilkinson also placed fourth overall in the 2-Gun Aggregate, which factors both scores and average group sizes from both classes. Wilksonson’s score wins marks his third FCSA victory in the Hunter Class with his Steyr HS .50 since his first win in 2012, and this year he notched his first Light Gun Score World Title.

The Wicked Whittington Range at Raton
Nestled at the base of the Sangre de Cristo Mountains, the Whittington Center’s 1,000-yard range has notoriously tricky winds, especially in the afternoons. On the first day, Wilkinson shot on the afternoon relays. As usual, switching and swirling winds proved to be a formidable foe for all shooters. Wind coming from behind the shooters was switching from 4 O’clock to 8 O’clock and back again, often changing within seconds. Wilkinson was able to very quickly make wind judgments and adjust his hold accordingly. “I couldn’t do anything wrong,” Wilkinson said. “It was like every time the wind changed, I knew exactly where to hold, and the bullets just kept going where I wanted them to.

Holding Off Right and Left for the Cycling Wind
“The highlights of the day were the last two strings of fire in Hunter Class during Relay 4″, Wilkinson explained. “I shot a 50-2X with a 9.8-inch group and a 49-2X with a 7.9-inch group. The Ten-Ring is right at 1.15 MOA, and when you keep them all in that, it says something about your rifle and your load. During both of those two strings, I changed from holding on the right side of the target to the left side during the string.”

Wilkonson’ Steyr .50-Cal has always been an accurate rig. Back in 2012, when Wilkinson developing loads, the big rig showed outstanding accuracy: “As I was working up a load for the HS.50, I shot groups that amazed me. I was getting groups of 0.214 MOA at 220 yards, and I didn’t know what to think. All the bullets were going in the same hole, and it was like ‘Wow, I’ve really got a rifle that can shoot here’. That stunned Wilkinson: “With my [military] experience with the performance of the same .50 BMG cartridge overseas, I didn’t expect that kind of accuracy out of it.”

Cost of Big-Bore Shooting
Is owning and shooting a 50 BMG caliber rifle expensive? Relatively speaking yes, but one must put it into perspective. Rifles may run from $2500 to $6000, maybe even more for a top of the line custom rifle. (Current MSRP for the Steyr H2 .50 is $5910.00). A premium long-range scope will set you back $1500 to $3000. And while excellent commercial ammo is available, it runs $3 to $5 per round! Most serious shooters start reloading for the rifle as soon as practical, not only for the economics of reloading but also for the ability to fine tune custom ammo for their specific rifle. It’s a very rare match that is won shooting commercial ammo.

*Wilkinson’s FCSA trophies state “Hunter Class Score World Champion” and “Light Class Score World Champion”. NOTE the FCSA also recognizes, for each class, a World Champion for Group size, AND a World Champion for combined Group and Score (Aggregate). Plus there are Championship Trophies for Two-Gun. This gets a little confusing. With other Disciplines there is only ONE World Champion per class, generally the competitor who has the best combination of Group Size and Score.

Shooting on a Spinning Planet — The Coriolis Effect

Whittington Coriolis Effect

The Coriolis Effect comes into play with extreme long-range shots like this (2100 yards at Raton, NM). The rotation of the earth actually moves the target a small distance (in space) during the long duration of the bullet’s flight.

Coriolis Effect Bryan Litz Applied BallisticsWhen you’re out at the range, the Earth seems very stable. But it is actually a big sphere zooming through space while spinning around its axis, one complete turn every 24 hours. The rotation of the earth can create problems for extreme long-range shooters. During extended bullet flight times, the rotation of the planet causes an apparent deflection of the bullet path over very long distances. This is the ballistics manifestation of the Coriolis Effect.

Bryan Litz of Applied Ballistics discusses explains the Coriolis Effect in his Ballistics Books and Seminars. Bryan notes that Coriolis is “a very subtle effect. People like to make more of it than it is because it seems mysterious.” In most common shooting situations inside 1K, Coriolis is not important. At 1000 yards, the Effect represents less than one click (for most cartridge types). Even well past 1000 yards, in windy conditions, the Coriolis Effect may well be “lost in the noise”. But in very calm conditions, when shooting at extreme ranges, Bryan says you can benefit from adjusting your ballistics solution for Coriolis.

