World Record group shot by Bart Sauter in IBS 600-yard Match on April 21, 2018 in Memphis, TN.

0.282 inches, 0.04 MOA… at 600 Yards. Simply amazing…

What can we say… this 0.282″ 5-shot group 600 yards represents one of the most impressive feats of rifle accuracy in history. Shot in competition, this five-shot group at 600 yards easily fits inside a dime with plenty of room to spare!

Bullet-maker Bart Sauter recently shot this 0.282″ five-shot group at a 600-yard IBS match. Yep, you read that right — 0.282″ at 600. Most shooters would be happy with that group at 100 yards. At 200 it would be remarkable. But at 600 — it is truly amazing. Readers, 0.282″ at 600 works out to 0.04 Minutes of Angle (MOA). Not point four MOA, but point ZERO four MOA, and it was all in the TEN RING for a 50 score. Even measured outside edge to outside edge, that group is just 0.525″, so Bart’s group will easily fit inside a dime (0.705″ diameter).

Sauter’s amazing 0.282″ 50 group smashes the existing IBS Heavy Gun 600-yard record, a 0.404″ shot by John Lewis way back in 2008. It also happens to beat the existing IBS Light Gun group record — the stunning 0.336″ by Rodney Wagner in 2013. (A group many said could never be bettered). Bart’s group will be a new score record too — many 50s have been shot before, but the group size is the tie-breaker, and no one has ever shot smaller at 600 than Bart.

Sauter Smashes IBS World Records with Stunning 600-Yard Group

Report by Boyd Allen, IBS Vice President
On the 21st of April, at the beautiful Memphis Sport Shooting Assn. 600-yard benchrest range, bullet-maker Bart Sauter made history. About 11:00 O’clock with 12-15 MPH switchy winds, Bart Sauter waited for his chosen condition and then ran five shots into an incredible 0.282″ record-breaking group, with a score of 50. Shot in Heavy Gun Class (with his Light Gun), this combination of group and score bettered the previous HG group and score records with sufficient margins that their records in both categories are virtually guaranteed. The previous group record, a 0.404″, belonged to John Lewis and stood for ten years. The previous score record was 50/.513 (group size being the tie breaker) shot by B.J. Francis last year. Bart’s target was 50/.282.

To put it in perspective Bart’s record has the equivalent angular dispersion (MOA) of a .04″ group shot at 100 yards. (Bart’s exact MOA is 0.0448) But consider that crosswinds have roughly 36 times more effect at 600 yards than at 100 yards (by the “Rule of the Square”).

Record-Setting Cartridge and Load with Bart’s Own 105gr Bullets
Bart shot a 6mmBR Ackley Improved (6BRA) wildcat cartridge with an 0.272″ neck. This is basically the 6mmBR Norma with a 40° shoulder. The neck is long like the parent cartridge, not short like a 6mm Dasher. Bart was shooting his own 105 grain, 13 Ogive VLD bullets. He calls this new bullet design “The Hammer” (for good reason). Bart’s Hammer 105s were loaded in Lapua brass with Hodgdon H4895 powder and Wolf primers. Bullet tips were trimmed on a Giraud bullet point trimmer, but not pointed. Bart feels that there is too much potential for damaging bullets during pointing, so he does not point his match bullets. Bart had his LabRadar chrono on the bench during the match. Velocities were 2970-2975 fps with single-digit ES.

Record-Setting Rifle — IBS Light Gun Shot in Heavy Gun Class
Bart’s rifle features a melonited BAT B action, with a 26″, 1:8″-twist, HV contour James Lederer barrel, fitted with a Mike Ezell tuner. The Jewell trigger was set to 1.5 ounces. On top was a March 40X in BAT rings. The initial build was by Mike Moses, with chambering by Dean Stroud, and final (glue and screw) bedding by Billy Stevens. The handsome wood JB 1000 stock (3″-wide fore-end) boasts an aluminum keel added by Alex Wheeler after the initial build. Bart said that it only took him 15 minutes to adjust the keel so that the cross hairs did not wiggle on the target when the gun was pulled back a full 2 ½ inches. Bart is definitely a fan of the adjustable keel.

Bench Equipment and How Rifle Was Shot
Bart used a Farley Coaxial front rest with soft leather Edgewood front back sprinkled with baby powder. In the back was a Protektor Model DR rear bag with Cordura ears and no added lube (not needed with aluminum keel) borrowed from Mike Moses. Bart shot the rifle lightly pinned between his shoulder and the fore-end stop. Interestingly, Bart kept his Labradar chronograph on his bench throughout the day, and recorded velocities during the record group: 2970-2975 fps with single-digit ES.

Bart Sauter IBS .282 World Record Group benchrest H4895 600 yards heavy gunReloading Equipment and Methods
After firing, cases are annealed with a Benchsource flame annealer. The inside of the case-necks are brushed with a nylon brush (no lubricant is used). Cases are sized with a custom Whidden Full-length sizing die (with bushings), and a cut-down Wilson micrometer seater that was originally made for the Dasher.

Bullets are seated with a 21st Century Shooting Hydro Bullet Seater, used with the Wilson cut-down Wilson seating die. This state-of-the-art arbor press boasts a hydraulic seating pressure cylinder and gauge. During seating, the force gauge reads about 27.

The powder charge is first thrown from a manual measure and usually trickled onto an A&D 120 FXi magnetic force restoration scale using an Adams automatic trickler, but this time Bart had to settle for his old RCBS trickler because the drive band of the Adams auto-trickler wore out.

Brass Prep — The chamber is a 0.272″ no turn. Bart lightly skims the necks AFTER the first firing just enough to achieve batch to batch uniformity in neck thickness. He uses a .266 bushing which gives him .003 neck tension.

Pre-Loading vs. Loading at the Range
I asked Bart if he pre-loads, or loads at the range. Unexpectedly his answer was “Both…depending”. Bart will identify his “in tune” velocity at his home range and then pre-load that load before the match. However, Bart takes all of his reloading equipment to the match, and if the conditions are such that his pre-loaded ammunition does not give the velocity he wants (as revealed by the LabRadar), he will load at the match.

