Want to learn more about Long Range Shooting? Check out the NSFF “Elements of Long Range Shooting” videos hosted by ballistics guru Bryan Litz of Applied Ballistics. In this multi-part series, Bryan covers a variety of topics of interest to precision shooters. For today’s Saturday at the Movies special, we feature seven of Bryan’s videos. Watch other informative Long Range Shooting and Ballistics videos with Bryan Litz on the NSSF YouTube Channel.
Atmospherics and Density Altitude
Bryan Litz explains: “An important element in calculating an accurate firing solution for long-range shooting is understanding the effects of atmospherics on a projectile.” Atmospherics include air pressure, air temperature, and humidity. Bryan notes: “Temperature, pressure, and humidity all affect the air density… that the bullet is flying through. You can combine all those factors into one variable called ‘Density Altitude’.” Density Altitude is used by the ballistic solver to account for variables that affect bullet flight.
Bullet Ballistic Coefficients
A bullet’s ballistic coefficient (BC) basically expresses how well the bullet flies through the air. Higher BC bullets have less aerodynamic drag than lower BC projectiles. You will see BCs listed as either G1 and G7 numbers. These correspond to different bullet shape models. Generally speaking, the G7 model works better for the long, boat-tail bullets used for long-range shooting. Notably, a bullet’s drag is NOT constant in flight. The true BC can vary over the course of the trajectory as the bullet velocity degrades. In other words, “BC is dynamic”. That said, you can make very accurate drop charts using the BCs provided by major bullet-makers, as plugged into solvers. However, long-range competitors may want to record “real world” drop numbers at various distances. For example, we’ve seen trajectories be higher than predicted at 500 yards, yet lower than predicted at 1000.
Transonic Range
When considering your rifle’s long-range performance, you need to understand the limit of your bullet’s supersonic range. As the bullet slows below the speed of sound, it enters the transonic zone. This can be accompanied by variations in stability as well as BC changes. Bryan explains “once your bullet slows done below supersonic and you get into transonic effects, there are a lot more considerations that come into play. The drag of the bullet becomes less certain, the stability of the bullet can be challenged, and things related to long times of flight, such as Coriolis and Spin Drift, come into play. So whenever you are shooting long range you need to where your bullet slows down to about 1340 fps.”
Ballistics Solvers — Many Options
Bryan Litz observes: “When we talk about the elements of long range shooting, obviously a very important element is a getting a fire solution, using a ballistic solver. There are a lot of ballistic solvers out there… Applied Ballistics has smartphone Apps. Applied Ballistics has integrated the ballistic solver directly into a Kestral, and the same solver runs (manually) on the Accuracy Solutions Wiz-Wheel. The point is, if it is an Applied Ballistics device it is running the same solutions across the board.”
Bullet Stability and Twist Rates
In this video, Bryan Litz talks about bullet in-flight stability and how to calculate barrel twist-rate requirements for long-range bullets. Bryan explains that bullet stability (for conventional projectiles) is basically provided by the spinning of the bullet. But this spin rate is a function of BOTH the nominal twist rate of the barrel AND the velocity of the projectile. Thus, when shooting the same bullet, a very high-speed cartridge may work with a slower barrel twist rate than is required for a lower-speed (less powerful) cartridge. For match bullets, shot at ranges to 1000 yards and beyond, Bryan recommends a twist rate that offers good stability.
Scope Tracking — Tall Target Test
Have you recently purchased a new scope? Then you should verify the actual click value of the turrets before you use the optic in competition. While a scope may have listed click values of 1/4-MOA, 1/8-MOA or 0.1 Mils, the reality may be slightly different. Many scopes have actual click values that are slightly higher or lower than the value claimed by the manufacturer. The small variance adds up when you click through a wide range of elevation. In this video, Bryan Litz shows how to verify your true click values using a “Tall Target Test”. The idea is to start at the bottom end of a vertical line, and then click up 30 MOA or so. Multiply the number of clicked MOA by 1.047 to get the claimed value in inches. For example, at 100 yards, 30 MOA is exactly 31.41 inches. Then measure the difference in your actual point of impact.
Coriolis Effect
The Coriolis Effect comes into play with extreme long-range shots. The rotation of the earth actually moves the target a small distance (in space) during the long duration of the bullet’s flight. Bryan Litz notes that, in most common shooting situations inside 1K, Coriolis is not significant. At 1000 yards, the Effect represents less than one click (for most cartridge types). Even well past 1000 yards, in windy conditions, the Coriolis Effect may well be “lost in the noise”. But in very calm conditions, when shooting at extreme ranges, Bryan says you can benefit from adjusting your ballistics solution for Coriolis: “The Coriolis Effect… has to do with the spin of the earth. The consequence of that is that, if the flight time of the bullet gets significantly long, the bullet can have an apparent drift from its intended target. The amount [of apparent drift] is very small — it depends on your latitude and azimuth of fire on the planet.”

