NRA 2021 Annual Meetings & Exhibits Have Been CANCELLED

cancel cancellation NRA Convention Houston Texas Annual Meetings Exhibits 2021

Breaking News — The NRA has CANCELLED the 2021 NRA Annual Meetings & Exhibits scheduled for September 3-5, 2021 in Houston, Texas.

Here is the NRA’s official Statement:

Important Announcement: NRA Annual Meeting Cancellation
Due to concern over the safety of our NRA family and community, we regret to inform you that we have decided to cancel the 2021 Annual Meeting & Exhibits. This cancellation applies to all events and meetings that were scheduled in Houston. We will provide future notification regarding a rescheduled date for the annual Meeting of Members.

We make this difficult decision after analyzing relevant data regarding COVID-19 in Harris County, Texas. We also consulted with medical professionals, local officials, major sponsors & exhibitors, and many NRA members before arriving at this decision. The NRA Annual Meeting welcomes tens of thousands of people, and involves many events, meetings, and social gatherings. Among the highlights of our annual meeting are acres of exhibit space featuring the latest and greatest firearms, the display of countless accessories, and the offering of adventures and group gatherings that many travel hundreds, and some even thousands, of miles to experience. We realize that it would prove difficult, if not impossible, to offer the full guest experience that our NRA members deserve.

The NRA’s top priority is ensuring the health and well-being of our members, staff, sponsors, and supporters. We are mindful that NRA Annual Meeting patrons will return home to family, friends and co-workers from all over the country, so any impacts from the virus could have broader implications. Those are among the reasons why we decided to cancel our 2021 event.

We would like to thank our members, attendees, exhibitors, and staff for their understanding and support. We are grateful for the many contributions of the George R. Brown Convention Center, state and local officials, community organizers, area hotels, and countless event venues across Houston. We receive enormous support from Houston and the State of Texas – and we hope to return to the Bayou City for a full annual meeting experience.

The NRA looks forward to a Celebration of Freedom in Louisville in May 2022. In the meantime, we will support many other NRA local events and smaller gatherings – in a manner that is protective of our members and celebrates our Second Amendment freedom.

We wish continued health and safety to our entire NRA family.

Russian Guns and Ammo Imports Halted as of September 7, 2021

U.S. state department biden russian russian ammunition firearms ban import freeze

The Biden State Department has banned imports of Russian-made firearms and ammunition. Russian firearms and ammo importation will be blocked for a minimum of 12 months starting September 7, 2021. The State Department Notice states:

New sanctions imposed today under the CBW Act include:

Restrictions on the permanent imports of certain Russian firearms. New and pending permit applications for the permanent importation of firearms and ammunition manufactured or located in Russia will be subject to a policy of denial.

Action Will Harm U.S. Firearms Owners
The Gun Owners of America (GOA) criticized the action, stating it will NOT achieve its stated purpose, but will only harm American hunters, shooters, and gun owners:

“It is clear to us that the intention is not to harm Russia but rather to hinder the acquisition of firearms and ammunition by American citizens.

Once again, the Biden Administration’s actions are misplaced. Ending imports by licensed importers will not stop drug dealers, murderers, and other assorted street criminals. It will, however, harm legitimate U.S. businesses while driving up the cost of other ammunition due to more buyers chasing a smaller supply.

We recognize the devastating implications these sanctions would have on individual gun owners amidst a national ammunition shortage. We are currently exploring administrative, congressional, and legal avenues to respond to these new sanctions.”

U.S. state department biden russian russian ammunition firearms ban import freeze

Ammo Shortages Will Worsen
Dean Weingarten cautions that the new ban will lead to more ammo shortages:

“This is the second round of sanctions imposed on Russia by the United States over the Aleksey Navalny incident. The first round of sanctions did not ban the importation of Russian ammunition or firearms.

It is unclear how long supplies in the pipeline will last. The announcement is likely to rekindle the ammunition bubble for calibers commonly imported from Russia, such as 7.62×54, 7.62×39, 5.45×39, 5.56×45, and even match grade .22 ammunition.”

What You Need to Know about Powder Grain Shapes

Vihtavuori loading propellant reloading powder N133 N150 N140 N550 ball flake stick extruded perforated powders

POWDER GRAIN SHAPES — What You Need to Know

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.