Another test that he feels is important is to be able to pass a bullet all the way through the neck of his fired cases. Bart thinks that even if the shank of a seated bullet does not directly contact a doughnut, that doughnut can have a negative effect on accuracy.

Bart has brought short range benchrest know-how to 600-yard competition. He uses a full set of short range flags, shown above. At last year’s Nationals, at the same Memphis range, Bart was one of the only shooters with a set of flags. Now other 600-yard competitors are following suit.

Final Throughts — The 6BR Ackley vs. 6mm Dasher
Given its prominence, it is inevitable that comparisons be made between the 6mmBR Ackley Improved and the Dasher. On this subject Bart told me that, based on his experience, he is a “Dasher basher”. He believes the Dasher can be finicky, and has a tendency to flip shots out of the group. For Bart, the 6BR Ackley has been a lot easier to work with and more predictable.

Below is a test target Bart shot at 100 yards. The load yielding the smallest 3-shot group, measuring 0.092″, was the load Bart took to the match. As you can see, the positions of the various load adjustments did not change on the targets. Bart said that that is the kind of positive compensation that he likes to see.

While Bart does most of load testing at short range, he can shoot out to 500 yards near his home. He says his record-setting gun has produced multiple 500-yard, 3-shot groups in the “three-quarter inch range” when testing in calm conditions. That’s 0.14 MOA for three shots. At 500…

Congratulations to Bart on His Great Shooting
Finally, I would like to add my congratulations to Bart Sauter for this spectacular group. I also want to thank Bart for generously taking the time to share the details of his load, reloading methods, and rifle components. Bart has shown that applying some short-range benchrest techniques to the mid-range game can produce remarkable results.

If You’re Not Using Wind Flags You’re Throwing Away Accuracy


Forest of Windflags at World Benchrest Championships in France in 2011

There’s a simple, inexpensive “miracle device” that can cut your groups in half. If you’re not using this device, you’re giving away accuracy. The “miracle device” to which we refer is a simple wind indicator aka “windflag”. Using windflags may actually improve your accuracy on target much more than weighing charges to the kernel, or spending your life savings on the “latest and greatest” hardware.

Remarkably, many shooters who spend $3000.00 or more on a precision rifle never bother to set up windflags, or even simple wood stakes with some ribbon to show the wind. Whether you’re a competitive shooter, a varminter, or someone who just likes to punch small groups, you should always take a set of windflags (or some kind of wind indicators) when you head to the range or the prairie dog fields. And yes, if you pay attention to your windflags, you can easily cut your group sizes in half. Here’s proof…

Miss a 5 mph Shift and You Could DOUBLE Your Group Size

The table below records the effect of a 5 mph crosswind at 100, 200, and 300 yards. You may be thinking, “well, I’d never miss a 5 mph let-off.” Consider this — if a gentle 2.5 mph breeze switches from 3 o’clock (R to L) to 9 o’clock (L to R), you’ve just missed a 5 mph net change. What will that do to your group? Look at the table to find out.

shooting wind flags
Values from Point Blank Ballistics software for 500′ elevation and 70° temperature.

Imagine you have a 6mm rifle that shoots half-MOA consistently in no-wind conditions. What happens if you miss a 5 mph shift (the equivalent of a full reversal of a 2.5 mph crosswind)? Well, if you’re shooting a 68gr flatbase bullet, your shot is going to move about 0.49″ at 100 yards, nearly doubling your group size. With a 105gr VLD, the bullet moves 0.28″ … not as much to be sure, but still enough to ruin a nice small group. What about an AR15, shooting 55-grainers at 3300 fps? Well, if you miss that same 5 mph shift, your low-BC bullet moves 0.68″. That pushes a half-inch group well past an inch. If you had a half-MOA capable AR, now it’s shooting worse than 1 MOA. And, as you might expect, the wind effects at 200 and 300 yards are even more dramatic. If you miss a 5 mph, full-value wind change, your 300-yard group could easily expand by 2.5″ or more.

If you’ve already invested in an accurate rifle with a good barrel, you are “throwing away” accuracy if you shoot without wind flags. You can spend a ton of money on fancy shooting accessories (such as expensive front rests and spotting scopes) but, dollar for dollar, nothing will potentially improve your shooting as much as a good set of windflags, used religiously.

Quarter-MOA, Half-MOA? How Much Precision Is Really Enough?

Jim See Elite Accuracy
This impressive 15-round group was shot by Jim See of Elite Accuracy.

Different shooting disciplines demand different levels of precision/accuracy. In the rapid-fire 3-Gun game, you could probably “clean” most stages with a 2-MOA rifle. By contrast, in the short-range group benchrest game, to compete with the best, you’ll need a rifle that shoots in the “ones” (i.e. 0.1-0.19 MOA) in perfect conditions. In 1000-yard F-Class competition, the top shooters want a rifle that will hold one-third-MOA of vertical at that distance.

What is your standard of accuracy? How good is “good enough”. Jim See, a skilled gunsmith and successful PRS competitor, has answered that question for his tactical discipline. For the kind of matches Jim shoots, he likes to have a rifle that will hold half-MOA for five (5) shots, 3/4-MOA for 15 shots, and 1 MOA for twenty shots. Remarkably, Jim’s rifle can do that with factory ammo. Above is an impressive 15-shot group shot with .260 Remington Federal Premium Ammo.

Jim See Elite Accuracy

“I say it all the time, my loads need to print 5 under 1/2″, 10 under 3/4″, and 20 under 1″. It’s simple, if a hot barrel will keep 20 rounds fired in succession under my standard it will be a good barrel and load for Precision Match Shooting. Federal Premium Gold Metal Match .260 with Sierra bullets made the cut for me today. 15 consecutive shots under 3/4 MOA.” –Jim See

It’s said that you “can never have too much accuracy”, but there are acceptable standards for each discipline, and they’re not the same. A 100/200 yard Benchrest shooter will be sorely disappointed with a rifle/ammo set-up that can only deliver half-MOA. On the other hand, a PRS competitor like Jim See can achieve great success with a lesser degree of precision. This means you can save time and money. You can run your barrels longer between cleanings, and you don’t have to go “full OCD” when loading your ammo. The PRS shooter does not need to weigh-sort primers, or load powder to single-kernel standards. Proof is the performance. Jim See recently took third place at the Spearpoint Shootout, and he has been a podium finisher at other events. Learn more about Jim’s gunsmithing and training operations at EliteAccuracy.com.

