Minute of Angle (MOA) Explained by Informative Video

one minute of angle

This popular video, viewed over 1.1 million times on YouTube, provides a clear explanation of Minute of Angle (MOA) and how that angular measurement is used. Among novice shooters, there is much confusion over this term. In this NSSF Video, Ryan Cleckner, a former Sniper Instructor for the 1st Ranger Battalion, defines the term, “Minute of Angle” (MOA) and explains how you can adjust for windage and elevation using 1/4 or 1/8 MOA clicks on your scope. This allows you to sight-in precisely and compensate for bullet drop at various distances.

For starters, Ryan explains that, when talking about angular degrees, a “minute” is simply 1/60th. So a “Minute of Angle” is simply 1/60th of one degree of a central angle, measured either up and down (for elevation) or side to side (for windage). At 100 yards, 1 MOA equals 1.047″ on the target. This is often rounded to one inch for simplicity. Say, for example, you click up 1 MOA. That is roughly 1 inch at 100 yards, or roughly 4 inches at 400 yards, since the target area measured by 1 MOA increases in linear fashion with the distance.

IBS Match Report: 2017 1000-Yard Nationals in West Virginia

IBS 1000-yard Nationals White Horse West Virginia

2017 IBS 1000-Yard Benchrest Nationals
Report By Boyd Allen
On September 1-4, the IBS held its 2017 1000-yard Benchrest Nationals at the Whitehorse Shooting Center in Peeltree, West Virginia. There was a great turn-out this year, with 118 entries in Light Gun Class (17-lb limit, 5 shots per target) class and 107 shooters in Heavy Gun Class (Unlimited weight, 10 shots per target). The conditions this year were challenging to say the least, with rain storms, spiraling winds, and fog. In fact, rain and fog on Saturday (with cancelled relays) caused the Nationals to be extended by one day through Monday, September 4th. What’s more, of the 107 shooters listed in the Two-Gun Overall results who actually shot both guns, there were dozens of DQs. (Yes, the wind was a bit tricky at this year’s Nationals.)

Congratulations to the “top guns” at the Nationals: Edward Kenzakoski (Two-Gun Overall Champion), Mike Gaizauskas (Light Gun Overall, plus LG Score Agg), and Mike Brennan (Heavy Gun Overall, plus HG Score Agg). Group Agg winners were Richard Schatz for LG, and Charlie Lentz for Heavy. Two ladies also deserve mention. Sally Bauer shot the smallest group of the match, a 1.923″ 5-shot group in LG — that’s 0.184 MOA! Ruth Edwards drilled a 2.104″, also mighty impressive. Nice shootin’ ladies…

White Horse Wind and Weather Factors — and Topography
The firing line for the 1000-yard range has a covered structure with 14 well-spaced masonry benches with block bases and cast concrete tops. Facing southwest, the firing line is above the land between it and the target butts, which are at the head of a canyon. There is a low area with trees on the left with an elevated flat area on the right.

This topography create unpredictable wind patterns that can change rapidly with no warning. Those changes can wreak havoc with competitors’ groups and scores. The wind direction at the targets can be opposite that at the firing line, with the result that a let-off down range not only carries the penalty of making a hold-off incorrect, but because the wind at the firing line can continue, adding the additional penalty of a reversal. This was the common cause of disqualifications, which were numerous at this year’s Nationals.

Delay Caused by Fog and Rain
On Saturday, rain and fog delays, caused the match to be extended through Monday. The rules dictate that if a full match cannot be finished because of weather, then all of the day’s results are discarded. This meant that even those shooters who completed their relays on Saturday had to shoot them over — hence another day was added to the event. Because of the prospect of worsening conditions on Saturday afternoon, even though there was daylight left, the decision was made to extend the match through Monday.

Profile of 2017 IBS 1000-Yard National Champion Edward Kenzakoski

Commenting on his performance at the Nationals, Ed said modestly:
“I didn’t shoot really good. I just shot better than them other guys.”

IBS 1000-yard Nationals White Horse West Virginia

Winning Hardware (with a 110-lb Heavy Gun)
Notably, Ed does all of his own gunsmithing, and he built his Championship-winning rifles. Both guns featured 1:11″-twist, 30″ Krieger barrels. (LG: 1.250″ shank and .950 muzzle; HG: 2″ contour untapered). Ed’s Light Gun has a BAT action, no barrel block, Jewell trigger, and McMillan Tooley MBR stock. His Heavy Gun boasts a 10″-long BAT action in a two-piece aluminum stock with barrel block. That HG beast weighs 110 pounds! Both of Ed’s rifles (light and heavy) wore Nightforce 12-42x56mm BR scopes.

Winning Numbers
To win the Two Gun Overall, Ed posted 137 LG Score, 262 HG Score, and 399 Two-Gun Score Agg. His Group numbers were: LG Group 5.659, HG Group 7.483, Two-Gun Agg: 6.571.

Winning Loads and Reloading Methods
Both rifles are chambered in 300 WSM. Ed shoots 210gr Berger VLDs (sorted every way possible), with Norma brass, Hodgdon H4350 powder, and CCI BR2 primers. For the two guns he used very different seating depths — barely touching for the HG, 0.100″ jump for the LG. He said that it takes him a full four days to load the ammunition for both rifles for a match. Yes, he weighs primers, and he even passes his bullets through a .309 bushing.

No Dark Horse at White Horse — Kenzakoski is a Proven Winner
One shouldn’t be surprised at Edward Kenzakoski’s success. Ed really cleaned up at Williamsport this year, winning one 6-match Aggregate and two 10-match score and group Aggregates. He also established a new Williamsport club Light Gun record of 3.2″.