Vihtavuori loading propellant reloading powder N133 N150 N140 N550 ball flake stick extruded perforated powders

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.

Wind Reading Tips from Bryan Litz and Emil Praslick III

Wind reading coaching bryan litz Ben Avery Phoenix wind video

Wind effects are complex. In trying to access wind speeds and angles, you’ll want to watch multiple indicators — mirage, dust, wind-flags, grass movement, and more. You’ll also need to be concerned about wind cycles. In the video below, Bryan Litz talks about variable wind speed along a bullet’s flight path. A respected ballistics guru, Bryan is the founder of Applied Ballistics and a designer of Berger’s Hybrid Match projectiles. He is also a past F-TR National Champion and a High Master Palma ace.

In this video, Bryan discusses how wind effects can vary in intensity at different points along the bullet’s flight path to the target. Sometimes the firing line is sheltered, and the strongest winds come into effect in the middle of the trajectory. Bryan concludes: “Wind matters everywhere … but the best thing you can do is try to get a handle on the wind [velocity and angle] where you are. That may or may not represent the wind down-range — that’s when you have to look downrange and make a judgment[.]”

Litz Competition Tip: Select your wind shooting strategy carefully. For beginners and veterans, most points are typically lost to wind. Successful shooters put a lot of thought into their approach to wind shooting. Sometimes it’s best to shoot fast and minimize the changes you’ll have to navigate. Other times it’s best to wait out a condition which may take several minutes. Develop a comfortable rest position so you have an easier time waiting when you should be waiting.

More Wind Tips from Wind Wizard Emil Praslick
In these two short videos, Emil Praslick III, former coach of the USAMU and USA National long range teams, explains how to find the wind direction and how to confirm your no-wind zero. Praslick is widely considered to be one of the best wind coaches in the USA.

When Winds Are EXTREME — Near Gale Force at Ben Avery

This video shows INSANE winds at NBRSA 100/200 Benchrest Nationals. This was filmed at the Ben Avery Range in Phoenix, AZ during the recent NBRSA 100/200 yard National Championships. Extreme to say the least. Based on what we’re seeing here, there are 20-25 mph crosswinds, with gusts to 35 mph — near Gale Force. Video by Hall-of-Fame Benchrest competitor Gene Bukys, whom we sadly lost to COVID last year. RIP Gene.

Texas gunsmith Mike Bryant reports: “This video shows the Unlimited Class 200 at the Nationals in Phoenix. I had three 10-shot groups in the low 2″ range with a 2.228″ being my big group and was glad they weren’t bigger. Thursday and Friday were the worst of the windy days. Unfortunately those were the days for the UL 200 and it was about as windy through most all of the Sporter 200.”

Excellent Wind Reading Resource

The Wind Book for Rifle Shooters covers techniques and tactics used by expert wind-readers. The authors provide a wind-reading “toolbox” for calculating wind speed, direction, deflection and drift. They explain how to read flags and mirage, record and interpret your observations, and time your shots to compensate for wind. Here are two reviews:

This is a must-have book if you are a long-range sport shooter. I compete in F-Class Open and when read it from cover to cover, it helped me understand wind reading and making accurate scope corrections. Buy this book, read it, put into practice what it tells you, you will not be disappointed. — P. Janzso

If you have one book for wind reading, this should be it. It covers how to get wind speed/direction from flags, mirage, and natural phenomenon. This is the best book for learning to read wind speed and direction. — Muddler

Air Travel with Firearms — Smart Advice by Stan Pate

tsa luggage rifle case Stan Pate Airline Travel

Savage Arms offers a series of Shooting Tips in the Savage Blog. Here is a helpful article from Team Savage Shooter Stan Pate. This covers how to ship your rifle safely, and then re-establish zero properly when the gun is reassembled after transport.

Traveling with Firearms — Important Advice

Traveling with firearms can be stressful. You must comply with multiple regulations and then trust your expensive guns to airline baggage handlers. And after arrival you’ll need to put your rifles back together and confirm the zeros. This article offers helpful travel advice from Team Savage shooter Stan Pate. Pate has traveled the globe competing with match rifles. Here he shares his tips for making trips easier on you and your firearms.