Jim’s target seemed a bit familiar. AccurateShooter.com created this Diamond and Dot Target a few years back. On each aiming point, there are high-contrast black horizontal and vertical lines for aligning your cross-hairs. The gray circle lets you see the bullet impacts above, without obliterating the red diamond, which is quite useful for precise aiming (we put fine cross-hairs on the points of the diamond). This target sheet includes data entry tables below each of the three aim points. There are many other free targets out there, but this format is very popular. We’re pleased to see Jim using it.

Toast in Six Seconds — The Brutal Truth of Short Barrel Life

Stopwatch barrel life

This thought-provoking article is one of the 15 most popular Daily Bulletin features over the last 12 months. We are republishing this story today for readers who may have missed it the first time around…

Here’s a little known fact that may startle most readers, even experienced gunsmiths: your barrel wears out in a matter of seconds. The useful life of a typical match barrel, in terms of actual bullet-in-barrel time, is only a few seconds. How can that be, you ask? Well you need to look at the actual time that bullets spend traveling through the bore during the barrel’s useful life. (Hint: it’s not very long).

Bullet-Time-in-Barrel Calculations
If a bullet flies at 3000 fps, it will pass through a 24″ (two-foot) barrel in 1/1500th of a second. If you have a useful barrel life of 3000 rounds, that would translate to just two seconds of actual bullet-in-barrel operating time.

Ah, but it’s not that simple. Your bullet starts at zero velocity and then accelerates as it passes through the bore, so the projectile’s average velocity is not the same as the 3000 fps muzzle velocity. So how long does a centerfire bullet (with 3000 fps MV) typically stay in the bore? The answer is about .002 seconds. This number was calculated by Varmint Al, who is a really smart engineer dude who worked at the Lawrence Livermore Laboratory, a government think tank that develops neutron bombs, fusion reactors and other simple stuff.

On his Barrel Tuner page, Varmint Al figured out that the amount of time a bullet spends in a barrel during firing is under .002 seconds. Al writes: “The approximate time that it takes a 3300 fps muzzle velocity bullet to exit the barrel, assuming a constant acceleration, is 0.0011 seconds. Actual exit times would be longer since the bullet is not under constant acceleration.”

We’ll use the .002 number for our calculations here, knowing that the exact number depends on barrel length and muzzle velocity. But .002 is a good average that errs, if anything, on the side of more barrel operating life rather than less.

So, if a bullet spends .002 seconds in the barrel during each shot, and you get 3000 rounds of accurate barrel life, how much actual firing time does the barrel deliver before it loses accuracy? That’s simple math: 3000 x .002 seconds = 6 seconds.

Stopwatch barrel lifeGone in Six Seconds. Want to Cry Now?
Six seconds. That’s how long your barrel actually functions (in terms of bullet-in-barrel shot time) before it “goes south”. Yes, we know some barrels last longer than 3000 rounds. On the other hand, plenty of .243 Win and 6.5-284 barrels lose accuracy in 1500 rounds or less. If your barrel loses accuracy at the 1500-round mark, then it only worked for three seconds! Of course, if you are shooting a “long-lived” .308 Win that goes 5000 rounds before losing accuracy, then you get a whopping TEN seconds of barrel life. Anyway you look at it, a rifle barrel has very little longevity, when you consider actual firing time.

People already lament the high cost of replacing barrels. Now that you know how short-lived barrels really are, you can complain even louder. Of course our analysis does give you even more of an excuse to buy a nice new Bartlein, Krieger, Shilen etc. barrel for that fine rifle of yours.

Handgun Marksmanship — Diagnosing Pistol Accuracy Problems

NSSF Chris Cheng Pistol Accuracy Handgun Shooting Skills

Over the past year, this was one of the TOP TEN most-read Daily Bulletin articles. We are reprising it today for readers who may have missed it the first time around…

When shooting pistols do your shots normally land smack dab in the middle of the target? If not, you may have some technique problems that are causing your shots to move off center. Top Shot Champion Chris Cheng has produced a good video for the National Shooting Sports Foundation (NSSF) that helps handgunners diagnose accuracy issues. By shooting 3-shot groups and looking at the pattern and location of the shots, you can see what you’re doing wrong (or right). Here are some examples. Note, this process works best for shooters whose shots fall typically in one target zone. If your shots are all over the target, your form is inconsistent and problems will be harder to diagnose.

1. Low Left — Jerking Trigger: Here we see three (3) shots at the 7 O’clock position. This shows that the shooter is jerking the trigger, meaning that the shooter is pulling the trigger too quickly and therefore forcing the barrel to drop when breaking the shot. This is a very common problem, particularly with novices who are reacting to the noise/recoil of the pistol.

NSSF Chris Cheng Pistol Accuracy Handgun Shooting Skills

2. 9 O’Clock — Too Little Trigger Finger: If we see three (3) shots at the 9 O’clock position, what this can be indicative of too little trigger finger on the trigger. And therefore with every shot, the shots are getting pushed to the left. Try moving your trigger finger on to the pad of your index finger. Also try dry firing drills.

NSSF Chris Cheng Pistol Accuracy Handgun Shooting Skills

3. High Left — Anticipating Recoil: In this next example, we see three shots around the 11 O’clock position. What could be happening here is that the shooter is anticipating the recoil, and is actually lifting the gun up when he shoots. We recommend slowing down, working on your breathing, and, again, do dry-firing drills.

NSSF Chris Cheng Pistol Accuracy Handgun Shooting Skills

4. 3 O’Clock — Too Much Trigger Finger: Finally, if you see three (3) shots at the 3 O’clock position, this can indicate that there is too much trigger finger on the trigger. Therefore when the shot breaks the shooter is pulling each shot to the right. Note: Each of these descriptions is for a RIGHT-handed shooter. If you are a left-handed shooter you’ll want to reverse those descriptions.

