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.
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.
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.”
This popular video, viewed over 3.3 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.
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 articles first cover the history of the AR-15, and then explain how AR-platform accuracy can be optimized. 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.
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.
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.
Over the past 12 months, this article was one of the TOP TEN most-read Daily Bulletin features. We’re reprising it today for those who may have missed it the first time. The above diagram comes from a TiborasurasRex YouTube Video comparing G1 and G7 BC models. CLICK HERE to watch the video.
The better, up-to-date ballistics programs let you select either G1 or G7 Ballistic Coefficient (BC) values when calculating a trajectory. The ballistic coefficient (BC) of a body is a measure of its ability to overcome air resistance in flight. You’ve probably seen that G7 values are numerically lower than G1 values for the same bullet (typically). But that doesn’t mean you should select a G1 value simply because it is higher.
Some readers are not quite sure about the difference between G1 and G7 models. One forum member wrote us: “I went on the JBM Ballistics website to use the web-based Trajectory Calculator and when I got to the part that gives you a choice to choose between G1 and G7 BC, I was stumped. What determines how, or which one to use?”
The simple answer is the G1 value normally works better for shorter flat-based bullets, while the G7 value should work better for longer, boat-tailed bullets.
G1 vs. G7 Ballistic Coefficients — Which Is Right for You?
G1 and G7 refer both refer to aerodynamic drag models based on particular “standard projectile” shapes. The G1 shape looks like a flat-based bullet. The G7 shape is quite different, and better approximates the geometry of a modern long-range bullet. So, when choosing your drag model, G1 is preferrable for flat-based bullets, while G7 is ordinarily a “better fit” for longer, boat-tailed bullets.
Drag Models — G7 is better than G1 for Long-Range Bullets
Many ballistics programs still offer only the default G1 drag model. Bryan Litz, author of Applied Ballistics for Long Range Shooting, believes the G7 standard is preferrable for long-range, low-drag bullets: “Part of the reason there is so much ‘slop’ in advertised BCs is because they’re referenced to the G1 standard which is very speed sensitive. The G7 standard is more appropriate for long range bullets. Here’s the results of my testing on two low-drag, long-range boat-tail bullets, so you can see how the G1 and G7 Ballistic coefficients compare:
G1 BCs, averaged between 1500 fps and 3000 fps:
Berger 180 VLD: 0.659 lb/in²
JLK 180: 0.645 lb/in²
The reason the BC for the JLK is less is mostly because the meplat was significantly larger on the particular lot that I tested (0.075″ vs 0.059″; see attached drawings).
For bullets like these, it’s much better to use the G7 standard. The following BCs are referenced to the G7 standard, and are constant for all speeds.
Many modern ballistics programs, including the free online JBM Ballistics Program, are able to use BCs referenced to G7 standards. When available, these BCs are more appropriate for long range bullets, according to Bryan.
[Editor’s NOTE: BCs are normally reported simply as an 0.XXX number. The lb/in² tag applies to all BCs, but is commonly left off for simplicity.]
Ian Klemm, 2017 F-TR USA National Champion, is one of America’s top F-Class shooters, both shooting individually and in team competition. Ian is known for his consistency, smooth gun handling, and an uncanny ability to shoot well even in the toughest wind conditions. In this Vortex Video, Ian and fellow long-range shooter Niles Richardson, reveal some of their competitive secrets, and wind-reading techniques. This video focuses primarily on F-Class competition but Ian and Niles also talk more broadly about the myriad factors that contribute to rifle accuracy. Topics include: match strategies, wind and mirage reading, barrel harmonics, bipods, and optics.
Vortex Nation Podcast Episode 57 Summary
From Vortex: Our original intent was to have just a podcast about the sport of F-Class shooting, but when you get these brainiacs (Ian Klemm and Niles Richardson) talking about their obsession… er… “Hobby” you better believe it’s going to turn into a full on long range shooting information assault to the brain. Fact of the matter is, in F-Class, the only thing that matters is long range accuracy – and when we say “Accuracy”, we’re talking about sub-MOA groups on paper at 1000 yards with .308 Wins. Every single aspect of an F-Class competitor’s game is completely dialed in for long range accuracy.
We talk about the guns, their bipods, wind, mirage, barrel harmonics and the special scopes F-Class competitors need for their rifles. Ian even goes so far as to tell us how much his rifle has moved prior to the bullet leaving his 30-inch barrel. Just a simple equation involving acceleration, terminal velocity, moment of inertia of the rifle and coefficient of friction of the bipod and rifle on the ground.
Want to learn long-range benchrest skills from the best in the business? Then head to Williamsport, PA this June. The registration period for the 2019 PA 1000 Yard Benchrest School is now open. This year’s session will be held Saturday and Sunday, June 8-9, 2019, with a “Meet and Greet” on Friday night, June 7. Classes, taught by top 1K shooters, are held at the Original Pennsylvania 1000-Yard Benchrest Club Range, one of the best 1000-yard ranges in the country. The school will be limited to 24-30 students with one instructor for every two students.
Praise from a 1K Benchrest School Grad
Here’s a testimonial from a recent graduate: “I can attest to the knowledge that you gain. I went last year and loved it. Have renewed my membership in the Club and would love to go this year. I would love to take the course again. In the photo above I am in the back row, fourth from the right — sunglasses and blue shirt.” — Bob, Class of 2016
Participants will learn all aspects of long-range benchrest shooting from some of the most skilled marksmen in the country. Much time is spent at the loading bench and on the firing line. Classes cover load development, precision reloading, bench skills, and target analysis. You don’t even need guns and ammo — all equipment and ammunition will be provided.
