NRA publication Shooting Sports USA (SSUSA) has thousands of articles online, all free for the reading. Many of these stories have been written by top competitors, including National and Olympic Champions. You will find SSUSA articles spotlighted every week on the NRA Competitive Shooting Facebook page. We recommend you bookmark that page as a valuable resource. Here are four notable SSUSA articles that have been featured on Facebook this month. Go to SSUSA.org to see even more current articles, with new content every day.
Here is an insightful, fairly lengthy 1850-word article about the phenomenon we call mirage. The article explains how and why mirage appears, how it can best be monitored, and how mirage can indicate both wind velocity and direction. Top competitors follow the adage “Mirage is your friend”, because mirage can often be the most important indicator of wind variables — sometimes even more important than wind flags. “The mirage is more sensitive than the flags since it has less inertia and momentum”, wrote Desmond T. Burke, in his book, Canadian Bisley Shooting, an Art and a Science.
Well worth reading, this SSUSA article talks about the properties of mirage. Here is a sample:
“Mirage — can make all the difference between a shot landing squarely in the X-ring or being victimized by an undetected downrange breeze. The true power of mirage is found in its ability to betray the subtlest of breezes downrange. Its fluid movement… can not only provide wind direction, but speed as well.
Typically, the ability to detect mirage is maximized on warm, sunny and sultry days. Expect mirage to be most pronounced in mid-morning or early afternoon, although it ignores these rules with regularity[.]
Mirage is extremely powerful at identifying winds of less than 12 mph, particularly those gentle breezes subtle enough to not even bother moving the flags.
When there is no wind, or a gentle head or tail wind, mirage will appear to be ‘bubbling’ directly up from the ground. Many call this ‘boiling’, and it is probably the easiest of all to detect.
As a general rule of thumb, when wind speed increases, overall height of the waves produced by the mirage is reduced. Large peaks and valleys in the waves mean that particular mirage is being driven by a very slight breeze. Conversely, crest size is reduced with wind speed, making it harder and harder to detect, until the mirage disappears entirely at somewhere around 12 miles per hour. In other words, the taller mirage’s waves appear, the slower the breeze.”
Authored by the late Glen Zediker, this article covers barrel break-in procedures. It is particularly useful for dealing with factory barrels. We CAUTION readers — with outstanding, hand-lapped custom barrels from top barrel-makers, you may want to do very little break-in — clean sparingly and keep barrel heat low. Do NOT use abrasives aggressively. On our Krieger and Brux barrels, we simply wet-patched every 2-3 rounds for 20 rounds and the barrels shot superbly from the start with minimal fouling. But for factory barrels, a moderate break-in process may prove beneficial.
Zediker explains: “Lesser, lower-cost barrels are going to have more pronounced … imperfections within the bore[.] These imperfections are largely tool marks resulting from the drilling and rifling processes. And if it’s a semi-automatic, like an AR-15, there might be a burr where the gas port was drilled. The goal of break-in is to knock down these imperfections, thereby smoothing the interior surface.”
As one who has experienced a cartridge case-head blow-out with a 9mm pistol, this Editor is very conscious of the risks involved and the damage a blow-out can do to the pistol, to the magazine, and (worst of all) to the shooter. Even with new brass, the possibility of a case failure is always present. And even if the case remains intact, we’ve seen primer failures that create a dangerous jet back towards the pistol shooter. That’s why shooters should always employ protective eyewear whenever they shoot.
We love our wheelguns, but there’s no doubt that forcing cone damage can occur, particularly with hot loads and if your cylinder-to-barrel gap is excessive. This article explains how to inspect your revolvers, and how to mitigate the likelihood of forcing cone damage. The article also explains how to clean your revolvers properly. This is very important to avoid build-up of lead and powder residues.
Soon after Lapua released the 6.5×47 cartridge, wildcatters recognized the potential of a necked-down 6mm version of the case. The 6-6.5×47 has emerged as a great, do-it-all cartridge that performs well in High Power competition, 600- and 1000-yard benchrest, and PRS tactical matches. But the 6-6.5×47 is not just for paper-punching. An efficient cartridge with great inherent accuracy, the 6-6.5×47 can be an excellent, flat-shooting, long-range varmint round. Here we feature Stan Stewart’s BAT-actioned 6-6.5×47 varminter. Fitted with a Krieger 1:10″ barrel, Stan’s rifle excels with a wide variety of varmint bullets. Whether driving 70-grainers at 3700 fps, or pushing the Berger 88gr High-BC FB bullet at 3400 fps, this 6-6.5×47 delivers half-MOA (or better) accuracy, in a well-balanced, easy-handling rifle.