Hand-Loading for Semi-Auto Service Rifles — Six Key Rules

Reloading for Service Rifles
SFC Lance Dement as featured in CMP’s First Shot Online.

The U.S. Army Marksmanship Unit (USAMU) has published a great series of reloading “how-to” articles on its Facebook Page. This post covers key factors to consider when loading ammunition for Match Rifles and Service Rifles, with a particular focus on self-loading “gas guns”. Visit the USAMU Facebook Page each Wednesday for other, helpful “Handloading Hump-Day” tips.

We offer some “cardinal rules” to help new gas-gun handloaders with safety and efficiency. These address both Match Rifle and Service Rifle versions of the AR15, M1 Garand, M1A, and M110. However, they can also improve safe reloading for many other auto-loaders such as M1 Carbines, FALs, SIGs, etc. The author distilled these principles many years ago to help focus on the essential aspects of these rifles.

RULE ONE: Service Rifles Are Not Benchrest Rifles
Gas-guns require a relatively loose fit between ammunition and chamber (vs. bolt actions) for safe, smooth operation. Many techniques, such as neck sizing and keeping cartridge headspace quite tight, are popular in the extreme bolt gun accuracy realm. However, they are of little value with Service Rifles, and some could even be hazardous. Before adopting a specialized technique, seriously consider whether it is appropriate and beneficial in a gas-gun.

RULE TWO: Never Compromise Safety to Obtain Accuracy
Example: If choosing a brand of great, but ultra-sensitive match primers offers possibly better accuracy at the risk of slam-fires in your design of rifle, don’t do it! You are issued exactly two eyes and ten fingers (best-case scenario). Risking them trying to squeeze 0.25 MOA better accuracy out of an M1A, etc. simply isn’t worth it.

Reloading for Service Rifles

RULE THREE: Tailor the Precision to Your Individual Skill and Your Rifle’s Potential
This has been addressed here before, but bears repeating for newcomers. If you are struggling to break out of the Marksman Class, or using a CMP M1 “As-Issued,” then laboriously turning the necks of your 600-yard brass is a waste of time. Your scores will improve much faster by practicing or dry-firing. On the other hand, if the reigning champions anxiously check your scores each time you fire an event, a little neck-turning might not be so far-fetched.

Verifying Load Improvements — Accuracy hand-loading involves a wide variety of techniques, ranging from basic to rather precise. Carefully select those which offer a good return on investment for your time and labor. In doubt? Do a classic pilot study. Prepare ammo for at least three or four ten-shot groups with your new technique, vs. the same with your standard ammo. Then, pick a calm day and test the ammo as carefully as possible at its full distance (e.g. 200, 300, or 600 yards) to verify a significant improvement. A little testing can save much labor!

RULE FOUR: Be Your Own Efficiency Expert
Serious Service Rifle shooters generally think of ammunition in terms of thousands of rounds, not “boxes”, or even “hundreds”. Analyze, and WRITE DOWN each step in your reloading process. Count the number of times each case is handled. Then, see if any operations can be dropped or changed without reducing safety or accuracy. Eliminating just two operations saves 2000 steps per 1000 rounds loaded. Conversely, carefully consider any measurable benefits before adding a step to your routine.

RULE FIVE: In Searching for Greater Accuracy with Efficiency, Look for System Changes
For example, instead of marking your 300-yard rounds individually to differentiate them from your 200-yard ammo, would a simple change in primers work? If accuracy is maintained, using brass-colored primers for 200 and silver for 300 provides an indelible indicator and eliminates a step! Similarly, rather than spending hours selecting GI surplus brass for weight and neck uniformity, consider splurging on some known, high-quality imported match brass for your 600-yard loads. Results should be excellent, time is saved, and given limited shooting at 600 yards, brass life should be long.

RULE SIX: Check All Your Primers Before Packaging Your Loaded Ammo
This seems simple and even intuitive. However, many slam-fires (which were much more common when M1s and M1As were the standard) are due, at least in part, to “high” primers. Primers should be seated below flush with the case head. The USAMU has addressed this at length in a previous column, but each round should be checked for properly-seated primers before they are packaged for use.

Brownells Video Shows How to Cut Chamfer on Barrel Crown

brownells crown muzzle barrel bullet accuracy gunsmithing

This video from Brownells talks about a the crown of a barrel and how the crown’s condition affects accuracy. As the bullet leaves the barrel of the gun, the shape, alignment and the condition of the crown can affect the accuracy of your shot. A proper crown is essential to ensure that the bullet leaves the barrel correctly and that the propellant gasses behind the bullet are distributed evenly on firing. A square crown without burrs and a smooth transition will normally ensure consistency from shot to shot. By contrast, a damaged crown can cause unpredictable flyers that open your group. That’s why it’s important to have perfect crowns on all your barrels.

The video explains the different types of crowns that can be used. In addition, the video shows how you can chamfer your muzzle in a home shop. If you use a properly-sized pilot, cutting a shallow chamfer is something that most guys with some mechanical skill can handle. Just be sure to use lubricant, flush chips, and don’t rush the job. Cutting the barrel is another matter. At the 1:20 mark the video shows how to use a hack-saw to remove a damaged muzzle section. While this may be fine for an inexpensive rifle that needs a “quick fix”, we do NOT recommend using a hack-saw with a vise for a competition barrel. The reason is that it is too easy for a novice to produce a cut that is not square. We suggest letting a professional gunsmith cut and crown your competition barrels.

Accuracy Vs. Precision — They Are Not the Same Thing

Applied Ballistics Accuracy Precision
This image is from Modern Advancements in Long Range Shooting, Volume 2.

The next time a shooter comes up to you at the range, and says: “My rifle shoots one-third MOA all day long”, challenge him to put a first-round hit on a 1/2 MOA plate at 1000 yards. There’s a difference between shooting small groups at close range (Precision) and “on-target” Accuracy at long range.

Article by Applied Ballistics, LLC
Just how much better is a 0.5 MOA rifle vs. a 1 MOA rifle? Is it worth chasing quarter-MOA if you have half-MOA rifle? This is an important question. If you look across Facebook you will find scores of shooters posting 1/3-MOA or 1/4-MOA shot groups [usually at 100 yards]. Some of those guys are spending countless hours trying to chase that golden quarter-MOA group.