Easier Air Travel With Firearms
TSA isn’t nearly as careful with your rifles as you are. Proper storage before sending your firearm up a conveyer belt and into the belly of a plane is critical. Stan Pate spends lots of time each year traveling the skies and has devised a system for keeping his rifle safe when going to and from.

“Never travel with your firearm completely assembled,” Pate cautions. “A fully assembled firearm is much heavier than one that has been broken-down and stored. More weight creates more in-the-case movement, which can result in damage. I learned this the hard way years ago. My rifle was actually broken in half when traveling to an international competition. Record your torque settings, use those settings during reassembly and your return to zero should be no problem.”

“Be sure to check on current TSA rules and regulations before travel to be aware of any changes that may effect how you pack your rifles,” says Pate.

Rifle Reassembly and Resetting Zero
The quicker you can reestablish your zero, the quicker you can relax and stop worrying about if your rounds are going to hit their mark during competition. Pate, over the years, has developed a system for rifle reassembly and getting back to zero as quickly as possible. While his torque settings may not be the same as yours, the process can still be used.

tsa luggage rifle case Stan Pate Airline Travel

“The barreled-action goes back on the stock, and then I tighten all three receiver screws finger tight,” says Pate. “Next, I tighten the front two receiver screws down to 35-inch pounds. The rear receiver screws on this particular rifle likes 15-inch pounds. [Note: Proper torque settings will vary with your action and stock type. Most actions have TWO screws, not three.] Scope attachment comes next, and I follow manufacturer settings when tightening it down. All that’s left to do now is go zero your rifle.”

Sunday GunDay: .22 LR Conversion Kit for AR-15 Platform

.22 LR 22LR rimfire AR AR15 AR-15 conversion kit bolt magazine savings ammo ammunition

Over the past 18 months, popular ammo types, such as .223 Rem and 9mm, have been hard to find at reasonable prices. The high cost of .223 Rem centerfire ammo has driven more folks to shooting .22 LR rimfire ammo, both for fun and practice. This Sunday we look at a smart solution that allows you to shoot .22 LR ammo from your existing .223/5.56 AR-15 platform rifle. This is great because it allows low-cost training with no change in rifle balance, ergonomics, and/or optics.

The CMMG Bravo .22 LR Conversion Kit provides a replacement bolt/bolt carrier along with three 25-round magazines with special .22 LR-fitted followers and ammo slots. This allows you to shoot rimfire ammo from any AR-15 chambered for the .223 Rem (5.56×45). The CMMG Bravo has an integrated extension that fits into your current chamber. The rimfire bullet passes through this extension and then enters the barrel.

.22 LR 22LR rimfire AR AR15 AR-15 conversion kit bolt magazine savings ammo ammunition
The CMMG Bravo conversion Kit comes with blowback-operated .22 LR bolt carrier, rubber protector for bolt carrier tip, and three 25-round polymer magazines. To use, simply replace the rifle’s .223 Rem bolt and carrier with the Bravo .22 LR conversion unit and load up the included magazine(s) with rimfire ammo.

To use the CMMG Kit, simply remove the centerfire bolt/bolt carrier, and replace it with the CMMG silver colored bolt shown above. CMMG states: “For best performance use a round-style hammer as notched hammers can cause function issues.” Testers have stated that high-velocity .22 LR ammo works best, and CMMG notes that “36gr plated-nose bullets have proven to be the best choice for function.” The copper-plated bullets help reduce fouling.

Ultimate Reloader Tests CMMG .22 LR Conversion Kit

Our friend Gavin Gear of UltimateReloader.com recently tested the CMMG .22 LR AR Conversion Kit. He observed that installation was very straight-forward and the CMMG magazines worked well. He and fellow tester Travis Fox shot the unit both slow-fire and rapid-fire successfully.

Gavin and Travis found the CMMG Kit easy to install and fun to use. With an AR that can shoot both .223 Rem and .22 LR, it’s like having “two guns in one”. Travis was impressed with the ease of use: “It is so simple to change over to the CMMG .22 LR AR kit! It took me about 68 seconds the very first time I tried. Each time after that it took me about 40 seconds — it’s that simple. It takes longer to fully load one of the mags than it does to switch over from .223/5.56 to .22 LR and back.”