Record-Setting Asymmetry
In 2016 Michael Gaizauskas set the current 1000-yard IBS Heavy Gun (10 shot) group and score records. He set those records with the rifle on the left (below), then chambered in 6.5×47 Lapua. In this match, Mike won LG Group and LG Overall with the rifle on the right as chambered in his own 7mm short magnum wildcat. Mike designed and built both these distinctive assymetric stocks.

White Horse Shooting Center Facilities, Organization, and Location
The 1000-yard range used at the IBS 2017 Nationals is part of a large shooting facility run by Whitehorse Firearms Outdoor Education Center in cooperation with the West Virginia Division of Natural Resources. White Horse is located off of Route 20 near the small community of Peeltree, WV. The nearest town of any size, ten miles to the south, is Buckhannon, WV, which has about 5600 residents.

White Horse Geography and Climate
The White Horse range is set in wooded hill country, with lots of creeks and some smaller rivers all kept green and running by an annual rainfall of about 48 inches and about the same for snowfall. To my eyes it is beautiful county, pleasingly rural and lush, in marked contrast to where I live where every plant must be served by some sort of irrigation.

Hard-Holders Set Records in Montana Long Range Tournament

Deep Creek Long Range Tournament
Deep Creek is a beautiful range, lined with tall timber on both sides.

Report by Jamey Williams
The second phase of the Northern Rockies Long Range Tournament was held at the Deep Creek Range outside Missoula, Montana last weekend. The F-Class portion was held two weekends before, under very different but also favorable conditions. The F-Class event was at the tail end of a very bad fire year, and the conditions were hot, dry, and at times, smoky. Nonetheless, great scores were fired, including a pending National Team Record by the Washington F-Open Team.

This past weekend was very different, with low temps, rain, and fog — a very dramatic shift in a very short time. The 1000-yard team matches on Friday took place under a light rain, and several cleans were fired — a prelude of thing to come. Saturday brought cold conditions and fresh snow on the surrounding mountains. While it was cold and cloudy, several shooters fired high scores with some only dropping only a handful of points or less over the Palma match and the 1000-yard match. This brought us into Sunday morning with a fog starting to settle over the range during the 800 yard stage of the last Palma match. As the day went on, the conditions gradually improved and with some outstanding shooting, a couple of pending NRA National Records were set.

This past weekend was time for the sling-shooters, the “hard-holders” who shoot prone with sling, coat, and glove. There were some very impressive performances — including two pending records, one by an All National Guard marksman SSG John Coggshall, and the other by Kerry Spurgin, who shot incredibly well, to break a long-standing Open Record.

Deep Creek Long Range Tournament
Note: The upper left image shows SSG Coggshall at Deep Creek in 2010.

SSG John Coggshall of the Connecticut Army National Guard and member of the All National Guard Rifle Team fired an outstanding 1093-61X (out of a possible 1100 points), earning him the NRA Silver medallion. This score should earn him the Service Category National Record for the Long Range Regional Aggregate by one point and a bunch of Xs over the previous record set by SGT Eric Smith, USAR. SSG Coggshall previously held this record, which was set several years ago at the Deep Creek Range in Montana. Along with Palma rifle, Coggshall has a lot of experience shooting smallbore as well as service rifle. His Team Coach described him as a hard-holder who can hold half the X-Ring with his iron-sighted Palma rifle.

Also having a fantastic weekend was U.S. Palma Team member, Kerry Spurgin of Hillsboro, Oregon. Spurgin (above center) was an All-American Rifle Team shooter for Murray State University in Kentucky, and brother to Patricia Spurgin, 1984 Olympic air rifle Gold medalist. Spurgin started out day three of the tournament with an strong score fired in mildly foggy conditions at the 800-yard line, a 149-14X. He continued to fire very well, and ended the individual matches with the Gold Medallion and a pending Open and Civilian record score of 1097-75X. With less than perfect conditions, Spurgin managed to only drop three (3) points all weekend, breaking a National Record that had stood for 17 years.

Deep Creek Range
The Deep Creek Range in Missoula, MT is one of the nicest places to shoot in the Intermountain West region. The range is located in the mountains within a few minutes drive of Missoula, and there is camping on-site. When conditions are good at Deep Creek, records get broken.

King of the Range Combo Match: Long Range and 3-Gun Shooting

Nosler October King of Range Match 3-Gun Long Range

We’ve seen new shooting disciplines emerge in recent years (3-Gun, PRS, ELR to name a few) and now we’re seeing another trend — shooting matches that combine action shooting with precision Long Range competition. The latest and greatest example of that is the Nosler King of the Range event slated for late October in Oregon. 3-Gun, Long Range, and a combined match title will all be up for grabs in this two-day, combo event. Competitors can shoot either the 3-Gun or Long Range match, or shoot both, going after the title of “King of the Range”.

Nosler October King of Range Match 3-Gun Long Range

It is unusual for a 3-Gun action match to be combined with a long-range competition, because few venuea offer the right combination of terrain and facilities for both disciplines. Mason Payer, Nosler Marketing Manager says: “The size and varied terrain of the COSSA park facility [near Bend, OR] presents the opportunity to combine both 3-Gun and Long Range, making this a truly multi-discipline match that will be fun for and challenging for everyone.”

The Nosler King of the Range, presented by MGM Targets and COSSA, will be a combined-match format, spread over two days of competition. Day One will feature 5 or 6 stages of 3-Gun, while Day Two will be comprised of 5-6 stages of Long Range, for both Bolt Guns and Gas Guns.