Don’t take this statement the wrong way, having a good, consistent rifle is a key to success. But accuracy is extremely important to long range shooting. Having a precision (0.5 MOA) rifle, but not having put the time in to practice accuracy (hitting a 0.5 MOA plate first shot at 1000 yards) is counter-productive. [Editor: By this, we mean that you can have a rifle capable of shooting small groups at 100 yards, but you won’t see that gun’s full potential unless you can practice and perfect the skills of long-range shooting. Successful long range shooting demands more than precision alone.]

What if, your goal was to produce 5-shot, sub-half-MOA groups at 1000 yards instead of 100 yards? Think about how much more you would be including in the learning process, especially that all-important factor: managing the wind! Here is a good article that talks about Precision vs. Accuracy: Hitting Targets at Long Range.

This is not intended to say that precision is not important; rather it is intended to show that balance is important. You can use WEZ to do your own studies on this very subject, and it might be surprising to the shooter just how much you don’t gain by chasing precision over accuracy. Two books which cover this subject really well are Accuracy and Precision for Long Range Shooting and Modern Advancements in Long Range Shooting Vol 2.

Here’s a stunning combination of Precision (small group) WITH accuracy (centered on target). Yep that’s ten shots at 1000 yards, all in the middle of the target:
Scott Nix Dasher Record

Video Demonstrates Amazing 1000-Yard Accuracy AND Precision

Watch the video. You can see the group form up, shot by shot. It’s pretty amazing. Scott’s first shot (at the 45-second mark of the video) was right in the X-Ring, and four of Scott’s first five shots were Xs. That’s drilling them!

Comments

“Accuracy with precision is the route for me. It is not an either/or game. If I have a precision rifle (0.25 MOA or less) and I practice to be accurate, then high scores will be the result — Jim Borden

“I would agree for PRS, hunting, and to a certain extent F-Class. However, for 1000-yard IBS benchrest competition, 0.5 MOA groups in good conditions will almost always loose the relay.” — James B

“Another thought is that [at 1000 yards] a 1 MOA gun with single-digit standard deviations [may] out shoot a 0.5 MOA rifle with standard deviations of 20+ fps.” — Beard Owens

“Both… you need both: Accuracy AND Precision. I competed in varmint matches — we shot small silhouettes at 600 yards. I started with a factory .260 Rem rifle that was 0.8 MOA on a good day. I typically hit 8-9 of 20 targets, but rarely nailed the small chickens — which had a hit zone just 4″ in diameter. I then started using a semi-custom 6mmBR rifle that could reliably deliver 1/4 MOA at 100 yards (honest). My hit count on the silhouettes zoomed to 15-18, and suddenly the chickens were going down. In that game — small targets at 600 yards — there was no substitute for precision.” — Paul McM

How Much Accuracy is Enough — What Works for Your Discipline?

Jim See Elite Accuracy
This impressive 15-round group was shot by Jim See of Elite Accuracy.

Different shooting disciplines demand different levels of precision/accuracy. In the rapid-fire 3-Gun game, you could probably “clean” most stages with a 2-MOA rifle. By contrast, in the short-range group benchrest game, to compete with the best, you’ll need a rifle that shoots in the “ones” (i.e. 0.1-0.19 MOA) in perfect conditions. In 1000-yard F-Class competition, the top shooters want a rifle that will hold one-third-MOA of vertical at that distance.

What is your standard of accuracy? How good is “good enough”. Jim See, a skilled gunsmith and successful PRS competitor, recently answered that question for his tactical discipline. For the kind of matches Jim shoots, he likes to have a rifle that will hold half-MOA for five (5) shots, 3/4-MOA for 15 shots, and 1 MOA for twenty shots. Remarkably, Jim’s rifle can do that with factory ammo. Above is an impressive 15-shot group shot with .260 Remington Federal Premium Ammo.

Jim See Elite Accuracy

“I say it all the time, my loads need to print 5 under 1/2″, 10 under 3/4″, and 20 under 1″. It’s simple, if a hot barrel will keep 20 rounds fired in succession under my standard it will be a good barrel and load for Precision Match Shooting. Federal Premium Gold Metal Match .260 with Sierra bullets made the cut for me today. 15 consecutive shots under 3/4 MOA.” –Jim See

It’s said that you “can never have too much accuracy”, but there are acceptable standards for each discipline, and they’re not the same. A 100/200 yard Benchrest shooter will be sorely disappointed with a rifle/ammo set-up that can only deliver half-MOA. On the other hand, a PRS competitor like Jim See can achieve great success with a lesser degree of precision. This means you can save time and money. You can run your barrels longer between cleanings, and you don’t have to go “full OCD” when loading your ammo. The PRS shooter does not need to weigh-sort primers, or load powder to single-kernel standards. Proof is the performance. Jim See recently took third place at the Spearpoint Shootout, and he has been a podium finisher at other events. Learn more about Jim’s gunsmithing and training operations at EliteAccuracy.com.

Download This Load Development Target

Jim’s target seemed a bit familiar. AccurateShooter.com created this Diamond and Dot Target a few years back. On each aiming point, there are high-contrast black horizontal and vertical lines for aligning your cross-hairs. The gray circle lets you see the bullet impacts above, without obliterating the red diamond, which is quite useful for precise aiming (we put fine cross-hairs on the points of the diamond). This target sheet includes data entry tables below each of the three aim points. There are many other free targets out there, but this format is very popular. We’re pleased to see Jim using it.

Dime-Sized Groups All Day Long — Yeah, Right…

Dime size meme humor joke accuracy

We’ve all encountered those boastful guys at the range — you know, the ones who say their factory rifle will shoot “dime-sized groups all day long.” Well maybe they were actually telling the truth — it all depends on the size of the ten-cent piece. With the huge dime shown above, we think we could shoot “dime-sized groups all day long” — even with a pistol. After seeing this, one reader commented: “That’s great. So this means my groups are only around Quarter-sized!”