Put the same load in a variety of barrels (with the same length and chamberings) and you’ll see a wide variance in muzzle velocity. In fact, it’s not unusual to see up to 100 fps difference from one barrel to the next. We demonstrated this with a comparison test of Lapua factory ammo.
Chron Testing Lapua Factory Ammo
At our Southern California test range some years ago, we chronographed Lapua 105gr 6mmBR factory ammo in three different 8-twist barrels of similar length. The results were fascinating. Lapua specs this ammo at 2790 fps, based on Lapua’s testing with its own 26″ test barrel. We observed a speed variance of 67 fps based on tests with three aftermarket barrels.
Barrel Velocity Variance
Brand ‘S’ and Brand ‘PN’ were pre-fit barrels shot on Savage actions. Brand ‘K’ was fitted to a custom action. All test barrels were throated for the 100-108 grain bullets, though there may have been some slight variances in barrel freebore. With a COAL of 2.330″, the rounds were “jumping” to the rifling in all barrels.
Among the four barrels, Brand ‘PN’ was the fastest at 2824 fps average — 67 fps faster than the slowest barrel. Roughly 10 fps can be attributed to the slightly longer length (27″ vs. 26″), but otherwise this particular barrel was simply faster than the rest. (Click Here for results of 6mmBR Barrel Length Velocity Test).
IMPORTANT: Results Are Barrel-Specific, Not Brand-Specific
These tests demonstrate that the exact same load can perform very differently in different barrels. We aren’t publishing the barrel-makers’ names, because it would be wrong to assume that ‘Brand X’ is always going to be faster than ‘Brand Y’ based on test results from a single barrel. In fact, velocities can vary up to 100 fps with two identical-spec barrels from the SAME manufacturer. That’s right, you can have two 8-twist, 26″ barrels, with the same land-groove configuration and contour, from the same manufacturer, and one can be much faster than another.
Don’t Demand More Than Your Barrel Can Deliver
We often hear guys lament, “I don’t get it… how can you guys get 2900 fps with your 6BRs and I can only get 2840?” The answer may simply be that the barrel is slower than average. If you have a slow barrel, you can try using more powder, but there is a good chance it may never run as fast as an inherently fast barrel. You shouldn’t knock yourself out (and over-stress your brass) trying to duplicate the velocities someone else may be getting. You need to work within the limits of your barrel.
Factory Ammo Provides a Benchmark
If you have a .223 Rem, 6mmBR, .243 Win, 6.5×47 Lapua, 6.5 Creedmoor, 6.5×55, .308 Win, .30-06 Springfield, or .338 LM Rifle, we recommend you buy a box of Lapua factory-loaded ammo. This stuff will shoot great (typically around half-MOA), and it can give you a baseline to determine how your barrel stacks up speedwise. [Editor’s NOTE: The original test was conducted in 2008. The velocity of current-production Lapua factory ammo might be higher or lower, so your results may vary.]
When you complete a new 6mmBR rifle, it’s definitely smart to get a box of the factory ammo and chronograph it. That will immediately give you a good idea whether you have a slow, average, or fast barrel. Then you can set your velocity goals accordingly. For example, if the factory 6BR ammo runs about 2780-2790 fps in your gun, it has an average barrel. If it runs 2820+ in a 26″ barrel (or 2835 fps in a 28″), you’ve got a fast tube.

A while back, Cal Zant at PrecisionRifleBlog.com did a big muzzle brake comparison test. Along with measuring recoil reduction, Cal’s team recorded sound levels in PRB’s exhaustive muzzle brake field test. In the PRB archives you’ll find comprehensive muzzle brake sound test results, with hard data on 20 different muzzle brakes.
Sound can be a tricky subject, but Cal Zant, the editor of PrecisionRifleBlog.com, presents everything an informed shooter should know about muzzle brake noise in a straightforward and practical way. Most sound tests are measured from the side of the muzzle, in accordance with mil-spec standards, and Cal did that. But he also measured the sound level of each brake from behind the rifle, closer to the shooter’s position. This provides a more accurate indicator of the actual sound levels firearms operators will encounter while shooting.
Muzzle brakes ARE really loud — that’s something most active shooters have observed. But this study finally gives us some hard data and makes objective comparisons. The difference between brakes was quite significant. Some brakes were ear-splitting — more than twice as loud as other brakes tested.
As a bonus, Cal also provides data on how the new Ultra series suppressors from Thunder Beast Arms Corp (TBAC) compare in terms of sound level behind the rifle.

Some of America’s most prestigious rifle matches take place at Camp Perry, Ohio over the next 17 days. The 800 Aggregate is underway now. The President’s 100 Match will be held on Monday, July 29th, followed by Individual and Team Trophy Matches. And the Garand and Modern Military events run the first weekend in August. For those competing at Camp Perry this month, we offer some insights from Tyrel Cooper, a multi-time National Champion. A past member of the USAMU, Cooper’s shooting resume includes five national championships (one each in 2008, 2011, 2012, and two in 2013). He won the 2013 NRA National Long Range Championship, as well as the 2013 NRA National Service Rifle Championship. In this article, written in 2014, Cooper explains the mental preparation that helped him win National Titles in 2013.