Nosler King of the Range Course of Fire:
Day 1: Match consists of 5-6 stages of 3-Gun that run anywhere from 30 to 160 seconds.
Day 2: Long Range 5-Stage Match with Bolt Guns out to 1000 yards and Gas Guns out to 800 yards.
NOTE: Separate rifles can be used for the 3-Gun half and the Long Range half.

Nosler October King of Range Match 3-Gun Long Range

The Nosler Cup 3GN Long Range Match will be comprised of approximately 10 stages of challenging precision shooting. This will be a standard 3-Gun match running concurrent with the long range match. Ten stages with 6-8 rifle targets per stage, and 4-10 pistol targets on most stages.

CLICK HERE to Register for the Nosler Cup 3GN Long Range Match.

The Nosler Cup 3-Gun Match, hosted by COSSA, will be a one-day competition, featuring 5-6 stages of running and gunning. Shooters will have the opportunity to shoot on Saturday OR Sunday (either day).

The 2017 F-Class World Championships wrapped up August 17 with the final day of Team competition. Over the past two days, 8-shooter squads competed in the major international challenge match while 4-shooter teams vied for honor in the Rutland match. Team USA F-TR stole the show with a stirring come-from-behind victory over a very strong Australia F-TR squad. Not to be denied, Aussie F-Open shooters countered America’s F-TR success with a solid win for Australia in the 8-shooter F-Open match. It was Deja Vu… this result was a replay of the 2013 Worlds, where Team USA won the F-TR Team Title, while Team Australia won F-Open.

Along with winning F-Open, the Aussies did well in the 8-man F-TR competition, finishing second overall with a score of 3394-237V, six points behind Team USA F-TR (3400-264V). Third in F-TR was Team South Africa, with 3376-250V.

Rutland F-Class World Championship

Team Canada (3506-346V) finished second in F-Open, while Team USA (F-Open) finished third with the interesting score of 3500-350V (that’s not a misprint). We believe Calvin Waldner of Canada had the top individual F-Open score for the match — 444-51V.

The F-TR Team Battle — It Paid to Wait
The top two F-TR squads, Team USA and Team Australia, followed very different strategies. The Australians got off to a quick start, while the Americans waited… and waited … and waited. Being patient and waiting for more readable and stable wind conditions proved a winning strategy for the Yanks who overcame a 9-point deficit to finish with a six-point margin as time closed down in the firing period.

Team USA Captain Ray Gross reports: “The match came down to the last yard line. The Australians were up 11 points to start the day and the Canadians were 6 points behind. We made up 2 points at 700m and shot even with the Australians at 800m, leaving us 9 points down going into the final 900m stage.

The Aussies chose to start shooting right away in what looked liked easy conditions and we waited, hoping for better. While we waited the team stayed focused and ready. Luck was on our side, it calmed down and the shooters and coaches performed flawlessly, making up the nine points and finally pulling ahead in the last few minutes of the match.

We were the last team on the line shooting and everyone was behind us watching. After two days of very close competition, the match was not decided until our last two shooters. Our last shooter started with only 12 minutes left in the match and he finished his string of 15 shots in about five minutes. He only dropped two points giving us a six point victory.

We were so focused on delivering our best performance that we weren’t sure how the other teams had finished. After the last shot the Australian captain came over and congratulated me. They had been watching our score after they had finished and knew that we had won the match. Our gritty determination had paid off and it had been one of the most exciting matches that I’ve ever been a part of. Everyone on the team should be proud that they did not let our slim chances discourage them going into that last yard line. They stayed focused and each delivered a top performance.”

American F-Open Squads Dominate 4-Shooter Rutland Match

In the F-Open Rutland competition for 4-shooter teams, American squads dominated, taking the top 4 places. Team USA Blue (1758-177V) won the Rutland title, edging Spindle Shooters by a slim one-point margin. In third place was Team USA Red followed by the Texas State Rifle Association team.

In F-TR Rutland competition, Team “Da Bulls” secured a very convincing win. Da Bulls’ 1709-131V score was a full 14 points ahead of Team KP Ballistics. This was sort of an American victory… though Da Bulls did have one Canadian “ringer” on the squad, Stephen Ireland of Toronto. Runner-up KP Ballistics was just the opposite — KP had all Canadian members except one Yank, Wade Fillingame of New Hampshire.

Long Range Shooting: Video Series with Bryan Litz

Bryan Litz Video Long Range large caliber rifles

Getting started in long-range shooting? Need some pointers on gun set-up and hardware options? Bryan Litz of Applied Ballistics has created a helpful series of videos for the NSSF covering long range shooting. Bryan, 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 2016 King of 2 Miles event. Here are four (4) videos, each covering a topic of interest for long-range shooters. Running 3-4 minutes each, these videos can help you get started, and invest wisely when acquiring your next long-range rifle, scope, and accessories.

Long Range Precision — The Keys to Success

TIP for Plotting Long Range Trajectories: You want to know the true, actual ballistic coefficients of your loads. The BCs listed by manufacturers for their projectiles may be somewhat unreliable — the real BC could be higher or lower (and BC can change with velocity). That can result in problems at longer distances. Using sophisticated equipment, Applied Ballistics has measured true BCs for hundreds of projectiles. Plugging these verified numbers into your Ballistics App can improve your hit percentage at long range.