The AR shot very well with the higher-velocity ammo types. 100% functioning was achieved with both 40gr Federal Game Shok ammo and American Eagle High Velocity 38gr Copper-plated HP ammo. NOTE: CMMG does recommend high-velocity Copper-plated rimfire ammunition.

Maintenance Tip — After converting back to your centerfire .223 Rem (5.56), Travis says “make sure to clean the gas tube and components as .22 LR tends to run dirty”. READ Full Test on UltimateReloader.com.

CMMG Bravo Conversion Kit Gets Thumbs Up from Gavin and Travis
“Does this conversion kit get the Ultimate Reloader stamp of approval? Absolutely! In these times of ammunition/component scarcity this gives options to shooters. Finding bulk .22 LR can sometimes be easier than 223/5.56. This kit gives that option at a great price. Any chance to keep skills up and familiarize new shooters to a platform is a good thing. Basically two rifles for a lot less than another rifle.”

How to Install CMMG Bravo .22 LR Conversion Kit

The Brownells video below shows the installation process step-by-step:

In this instructional video, a Brownells gunsmith demonstrates (step by step) how to install, disassemble, clean, lubricate, and reassemble the CMMG AR-15 .22 LR Conversion Kits. Clear the rifle and make safe before you start the conversion. Separate the upper and lower, remove the standard bolt carrier group. You then install the conversion bolt and connect the upper and lower as normal.

Details of CMMG .22 LR Conversion Kit

.22 LR 22LR rimfire AR AR15 AR-15 conversion kit bolt magazine savings ammo ammunition

“For years I’ve had a CMMG conversion kit. It’s a drop-in system that’s … very reliable and it’s accurate. The [CMMG conversion] has lower recoil [and is] great for training. Even though ammo prices have gone through the roof, .22 LR is still cheaper to shoot than anything else.” — SootchGear

.22 LR 22LR rimfire AR AR15 AR-15 conversion kit bolt magazine savings ammo ammunition

This SootchGear video shows how to install the CMMG Bravo unit. The video also compares the original CMMG .22 LR bolt assembly with the latest integrated CMMG Bravo at 2:00-3:50. The older unit had a brass adapter and separate chamber insert. The host also tests a CMMG-equipped AR with various types of ammo. Watch a rapid-fire sequence starting at 1:48 time-mark.

Field Test with Two ARs — Rapid Fire .22 LR Testing

.22 LR 22LR rimfire AR AR15 AR-15 conversion kit bolt magazine savings ammo ammunition

The video below demonstrates rapid-fire .22 LR performance with two different ARs using CCI Mini-Mag ammo. The CMMG conversion is fast and easy: “In a matter of seconds you go from 5.56 to .22 LR”. Watch rapid-fire at 5:40 with CCI Mini-Mags in red/black rifle. Then the tester shoots a variety of ammo in a .223 Wylde-chambered all-black AR, starting at 9:40. The Mini-Mags worked flawlessly, but there were a couple fail-to-cycle sequences in extreme rapid-fire with cheaper “bulk” ammo. The lesson here is use good quality, high-velocity ammo.


NOTE: This 2018 video shows an earlier CMMG .22 LR conversion bolt that features a brass adapter and separate chamber insert. The current CMMG Kit has unitized bolt without a separate adapter or insert.

Interestingly, the Mini-Mag .22 LR ammo shot fine in the .223 Wylde-chambered AR. However, CMMG cautions: “Since .223 WYLDE is NOT a mil-spec chamber, we cannot guarantee fit or function with our 22LR conversion kits.”

Reviews from CMMG Bravo .22 LR Rimfire Conversion Kit Purchasers:

“Get it. Bought this for my Rock River AR. Bolt system goes in [easily] and fits perfectly. Took it to the range and put over 150 rounds through, only failing to feed/fire two rounds. I most definitely recommend this product to anyone looking to shoot their standard AR-15 .223 rifle on a budget.” — Pew P.