Below is a 2012 file photo of Ty Cooper shooting a service rifle. Cooper won the 2013 Long Range Championship using a Nesika-actioned bolt gun chambered in 7mm SAUM.
Mental Preparation by Tyrel Cooper Getting focused mentally is an important part of preparation for Perry. In 2011 I was chasing Sherri Gallagher, since then I have been chasing Brandon Green[.] If I get beat by a Service Rifle I am going to make him or her work for it. So there is your peak into my mental process. I go for the top and if I am hanging with them then the Service Rifle National Championship will come, Kind of like how I shoot for X’s and Tens will come.
Now I understand everyone is at different levels. You have to figure out what your goals are and then lie to yourself that you’ve already achieved them. Here is a trick that I used back in 2008: When I was a kid just starting out, my Dad made me read several books on shooting. One of them being With Winning In Mind by Lanny Bassham. One of the things I remember from his book is that he would make notes and place them where he would see them often. They contained his goals or stated he was already a world champion. I took a page from his book and did the same thing.
I made 3×5 cards and wrote my personal best 500 and 800 aggregate scores and taped on the horn of my truck, above the radio in my truck, on my laptop and a few other places I would see them often. Every time I saw those I would tell myself that I average those scores and I would get used to seeing them. By doing this you are lying to yourself to overcome the mental blocks the subconscious mind lays out for you.
I went from my worst year in 2007 to winning my first National Championship in 2008. I kind of slacked off in 2009 because I had reached my goals and didn’t set new ones and it showed, so I had to find new goals and motivation which I did and that pushed me back to the top.
Long story short, this is a mental sport and you have to figure out what you need to do to perform at your highest levels and breaking through those mental road blocks. You have to figure out how to get yourself to relax and control your mind keeping calm when you are shooting a personal best, either standing or on the day.
Here is a tip from my mental process from shooting. First I shoot for Xs, I took the line from the movie The Patriot and applied it to my shooting, “Aim small, miss small” and it is true. If you accept wide shots then you will keep shooting wide shots.
Winning Techniques for Rifle Competition
Slow, Solid, Smooth, Center
Always focus on the positive and good shots, and what you did physically and mentally, when you shot them. When I am nervous and need to calm myself down I tell myself: slow, solid, smooth, center.
Slow
I want my movement to be slow…
I can shoot Tens and Xs all day with slow movement.
Solid
Solid like a rock, a rock doesn’t move and that’s how I want my positions. By saying solid it reminds me to go through my little checks to make sure I am doing what I need to do make that happen.
Smooth
Smooth — that is my trigger word for smooth movement. You don’t want fast choppy movement but slow and smooth. This also reminds me to be smooth on the trigger. You can be smooth-fast or you can be smooth-slow but you have to be smooth and most people aren’t when they think they are. Just before leaving the USAMU, I walked up and down the line of five shooters during a rapid fire string and only one of them was smooth with their trigger control. It’s the second most important thing when it comes to shooting.
Center
This reminds me that I want my shots in the middle. It is just a positive reinforcement of where I want my shots to go. I shoot a reverse flat tire so it also kind of reminds me as to what I am looking for.

A new report from a voter registration group demonstrates the big impact hunters, recreational shooters, and other American gun owners could have on federal, state, and local elections if they register to vote and then vote in the upcoming November election. The Second Amendment community needs to make sure that the 22.3 million new first-time gun owners since 2020 are registered to vote and then vote this November. NSSF’s #GUNVOTE initiative was created to do just that and according to the newly released survey data from Vote4America, the outcome of the upcoming November presidential election could be determined by Second Amendment supporters.
The key objective should be to increase voter registration numbers for firearms owners, and encourage them to vote this November. According to the Vote4America survey, large numbers of gun owners and hunters in critical swing states are NOT registered to vote. Nationwide, an estimated 10 million gun owners and hunters are NOT registered. In a breakdown by state, the data shows unregistered hunting and Second Amendment supporters total at least 515,277 in Pennsylvania. That number is closer to around 370,000 each in Michigan and North Carolina. In addition, Georgia, Wisconsin, Missouri and Virginia “all have more than half a million hunters and gun owners unregistered,” and in Arizona that number totals approximately 133,000.
In a District of Conservation podcast, Vote4America adviser Baker Leavitt said, “If we could convert 2% of all licensed hunters and get them to vote, [the] GOP would win in a landslide.”
INFO on Registering to Vote, Voting Process, and Polling Places
The GunVote.org website has links to official state websites where more details about registering to vote, early voting protocols, and the entire process can be found. For those who wait until election day to cast their ballot, GunVote.org also has comprehensive lists of polling place locations where citizens can vote in their city/state.