Tools of Choice — Purpose-Built Long Range Rifles

TIP for Choosing a Rifle: When you’re selecting a rifle for long range shooting, it’s important to understand your application and objectives. The applications for long-range shooting can be very refined. You have to select all the details of your application to select the correct rifle. Here are two examples — a semi-auto AR-platform rifle with scope and a bolt-action Fullbore (Palma) rifle with aperture sights. There are many other long range disciplines — F-TR for example. The F-TR rig uses a bipod and rear bag and a scope. To be competitive, a modern F-TR rig should shoot well under half-MOA.

Equipment Advice — Upgrading Your Hardware

TIP for Upgrading Your Rifle: At some point factory rifle owners will recognize weak links in the equipment chain. You can run that factory rifle for quite some time, but the barrel is eventually what’s going to hold you back. The twist-rate may not be high enough to stabilize the high-BC bullets. So the first thing you’re going to want to upgrade is the barrel. You want to get a fast twist-rate barrel with a chamber that is optimized for the bullet you’ll be shooting. A good-quality, custom barrel will be easier to clean, and it will improve the overall accuracy and precision of your shooting.

Big Boomers — Large-Caliber Rifles for Long Range

TIP for Shooting Hard-Recoiling Rifles: Bryan Litz defines “Large Caliber” as .338 caliber and bigger. These rifles can shoot heavy bullets with high BCs. However there are some trade-offs. It can be hard to maintain good fundamentals of marksmanship (trigger control, sight alignment) when you’re fighting heavy recoil and burning 100+ grains of powder. You’re dealing with the challenges that high energy brings. You want a muzzle brake with any cartridge .338 or above. Also, when considering lathe-turned solid bullets, remember that these typically have less sectional density compared to lead-cored bullets with similar profiles. This affects ballistics as well as recoil energy.

.338 Lapua Magnum Barrel Cut-Down Velocity Test

.338 Lapua Magnum LM barrel length vs velocity cut down test chrono rifleshooter.com
Shooters contemplating purchase of a .338 LM rifle often ask: “What length barrel should I get?” Rifleshooter.com recently performed a test that provides interesting answers…

Our friends at RifleShooter.com like to slice and dice — barrels that is. They have done barrel length cut-down tests for popular calibers like the .223 Rem, 6.5 Creedmoor, and .308 Winchester. But now they’ve tackled something way bigger — the .338 Lapua Magnum, a true “Big Boomer”. Starting with a beefy 30″-long Pac-Nor Barrel, RifleShooter.com chopped the tube down in one-inch increments all the way down to 17 inches (that’s 14 different lengths). At each new (shorter) barrel length, velocity was measured with a MagnetoSpeed chronograph using two different loads, 250gr SMKs with H4831sc and 300gr SMKs with Retumbo. Four shots were fired at each length with each load, a total of 112 rounds.

Load #1: 250gr Sierra MK, Lapua brass, CCI #250 primer, H4831SC, OAL 3.720″.
Load #2: 300gr Sierra MK, Lapua brass, Win WLRM primer, Retumbo, OAL 3.720″.

The .338 Lapua Magnum is a jumbo-sized cartridge, that’s for sure…

Donor Barrel Sacrificed for Science
Rifleshooter.com’s Editor explains: “Brandon from Precision Addiction offered to send us his .338 barrel for our .338 Lapua Mag test. I took him up on his offer and he sent me his used Pac-Nor chrome-moly barrel with about 600 rounds though it. This thing was a beast! A heavy 1.350″ shank that ran straight for 6″, until tapering to 1″ at 30″ in length.”

.338 Lapua Magnum LM barrel length vs velocity cut down test chrono rifleshooter.com

Results Summary

.338 Lapua Magnum with 250gr Sierra MatchKings
After shortening the barrel from 30″ to 17″, total velocity reduction for the 250-grainers was 395 FPS, an average loss of 30.4 FPS per 1″ cut. The amount of velocity loss per inch rose as the barrel got shorter, with the biggest speed reduction, a loss of 55 FPS, coming with the cut from 18″ to 17″.

Start Velocity: 2942 FPS | End Velocity: 2547 FPS | Average Loss Per Inch: 30.4 FPS

.338 Lapua Magnum with 300gr Sierra MatchKings
Shooting the 300-grainers, total velocity reduction was 341 fps, an average of 26.2 FPS loss per 1″ cut (30″ down to 17″). However, the speed actually increased with the first cut from 30 inches to 29 inches. The tester noted: “The 300 SMK load showed a slight increase from 30″ to 29″. I’ve recorded this in other tests and it seems to be more common with a heavier load. I suspect it is primarily due to the small sample sizes being used along with the relative proximity of muzzle velocities in adjacent lengths.”

Start Velocity: 2833 FPS | End Velocity: 2492 FPS | Average Loss Per Inch: 26.2 FPS*

*Velocity rose with first cut. Velocities ranged from 2,871 FPS (29″) to 2,492 FPS (17″) for a total velocity loss of 341 FPS.

RifleShooter.com crunched the velocity numbers in some interesting ways. For example they analyzed rate of velocity loss, concluding that: “after the initial rate change, the rate of the change in velocity is fairly consistent.” (View Rate of Change Graph)

How Velocity Loss Alters Long-Range Ballistics
The testers wanted to determine how the velocity reductions “affect our ability to hit targets downrange”. So, Rifleshooter.com plotted changes in elevation and wind drift at all barrel lengths. This revealed something interesting — drift increased significantly below 26″ barrel length: “Above 26″ things look pretty good, below 22″ they change quickly.”

We highly recommend you read the whole story. Rifleshooter.com put in serious time and effort, resulting in solid, thought-provoking results. The data is presented in multiple tables and graphs, revealing inch-by-inch velocities, change “deltas”, and SDs at each length.

