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…
Which Windflag to buy? For starters, MTM makes a simple, inexpensive flag sold on Amazon for $17.99. For more sophisticated flags CLICK HERE for Benchrest Central windflag vendors.
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.
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.
New Wind Reading App — High Power Wind Lab
There is an innovative new Wind-Reading App, the High Power Wind Lab, that can help you figure your hold-offs in all wind conditions. This is available now for iOS devices, and an Android version is coming soon. In this video, our friend F-Class John reviews this sophisticated new Wind App:
More and more folks are using Burris Signature Rings these days. These unique rings feature polymer inserts. That allows you to pre-load some elevation in your scope set-up, or you can center-up the windage. Additionally, the polymer inserts hold your scope securely without leaving marks on the tube. Lastly, some folks believe that Signature rings may offer advantages for benchrest competition. Rodney Wagner shot a world-record 600-yard group using Burris Signature Zee Rings (“Zee” denotes the Weaver-rail model). James O’Hara set multiple IBS 1000-yard records using Burris Signature Zee Rings. James will tell you he thinks “all his guns seem to shoot best with these rings”.
IBS World Record Set with Signature Zee Rings
Are Signature Zees good enough for competition? Absolutely. Some folks scoff at these Burris rings, given their modest price. A set of 1″-diameter Sig Zees cost $40.89 at Midsouth. But consider this, in 2013 Rodney Wagner shot the then-smallest 600-yard group in history, a 0.336″ 5-shot stunner, using Signature Zee Rings on his IBS Light Gun. It took five years for a smaller 600-yard group to be shot, a 0.311″ by bullet-maker Bart Sauter, using his IBS Heavy Gun. (See IBS 600-yard Records.) Here’s Rodney with his record-setting rifle, fitted with affordable Signature Zee 30mm rings.
Vendors Have Burris Signature Rings in Stock Now
Various models of Burris Signature Rings are available from many online vendors. NOTE: You may have to check with more than one seller to get the exact size, height, and model you prefer. But right now these vendors have pretty good selections of Signature Zees in stock now, including the popular 30mm High and 30mm Extra High models (each currently $56.36 at Midsouth). If you check all three sellers, you’ll probably find what you need.
From time to time, we all encounter a primer that doesn’t go off. It’s normal to attribute the problem to a bad primer. But sometimes there are other explanations. George S., one of our Forum members, experienced a couple failures to fire, but he learned that the issue was his priming TOOL, not his primers. Here’s what George told us. There’s a lesson to be learned:
“I had issues with CCI 450s when I had my first 6BR barreled. I had probably three or four out of 20 rounds that failed to fire. the primers were dented but didn’t fire. I called CCI since I had bought a case of them. The tech was decent enough but had the audacity to tell me I was not seating the primers all the way in the pocket. I proceeded to let him know I had been reloading longer than he had been alive and I knew how to seat a primer.
Turns out that I did and I didn’t! I was using the RCBS primer tool I had used for years and the primers felt just fine to me. I finally decided to check the tool and since I had a new one I took the seating pins out and measured them. The seating pin on the tool I had been using for years was shorter by a few thousandths! I then used the pin from the new primer tool and darned if the primers that didn’t seat down to the bottom of the cup.
I switched to a K&M primer tool for seating the CCI primers and have not had a problem since. It was the combination of harder cup and lack of proper seating. I did call the CCI tech back and apologized for being an idiot.”
Another Forum member witnessed a problem cause by misuse of a priming tool: “I did … see a failure to fire on a Rem 9 1/2 primer only a week ago. That was in the new Rem muzzleloader that uses a primed case to ignite the pellets. After watching the muzzleloader’s owner seat his primers, I believe that it was operator error not the primer. He was seating the primer and then squeezing the priming tool so hard that his hands hurt after a few. We got that corrected.”