Bryan explains: “The Coriolis Effect… has to do with the spin of the earth. You are basically shooting from one point to another on a rotating sphere, in an inertial reference frame. The consequence of that is that, if the flight time of the bullet gets significantly long, the bullet can have an apparent drift from its intended target. The amount [of apparent drift] is very small — it depends on your latitude and azimuth of fire on the planet.”

Coriolis Effect Bryan Litz Applied Ballistics

Coriolis is a very subtle effect. With typical bullet BCs and velocities, you must get to at least 1000 yards before Coriolis amounts to even one click. Accordingly, Bryan advises: “Coriolis Effect is NOT something to think about on moving targets, it is NOT something to think about in high, uncertain wind environments because there are variables that are dominating your uncertainty picture, and the Coriolis will distract you more than the correction is worth.”

“Where you could think about Coriolis, and have it be a major impact on your hit percentage, is if you are shooting at extended range, at relatively small targets, in low-wind conditions. Where you know your muzzle velocity and BC very well, [and there are] pristine conditions, that’s where you’re going to see Coriolis creep in. You’ll receive more refinement and accuracy in your ballistics solutions if you account for Coriolis on those types of shots. But in most practical long-range shooting situations, Coriolis is NOT important. What IS important is to understand is when you should think about it and when you shouldn’t, i.e. when applying it will matter and when it won’t.”

The Coriolis Effect — General Physics
The Coriolis Effect is the apparent deflection of moving objects when the motion is described relative to a rotating reference frame. The Coriolis force acts in a direction perpendicular to the rotation axis and to the velocity of the body in the rotating frame and is proportional to the object’s speed in the rotating frame.

A commonly encountered rotating reference frame is the Earth. The Coriolis effect is caused by the rotation of the Earth and the inertia of the mass experiencing the effect. Because the Earth completes only one rotation per day, the Coriolis force is quite small, and its effects generally become noticeable only for motions occurring over large distances and long periods of time. This force causes moving objects on the surface of the Earth to be deflected to the right (with respect to the direction of travel) in the Northern Hemisphere and to the left in the Southern Hemisphere. The horizontal deflection effect is greater near the poles and smallest at the equator, since the rate of change in the diameter of the circles of latitude when travelling north or south, increases the closer the object is to the poles.

For sheer “Fun with Firepower” it’s hard to beat a 3-Gun match at Raton, New Mexico. You get to play with lots of guns — rifles, pistols, and shotguns — while enjoying great views in one of North America’s most scenic shooting facilities. This past weekend many of the nation’s top 3-Gun aces were in Raton for the 2017 Rocky Mountain 3-Gun World Championship. This was held August 10-13 at the Whittington Center facility. Stages were conducted both on the designated rifle ranges as well as nearby hillsides.

In 3-gun matches, all stages are “on the clock”. Competitors need to be FAST and accurate.

There was a lot of Army black and yellow on the top of the podium, with USAMU shooters winning two divisions, along with the Team Event. SSG Joel Turner won the Open Division and SSG Tyler Payne won the Heavy Metal Scope Division. SFC Daniel Horner placed second in the Tactical Scope Division, while SFC Kyle McMaster finished second in the Tactical Irons Division. All four soldiers teamed up to win the Team Relay Shoot-Off competition to close out the event.

Run ‘N Gun at 6000 feet
The Rocky Mountain 3-Gun (RM3Gun) is an action shooting match in the natural terrain of the NRA Whittington Center near Raton, NM. The riverbeds, mountains, trees and rocks provide props for the stages. There are 5 divisions: Open, Tactical Scope, Tactical Iron, He-Man Scope, and He-Man Iron.

RM3Gun is a very physical match, and Whittington’s 6000′ altitude makes things even tougher. The pace, thin air, and terrain challenge competitors’ fitness levels. The match has a healthy amount of long range rifle shooting. The match organizers state: “We try to strike a balance between rifle, shotgun and pistol, but you will definitely have lots of rifle because it’s one of the only places you can shoot as far in such a beautiful environment. Usually, we have some moving/aerial targets for the shotgun as moving targets are what the gun is designed for.”