Shooting FAILS — Why Marksmen Miss at Long Range

Bryan Litz Applied Ballistics Long Range Shooting Error Wind Call Kestrel Laser Rangefinder

Applied Ballistics has produced a series of YouTube videos about precision long range shooting. Featuring ace long-range shooter and professional ballistician Bryan Litz, these videos address various topics of interest to long-range marksmen. This featured video looks at Long Range mistakes — Bryan Litz reveals the most common ballistics-related shooting errors at Long Range. And then Bryan explains how to improve your shooting (and wind reading) to eliminate those common errors.

Watch Applied Ballistics Video about Common Mistakes in Long Range Shooting:

Bryan Litz of Applied Ballistics often hears the question: “What are the main reasons people miss their target at long range?” To answer that question, in this video, Bryan explains the most important variables in Long Range shooting. Bryan says: “Probably the number one thing is range — you have to have a [precise] range to your target because your bullet is dropping, and to hit the target you need to correct for bullet drop.” Distance may be indicated on the target bay (or berm), but for open ranges you should ascertain distance-to-target with a quality laser rangefinder. Even when the distance to target is shown with a sign or marker, you may want to confirm the distance with your rangefinder. (You may be surprised — we’ve seen marked target distances at commercial ranges off by 25+ yards!) Bryan says: “Get a good laser range to the target and you’ll be within a couple yards”.

Bryan Litz Applied Ballistics Long Range Shooting Error Wind Call Kestrel Laser Rangefinder

After distance to target, the most important variable is the wind. This is the most challenging factor because the wind is constantly changing. Bryan explains: “After 300 or 400 yards, the wind [will] move your shots off the target if you don’t correct for it. The best way to account for the wind is to measure it at your location with a Kestrel. The Kestrel can give you the speed and direction of the wind at your location, which can baseline your wind call for your long-range shot.” Bryan acknowledges that there will still be variables: “The wind isn’t always blowing the same downrange as at your location… and the wind is always changing”. Bryan notes that you need to account for variances in wind between the time you gauge the wind angle and velocity and the time you actually you take your shot.

South Texas marksmanship trainingThere is an excellent article about Mirage on the South Texas Marksmanship Training Center (STMTC) website. This article explains what causes mirage and how mirage can move the perceived aiming point on your target. Most importantly, the article explains, in considerable detail, how you can “read” mirage to discern wind speeds and wind directions.

Mirage Is Your Friend
While hot days with lots of mirage can be frustrating, mirage can reveal how the wind is flowing (and changing). If you learn how to recognize and read mirage patterns, you can use that information to shoot higher scores. That’s why many leading long-range shooters tell us: “Mirage is your friend.” As the STMTC article explains: “A mirage condition is not a handicap, since it offers a very accurate method of perceiving small wind changes[.]”

Mirage Illustrated with Diagrams
With simple but effective graphic illustrations, this is one of the best explanations of mirage (and mirage reading) we have found on the internet. This is a “must-read” for any serious competitive shooter. Here is a brief sample from the article, along with an illustration. NOTE: the full article is six times longer and has 8 diagrams.

South Texas Mirage Wind Diagram displacement

The term “mirage” as used by the shooter does not refer to a true mirage, but to heat waves and the refraction of light as it is bent passing through air layers of different density. Light which passes obliquely from one wind medium to another it undergoes an abrupt change in direction, whenever its velocity in the second medium is different from the velocity in the first wind medium; the shooter will see a “mirage”.

The density of air, and therefore its refraction, varies with its temperature. A condition of cool air overlaying warm air next to the ground is the cause of heat waves or “mirage”. The warm air, having a lower index of refraction, is mixed with the cooler air above by convection, irregularly bending the light transmitting the target image to the shooter’s eye. Figure 1 shows (greatly exaggerated) the vertical displacement of the target image by heat waves.

South Texas Mirage Reading article

Heat waves are easily seen with the unaided eye on a hot, bright day and can be seen with spotting scope on all but the coldest days. To observe heat waves, the scope should be focused on a point about midway to the target. This will cause the target to appear slightly out of focus, but since the high power rifle shooter generally does not try to spot bullet holes, the lack in target clarity is more than compensated by clarity of the heat waves.

Zediker Examines Long Range Shooting with AR-Platform Rifles

AR15 ar-15 long range

Looking to shoot an AR-platform rifle out past 500 yards? Then you should read two articles by AR guru Glen Zediker. Author of The New Competitive AR-15 and The Competitive AR15 Builders Guide, Zediker is an expert when it comes to AR-platform rifles. Glen believes ARs have excellent long-range capability, provided they are built to high standards, with good barrels. Glen says: “a properly configured AR-15 is easily capable of good performance at 500+ yards. Good performance means it can hit a 1-foot-square target all the time. Competitive shooters can cut that standard in nearly half (the X-Ring on an MR1 600-yard NRA High Power Rifle target is 6 inches, and high X-counts are commonplace among more skilled shooters).”

Published in the Cheaper than Dirt Shooter’s Log, Zediker’s pair of articles cover the history and upgrading of the AR-15. Part One reviews the AR’s development as an accurate firearm, tracing its evolution from a Vietnam-era combat weapon to what is now a favored target rifle of High Power competitors. READ PART ONE.

Long Range AR AR-15 Glen Zediker Cheaper than dirt

Part Two discusses the specifics that make an AR accurate at 500 yards and beyond. Zediker talks about barrel configuration (profile and twist rate), bullet selection, floating handguards, and proper mounting of optics or iron sights. READ PART TWO.