The Gathering is a special event presented by Palmetto State Armory that allows gun writers and regular shooters to try out a variety of firearms and accessories. The Gathering 2024 runs March 22-23, 2024 in Clinton, SC. There will be live-fire demonstrations along with opportunities to try various products. Guns on display included firearms from SIG Sauer, Glock, Springfield Armory, Taurus and more.
The Gathering is a Firearm Range Day and Expo presented by Palmetto State Armory. The Gathering brings together the firearms community, media and public to showcase new and existing firearms, optics, and accessories. This year’s event is held at The Clinton House Plantation, a 2000-acre facility that houses 17 live-fire shooting bays, two clay courses, a 1000-yard range, and a mile-long range.
At The Gathering 2024, Silencer Central will have live-fire demonstrations suppressors. CEO of Silencer Central, Brandon Maddox notes: “We’ve reinvented the process of buying a silencer and are thrilled to showcase… our products at The Gathering[.]” Attendees will be able to purchase a silencer, have required ATF ID logged, generate their free NFA Gun Trust, and digitally sign their ATF application all at the event.
The pandemic-caused cancellation of the 2021 SHOT Show range day inspired Palmetto State Armory to launch its own Industry Range Day called The Gathering. The first Gathering was a big success in 2021. In 2022, PSA had its second Gathering which was even bigger and better — see the video above. And last year, the 2023 edition of The Gathering was held with great success. See the video below:

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.

For this St. Patrick’s Day 2024, our Sunday GunDay story features a beautiful F-Open rifle from Ireland. This was crafted a decade ago, but it’s still one of our favorites. It has a handsome thumbhole custom stock, and it boasts an unusual chambering — the .300 Blaser Magnum. This impressive rig carries its barreled action in a massive barrel block — not often found in F-Class rigs.
Here’s a very impressive F-Class project from Enda Walsh of Custom & Precision Rifles in Ireland. This rifle features a free-floated BAT Machines ‘M’ action with a Benchmark barrel chambered in .300 Blaser Magnum (300 BM). The barreled action is secured with a large barrel block. This handsome, long-wheelbase F-Class rig demonstrated some stunning accuracy at 1000 yards when it was brand new. Enda tells us: “I couldn’t wait until the rifle was fully polished before testing. I went to MNSCI (Midlands National Shooting Centre of Ireland) to shoot my new barrel block rifle. I came home with a huge smile on my face after shooting a five-shot group with 1.5″ vertical and 3″ horizontal at 1000 yards in an 8 mph wind.”

AUDIO FILE: Enda Walsh Talks about his New .300 BM Barrel Block F-Open Rifle.
Below you can see the barrel block in the handsome Padouk wood and carbon fiber stock. Enda uses high-spec epoxy layered between the barrel and the aluminum barrel block. Yes, those three “super-sized” cartridges are .300 Blaser Magnums loaded with with 230gr Berger Hybrids. The smaller cartridge is a .308 Win (with 150gr bullet), provided for comparison. This .300 BM drives the 230s at 3140 FPS.
.300 BM Runs 230-grainers at 3140 FPS!
Enda tells us: “I wanted something to beat the 300 WSM. After studying the .300 Blaser Magnum, I decided this was the [chambering] that could deliver high accuracy consistently and be able to shoot the 230gr Bergers at 3140 FPS. Using H1000 powder, they do very well but the case life is short at these speeds. We have backed them off a little and retained the accuracy and extended case life considerably.”
Enda says the 230gr Hybrids at 3140 fps drift much less in the wind than do 7mm 180gr Hybrids launched from a 7mm WSM. A quick run through JBM Ballistics for a 10 mph, full-value crosswind at 1000 yards (sea-level) tells the tale. JBM predicts 4.2 MOA horizontal deflection for the .30-caliber 230s at 3140 fps vs. 5.0 MOA for the 7mm 180s at 3050 fps. That 0.8 MOA difference represents more than 8 inches at 1000 yards. When you consider the small size of the F-Open X-Ring, you can see how the enhanced ballistics could be a game-changer in the wind.
Note the metal bag-rider “keel” on the underside of the buttstock.
Barrel Block Acts as Heat Sink
Enda needed a way to beat the heat, with this big case. He explains: “Because of the large case volume (roughly 82 grains of usable capacity) there are two issues. Firstly, throat wear, and secondly heat. To combat this I have a new reamer on order with slight alterations which will help the throat wear. To combat the heat affecting a 34″ barrel I decided to build a barrel block rifle. It was previously mounted in a standard stock, and when the barrel got too hot accuracy was an issue. The barrel block acts as a heat sink and also shortens the overhanging barrel considerably, which has greatly improved accuracy over a complete string. The block is made from aircraft grade aluminium.” As a final note, Enda wanted to thank Pacific Tool & Gauge for the special-order reamers.
More .300 Blaser Magnum F-Classers from Enda Walsh in Ireland
Here are three more .300 Blaser Magnum F-Class rifles Enda built for the 2014 European Championships at the Bisley Range in the UK. The color scheme comes from the Irish Flag.