Credit Forum member DKhunt14 who started a thread with this humorous image in our Shooters’ Forum. Other Forum members gave examples of similar accuracy claims they’ve heard:

I ran into a local tactical guru a few years ago that topped any story I’ve ever heard yet. He claimed he could shoot a quarter-inch group every time at 300 yards — like no problem whatsoever. — IMMike

I had a guy tell me he dropped a doe at 420 yards with a M1 carbine, open sights. Never took a step. I’ll bet he also shot those dime-sized groups!– DJ Porter

Seems like we could substitute 1000-yard prairie dog (other small varmint) hits for dime-sized groups. They both happen “all day long”. — Dsandfort

Many folks come into my shop… and feel compelled to regale me with their life history with firearms. Head-shooting squirrels at 100 yards with a .22 short and iron sights, deer dropped at 500 yards with a .35 Rem, ground hogs taken with one shot across vast distances, etc. — and it would appear that every former SEAL, Marine or SF sniper lives in the general area. My Dad used to tell me that sometimes you just have to smile and nod a lot. Not always, but a lot.

I’m not a huge fan of Bass Pro Shop, but I DO appreciate Bass Pro’s motto: “Welcome hunters, fishermen and other liars.” Human nature can be so entertaining. — JLT

GET Your Own Giant DIME

By the way, if you want your own jumbo dime, Amazon.com offers 3″-diameter Roosevelt dimes for about five bucks. These would be good for range accuracy challenges. You could tell a buddy you can “put five shots on a dime at 200 yards”. Then whip out this slightly oversize 3-incher and see his face.

These could also serve as “gag prizes” at club shooting matches — giveaways for folks who want to say they shot a group at 200 or 300 yards that could be “covered with a dime” … a 3″ dime that is!

Six Tips for Better Results at Club Matches

Every summer weekend, there are probably 400 or more club “fun matches” conducted around the country. One of the good things about these club shoots is that you don’t have to spend a fortune on equipment to have fun. But we’ve seen that many club shooters handicap themselves with a few common equipment oversights or lack of attention to detail while reloading. Here are SIX TIPS that can help you avoid these common mistakes, and build more accurate ammo for your club matches.

Benchrest rear bag1. Align Front Rest and Rear Bags. We see many shooters whose rear bag is angled left or right relative to the bore axis. This can happen when you rush your set-up. But even if you set the gun up carefully, the rear bag can twist due to recoil or the way your arm contacts the bag. After every shot, make sure your rear bag is aligned properly (this is especially important for bag squeezers who may actually pull the bag out of alignment as they squeeze).

Forum member ArtB adds: “To align my front rest and rear bag with the target, I use an old golf club shaft. I run it from my front rest stop through a line that crosses over my speed screw and into the slot between the two ears. I stand behind that set-up and make sure I see a straight line pointing at the target. I also have a piece of tape that I’ve placed on the golf shaft that indicates how far the back end of the rear bag should be placed from the front rest stop. Don’t have an old golf shaft? Go to Home Depot and buy an inexpensive piece of wood dowel.”

2. Avoid Contact Interference. We see three common kinds of contact or mechanical interference that can really hurt accuracy. First, if your stock has front and/or rear sling swivels make sure these do NOT contact the front or rear bags at any point of the gun’s travel. When a sling swivel digs into the front bag that can cause a shot to pop high or low. To avoid this, reposition the rifle so the swivels don’t contact the bags or simply remove the swivels before your match. Second, watch out for the rear of the stock grip area. Make sure this is not resting on the bag as you fire and that it can’t come back to contact the bag during recoil. That lip or edge at the bottom of the grip can cause problems when it contacts the rear bag. Third, watch out for the stud or arm on the front rest that limits forward stock travel. With some rests this is high enough that it can actually contact the barrel. We encountered one shooter recently who was complaining about “vertical flyers” during his match. It turns out his barrel was actually hitting the front stop! With most front rests you can either lower the stop or twist the arm to the left or right so it won’t contact the barrel.

3. Weigh Your Charges — Every One. This may sound obvious, but many folks still rely on a powder measure. Yes we know that most short-range BR shooters throw their charges without weighing, but if you’re going to pre-load for a club match there is no reason NOT to weigh your charges. You may be surprised at how inconsistent your powder measure actually is. One of our testers was recently throwing H4198 charges from a Harrell’s measure for his 30BR. Each charge was then weighed twice with a Denver Instrument lab scale. Our tester found that thrown charges varied by up to 0.7 grains! And that’s with a premium measure.

4. Measure Your Loaded Ammo — After Bullet Seating. Even if you’ve checked your brass and bullets prior to assembling your ammo, we recommend that you weigh your loaded rounds and measure them from base of case to bullet ogive using a comparator. If you find a round that is “way off” in weight or more than .005″ off your intended base to ogive length, set it aside and use that round for a fouler. (Note: if the weight is off by more than 6 or 7 grains you may want to disassemble the round and check your powder charge.) With premium, pre-sorted bullets, we’ve found that we can keep 95% of loaded rounds within a range of .002″, measuring from base (of case) to ogive. Now, with some lots of bullets, you just can’t keep things within .002″, but you should still measure each loaded match round to ensure you don’t have some cases that are way too short or way too long.

Scope Ring5. Check Your Fasteners. Before a match you need to double-check your scope rings or iron sight mounts to ensure everything is tight. Likewise, you should check the tension on the screws/bolts that hold the action in place. Even with a low-recoiling rimfire rifle, action screws or scope rings can come loose during normal shooting.

6. Make a Checklist and Pack the Night Before. Ever drive 50 miles to a match then discover you have the wrong ammo or that you forgot your bolt? Well, mistakes like that happen to the best of us. You can avoid these oversights (and reduce stress at matches) by making a checklist of all the stuff you need. Organize your firearms, range kit, ammo box, and shooting accessories the night before the match. And, like a good Boy Scout, “be prepared”. Bring a jacket and hat if it might be cold. If you have windflags, bring them (even if you’re not sure the rules allow them). Bring spare batteries, and it’s wise to bring a spare rifle and ammo for it. If you have just one gun, a simple mechanical breakdown (such as a broken firing pin) can ruin your whole weekend.