The 6-6.5×47 for Precision Long-Range Varminting
The rifle carries a 12-42x56mm Nightforce NSX in Nightforce rings “hand-lapped for optimal fit/alignment”.
‘Seller’s Remorse’ Spurs 6mm Project Report by Stan Stewart
After selling my 6mm Remington Ackley Improved a couple of years ago and wishing I hadn’t, I begun to think about a new custom rifle for work on Prairie Dog towns and New York wood chucks at 600+ yards. I have a .223 AR and 22-250 for medium ranges but I missed my 6mm AI for long-range work so I started asking questions.
The 22-250 is a fine chambering, but it is hard on barrels, and I think the 6mms may have an accuracy edge out past 400 yards. Also, shooters today enjoy a vast collection of really great 6mm bullets. Barrel life and bullet options were two main reasons I decided to build a 6mm rather than another .224-caliber gun. But the question remained… what 6mm chambering to choose?
I started doing serious research on the 6-6.5×47. I received a lot of good advice from AccurateShooter.com and other websites on the pros and cons. I also talked to gunsmiths — quite a few recommended the new cartridge as well. Some of the cartridge attributes I liked was the small rifle primer, enough case capacity to efficiently reach 3700 fps with a 70gr bullet and 3400 fps with an 85-grainer without being terribly over-bore. Most important was the 6-6.5×47’s reputation for inherent accuracy without being finicky like my 6mm AI. So, having chosen my cartridge, I started asking for gunsmith recommendations. Again the folks on the AccurateShooter.com Forum were very helpful. After many conversations I settled on Dave Bruno in Dayton, Pennsylvania. He was a good choice.
Putting Together the New Rig with Premium Components
From the get-go, I knew I wanted a BAT action and Krieger barrel. BAT Machine and Krieger Barrels enjoy a great reputation in the shooting industry. BATs are beautifully-machined, smooth, and strong. Krieger cut-rifled barrels are known for dependable accuracy and long barrel life. While many 6-6.5×47 shooters choose an 8-twist barrel to shoot the 100-108gr bullets, I would be using smaller, varmint-weight bullets, so I selected a 1:10″ twist Krieger. This would allow me to shoot bullets from 60 grains up to 90 grains. Dave chambered the barrel with a .269″ neck and fluted the barrel to save weight. I also had Dave install a Vais muzzle brake. Dave fitted the BAT with a 2 oz. Jewell trigger, mounted a +20 MOA scope rail, then pillar-bedded the BAT into a McMillan Hunter-Class-style fiberglass stock.
Load Development for Varminting
I had selected a few powders and bullets recommended by other 6-6.5×47 shooters and started by seating all the bullets .005″ off the lands. The powders I selected were Varget, Vihtavuori N-550, and Reloder 15.
I was very pleased with the 88gr Bergers. In initial testing, they grouped well and I was able to drive them to 3400 fps easily. As I wanted a gun for long-range varmint work, I was hoping the 1:10″-twist barrel would provide enough stability for the heavier weight bullets. It did — the 10-twist worked great! I was able to shoot the lighter weight bullets and the 88s were superb. With a BC of 0.391, leaving the barrel at 3400, these bullets were still traveling at 2600 fps at 600 yards!
I did a lot of testing, recording group sizes for a variety of different bullets (see below) and powders. With group size/velocity data in a spreadsheet I was able to “crunch the numbers” and choose my preferred loads. The data drew a clear picture of what the rifle shot best. Here is a chart showing comparative group sizes, arranged by bullet type. On the last three lines, powders are listed by average for all bullets.
Choosing a Varmint Bullet for Precision and Performance
Stan Stewart didn’t just grab a box of bullets off the shelf and head off to the varmint fields. He researched a broad selection of varmint bullets suitable for a 10-twist barrel. He did extensive group testing with a wide range of bullets from 70 grains to 90 grains. Shown below is a “line-up” of some of the bullets Stan tested in his gun.
Stan logged all load data, velocities, and group sizes in a very detailed Excel spreadsheet. Stan’s testing revealed that the light bullets delivered superb accuracy, but they were less than ideal for long shots out past 400 yards. Stan tried the Bart’s 70, Sierra 70 BlitzKing, Berger 80, Hornady 87, Berger 88 Lo-Drag, and Berger 90. Among these choices the Berger 88-grainer was the clear winner for long range (see test targets at right). With an 0.391 BC, this unique “Match Varmint High-BC Flat-Base” offers good ballistics, and high velocities. Stan’s average group size with the 88s was 0.40 inches, bettered only by the Bart’s 70-grainer. Stan’s 6-6.5×47 can launch the Berger 88s at a healthy 3400 fps, providing a highly accurate, flat-shooting solution.