Long Rang AR AR-15 Glen Zediker Cheaper than dirt

Here are some highlights from Long-Range AR-15 Part TWO:

Barrel Twist Rate
To stabilize anything longer than a 68- or 69-grain bullet, the barrel twist rate must be — at minimum– 1-in-8. Twist rates reflect how far the bullet travels along the lands or rifling to make one complete revolution. So, 1-in-8 (or 1-8, 1:8) means “one turn in eight inches.” I think it’s better to go a little faster in twist. There is nothing wrong with a 1:7 twist. The 90-grain bullets require a 1:6.5, and that is getting on the quick side. If you want to shoot Sierra 77s or equivalent, and certainly anything longer, 1:8 is necessary. By the way, it is bullet length, not weight, which constitutes the necessary twist rate to launch a stable bullet.

Optics Mounting
Correct optical sight positioning can be a challenge. With a flattop upper, I need a good inch additional forward extension at the muzzle side of the upper for the sight mount bases to avoid holding my head “back” to get the optimal view through the scope. A longer rail piece is necessary for my builds as a result.

Buttstock Length and Adjustment
An adjustable buttstock is valuable, and even more valuable if it’s well-designed. Mostly, a standard stock is too short, and the cheek area sits too low. Adding length helps a lot by itself. There are assemblies that replace the standard buttplate to allow for length and, usually, height and rotation adjustments for the buttpad. An elevation-adjustable cheekpiece is a big help to attain a solid position.

5 Degrees of Doom — The Danger of Over-Shooting the Berm

Gun Angle long range

In our Shooters’ Forum, there was an discussion about a range that was threatened with closure because rifle over-shoots were hitting a farm building over two miles from the firing line. One reader was skeptical of this, asking “how’s that possible — were these guys aiming at the stars?” Actually, you may be surprised. It doesn’t take much up-angle on a rifle to have a bullet land miles down-range. That’s why it’s so important that hunters and target shooters always orient their barrels in a safe direction (and angle). Shooters may not realize how much a small tilt of the barrel (above horizontal) can alter a bullet’s trajectory.

How many degrees of muzzle elevation do you think it would take to hit a barn at 3000 yards? Ten Degrees? Twenty Degrees? Actually the answer is much less — for a typical hunting cartridge, five to seven degrees of up-angle on the rifle is enough to create a trajectory that will have your bullet impacting at 3000 yards — that’s 1.7 miles away!

Gun Angle long range

Five degrees isn’t much at all. Look at the diagram above. The angle actually displayed for the up-tilted rifle is a true 5.07 degrees (above horizontal). Using JBM Ballistics, we calculated 5.07° as the angle that would produce a 3000-yard impact with a 185gr .30-caliber bullet launched at 2850 fps MV. That would be a moderate “book load” for a .300 Win Mag deer rifle.

Here’s how we derived the angle value. Using Litz-derived BCs for a 185gr Berger Hunting VLD launched at 2850 fps, the drop at 3000 yards is 304.1 MOA (Minutes of Angle), assuming a 100-yard zero. This was calculated using a G7 BC with the JBM Ballistics Program. There are 60 MOA for each 1 degree of Angle. Thus, 304.1 MOA equals 5.068 degrees. So, that means that if you tilt up your muzzle just slightly over five degrees, your 185gr bullet (2850 fps MV) will impact 3000 yards down-range.

Figuring Trajectories with Different Bullets and MVs
If the bullet travels slower, or if you shoot a bullet with a lower BC, the angle elevation required for a 3000-yard impact goes up, but the principle is the same. Let’s say you have a 168gr HPBT MatchKing launched at 2750 fps MV from a .308 Winchester. (That’s a typical tactical load.) With a 100-yard zero, the total drop is 440.1 MOA, or 7.335 degrees. That’s more up-tilt than our example above, but seven degrees is still not that much, when you consider how a rifle might be handled during a negligent discharge. Think about a hunter getting into position for a prone shot. If careless, he could easily touch off the trigger with a muzzle up-angle of 10 degrees or more. Even when shooting from the bench, there is the possibility of discharging a rifle before the gun is leveled, sending the shot over the berm and, potentially, thousands of yards down-range.

Hopefully this article has shown folks that a very small amount of barrel elevation can make a huge difference in your bullet’s trajectory, and where it eventually lands. Nobody wants to put holes in a distant neighbor’s house, or worse yet, have the shot cause injury. Let’s go back to our original example of a 185gr bullet with a MV of 2850 fps. According to JBM, this projectile will still be traveling 687 fps at 3000 yards, with 193.7 ft/lbs of retained energy at that distance. That’s more than enough energy to be deadly.

New Video Series from Applied Ballistics

Bryan Litz Applied Ballistics Long Range Shooting Video Youtube elevation transonic supersonic

Applied Ballistics has created a series of YouTube videos about precision long range shooting. Featuring ace long-range shooter and professional ballistician Bryan Litz, these videos will address various topics of interest to long-range marksmen. In this video, the first in the series, Bryan Litz answers the question, “Just What Is Long Range Shooting?” Bryan discusses how we define “long range” and the key factors shooters need to consider.

Applied Ballistics Video — What Is Long Range Shooting?

Bryan states: “I don’t think there is a clear definition of where Long Range starts.” But he offers this practical guideline: “The way I think of it, any time you’re making major adjustments to your zero in order to hit a target, due to gravity drop and wind deflection, THEN you’re getting into ‘Long Range’. For example, if you are zeroed at 100 yards and need to shoot to 600 yards, you have many feet of elevation [drop] to account for, and to me, that’s where it becomes Long Range.”