Second Amendment rights and the rights of hunters and recreational target shooters are on the ballot every election. If you have a friend or loved one who loves hunting and recreational shooting sports, do your part and make sure they register to vote and then vote in November. If they have questions about how to register, send them to GunVote.org.

The Henry AR-7 Survival rifle is a unique rifle. Weighing just 3.5 pounds, this little semi-auto rimfire can perform pest-control duties for a farmer or rancher, or serve as a utility rifle carried in a truck or ATV. The cleverly-designed AR-7 is affordably priced, just $299.99 at Sportsman’s Warehouse.
We think most gun-owners would enjoy adding an AR-7 to their collection. The Henry AR-7 breaks down for easy carry in a backpack or a vehicle. The barrel, receiver, and magazines all fit INSIDE the buttstock. That’s handy. And this little 3.5-pound rifle offers surprisingly good accuracy.
If you don’t like basic black, Henry offers two camo versions from the factory: True-Timber Kanati Camo, and Viper Western Camo. Click the photo below for full-screen (2048 pixel wide) image:
Or, if you have artistic skills (and confidence with spray cans), you can paint your AR-7 yourself, as this owner did. The talented gun-painter reports: “[This is a] great little gun that is accurate and I love how it packs away. I paint all my black guns. Already took a grouse at 16 yards.”
History of the Henry AR-7 Rifle
Starting in 1959 the AR-7 was provided to U.S. Air Force fliers as a survival rifle to use if they were stranded in a remote area. Today the AR-7 is a favorite of bush pilots, backpackers, and backcountry adventurers who, like their Air Force counterparts, need a rifle that’s easy to carry yet can take down small game. Like the original Henry U.S. Survival Rifle, this innovative, semi-automatic rimfire rig is lightweight (3.5 lbs.) and highly portable. At just 16.5″ long, with all components stowed, it easily fits into a backpack, or the cargo area of an ATV, truck, boat. or plane. The AR-7 is chambered in .22 LR so you can carry plenty of ammo without adding much weight to your gear. When disassembled, all the pieces fit inside the impact-resistant, water-resistant stock.
Assembly is as easy as attaching the receiver to the stock, inserting the barrel, and screwing on the barrel nut. In a few seconds, without any tools, the Henry U.S. Survival AR-7 is ready for action. It now comes standard with a steel barrel covered in tough ABS plastic with a protective coating for corrosion resistance. The Henry U.S. Survival AR-7 is available in three finishes; Black, True Timber Kanati Camo Pattern, and True Timber Viper Western Camo Pattern. All models are equipped with an adjustable rear sight and a blade front sight. As you can see below, the built-in storage can be used to hold magazines and ammunition as well as the rifle components.
Another AR-7 owner posted this review:
Simple Goodness: Henry AR-7 — Fun Modern Version of a Classic
Henry got this modern take of the AR-7 right. Gentle finger-tighten is all it takes to assemble. The funky orange plastic sight on the end of the barrel is kind of loud, but was also easy to target with. Brand spanking new, I was getting grapefruit-sized patterns out of each 8-round mag at 50 feet. For a compact take-down, was surprised that length-of-pull was satisfactory for a six-foot guy. It didn’t feel cramped.
For realistic backpack, bail-out, or bug-out situations this would be a smart choice. It was fussy with a single Rem Golden in the first mag… but after that no problems, and no issues at all with Federal and CCI. The safety is right-handed but large and easy to get used to. The charge handle retracts so [you must] pull it up before pulling back, but that motion seemed to become reflexive pretty quickly. The mag eject is in front of the trigger and pushes forward. All in all, [the AR-7 offers a] really nice, compact form factor. [It is] light, perfect for backpack plinking and … low-rent varmint sniping.
At the request of our Shooters’s Forum members, we’re repeating an excellent article by Steven Blair on wind reading. Steven, a top F-Class shooter, talks about mirage, topography effects, tail winds, and other subtle factors that can cause frustration for shooters. Steve explains that wind effects can be complex — there’s more going on than just velocity and angle. You need to notice things like berm locations and effects of temp changes over the course of the day.
Wind Reading Tips for Competitive Shooters by Steven Blair, Past California State Long Range F-Open Champion
Assess the Terrain and How the Wind Will Interact with It
Before you begin a match, take a few minutes to look around the range at the terrain, any obstructions, range topography (berms and backstop), and trees, buildings or structures that could affect wind flow over the range. Imagine what might happen if the wind was from the left or right, headwind or tailwind. Depending upon the direction, significant effects may be seen on range. A head or tail wind may ripple across the berms, causing elevation changes, both high and low. A tall side berm, like the east side berm at Ben Avery, may cause turbulence when the wind comes from that direction. Blocking features might shield most of the wind but a break along the range can funnel strong gusts through the gap with no other indications. Take a few notes about the effects of different wind directions and refer to them if the prevailing direction changes. (Tip courtesy Tony Robertson.)