Initially, Stan had high hopes for the Hornady 87-grain V-Max. Stan told us “I also tried the 87 gr Hornady but they didn’t perform to expectations. I am a big Hornady fan but these bullets varied in weight and just didn’t want to group well.” [Editor’s Note: While many varmint shooters have had great luck with the Hornady 87gr V-Max, this is not the first report we’ve received of disappointing results with these bullets. In the Editor’s own 8-twist 6BR, the 87s never shot as well as Bergers, Lapuas, or Sierras in the 85-90 grain range.]
Final Thoughts on the 6-6.5×47 Lapua
I have owned three rifles chambered in 22-250 and will always own a rifle in this caliber because it is inherently accurate and drives a 50gr bullet at 3800 fps. No question the 22-250 can be deadly out to 500 yards. However, I’ve found that shooting past 400 yards with the light bullets is difficult if there is any wind at all. That’s why I liked my 6mm AI for those longer shots and why I decided on the 6-6.5×47 Lapua. I couldn’t be happier with my choice. The only thing that could make it better is if Lapua would produce the 6-6.5×47 as an “official” factory 6mm cartridge with 6mm necks right out of the box. But overall, I am very happy with the cartridge, and I thank Dave Bruno for producing a superbly accurate varmint rifle.

Creedmoor Sports has recently expanded and updated the Creedmoor Sports InfoZone. This web resource contains valuable information about reloading, rifle maintenance, marksmanship skills, and gunsmithing. In addition, the InfoZone has Competition Reports, numerous Gear Reviews, and general Shooting Sports News.
For this Saturday Showcase, you’ll find five InfoZone Videos hosted by Bill Gravatt, President of Creedmoor Sports. There are over 85 other videos on the Creedmoor Sports YouTube Channel. Bill Gravatt is an expert on reloading processes and gear. He developed many of the popular tools for Sinclair Int’l, and now he directs operations for Creedmoor Sports.
Reloading Procedures with Bill Gravatt
Here are five helpful videos Bill Gravatt created for the Creedmoor Sports InfoZone. These videos cover a variety of essential processes for handloading. In addition Bill Shows how to find the exact twist rate in your rifle barrels.
How to Determine a Barrel Twist Rate
Bill Gravatt of Creedmoor Sports demonstrates an easy method to determine your barrel’s twist rate. Knowing the twist rate is essential to selecting suitable bullets for your discipline.
How to Seat Bullets with Inline Press
Many top Benchrest and F-Class shooters favor inline presses for bullet seating. With good hand dies (such as Wilson) and a inline Arbor press (such as a 21st Century), you can get great results with super seating depth consistency and very low run-out.
How to Trim Cases with L.E. Wilson Trimmer
There are many ways to trim cartridge brass. If you need to trim hundreds of cases it may pay to have a dedicated power trimmer. However, for most rifle shooters, a good hand trimmer will do the job very well. We regularly use a Wilson trimmer to trim our cases, as demonstrated in this video.
How to Clean Cartridge Cases
It is important to regularly clean cartridge brass. There are many different means. Wiping the outside with a solvent is a good start. For more thorough cleaning inside and out tumbling or wet-tumbling will do the job. After tumbling in media, you should always check the primer pockets and flash holes before loading.
How to Clean Reloading Dies
Cleaning your reloading dies is something that many who reload often neglect. In this 60-second Tech Tip, Bill Gravatt provides some tips on cleaning your reloading dies.

Peterson Cartridge Company (“Peterson”) has released a lengthy, authoritative guide to the 22 Creedmoor cartridge, a popular wildcat based on the 6.5 Creedmoor or 6mm Creedmoor necked down to .224 caliber. We think the .22 Creedmoor would be a great long-range varmint cartridge, similar to the .22-250 Rem, but with a more modern, efficient cartridge design. In addition, some PRS/NRL competitors may turn to the .22 Creedmoor because it has less recoil and is flatter-shooting than the 6mm Creedmoor. In addition, .224-caliber match bullets are typically less expensive than heavier 6mm and 6.5mm projectiles. Less recoil, and less cost — what’s not to like?*
Along with load data, this article has specific sections dedicated to: Primers, Rifling Twist Rates, and Reloading Supplies. If you are considering building a .22 Creedmoor, we recommend you download the full Peterson .22 Creedmoor article, which is available in PDF format.