“I got this just yesterday and in two days time I have put a couple thousand rounds through it and no hick-ups. I have no complaints.” — Seth

“Best buy for anyone during this ammo crisis. Ammo is extremely expensive and hard to find. It was a ‘no-brainer’ once I found this kit. Ran 200 rounds to break it in for about $20 and had maybe 3 failures. Accurate up to 50 yards (I haven’t tried further) without optic adjustments.” — Joshua M.

“Purchased one of these in January. Took it to the range shortly after for my daughters to try out. We have three ARs and this thing functioned flawlessly. We practiced swapping out the 5.56 carrier with this back and forth, flawless. Enjoyed it so much now I’m purchasing another one.” — J.B.

“Great product. I bought this due to the high cost of ammo. I wanted to still shoot my AR and this was an alternative. This thing works great… works flawless with different types of .22 LR, from premium CCI to the cheap stuff. I recommend this to anyone thinking about getting one.” — Thom

Giant 14.5x114mm Cartridge Dwarfs .338 Lapua Magnum

14.5x114 mm cartridge Russia South Africa
Photo courtesy Elardus de Lang, Truvelo Manufacturers Armoury, South Africa.

Believe it or not, here is a cartridge that makes a .338 Lapua Magnum look like a toy. The 14.5x114mm cartridge was designed as a MG and rifle-fired anti-materiel round. To translate from the metric system to caliber and inches, the round is a mammoth .57 caliber which measures 4.49 inches to the case mouth, and 6.13 inches overall. That jumbo-sized case holds a whopping 655 grains of powder. Commonly-loaded projectiles weigh 920-1030 grains. The 993gr armor-piercing projectile has a muzzle velocity of approximately 1006 meters per second (3300 fps) and can penetrate 30-32 millimeters of RHA steel at a range of 500 meters.

The top photo comes from Elardus De Lang, a Forum member who works at the Truvelo Manufacturers Armoury in South Africa. Elardus also provided an impressive video showing the massive 14.5x114mm being shot from prone with a Truvelo-built bolt-action rifle. Elardus tells us: “Here is a video, with a slow-motion ending, of our 14.5x114mm anti-materiel rifle being fired in our indoor testing facility. This caliber is a true beast! It propels a 993gr Armor-Piercing Incendiary bullet to 3300 fps, burning 480 grains of powder in the process. [This shows] that rifles of that power level can actually be shootable. The concussion indoors is something to experience……every shot feels like you are being punched in the face, and the heat from the muzzle flash actually hits you like a wave!”

14.5x114mm Cartridge Design and Dimensions
The 14.5×114mm has 42.53 ml (655 grains H2O) cartridge case capacity. The exterior shape of the case was designed to promote reliable case feeding and extraction in bolt action rifles and machine guns alike, under extreme conditions. Cartridges typically use lacquered steel cases, but some countries also use brass cases for the 14.5x115mm.

All dimensions are in millimeters (mm). Americans would define the shoulder angle at alpha/2, or 22.5 degrees. The common rifling twist rate for this cartridge is 455 mm (1:17.91″) with eight lands/grooves. According to official guidelines, the 14.5×114mm can handle up to 360 MPa (52,213 psi) piezo pressure.

14.5x114mm Cartridge History
The 14.5×114mm (.57 Cal) is a heavy machine gun and anti-materiel rifle cartridge used by the Soviet Union, the former Warsaw Pact, modern Russia, and other countries. It was originally developed for the PTRS and PTRD anti-tank rifles, but was later used as the basis for the KPV heavy machine gun that formed the basis of the ZPU series anti-aircraft guns that is also the main armament of the BTR series of armoured personnel carriers from the BTR-60 to the BTR-80 and for heavy anti-material sniper rifles. The cartridge was designed in 1939 and first issued in 1941.

Tiered “Bleacher Blocks” Work Well for Many Reloading Tasks

Lyman Bleacher Block stepped cartridge holder

Here’s an inexpensive product that can make your case prep and loading tasks easier. We use and recommend the cleverly-designed Lyman Bleacher Blocks. These multi-level (stepped) cartridge holders save space on your bench AND make it easier to select a particular case/cartridge from a full block. Each row is a different height for convenience. With Bleacher Blocks it’s also easier to check for powder levels, or place bullets before the seating process.