Use a Spotting Scope, Even When Shooting a Scoped Rifle
A good spotting scope can “see” mirage much more clearly than even an expensive rifle scope. Take your spotting scope to the line and position it as sling shooters do, close enough to use without much movement. Focus the scope approximately 1/3 of the way down range or where the most significant wind effects are likely to occur. Take a quick look while waiting for pit service, glance at the flags and compare to your scope sight picture. I often see ambiguous indications at the target through the rifle scope, but see a clear indication of wind direction and speed through the spotting scope at the shorter distance. When shooting the Arizona Palma Championship at Ben Avery last weekend, I was scoring while the wind was coming from the east. Shooters up and down the line were out to the left, losing points. Mirage at the target looked moderate and the flags weren’t indicating strong wind. As I focused the spotting scope back, the mirage suddenly looked like it was flowing twice as fast around 500 yards than it was closer or farther. It wasn’t until I realized that the access road cut through the berm there that I understood what was happening. (Tip courtesy Gary Eliseo.)
Don’t Over-React to Something That May Be an Anomaly
On ranges with sizable berms, a headwind or tailwind can cause significant elevation problems. It is generally not possible to see or predict when this will occur. When the conditions exist that cause elevation changes and other competitors are experiencing the same problem, the best strategy is to ignore it. Certainly, avoid shooting when the head or tail wind is gusting, the same as you would in a crosswind. But, if you react to random, range-induced elevation changes, the only likely result is to make it worse. Whether the problem is caused by range or ammunition, maintain your waterline hold until you have evidence that something has fundamentally changed.
My .284 Shehane will usually require a click or two down during a string as the barrel warms. That is normal and manageable. But, if your shots are just bouncing up and down in the 10 ring, leave it alone. The same is also true of an occasional gust pushing a shot into the 9 ring. If the conditions have not changed and one shot just went out, it may be the result of a random occurrence that was not predictable. (Tip courtesy “School of Hard Knocks”.)
Adjust Spotting Scope Focus and Magnification as Needed to View Mirage vs. Target Details
In F-Class we only need to see mirage, spotters, and scoring disks. That does not take a lot of magnification. My scope is a Nikon 25-75x82mm ED. It is a superb scope for the money and makes it trivial to see minor variations in mirage. It is good to have the high magnification available, and it can always be reduced if necessary. I use different power settings for different situations.
Setting Magnification Levels
During a match, in very good viewing conditions, I set my spotting scope at 75X, full power. The mirage is more subtle in the morning and greater magnification is needed.
During a match with heavy mirage I set my spotting scope at about 40X. I have no problem seeing mirage, even at this magnification.
When practicing at 300 yards or closer I set my spotting scope at max power (75X) so I can see the little 6mm holes from my 6BR rifle. I usually need to focus back and forth between shots to see both bullet holes and mirage.

In our Shooters’ Forum, there’s an interesting thread about a very light hunting rifle. Featuring a Defiance ultra-light all-steel action, this 6.5×57 Lapua lightweight tips the scales at just 4.93 pounds including scope and rings! For reference, a half-gallon of milk weighs 4.3 pounds, so this rifle is LIGHT! Here’s a report from the proud owner who built the rifle for a future Kodiak Island Alaska mountain goat hunt.
Ultralight Rifle Report by Forum Member Dave
I decided I wanted the challenge of a Mountain Goat hunt after I turn 60. It was the perfect excuse to put together an ultralight, something I had wanted to do for years. I wanted to see how light a bolt action rifle could actually be. My goal was to stay under 5 pounds, without going to a Titanium action, including rings and scope. I knew this would be difficult but I did manage to achieve the goal.
I started with a Defiance anTi model Rem Model 7 short action. This is an extremely smooth action that weighs just 19.2 ounces in this size. I had Carson Lilja of Lilja Barrels program a barrel taper to my dimensions for a 6.5mm 1:8″-twist stainless, 3-groove 22″ barrel. As fitted in the rifle, the barrel is free-floated except for the first inch or so forward of the action.
Other rifle components are: Bix n Andy Dakota trigger, aluminum trigger guard, blind magazine with an aluminum follower, titanium action screws, and a Leupold 3-9X lightweight optic in Talley rings. I also had an aluminum adapter installed in the for-end to accept a magnetic mount Javelin carbon fiber bipod.
The rifle was chambered up in 6.5×47 Lapua by my friends at Sportsman’s Outfitters in Knox, Pennsylvania. Then I sent the barreled action to Wayne at Oregunsmithing (Pendleton, OR) to have a Kevlar stock built. The stock weighs a whopping 14 ounces! When it came back I had everything Cerakoted (see bottom photo before coating). This stock was a full custom, built around my barreled action. Wayne’s work was reasonably priced with a 3-month turn around.