Peterson states, “Since its inception in 2007… the 6.5 Creedmoor has seen some pretty meteoric growth in popularity. That growth continues as of this writing, as the cartridge has now gone mainstream with hunters and shooters alike. As the popularity of the 6.5 Creedmoor has increased, so has the number of wildcat cartridges based off of it. Some of those popular wildcat cartridges are the 6mm Creedmoor, the .25 Creedmoor, and now the .22 Creedmoor. This data sheet will cover the .22 Creedmoor.
To help our customers, and anyone else who shoots .22 Creedmoor, we decided to create this Data Sheet and distribute it. [In this LOAD DATA Document] you will find four (4) common bullets, and four (4) common rifle powders used when handloading the .22 Creedmoor cartridge. We then took the different bullet and powder combinations and loaded them up to the SAAMI Maximum Average Pressure (MAP) for the 6.5 Creedmoor and 6mm Creedmoor cartridges, which is 62,000 PSI. [O]ur goal was to provide a wide spectrum of bullet weights and the powders used with them.
All of the following data was gathered by our ballistician in our indoor ballistics lab located in our factory in Pennsylvania. Although we were able to gather pressure and velocity data in our lab, we have NOT tested these loads for accuracy. Again, these loads are just designed to give shooters information regarding what velocity, a given bullet and powder charge combination, will produce the SAAMI Maximum Average Pressure (MAP) of 62,000 psi.”
Sample 22 Creedmoor LOAD DATA
IMPORTANT — Pressures can vary significantly with different Cartridge Overall Lengths (COAL). In addition, ANY change to ANY load components — primers, bullets, brass, powder — can affect pressure. Always load conservatively. In addition, because of variances in bore dimensions, some barrels may show higher pressures than others. Again, always start with conservative loads, well below MAX pressures.
*Actually there IS a potential downside — reduced barrel life. We expect that a .22 Creedmoor running hot varmint loads would experience shorter useful barrel life compared to a 6.5 Creedmoor. This is based on what we’ve observed with .22-250 and .22-250 Ackley barrels compared to our 6.5 CM barrels.
The shape of powder grains has a profound effect on the performance of the powder charge, as it concerns both pressure and velocity. There are multiple powder shapes including flake, ball, and extruded or “stick” (both solid and perforated).
So how does powder grain shape affect pressure and muzzle velocity?
In general, it can be said that powder that burns progressively achieves a desired muzzle velocity at lower maximum pressure than a powder that burns neutrally, not to mention a degressive powder. As grain size increases, the maximum pressure moves towards the muzzle, also increasing muzzle blast. Muzzle velocity and pressure can be adjusted by means of the amount of powder or loading density, i.e. the relationship between the powder mass and the volume available to it. As the loading density increases, maximum pressure grows.
All Vihtavuori reloading powders are of the cylindrical, single-perforated extruded stick type. The differences in burning rate between the powders depend on the size of the grain, the wall thickness of the cylinder, the surface coating and the composition. Cylindrical extruded powders can also have multi-perforated grains. The most common types are the 7- and 19-perforated varieties. A multi-perforated powder grain is naturally of a much larger size than one with a single perforation, and is typically used for large caliber ammunition.
Other types of powder grain shapes include sphere or ball, and flake. The ball grains are typically used in automatic firearms but also in rifles and handguns. The ball grain is less costly to produce, as it is not pressed into shape like cylindrical grains. Flake shaped grains are typically used in shotgun loadings.
Web thickness in gunpowder terminology means the minimum distance that the combustion zones can travel within the powder grain without encountering each other. In spherical powders, this distance is the diameter of the “ball”; in flake powder it is the thickness of the flake; and in multi-perforated extruded powders it is the minimum distance (i.e. wall thickness) between the perforations.
The burning rate of powder composed of grains without any perforations or surface treatment is related to the surface area of the grain available for burning at any given pressure level. The change in the surface area that is burning during combustion is described by a so-called form function. If the surface area increases, the form function does likewise and its behavior is termed progressive. If the form function decreases, its behavior is said to be degressive. If the flame area remains constant throughout the combustion process, we describe it as “neutral” behavior.
The cylindrical, perforated powders are progressive; the burning rate increases as the surface area increases, and the pressure builds up slower, increasing until it reaches its peak and then collapses. Flake and ball grains are degressive; the total powder surface area and pressure are at their peak at ignition, decreasing as the combustion progresses.