School instructors tell us: “This year’s benchrest school will be a 2-day weekend event. (There is also an optional ‘Meet and Greet’ gathering Friday evening). The school is a beginner class designed to teach the fundamental skills needed to be competitive at at 600 and 1000 yards. Saturday will be spent in class covering a range of topics including reloading ‘dos and don’ts’, load development and equipment handling. Sunday we will shoot an actual match to see what you’ve learned.”
After taking this class, you might be the guy who shoots an amazing 100-8X at 1000 yards like this:
Cost for the class is $475.00 including lunches on Sat/Sun and dinner on Saturday. Act soon if you want to attend the 2019 school — the program fills quickly. The classroom is limited to only 24 (possibly 30) students and instruction is one instructor per two students. A one year membership is included with the cost of the school.

AccurateShooter.com offers dozens of FREE, printable targets for target practice, load development, and fun shooting. We also offer a few of the most popular NRA Bullseye targets. One or more of these printable targets should work for most training purposes. However, some readers have asked: “Where can we get the real targets… exactly like the ones used in NRA, IBS, and NBRSA shooting matches?”
All these vendors carry nearly all the NRA High Power and Smallbore targets, including the new, smaller F-Class targets. Germany’s Kruger Targets sells all the important NRA targets, and international (ISSF) air rifle and smallbore targets too.
Orrville Printing currently sells IBS targets for rimfire (50 yard) benchrest, short-range centerfire Benchrest (100, 200, 300 yards), Hunter BR Rifle (100, 200, 300 yards), plus the official 600-yard and 1000-yard IBS targets. National Target Company also has most of the IBS targets. NBRSA short-range, 600-yard, and 1000-yard benchrest targets are available directly from the NBRSA Business Office. Call (307) 655-7415 to order for the season.
At Western CMP Games, veteran rifle competitors Leon Rutherford, left, and Don Rutherford, demonstrate how to score targets at the GSM new shooter clinic. Note the use of a separate Target Center, which is available from many of the vendors listed above.

At the 2018 National Matches at Camp Perry this past summer, the Civilian Marksmanship Program (CMP) introduced a new series of Long Range events. Three days of long range rifle matches, held at 800, 900 and 1,000 yards, were added to the summer 2018 schedule to allow long range marksmen the opportunity to fire on the Camp Perry grounds following the NRA’s decision to move the NRA High Power Long Range Championship (and HP Championship) to Camp Atterbury, Indiana. Long Range matches will be held again at Camp Perry next year, from August 6-9, 2019 — put those dates on your calendar.
Camp Perry Photo by Scott McKenna from past event.
Competitors at the 2018 Long Range Matches at Camp Perry fired in Service, Match, and Palma rifle classes. Six matches were fired during the Long Range series. Those who participated in the inaugural LR matches were pleased that Long Range was featured again at Camp Perry after a two-year absence:
“Camp Perry is one of the best ranges in the U.S. with a long and proud history. Thank you, CMP, for all of the work expended on the 2018 season.”
“The matches were well-organized and went smoothly.”
“I liked the fact that they were held at Camp Perry. That’s where the National Matches should be.”
“Good job! I enjoyed the matches. It was great being back at Perry for long range.”
“Overall a very positive and fun championship for me. I applaud your efforts in bringing long range back to Camp Perry….”
Winning the overall Aggregate was USAMU shooter SFC Shane Barnhart with 1244-71X. Teammate SGT Lane Ichord won the service rifle division with 1228-48X, while Robert Steketee topped the Palma rifle class with 1233-56X. As the “top gun” for the match, SFC Barnhart was the first recipient of the Coats Brown Memorial Trophy – donated to the CMP by the Military Marksmanship Association. Chief Warrant Officer 4 Coats Brown, was a repeat National Matches champion and became the head coach of the newly-formed Army Marksmanship Unit in 1956.
John Whidden cleaned the Viale Memorial event with the match rifle, with a score of 200-12X. Robert Gill, 59, of Visalia, CA, led the Palma rifle portion. The Bataan Memorial 4-person Team Match, which included 20 shots by each member at 1,000 yards, saw wins from the AMU in both the match and service rifle categories. Members of AMU Green (SFC Barnhart, SFC Brandon Green, SGT Ben Cleland, and SSG Amanda Elsenboss), each dropped only one point in the match rifle class to record an Aggregate score of 796-54x.
Major Sponsors for Camp Perry Long Range Matches
Geissele Automatics served as a generous sponsor for the new Long Range events, donating a prize to every winner in each category. Capstone Precision, the parent company of Berger, Lapua, SK and Vihtavuori, also donated prizes to several winners during the National Long Range Matches.
SAVE THE DATE in 2019: The CMP’s Long Range Matches will take place August 6-9 at Camp Perry, in Port Clinton, Ohio. Events include three days of Individual Long Range Matches, two days of Team Matches, the Camp Perry Palma Match, Shooter’s Reception and Long Range Awards Ceremony.
The better, up-to-date ballistics programs let you select either G1 or G7 Ballistic Coefficient (BC) values when calculating a trajectory. The ballistic coefficient (BC) of a body is a measure of its ability to overcome air resistance in flight. You’ve probably seen that G7 values are numerically lower than G1 values for the same bullet (typically). But that doesn’t mean you should select a G1 value simply because it is higher.