Americans love AR-platform rifles. However, they can be maintenance-intensive, as hot gasses are directed right back into the action to operate the bolt. Because ARs have a somewhat unique (and dirty) semi-auto operating system, we think all AR owners should learn how their rifles operate — from the inside out. This feature provides an “inside look” at the AR, with X-Ray and Cutaway views created through advanced 3D computer modeling.
AR15 Functions Revealed with 3D Computer Animation
Ever wondered how the parts inside an AR15 work together? Just exactly how does the reciprocating bolt carrier feed rounds from the magazine? How do the elements in the trigger group work and reset after each shot? How does the gas system bleed gas from the barrel and operate the bolt carrier? These and other questions are answered in this eye-opening video from 45Snipers. Using “cutaway” 3D computer animation, this 5-minute video shows all features of an AR15 inside and out. This fascinating firearms animation allows the viewer to look inside the upper and lower receivers, into the bolt carrier, chamber, barrel, and magazine.
This video starts off slow and has annoying background music, but it is well worth watching if you own or shoot any AR-platform rifle. It illustrates all the key operations during the charging, loading, firing, and ejection processes. The cutaway animation shows how rounds are stripped from the magazine and then chambered. It then shows how every part of the trigger group works, and how the firing pin strikes the primer. You can even watch the bullet move down the barrel before the empty shell casing is removed from the chamber and tossed out the ejection port. Here are sample frames from the video:
How AR-Platform Rifles Work — General Introduction
To help reader understand the general operation of AR-type rifles, this video shows the control functions of an AR and how the upper and lower sections work together.
Cutaway 3D Animation of AR15/M16 Action — Watch Video
Here is an excellent “cutaway” animation by Thomas Schwenke that shows how an AR-15 functions — how the entire loading cycle works from start to finish.
AR platform rifles are semi-automatics version of the M16. These feature distinctive upper and lower receivers which can be readily separated via front and rear pins. The upper includes the barrel, handguard, forward gas tube, and bolt assembly, while the lower contains grip, trigger group, fire selector, and mag well. In addition the lower is attached to the stock which encloses the buffer assembly.
The original ArmaLite AR-15 was a select-fire, air-cooled, gas-operated, magazine-fed rifle designed by American gun manufacturer ArmaLite in 1956. It was based on Armalite’s AR-10 rifle chambered for the 7.62×51 NATO (.308 Win). In 1959, ArmaLite sold its rights to the AR-10 and AR-15 to Colt. Some key modifications were made — most notably, the charging handle was re-located from under the carrying handle to the rear of the receiver. The redesigned rifle was adopted by the U.S. military as the M16 carbine, which went into production in March 1964.

This popular video, viewed 3.6 million times on YouTube, provides a clear explanation of Minute of Angle (MOA) and how that angular measurement is used. Among novice shooters, there is much confusion over this term. In this NSSF Video, Ryan Cleckner, a former Sniper Instructor for the 1st Ranger Battalion, defines the term, “Minute of Angle” (MOA) and explains how you can adjust for windage and elevation using 1/4 or 1/8 MOA clicks on your scope. This allows you to sight-in precisely and compensate for bullet drop at various distances.
For starters, Ryan explains that, when talking about angular degrees, a “minute” is simply 1/60th. So a “Minute of Angle” is simply 1/60th of one degree of a central angle, measured either up and down (for elevation) or side to side (for windage). At 100 yards, 1 MOA equals 1.047″ on the target. This is often rounded to one inch for simplicity. Say, for example, you click up 1 MOA. That is roughly 1 inch at 100 yards, or roughly 4 inches at 400 yards, since the target area measured by 1 MOA increases in linear fashion with the distance.
More Minute of Angle (MOA) Explanatory Videos
This Gunwerks video explains that Minute of Angle subtends approximately 1″ for each 100 yards (well, 1.047″ to be more precise). That means a Minute of Angle increases in actual measured size the greater the distance of the target from the shooter.
This lengthy (24-minute) video defines Minute of Angle, and uses multiple diagrams to illustrate how MOA angular measurements works. The video also how MOA-based click values translate to point-of-impact changes at various distances.

This handsome, long-wheelbase F-Class rig demonstrated some stunning accuracy at 1000 yards when it was brand new. Enda tells us: “I couldn’t wait until the rifle was fully polished before testing. I went to