Sierra Bullets has released extensive load data for the popular 6.5 Creedmoor cartridge. This medium-sized cartridge has become one of the most popular chamberings for tactical and PRS shooters. The 6.5 Creedmoor combines excellent accuracy, good mag-feeding, good barrel life, moderate recoil, and reasonable component cost. That’s why this cartridge has caught on quickly, and is now one of the most popular chamberings in factory rifles.
Developed in 2007 by Dennis DeMille and Dave Emary, the 6.5 Creedmoor is a shortened and improved 30 TC cartridge case that was inspired by the .308 Winchester design. This short action design was created to maximize case capacity and a wide range of loading lengths, while still fitting in standard short action magazines. With the correct twist barrel, the versatile 6.5 Creedmoor can take advantage of the wide range of bullet weights available in 6.5 mm (i.e. .264 caliber). Reloaders should keep in mind that the 6.5 Creedmoor works best with medium to medium-slow powders such as H4350, Varget, Win 760, and RE-17. The light recoil and adaptability of the efficient 6.5 Creedmoor cartridge has already proven itself in high power, precision rifle series and benchrest competitions. Couple that with respectable barrel life and its intrinsic accuracy potential and you have a recipe for success which should insure its legacy for decades to come.
Here are three tables from the Sierra Bullets Reloading Manual (5th Edition). IMPORTANT — This is just a sample!! Sierra has load data for many other 6.5mm bullet types, including FB, Spitzer, SBT, HPBT, and Tipped MK from 85 grains to 142 grains. To view ALL 6.5 Creedmoor DATA, CLICK HERE.

This article, which offers important insights on COAL, primers, crimps and more.
Precision Pistol Reloading — Recommended Methods
Optimize the Taper Crimp
One often-overlooked aspect of handloading highly-accurate pistol ammunition is the amount of crimp and its effect on accuracy. Different amounts of taper crimp are used with various handloads to obtain best accuracy. The amount is based on bullet weight, powder burn rate and charge, plus other factors. It is not unusual for our Shop to vary a load’s crimp in degrees of 0.001″ and re-test for finest accuracy.
Use Consistent Brass
Brass is also important to pistol accuracy. While accurate ammunition can be loaded using brass of mixed parentage, that is not conducive to finest results, particularly at 50 yards. It is important for the serious competitor/handloader to use brass of the same headstamp and ideally one lot number, to maximize uniformity. Given the volumes of ammunition consumed by active pistol competitors, using inexpensive, mixed surplus brass for practice, particularly at the “short line” (25 yards), is understandable. However, for the “long line” (50 yards), purchasing and segregating a lot of high-quality brass to be used strictly for slow-fire is a wise idea.
Importance of Uniform COAL
Uniformity of the Case Overall Length (COAL) as it comes from the factory is also important to achieving utmost accuracy. More uniform case lengths (best measured after sizing) contribute to greater consistency of crimp, neck tension, ignition/burn of powder charge, and so on. Cartridge case-length consistency varies from lot to lot, as well as by maker. Some manufacturers are more consistent in this dimension than others. [Editor’s note: It is easy to trim pistol brass to uniform length. Doing this will make your taper crimps much more consistent.]
Primers and Powders — Comparison Test for Accuracy
Pay attention to primer brands, powder types and charges. Evaluating accuracy with a Ransom or other machine rest at 50 yards can quickly reveal the effect of changes made to handload recipes.

Bullet Selection — FMJ vs. JHP
Bullets are another vital issue. First, there is the question of FMJ vs. JHP. A friend of this writer spent decades making and accuracy-testing rifle and pistol bullets during QC for a major bullet manufacturer. In his experience, making highly-accurate FMJ bullets is much more difficult than making highly-accurate JHPs, in large part due to the way the jackets are formed. Small die changes could affect accuracy of FMJ lots dramatically.
The CMP now allows “safe, jacketed ammunition” in Excellence-in-Competition (EIC) Service Pistol matches, although wadcutter ammunition is prohibited. Thus, the option to use very accurate JHP designs simplifies the life of CMP Service Pistol shooters in pursuit of the Distinguished Pistol Shot badge.
Hopefully, these tips will be helpful to any pistol shooters interested in accurate handloads, not just “Bullseye” shooters. Small tweaks to one’s normal routine can pay big dividends in improved accuracy and make practice and competition more rewarding.