Excellent Accuracy — 5/8″ Three-Shot Groups at 100 Yards
Now it was time to shoot the rifle and I was not disappointed. It shoots both Barnes TTSX 100s or Swift Scirocco II 130s into 5/8″ at 100 yards. Off a bipod at 400 yards, three go into 3″ or so. This thing is crazy light even though it wears a 22″ barrel.
Without scope and rings, before Cerakoting the action and barrel, this 6.5×47 rifle tipped the scales at a mere 4.20 pounds (67.2 ounces). Check it out:

Here’s an inexpensive procedure that can help you load straighter ammo, with slightly better measured concentricity (i.e. less run-out) on the case necks and bullets. Simply use a Rubber O-Ring on the underside of the die locking ring. This allows the die to self-align itself (slightly) to the case that is being sized. Without the O-Ring, if the flat surface on the top of your press is not perfectly square with the thread axis, your die can end up slightly off-angle. This happens when the bottom of the locking ring butts up tight against the top of the press. The O-Ring allows the die to float slightly, and that may, in turn, reduce the amount of run-out induced during case sizing.
Top prone shooter GSArizona, who sadly passed in 2022, tried this trick and said it works: “Go to your local hardware store and get a #17 O-Ring (that’s the designation at Ace Hardware, don’t know if its universal). Slip the O-Ring on the die and re-adjust the lock ring so that the O-Ring is slightly compressed when the die is at the correct height. Size and measure a few more cases. You will probably see a slight improvement in neck concentricity as the die can now float a bit as the case enters and leaves it. This isn’t going to be a dramatic improvement, but it’s a positive one.”
We want to stress that adding O-Rings to sizing dies may help some reloaders, but we don’t offer this as a panacea. Try it — if using the O-Ring reduces measured runout that’s great. If it doesn’t, you’ve only spent a few pennies to experiment.
Lee Precision makes die lock rings with built-in O-Rings. Lee’s distinctive lock ring design allows the same kind of self-alignment, which is good. However, Lee lock rings don’t clamp in place on the die threads, so they can move when you insert or remove the dies — and that can throw off your die setting slightly. By using an O-Ring under a conventional die lock ring (that can be locked in place), you get the advantages of the Lee design, without the risk of the lock ring moving.

The 2024 NRA National Matches at Camp Atterbury, Indiana commence next week on July 22, 2024, and then run through August 19, 2024. Top rifle competitors will be looking to have their names associated with famous NRA perpetual trophies. This article covers the history of notable trophies including the Leech Cup, the Wimbledon Cup, and the Palma Team Trophy.
Shooting Sports USA has a fascinating article about the Perpetual Trophies awarded in national-level NRA matches. The story recounts the history behind the elaborate trophies, some from the 1870s. SSUSA’s Jennifer Pearsall writes: “The pieces of wood, stone and precious metal … are more than just instant recognition of achievement. They are the link of the American shooter’s present to his or her patriotic past. As you read this legacy of the NRA ranges, their founders, and the long list of cups, bowls, and plaques, realize that the history of competitive shooting is undeniably a significant part of the foundation of this country”. Read Full Trophy Story HERE.
The NRA was co-founded by Col. William Church and Gen. George Wood Wingate (ranked Captain at the time). Both Church and Wingate hoped to improved the marksmanship skills of American soldiers. One of the newly-formed NRA’s first actions was to issue: “An Act to Establish a Rifle Range and Promote Skill in Marksmanship”. That led to the opening of the famed Creedmoor Range, with a special inaugural match in June of 1873.
Many of the awards presented in the first NRA matches were cash or firearms. Some of these firearms were heavily embellished works of art. In the very first match, a member of the 22nd New York Regiment took home a gold-mounted Winchester Model 1866 valued at $100 — big money for the time.
In the 1870s shooting competitions were social as well as sporting events. Ladies and gentlemen came to watch and cheer the winners. This illustration, originally from Harpers Weekly, portrays the shooters and the viewing gallery at the 1876 Grand Centennial Championship—the “Palma” Match.
The Leech Cup — A Gift from Ireland
The Leech Cup was created for the first meeting of the American and Irish shooting teams. The elaborate cup was presented by Major Arthur Leech, captain of the the Irish team, to the Amateur Rifle Club of New York. This masterpiece of Irish silversmithing was later given to the NRA in 1901 by the New York Club. Today, the Leech Cup is the oldest trophy offered in overall NRA competitive target shooting, awarded through the National High Power Long Range Championships.

The Wimbledon Cup
The Wimbledon Trophy was a gift from the NRA of Great Britain. It was given, as a gesture of sportsmanship, after the the U.S. Team was denied the ability to compete in England’s Elcho Shield match, then limited to Britain, Scotland, and Ireland. To maintain friendly competitive relations, the British presented the Americans with a large, engraved, lion-footed tankard trophy to be awarded each year to the Champion U.S. long-distance rifleman.