Lyman’s Bleacher Block cartridge holders have many advantages over conventional, single-level blocks. Use the different levels for sorting brass. Or, migrate the brass from top to bottom as you proceed through case prep stages. If you are assembling loads with different bullets for load testing, you could arrange the loaded rounds on different levels for easy recognition. For example put V-Max loaded rounds on the top tier, and Berger Hybrid loaded rounds on the bottom tier. Or, if you are experimenting with neck tension, you can use different rows for cases processed with different bushings.

Made of durable orange polymer, Lyman Bleacher Blocks are molded in three sizes. The smallest size (with 0.388″-diam holes) fits .223 Rem-size case heads. The middle size (with 0.485″-diam holes) fits .308 Win-size case heads. That works for 6mmBR/Dasher sized cases perfectly. The biggest Bleacher Block has 0.565″-diameter recesses for magnum-size cases. All three cartridge block sizes hold fifty (50) rounds. Purchase any size for just $6.37 per Block at Midsouth.

Lyman Bleacher Block stepped cartridge holder

Here’s what Lyman says about its innovative cartridge block design: “Our [stepped] loading blocks allow for easier handling of cases in and out of the loading block. Our stepped design allows you to easily grip a single case without jamming your fingers down into a group of cases like in traditional loading blocks, and allows for a smaller ‘footprint’ on your bench.”

Lyman Bleacher Blocks are among the Reloading Tools reviewed in this helpful video:

NRA High Power long range national championship palma oliver milanovic Eliseo tubegunMilanovic Wins LR National Championship
We have a new Long-Range National Champion. Competing at Camp Atterbury in Indiana, Oliver Milanovic took the 2021 NRA National Long Range Championship with a score of 1245-73X. Oliver was shooting an Eliseo Chassis + Borden Action Palma Rifle with 155gr bullets. Finishing second, tied on points but with four fewer Xs, was 2019 National Long Range Champion SSG Amanda Elsenbuss, with 1245-69X. In third place was Jeffrey Miles, just one point back, with 1244-73X.

As you can see, with the top three shooters all separated by just one point, it was a very close competition. But Milanovic, a popular marksman from Arizona, put on an impressive performance to take the win and the Thompkins Trophy. No stranger to the podium, Oliver has been on the winning Sling Division Team at the Berger SW Nationals in the past.

For all the relays, Milanovic shot his trusty .308 Winchester Competition Machine (Eliseo) chassis rifle with a Borden action, loading Palma-spec 155-gr bullets. In the Long Range Championship, other chamberings are allowed for some stages, but we’re told Oliver ran his 155gr Palma load throughout. Milanovic also won the Palma Individual Trophy Match with an impressive 450-30X score, not dropping a single point.

How to Install and Adjust Competition Rifle Slings

Dennis DeMille Creedmoor Sports Rifle Sling video training set-up
Dennis DeMille shows a young competitor at the CMP Western Games how to adjust his leather sling.

The NRA High Power Over-the-Course (OTC) National Championship will be held at Camp Atterbury over the next 7 days. Firing will be done in multiple positions — prone, sitting/kneeling, and standing. Proper support and adjustment of the sling is vital for successful High Power competition. In this short article, Dennis DeMille, a past Service Rifle Champion, explains how to set-up a sling on match rifles.

Setting-Up a Leather Service Rifle Sling for Competition
So you made the mistake of disassembling your leather service rifle sling, or are intimidated about how to use one? In this Creedmoor Sports InfoZone video, Dennis DeMille (past Creedmoor G.M.) explains how to set up and use a sling. The covers the basics — Dennis starts with a totally disassembled leather service rifle sling and shows you how to set it up properly.

Tip: “Many shooters shy away from using a leather sling because they have never been taught how to use one. That’s unfortunate. In my opinion a leather sling offers more support than a web sling, which is important when competiting with the heavier than normal rifles.”

Configuring the Sling for the Standing (Offhand) Position
In this second in a series of Creedmoor InfoZone videos on the setup and use of the leather service rifle sling, Dennis DeMille details how to configure and best utilize the leather service rifle sling while shooting from the standing position.

Tip: “Putting the Frogs in different hole will change the amount of added elevation a sling provides.”

Looking at Sling Types — Comparing the Features
In this video Dennis showcases a large variety of shooting slings. He explains the strong points of each type so you can choose the sling best suited to your discipline and shooting style.