Extended Long Range and the Transonic Zone
Bryan adds a second concept, namely “Extended Long Range”. Litz says that: “Extended Long Range starts whenever the bullet slows to its transonic range. As the bullet slows down to approach Mach 1, it starts to encounter transonic effects, which are more complex and difficult to account for, compared to the supersonic range where the bullet is relatively well-behaved.” Bryan notes that bullets start to encounter transonic effects at about 1340 fps, quite a bit faster than the speed of sound, which is about 1116 fps at sea level in normal conditions (59° F).

Sierra Offers New Ultra-High-BC 197gr 7mm (.284) MatchKing

Sierra 197gr MatchKing High BC F-Open Closed Meplat

Get ready for a revolution in the F-Open, ELR, and Long-Range Benchrest games. Sierra just introduced a new 7mm bullet with a stunning 0.780 G1 BC. This new 197-grain HPBT MatchKing is one of the highest-BC, jacketed .284-caliber projectiles ever offered to the public. By comparison, Sierra’s own advanced 183-grain 7mm Matchking has a .707 G1 BC. That means the new 197-grainer has a 10% higher BC than the already slippery 183-grainer. That’s an impressive achievement by Sierra.

We expect top F-Open and long-range shooters will be trying the new 197-grainer as soon as they can get their hands on this new projectile. They may need new barrels however, as Sierra states: “This bullet requires a barrel twist rate of 1:7.5″ or faster”. Sierra expects to start shipping these slippery 7mm 197s very soon. You can order directly from Sierra’s website, stock code #1997, $54.20 for 100 bullets.

Sierra 197gr MatchKing

Factory Uniformed Bullet Tips
Sierra has officially announced that the 197gr SMK will come “pointed” from the factory. These impressive new 197s will have a “final meplat reducing operation” (pointing). This creates a higher BC (for less drag) and also makes the BC more uniform (reducing vertical spread at long range). Our tests of other factory-pointed Sierra MKs have demonstrated that Sierra does a very good job with this pointing operation. The “pointed” MatchKings we’ve shot recently had very nice tips, and did hold extremely “tight waterline” at 1000 yards, indicating that the pointing process does seem to enhance BC uniformity. Morever, radar-derived “real-world” BCs have been impressively uniform with the latest generation of pointed Sierra MKs (such as the new 110gr 6mm MatchKing).

Here is the statement from Sierra about the new bullets:

Shooters around the world will appreciate the accuracy and extreme long range performance of our new 7mm 197 grain HPBT (#1997). A sleek 27-caliber elongated ogive and a final meplat reducing operation (pointing) provide an increased ballistic coefficient for optimal wind resistance and velocity retention. To ensure precise bullet to bore alignment, a unique bearing surface to ogive junction uses the same 1.5 degree angle commonly found in many match rifle chamber throats.

While they are recognized around the world for record-setting accuracy, MatchKing® and Tipped MatchKing® bullets are not recommended for most hunting applications. Although MatchKing® and Tipped MatchKing® bullets are commonly used for varmint hunting, their design will not provide the same reliable explosive expansion at equivalent velocities in varmints compared to their lightly jacketed Hornet, Blitz BlitzKing, or Varminter counterparts.

How to Spot Trace — The Bullet’s Wake Signature

NSSF long range shooting bullet trace spotting scopeHave you ever seen bullet trace? Do you know how to read trace? Well watch this NSSF video to learn how to recognize trace, and use trace to help adjust your aim on the target. Watch the video from 1:50 to 2:20 to see trace in slow motion. Watch carefully starting and you can see the trace in the milli-seconds before the bullet hits the target.

Rod Ryan of Storm Mountain Training Center explains how to read bullet trace: “If you’re looking through your spotting scope, and you focus on your target, and then back off about a quarter-turn counter-clockwise (in most cases) you’ll be able to focus a little closer to you and you’ll actually see this movement of air — it’s called the trace — going down range.”

Watch the Slow-Mo Trace Starting at 1:50. From 2:10 to 2:20 you can actually see the bullet hanging in the air just before it hits the target.

Trace is easier to see when there’s some moisture in the air. By following the bullet trace you can see if you shot is running high or low, left or right, even if you can’t see a shot imparct on the target. This is important, particularly when you’re attempting an steep-angled shot and it’s hard to see bullet impact on the ground near the target. Rod Ryan explains: “A lot of times we have an angular hill-top and you’re shooting directly into a [steep] drop [so] you can’t see any splash at all or any dirt flow after the miss happens. In this case the last thing you see is that trace.”

What you’re seeing is akin to the wake that forms behind a motorboat, but it is a trail of disturbed air rather than disturbed water. Ryan says: “It’s just like you’re looking down from space at a motorboat in the water, you can see that wake. Very close to the target, you can actually see it roll in… if you’re taking a shot at say… four, five, six hundred yards, it’s very prevalent, you can see it very well.”

Aiming Techniques for Long-Range Competition

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…

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

Sierra Introduces New 195-grain, .30-Caliber Tipped MatchKing

Sierra .30 .308 30-cal caliber Tipped MatchKing TMK bullet G1 BC F-TR long range .30-cal

Sierra has just announced a new, high-BC .30-caliber projectile. This provides a very interesting new option for F-TR competitors and long-range benchrest shooters. The new 195-grain Tipped MatchKing (TMK) boasts an impressive 0.610 G1 Ballistic Coefficient. That compares well with any conventional bullet in this caliber and weight range. The key to the high BC is the green acetal resin tip that lowers drag while making the BC more consistent for every bullet in the box. NOTE: This .30-caliber 195 grain TMK requires a twist rate of 1:10” or faster to stabilize.