The Palma Team Trophy
Originally named the Centennial Trophy, in honor of the Centennial celebration of the independence of the United States of America, the Palma Trophy was commissioned from Tiffany’s at a cost of $1,500. The trophy was a full-sized replica of a Roman Legion standard, executed in bronze with silver and gold inlay. On the banner of the standard was the legend, “In the name of the United States of America to the Riflemen of the world”. Above the banner was an eagle, bearing in its talons a wreath of palm leaves and a plaque on which was the single word, “PALMA”, the Latin word for palm tree, which was used by the Romans to signify victory, or the ultimate in excellence.
Because the word Palma was so easily seen, the trophy soon became known as the “Palma Trophy”, and by 1878 was referred to officially by that name. The original seven and one-half foot trophy is now lost, having not been seen since at least 1954. Serving in its place is a copy which was commissioned by Dr. Herbert M. Aitken of Eau Claire, WI. The copy was made from the original Tiffany blue-prints at a cost of $32,500. Dr. Aitken has given this copy of the Palma Trophy to the NRA for use in the Palma Match. The trophy is retained by the winning team until the next Palma Match.
In 2008, the Palma Trophy was returned to the NRA, and it was decided that the trophy, once refurbished, will travel to the host nation for the match every four years, then returned to the NRA for safekeeping.
The first competition for the Palma Team was a challenge match for which the British Commonwealth nations were invited. The match was fired in 1876 at the old Creedmoor Range on Long Island as part of the Centennial celebration of the United States. Teams representing Scotland, Ireland, Canada, Australia, and the United States took part. The match is currently fired on a four-year interval.

Adam Scepaniak, of The Guns and Gear Store, has written an interesting story about Prairie Dog Hunting in North Dakota. If a P-Dog safari is on your “bucket list”, you’ll want to read the full story in the Sierra Bullets Blog. Adam provides many tips that can help you plan a successful prairie dog adventure.
Prairie Dog Hunting in North Dakota with Sierra Bullets
It’s that time of year where lots of men and women point their vehicles westward and try to push the limits of their rifles on prairie dogs. [A few seasons back] I was a part of this group of people… while in northwestern North Dakota. CLICK HERE to Read Full Story.
Little Missouri National Grassland
Once my hunting party arrived at the Little Missouri National Grassland in North Dakota we immediately began scouting for prime prairie dog towns. There is a certain amount of strategy involved in choosing a prairie dog town … for several reasons. For one, you should try to always stay “above” the prairie dogs.
Small objects like rocks, cactuses, and prairie vegetation can easily obstruct your view if you’re shooting prone on a level plane. We encountered this in the first small prairie dog town we stopped and shot at. The prairie dog town was very visible while walking and standing, but once we laid down with our rifles on bipods the two-foot prairie grass became a severe obstruction. We shortly moved on because the small town became quick-studies to our shooting.
The second prairie dog town we hunted was at the base of a small ridge with a dried, cattle creek at the bottom. This area offered better shooting opportunities because we were above most of the prairie dog holes, and if we were not above them, a deep ravine separated us from the prairie dogs removing any obstructions from our rifle scopes which was our previous problem. This area had its own disadvantage though because of some other wildlife present. There were approximately fifty head of cattle in our close vicinity grazing, which was to no surprise because many ranchers utilize the National Grassland for grazing. We had to wait for the cattle to leave our area as to not have an incidental hit due to a rare ricochet. As the sun passed over the horizon we decided to return to this spot the next morning, but would change our shooting position to increase our advantage.

My previous varminting best was a 275-yard shot near Mobridge, South Dakota on a separate prairie dog hunting trip. With more experience and better reloading, Here in North Dakota I was able to make a solid hit on a prairie dog just over 400 yards which made me ecstatic! For a central Minnesota, shotgun-raised guy, I was pretty happy that my bullet selection and hand-loading ability produced a 125-yard improvement.
Once we cleaned and cased our rifles for the journey home we had shot a little over 200 rounds of my Sierra® reloads. This was a lot less than previous prairie dog trips I have been a part of, but our hit percentage was substantially higher as well. Traveling into a new area meant a lot more scouting and experimentation for us as a group. In future trips or hunts of your own, it can be very beneficial to schedule an extra day just for scouting[.]
Little Missouri National Grassland is a National Grassland located in western North Dakota. At 1,033,271 acres, it is the largest grassland in the country. Within its borders is Theodore Roosevelt National Park. The Little Missouri National Grasslands was once a part of the Custer National Forest, but is now a part of the Dakota Prairie Grasslands, a National Forest unit consisting entirely of National Grasslands. A predominant feature of the grassland is colorful and beautiful badlands, a rugged terrain extensively eroded by wind and water. It is a mixed grass prairie, meaning it has both long and short grass.
The boundaries of the grasslands on certain maps can be misleading. Within the boundaries of the national grassland are significant portions of state-owned and privately-owned land, much of it leased by cattle ranchers for grazing.