Dennis DeMille High PowerThe Benefits of Dry-Fire Training
Once you know how to set up your sling properly, you’ll want to practice. Dennis DeMille stresses the importance of dry-fire practice with sling and shooting coat. Dry-Fire training is essential to the sling disciplines. Dennis DeMille, a national Service Rifle Champion, told us that, for every minute he spent in actual competition, he would spend hours practicing without ammunition. While in the USMC, Dennis would practice in the barracks, working on his hold and dry-firing:

“The most important thing is to spend time off the range practicing. Most of what I learned as a High Power shooter I learned without ammunition — just spending time dry firing and doing holding exercises. Holding exercises will really identify the weak parts of your position. The primary purpose of dry firing is to get you used to shooting an empty rifle. If you can shoot a loaded rifle the same way you shoot an empty rifle then eventually you will become a High Master.”

“Can Do” — How Modern Suppressors Are Made — Step by Step

Silencerco suppressor factory video production metal fabrication can silencer baffle
Image from SilencerShop.com Octane 45 HD suppressor review. SWR is now a part of SilencerCo.

Here is a cool video that shows the entire production process for a SilencerCo Octane pistol suppressor start to finish. Beginning with the raw materials, this video shows a wide variety of cutting, milling, drilling, burnishing, fitting, metal bathing, surface finishing, and laser etching processes.

If you have any interest in production methods you’ll want to watch this video all the way through, and maybe a second time.

SilencerCo states: “From cutting metal to chemical baths, to extensive quality control every step of the way, our streamlined process is more than just a few steps.” We think you may be surprised by how many steps are involved in producing this silencer (aka “suppressor”).

The Octane is a user-maintainable, multi-caliber centerfire pistol silencer featuring a modular mounting system for use across a wide range of hosts. High strength, stainless steel CTA™ (Click Together Assembly) baffles are easily disassembled for cleaning. This design makes the Octane one of the most durable small-caliber suppressors on the market.

In its Octane 45 review, SilencerShop notes: “When it comes to ease of maintenance, the Octane 45 is probably the simplest .45 suppressor on the market. It uses the new click-together baffle system from Silencerco/SWR – which allows the suppressor to come apart like a monocore suppressor, while providing performance that is closer to a K-Baffle design.””

Store Your Cleaning Rods with Handy Fishing Rod Racks

Fishing Rod Rack Cleaning RodsForum member Nodak7mm has discovered an ideal way to store your rifle cleaning rods in your garage or loading room. Using inexpensive Berkley Horizontal Fishing Rod Racks, Nodak7mm has secured a half-dozen Dewey rods on the back of a door. You could also mount the racks along a wall or on the side of a storage cabinet. This installation takes up minimal space and the Berkley Racks cost just $11.22 at Amazon (select “6 Rod Rack”) or $11.64 per set at Walmart. If you prefer wood, Amazon also sells a pine 6-rod wall rack for $22.45.

Nodak7mm explains: “I was moving some fishing poles around and ended up with an extra pair of Fishing Rod wall racks. I said to myself, ‘I bet this would hold my Dewey cleaning rods’. I mounted the pair on the inside of a closet door in my man cave and put my cleaning rods in it. It works like a charm and is far cheaper than a specially-made rack that only lets the rods hang. One can even slam the door with the rods mounted and they stay put. This rod rack set… is made by a nationally recognized name and does a great job of holding the cleaning rods securely and safely.” These are inexpensive and are easy to mount to a door or wood cabinet.

Stow Your Cleaning Rods on Your Gun Safe
Another option is to make a rod set with a magnetic backing strip. This can be affixed to the sides of your gun safe or steel storage cabinet. Here is a home-made, magnet-affixed cleaning rod holder made by Forum Member “BobM”. This smart installation works great. CLICK HERE for more information.

Palma Competition — by John Parker, Shooting Sports USA

According to the NRA High Power Rules 3.3.1 (a), a Palma rifle is “a rifle with metallic sights chambered for the .308/7.62 or .223/5.56 NATO cartridge case”.