Sierra .30 .308 30-cal caliber Tipped MatchKing TMK bullet G1 BC F-TR long range .30-cal

The new 30 cal. 195 grain Tipped MatchKing® bullets will be available in 500-ct boxes (product #7795C) with a $243.84 MSRP as well as 100-ct boxes (product #7795) with MSRP of $51.19 per box. Note, this new 195gr TMK is designed for competition use — primarily as a paper-puncher. Sierra says: “Tipped MatchKing® bullets are not recommended for most hunting applications.”

Optics Expertise: MIL and MOA Terminology Defined

Mil MOA reticle ranging PRS tactical minute angle precision rifle series
Visit PrecisionRifleBlog.com for a discussion of MIL vs. MOA.

Many guys getting started in long range shooting are confused about what kind of scope they should buy — specifically whether it should have MIL-based clicks or MOA-based clicks. Before you can make that decision, you need to understand the terminology. This article, with a video by Bryan Litz, explains MILS and MOA so you can choose the right type of scope for your intended application.

This March-FX 5-40x56mm Tactical FFP scope features 0.05 MIL Clicks.
Mil MOA reticle ranging PRS tactical minute angle precision rifle series

You probably know that MOA stands for “Minute of Angle” (or more precisely “minute of arc”), but could you define the terms “Milrad” or “MIL”? In his latest video, Bryan Litz of Applied Ballitics explains MOA and MILs (short for “milliradians”). Bryan defines those terms and explains how they are used. One MOA is an angular measurement (1/60th of one degree) that subtends 1.047″ at 100 yards. One MIL (i.e. one milliradian) subtends 1/10th meter at 100 meters; that means that 0.1 Mil is one centimeter (1 cm) at 100 meters. Is one angular measurement system better than another? Not necessarily… Bryan explains that Mildot scopes may be handy for ranging, but scopes with MOA-based clicks work just fine for precision work at known distances. Also because one MOA is almost exactly one inch at 100 yards, the MOA system is convenient for expressing a rifle’s accuracy. By common parlance, a “half-MOA” rifle can shoot groups that are 1/2-inch (or smaller) at 100 yards.

What is a “Minute” of Angle?
When talking about angular degrees, a “minute” is simply 1/60th. So a “Minute of Angle” is simply 1/60th of one degree of a central angle, measured either up and down (for elevation) or side to side (for windage). At 100 yards, 1 MOA equals 1.047″ on the target. This is often rounded to one inch for simplicity. Say, for example, you click up 1 MOA (four clicks on a 1/4-MOA scope). That is roughly 1 inch at 100 yards, or roughly 4 inches at 400 yards, since the target area measured by an MOA subtension increases with the distance.

one MOA minute of angle diagram

MIL vs. MOA for Target Ranging
MIL or MOA — which angular measuring system is better for target ranging (and hold-offs)? In a recent article on his PrecisionRifleBlog.com website, Cal Zant tackles that question. Analyzing the pros and cons of each, Zant concludes that both systems work well, provided you have compatible click values on your scope. Zant does note that a 1/4 MOA division is “slightly more precise” than 1/10th mil, but that’s really not a big deal: “Technically, 1/4 MOA clicks provide a little finer adjustments than 1/10 MIL. This difference is very slight… it only equates to 0.1″ difference in adjustments at 100 yards or 1″ at 1,000 yards[.]” Zant adds that, in practical terms, both 1/4-MOA clicks and 1/10th-MIL clicks work well in the field: “Most shooters agree that 1/4 MOA or 1/10 MIL are both right around that sweet spot.”

Eye in the Sky — Drone Video of 1122-Yard AR15 Shooting Session

Texas .223 Rem Drone Video 1000 Yards Gorilla Ammo

Many of our readers have never had a chance to shoot much past 600 yards. How far away does a 1000-yard+ target really seem to the naked eye? Well this short video answers that question. Gorilla Ammo, the video’s producers, used a camera-carrying aerial drone to fly downrange from the firing line all the way out to 1122 yards (and back again). Watch the drone footage at 0:00-0:07 and especially 0:48-1:03. The “bird’s-eye view” really gives you a sense of the distance. The “fly-back” at 0:48-1:03 time-mark is what makes this video worth watching.

The video features prone shooting at steel targets placed at 750 and 1122 yards. We do apologize for the lame, “oh so serious” voice-over which attempts to make this rather ordinary range session seem like some kind of life-changing experience. (Frankly, you may just want to turn the sound off — it’s that annoying.) It’s really not that big a deal to hit steel at 750 yards with a quality AR-15, chambered in .223 Rem, shooting Sierra 77 grain MatchKings.

Texas .223 Rem Drone Video 1000 Yards Gorilla Ammo

Hitting Steel at 1122 Yards with 2540 FPS Ammo Can Be Challenging
The 1122-yard hits are a bit more impressive. Gorilla Ammo lists a relatively sedate 2540 fps Muzzle Velocity for its .223 Rem 77gr SMK ammunition. According to JBM Ballistics, at 1125 yards, that 2540 fps load has 68.3 MOA of drop from a 100-yard zero (firing at sea level and 80° F ambient). Morever the bullet goes trans-sonic around 750 yards (losing stability) and is traveling just 933 fps at impact. And the wind’s the killer — at 1125 yards, with this bullet/load, a mere 2 mph, full-value wind change can move the Point of Impact over three feet!