The grassland is administered by the Forest Service as part of the Dakota Prairie Grasslands from offices in Bismarck, ND. There are ranger district offices in Dickinson and Watford City.

Close-up view of a sectioned case. This one here was “fixin’ to pop”, observed Glen Zediker.
Here are highlights from an article Glen Zediker wrote for the Midsouth Blog. In that article Glen, who sadly passed away in 2020, focused on cartridge brass. Glen identified the most common failures that appear with brass that has been shot multiple times, or which has been fired at excessive pressures. Glen explained some simple ways to check your cartridge brass to detect “early warning signs” of case failure, particularly case head separation, which can be very dangerous.
How Cases Degrade with Multiple Firings By Glen Zediker
This article explains when, and then how, to check after the progress of changes commencing with the firing on a new case. It’s the “progress of degeneration,” in a way of looking at it because the concern is getting a handle on when enough change in the brass has come about to require attention. Or abandonment. As said then, for me that’s 4 firings. That, as said last time, is when I might see changes that need attention. Also as said, that figure didn’t come out of a hat, but from my own notes in running my competition NRA High Power Rifle loads. [Editor’s Note: With Lapua brass, using moderate loads, in bolt-action rifles, we typically get about 10 good (match-worthy) firings. But if you anneal your Lapua brass, and run modest pressures, Lapua brass can perform well for 20 or more load cycles.]
The areas most affected are the case neck and case head area. Case neck walls get thicker [but] the case head area body walls get thinner. Primer pockets get shallower and larger diameter.
This case shows a cracked neck AND a crack (separation) above the case head. Zediker says it is “rare to see one case with both of the most common failures. [This case] was attacked by an M14.”
Case Head — Causes of Separation and Cracking
When a case is under pressure during firing, the brass, like water, flows where it can, where it’s more free to move. Of course, the chamber steel limits the amount it can expand. The case shoulder blows fully forward and the case base is slammed back against the bolt face. There is, therefore and in effect, a tug on both ends — it gets stretched. The shoulder area is relatively free to expand to conform to the chamber, but the other end, the case head area, is not. Since that’s the area of the case with the thickest walls, it doesn’t expand “out” much at all. What it does is stretch. The “case head area,” as I refer to it here, is the portion of the case above the web, which is just above the taper that leads in to the extractor groove. The “area” extends approximately an eighth-inch up the case body.
Here’s a “pressure ring.” You’ll see this after firing, if you see it. And, if you see it, that case is done. The bright ring indicates excessive stretching, which indicates excessive thinning. If you see a ring circling the case, noticeable because it’s lighter color than the case body, and it’s in this area, I’d say that case is done. And that’s right where a “head separation” occurs. It can crack and also blow slap in two, and that’s the “separation” part of case head separation.

This is a spot to keep close watch on as cases age. It is also the area that is more “protected” by sizing with less case shoulder set-back. That is, pretty much, where the freedom for the stretching movement in this area comes from (the case shoulder creates a gap). If you’re seeing a sign that a head separation [might happen with relatively few firings], chances are the shoulder set-back is excessive, and also… the load pressure level.
Bent Paper Clip Case-Wall Gauge
Editor: You can use a bent paper clip to detect potential case wall problems. Slide the paper clip inside your case to check for thin spots. GS Arizona explains: “This simple little tool (bent paper clip) will let you check the inside of cases before you reload them. The thin spot will be immediately apparent as you run the clip up the inside of the case. If you’re seeing a shiny line on the outside and the clip is really hitting a thin spot inside, it’s time to retire the case.” Photo by GS Arizona.
Monitor Primer Pocket Dimensional Changes
Another case-head-area and pressure-related check is the primer pocket. As said, the primer pocket will get larger in diameter and shallower in depth each firing. As with many such things, the questions are “when” and “how much,” and the main thing, “how much?”
If the pocket gets excessively shallow, and that’s judged by a primer that seats fully but isn’t at least a tick below flush with the case base, there could be function issues. There’s a risk of a “slam-fire” with a semi-auto that uses a floating firing pin, and, if there is actual protrusion, that has the same effect as insufficient headspace. A primer pocket uniformer can reset the depth of a shallowed primer pocket to what it should be, but the real test for me is how easily the next primer seats into it. If it’s significantly less resistance, I’ll say that case is done. Shallower can be refurbished. That’s a primary function of a primer pocket uniformer. Larger diameter, though, can’t be fixed. I’ve mentioned in another article or two that, any more at least, my main gauge of load pressure has become how much primer pocket expansion there’s been.

Getting focused mentally is an important part of preparation for Perry. In 2011 I was chasing Sherri Gallagher, since then I have been chasing Brandon Green[.] If I get beat by a Service Rifle I am going to make him or her work for it. So there is your peak into my mental process. I go for the top and if I am hanging with them then the Service Rifle National Championship will come, Kind of like how I shoot for X’s and Tens will come.