When talking about Palma rifle competition, the traditional course of fire is at three yardages, 800, 900 and 1000 yards. The first Palma match was conducted by the NRA in 1875 at New York’s Creedmoor Range. The original Palma trophy, now lost to the ages, was commissioned by none other than Tiffanys. SEE 2018 SSUSA Camp Atterbury Long Range Gallery HERE.

3D Cutaway Animations Reveal How AR15 Rifles Work

ar-15 AR15 3D animation video youtube cutaway 5.56 AR .233 Rem

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.

Verify Scope Clicks and Tracking with B2B Precision Targets

Box 2 Bench Precision B2B target dots Milrad Mil Scope checking target

Wouldn’t it be great if you could put up one BIG target that would handle a myriad of important tasks at the range: Zeroing, Load Development, Click Value Verification, and Click Tracking Repeatability Tests. Well the team at Box to Bench Precision (B2B) has developed what may be the most versatile (and biggest) precision targets ever developed. With ultra-accurate grid geometry, and razor-sharp printing, B2B’s targets set a new standard for target precision.

Click Tracking Grid Target
B2B box bench precision targetsThe best procedure for checked the true value of your scope click values is to use a tall target that can dial in at least 25 MOA of “up”, and check where your cross-hairs air compared to exact pre-measured reference lins. B2B developed an advanced target just for that task. The 30″ tall by 23.5″ wide Rex Grid Target (shown below) provides a highly precise grid for testing elevation and windage clicks. The unique grid design has small tics denoting 1/4 MOA, 1/2 MOA, and 3/4 MOA. 1 MOA is marked with a “+” and the 5, 10, 15, 20, & 25 MOA elevation lines are bolded for better visibility. There are aiming points at 5 MOA intervals over the full grid.

Box 2 Bench Precision B2B target dots Milrad Mil Scope checking target

This same target can also be used for “Box Tests” that verify click values and repeatability. with a box test you start in one corner with the initial shot (we recommend doing this with a warm barrel after a couple foulers). They you add “up” clicks to go straight up and take a second shot. Next add horizontal clicks to go across for the third shot. Then click down (the same number of cliks you went up) for the fourth shot. As a last step you reverse your horizontal clicks and take a fifth shot. If you have a good rifle and the scope clicks are repeatable, your fifth and final shot will be touching the first shot.

B2D’s Rex Grid Target can be used for Box Tests, as can B2B’s popularhttps://bit.ly/2BBe1jYLoad Development and Scope Tracking Target (left below) and B2B’s Sniper’s Hide 100-yard Target (right below).

B2B box bench precision targetsB2B box bench precision targets

B2B’s 100 Yard Long Range Load Development and Scope Tracking Target will perform many functions. This big, 30″ x 23.5″ target has specific aiming points for various tasks. In the upper left, there are 11 small orange circles for precision load testing. Over on the upper right are 7 more small, orange circles for doing a Seating Depth Comparison test.

The bottom half of the target has larger black-on-white circles that serve multiple functions. Use the corner circles to do a “Box Test” to confirm scope tracking. There’s another great feature on this target — running up the center of the target is a tall line that shows elevation in both MILs and MOA. That helps you confirm the TRUE click values of your optic. You’d be surprised how many scopes are slightly off — not exactly 1/4 MOA, 1/8 MOA, or 1/10 Mil as advertised. That’s why Long Range shooters absolutely need to verify their click values.

Buyers Praise the B2B Targets
We’ve handled the B2B Targets, which are printed on high-quality, tear-resistant card stock. We can attest the printing is very precise — with accurate elevation and windage values. These aren’t your ordinary targets — they are LARGE — nearly three feet tall. Verified buyers praise these targets:

“Thank you for talking to me about the MIL and MOA markers on your targets. They are very accurate. While using the Long Range 100-Yard Load Development/Scope Tracking target and my new scope, it helped me realize that my scope wasn’t tracking correctly (both turrets). So, I sent the scope to the manufacturer. When it came back, and using your target as my known constant… the scope is now ‘spot-on’ accurate. These targets are a great tool to gain a better understanding of your rifle, scope, turrets etc., all on one sheet.” — Stan, 2018

“Almost too nice to put holes in. I was in the printing industry for 35 years and these are really well done. Quality paper and precise printing … able to see bullet holes easily with these!” — Dan, 2018