What Makes an AR Accurate — Whitley Offers Answers

AR-X AR15 Upper

In our Shooters’ Forum, one member recently asked: “What makes an AR accurate? What parts on an AR can really affect accuracy — such as free-floating handguards, barrels, bolts, bolt carriers?” He wanted an honest, well-informed answer, not just sales pitches. Robert Whitley posted a very comprehensive answer to this question, based on his experience building and testing dozens of AR-platform rifles. Robert runs AR-X Enterprises, which produces match-grade uppers for High Power competitors, tactical shooters, and varminters.

AR-X AR15 Upper

Building an Accurate AR — What is Most Important

by Robert Whitley
There are a lot of things that can be done to an AR to enhance consistent accuracy, and I use the words “consistent accuracy” because consistency is a part of it (i.e. plenty of guns will give a couple great 5-shot groups, but won’t do a very good 10- or 20-shot groups, and some guns will shoot great one day and not so good on others).

Here are 14 key things we think are important to accuracy.

1. Great Barrel: You’ll want a premium match-grade barrel, well-machined with a good crown and a match-type chambering, true to the bore and well cut. The extension threads must also be cut true to the bore, with everything true and in proper alignment.

2. Rigid Upper: A rigid, heavy-walled upper receiver aids accuracy. The typical AR upper receiver was made for a lightweight carry rifle and they stripped all the metal they could off it to make it light to carry (which is advantageous for the military). The net result are upper receivers that are so thin you can flex them with your bare hands. These flexible uppers are “strong enough” for general use, but they are not ideal for accuracy. Accuracy improves with a more rigid upper receiver.

Using Barrel With 100,000+ Rounds, Joe Sets New ARA Record

.22 LR Eley Rimfire benchrest joe friedrich ARA target
Click to zoom image.

Some folks think you need a new (or nearly-new) barrel to win a benchrest match. That may be true in the centerfire game, but in the world of rimfire benchrest, things are different. Good barrels can remain accurate for a long, long time. That was demonstrated by our friend Joe Friedrich who recently set a new ARA 4-target Aggregate record. Joe was shooting his trusty old “Sweet Pea” rifle with a very well-worn barrel. In fact, Joe’s record-setting Benchmark barrel has logged well over 100,000 rounds. That’s right, a barrel with over 100K rounds shot the best 4-target ARA Agg ever. Will wonders never cease…

That’s Precision: 10 Shots in 0.29 MOA — with a Pistol!

Report by Boyd Allen
This pistol belongs to Dan Lutke, a Bay Area benchrest shooter who publishes the results for the Visalia matches to the competitors and the NBRSA. He has been an enthusiastic competitor for an number of years, at various ranges, notably Visalia and Sacramento. The action is a Remington XP-100, to which a Kelbly 2 oz. trigger has been fitted. On top is an old Japanese-made Tasco 36X scope (these were actually pretty darn good). The Hart barrel (a cast-off from Dan’s Unlimited rail gun) was shortened and re-chambered for the 6x45mm, a wildcat made by necking-up the .223 Remington parent case. The custom stock/chassis was CNC-machined by Joe Updike from 6061 Billet Aluminum to fit the XP-100 action and mount a target-style AR grip with bottom hand rest. The gun was bedded and assembled by Mel Iwatsubu. In his XP-100 pistol, Dan shoots 65gr custom boat-tails with Benchmark powder.

Bill Goad Concentricity Gauge Works by Impact

Over the years, many different concentricity tools have been on the market. Various approaches have been taken to straightening rounds that exhibit poor concentricity. With extreme examples of excessive run-out, the bullet is is visibly crooked in the neck with the bullet tip clearly off-center. That’s never a good thing. Straight ammo shoots better.

Bill  Goad Extreme Precision Concentricity  Gauge Tool Video

Straighten-Up and Fly Right
If you could straighten up crooked rounds, accuracy should be improved. In the past, some tools promised more than they delivered. But now Bill Goad, a record-setting benchrest shooter, has invented a new tool that improves concentricity via an impact or “jarring” method. A vertical rod with a curved face mates with the case-neck. You spin the case to find the “high spot” of max eccentricity. Then just tap the rod a couple of times and the neck comes back onto centerline. You can then confirm the concentricity improvement with the dial indicator. Watch the video to see how this is done. Pay particular attention to times 01:25 to 01:45. The case starts at .004″ run-out (01:32). After correction (01:40) the neck shows less than .001″ (one-thousandth) run-out.

Benchrest ace Bill Goad demonstrates his innovative Fli-Right Concentricity gauge tool. It works differently than other concentricity enhancers on the market.

Bill Goad knows something about accuracy. He shot a 10-target 100/200 benchrest Combined Aggregate of 0.178″ (see video at 00:15-00:35). Bill Goad’s tool offers advantages over systems that clamp a cartridge at both ends and try to bend the case or tilt the bullet without straightening the neck. Goad’s new Fli-Right tool is available now from PremierAccuracy.com.

IBS Kicks Off 2013 with Bridgeville 600-Yard Matches

Match Report by Mike Wallace for the IBS, with photos by Hillary Martinez and Dean Breeden. This is the first in a series of in-depth match reports published jointly by the IBS and Accurateshooter.com.

Bridgeville 600 yard benchrest match

The Bridgeville Rifle and Pistol Club (Bridgeville, DE) held 600-yard IBS matches on March 16 and 17 — a separate match on each day. These two matches were the final competitions counting towards Bridgeville’s 600-yard Shooter of the Year honors. Turn-out was strong, with 21 Light Gun (LG), 17 Heavy Gun (HG), and 1 Factory Class competitors. On Day 1, weather (for Bridgeville) was good, with temperatures as high as 54° F, winds less than gale force, periods of overcast and bright sun. On the 17th the shooters braved more challenging conditions. Temps ranged from the low 30s to as high as 40 degrees, with more wind than the previous day and snow flurries in the afternoon.

Bridgeville 600 yard benchrest matchCompetition is very keen at Bridgeville. Richard Timmons, Match Director, said, “It can be challenging….it can cause you to talk to yourself!” Rookies and those interested in taking up the sport are gladly welcomed and mentored. When asked his advice for new shooters in the sport, Richard said, “Factory Class is the best place to start for beginning shooters. There are some good factory guns out there that will shoot 600 yards.”

The Bridgeville matches showcased a bright, young talent. 12-year-old Kevin Donalds Jr., the youngest competitor at the two-day event, is already a shooter to be reckoned with — Kevin placed 2nd in Light Gun Group (2.5343) at the March 17th Match. Woe unto many of us later because Kevin plans on staying in the sport a long time!

Shooting at Bridgeville is Fun and Challenging
Bridgeville 600 yard benchrest matchDewey Hancock is a rookie in his second year in the sport and is making a mark as you can see from match results and Shooter of the Year standings at Bridgeville R&P Club. He advises, “Good bench handling, good equipment, a good gunsmith, and good loading practice — these things will make you shoot with the good guys. You want to stay consistent in this game and that will eventually get you some wins.” When asked who his biggest competitor is, he smiled and said, “The wind!”, but then slipped in Roy Hunter’s name for 600 yards and Dean Breeden for the short range game. Dewey also stated what many of us in the sport know – “It is fun and the whole family can do it.”

Craig Rowe, in the sport for seven years shooting 600 yards and Score, said: “Bridgeville is a great place to shoot – great people – great food – and lots of great competition.” Craig cautions: “Don’t think you’re going to come here, walk in and steal the show, because there are a lot of good shooters.”

New Berger 105gr 6mm Hybrid Bullets Perform Well

105gr Hybrid Tests Demonstrate Excellent Accuracy and Consistency
By Robert Whitley
After the initial Daily Bulletin Report on the new Berger 6mm 105gr Hybrids, I did some accuracy and consistency field testing with these new bullets. They shot so well, I thought an update was in order. My 100-yard testing has revealed much about these new bullets — all of it good so far. The test rifle was a MAK Tube Gun with a trued Rem 700 action (glued in), with a 6mm Brux 30″, 1:8″-twist barrel chambered with a no-neck-turn 6mm BRX chamber (1.563″ max case and .120″ free bore). The 6mm 105gr Hybrids fit and work well in this 6 BRX chamber configuration. (CLICK HERE to view a print of the reamer I used for the 6 BRX chamber.)

Berger 6mm 105 grain Hybrid bullet

Hybrids Show Excellent Accuracy in Prone Tests (with Sling)
As some may know, I am predominantly a prone shooter and do most of my load testing prone with a sling. I chose to do the same with these Hybrids, to see how they would perform when fired as they would be in a prone match. In this case, shooting prone with sling, I shot four 10-shot groups (two 10-shot groups in each of two range session). All four groups were right around .5 MOA (i.e. each group about .750″ edge-to-edge, minus a bullet diameter of .243″ = .507″). The new Berger 6mm 105gr Hybrid bullets had no problems doing this. The groups shot were also consistent with the best groups I have been able to shoot in the past with the Berger 108gr BT bullets and the Berger 105gr VLD bullets, and I consider both of those bullets to be excellent and accurate. There is no question in my mind that these new Hybrid bullets are accurate, and the consistency is there! Check out my test targets below.

The two 10-shot targets above were shot at 100 yards on September 30th, prone with sling. The 6 BRX load was: Berger 6mm 105gr Hybrids, Lapua brass, 32.0 grains N140, Federal 205M-AR primers, .020″ jump. Note: If you put the targets over each other the groups line up perfectly.

These two 10-shot targets (above) were shot at 100 yards on September 23, prone with sling. The 6 BRX load was: Berger 6mm 105gr Hybrids, Lapua brass, 31.0 grains H4895, Federal 205M-AR primers, .020″ jump. When I can shoot 20 Xs in a row (as I did with these two targets) the rifle is really shooting well.

Accuracy needs to be coupled with consistency, especially when running longer strings of fire or in matches demanding a larger number of hits on the target. I am pleased to report that I have found the Berger 105gr Hybrid bullets to be consistently accurate bullets (i.e. there were no anomalies or fliers, they just keep going where you pointed the rifle). At each of the last two range sessions I shot back to back 10-shot groups with no break between the two (i.e. 20 shots in a row and only switching to the next target after 10 shots). Not only did the individual 10-shot groups stay tight, but if you hold each first target over the second target, the groups are right on top of one another. This is what I look for in terms of consistency — that I can keep shooting, and the bullets keep going right into the group, with no odd fliers.

105gr Hybrid Bearing Surface and Optimum Free Bore
Shooters may wonder how the new 6mm 105gr Hybrids function with the existing freebores on chambers set up for current Berger 105gr VLDs and Berger 108gr BT bullets. Based on the investigation and measuring of various chambers, here are some general guidelines:

1. For a chamber with a 1.5° throat angle, and the bullets touching the lands, the Berger 105gr Hybrid bullets sit up in the neck a little further than both the current production Berger 105 VLD Target bullets and the Berger 108gr BT bullets.

2. Based on basic measuring and testing, for the junction of the boat tail and bearing surface of a 6mm 105gr Hybrid bullet to be in the same spot as other bullets, the 105 Hybrid (Lot #3079) would need about .020″ – .025″ less freebore than recent production Berger 105gr Target VLD bullets (Lot #3220) and about .030″ – .035″ less freebore than recent Berger 108gr Target BT bullets (lot #2791).

3. Since the Hybrids are designed to work both in the lands and jumped away from the lands, some extra freebore may not be a bad thing. In truth, the 105 Hybrid bullets should work well and fit well in various 6mm chamberings (such as 6 BRX, 6 Dasher, 6mmAR etc.) which have been optimized for the previous generation, non-Hybrid 6mm Berger 105s and 108s.

Here’s a sample from our chapter on the Joys of Abrasives: “We all learned as kids that shiny is good. Well it is. And more shiny is even better. Why settle for a bore that has anything less than a mirror finish? Just do a quick high-pressure bead-blast down your bore, followed by few thousand strokes with JB, and your bore will be perfectly slick and shiny. And you won’t have to waste any more time with those annoying lands and grooves that trap carbon and copper. They’re gone for good! Polish your bore to a mirror finish for the ultimate in barrel cleanliness.”
