+ONE Program to Encourage New Shooters
August is National Shooting Sports Month. As part of this effort, the NSSF encourages firearms owners to take one novice to the range this month. This +ONE Movement will help strengthen the ranks of shooters, which, in turn, can help protect our Second Amendment freedoms. The NSSF states: “If just one in three of America’s recreational shooters adds one new person to the shooting sports, we’ll secure a strong future for generations to come. So be the one. For all the thrills and excitement recreational shooting has given you, join the +ONE movement and invite someone to the range today. Share your experience on social media.”
The +ONE campaign seeks to build the ranks of shooters. The NSSF says: “If just one in three of America’s recreational shooters adds one new person to the shooting sports, we’ll secure a strong future for generations to come.” Learn more at LetsGoShooting.org.
As part of the +ONE Movement, the NSSF encourages all participants to practice gun safety and proper firearms handling and storage practices. This video covers basic gun safety procedures:
SHARE THESE 10 SAFETY TIPS WITH +ONE INVITEES
The NSSF has created a list of TEN Rules of Firearms Safety. While you’re at the shooting range or anywhere you handle a firearm, safety ALWAYS comes first. Here are the 10 Key Rules of Firearms Safety. NOTE: The first four rules are the most important.
Gorgeous wood stock crafted by Joel Russo: “A customer from Texas commissioned me to make him a one-of-a-kind stock, so I pulled a slab out of inventory, and put it all together.”
One of the most popular items in our Shooters’ Forum is the ongoing “Pride and Joy” thread. Since 2009, Forum members have posted photos and descriptions of their most prized firearms. Here are some notable “Pride and Joy” rifles (and one wheelgun) showcased in our Forum. Do you have a gun you’d like to see featured there? Register for the Forum and you can add your favorite gun to the list.
This 22 BR Savage, with upgrades from Sharpshooter Supply, is the “pride and joy” of Forum member Maynard. Note the heavy-contour custom barrel with brake. That 22 BR cartridge is a very effective choice for varmint work, as the ground hog in the photo proves. The 22 BR and 22 Dasher are capable of outstanding accuracy with a large variety of bullets and powders. A 22 Dasher can rival the ballistics of a 6mmBR out to 500+ yards, but with reduced recoil.
Above is a nice field rifle built up by a father for his daughter. Forum member FrankZ explains: “This is my favorite rifle and it will become my daughter’s first centerfire. The action is from the first rifle I purchased with my own money 21 years ago (700VSS).” The rifle now sports a 24″ Brux barrel chambered in 6mm Creedmoor, with aftermarket PT&G Bolt and DBM metal.
This handsome 30BR competition rifle was crafted by its owner, Forum member WillyTP who runs Todd Payseur Stocks in South Carolina. He posted: “Finally found the time to make myself a new stock and get it finished this time. All work from the rooter to the tooter by yours truly.” This score benchrest rifle features top-end components: BAT SV action, BRUX Barrel, Bix’N Andy trigger, and Nightforce 42x44mm scope.
Here is a 6BR Ackley Improved built by Alex Wheeler. This blue marble-painted beauty features a BAT “B” action timed by Alex, fitted with Jewell trigger, and Borden trigger guard. The barrel is a Hawk Hill HV contour finished at 28 inches. The stock is a Deep Creek Tracker with 4″ forearm and rudder system (the toe of the stock adjusts for angle, allowing better tracking). This scope is a Vortex 15-60x52mm Golden Eagle riding in Burris Signature Zee rings.
Forum member Grimstod posted this nice 6BRX in a scenic setting: “Bill Goad at Premier Accuracy crated this fantastic 6BRX. It shoots better then I do.” The rifle features a single-feed Alpin action, with Hart 26″ 1:8″-twist barrel, chambered for the 6BRX (6mmBR wildcat) with .269 neck. Grimstod currently runs 95gr Berger VLDs in Lapua brass. On top is a Leupold 40x45mm scope on a Picatinny rail that Grimstod machined himself. The stock is an HS Precision painted by Premier Accuracy.
Here’s a gorgeous green 6mm Dasher. Forum Member Gunnermhr states: “This is my new 12-lb Dasher for the 1000 Yard Benchrest silhouette matches. My good friend at CRS Custom Rifle Stocks in Aaronsburg, PA made and painted the stock. It’s similar to a Tooley MBR with a few modifications. It still supported on a 3″ forearm and is full length. Hard to imagine it still makes weight with a wood stock and a 36 power Leopold. Crossed the scale at 11.7lbs. The rifle features a BAT “B” Action. The paint is Candy Apple Green, the forearm has a white base-coat, center section is gray base coat and the buttstock is black base coat, all covered with five coats of clear. It’s the new pride of the fleet as it shoots as good as it looks. This gun hammers with 105gr Berger Hybrids.”
Here’s a state-of-the-art Benchrest rifle, finished proudly in bright red. Forum Member JimmyMac posted: “Picked up my new 6 PPC today. This red rig features a Borden B action (Jewell trigger) fitted with a Lederer 1:14″-twist barrel with a Loker tuner. The barrel action rides in a Roy Hunter stock. On top is a Nightforce 42x44mm Competition scope in BAT rights. The rifle was smithed by Dave Bruno.
This impressive rifle features an “antique” 1917 Enfield action chambered for the .338 Win Magnum cartridge. The lovely Maple stock was hand-carved by Forum member Spitfire_ER. He tells us: “I found this piece of wood as a return at a lumber yard about 7-8 years ago. I asked the guy in the yard about it and he said it had been returned because it had too much figure for the job the customer was working on. First thing I thought was, ‘That would make a nice stock’.”
Not a Rifle But Still a Stunner…
Last but not least is one of the nicest stainless Ruger revolvers we’ve ever seen. Forum member Longcarbine says: “This is not a rifle, but it’s my favorite weapon”. The Ruger is fitted with a custom Picatinny scope rail with matching silver-tone Bushnell Trophy handgun scope, plus handsome faux Ivory grips. This wheelgun is almost too pretty to hunt with…
Our friend Gavin Gear has crafted an excellent video showing how to make a threaded Modified Case for use with the Hornady Lock-N-Load Overall Length Gauge. You can watch Gavin make a Modified Case start to finish in the video below:
Video Shows How to Drill and Tap Modified Case
Gavin has some clever tricks. First he uses a sizing die to hold the cartridge case during the threading process. Second he uses two drill bits in sequence — a smaller bit to ream out the primer pocket, and then a larger “M” bit to increase the hole diameter before threading the brass. Finally he leaves the threading tap IN the brass, locks the tailstock, and then “gently pulls on the quill” to remove the brass from the die held in his lathe (See 5:46 timemark).
Get the Correct 5/16″-36 RH Tap
Unfortunately, Hornady has selected an uncommon thread type for OAL Gauges. You probably won’t be able to buy the correct 5/16″ – 36 RH HSS Tap at your local hardware store. However you CAN order this special tap from Amazon for $9.99.
Modified Case Q & A — TECH TIPS
Why do I need a Modified Case?
Every serious reloader should have a Modified Case for each cartridge type they shoot. The reason is that this allows you to get very precise measurements of the length-to-lands in your chamber. When used with the Hornady OAL Gauge, with some practice, you should be able to get repeatable length-to-lands measurements within about 0.0015″. We generally do 4-5 measurements with the OAL Gauge and usually 3 or 4 will be “on the money”. NOTE: We recommend a gentle, easy pressure on the plastic pusher rod. Don’t push too hard or you will jam the bullet hard into the lands, which produces inconsistent results.
Can’t I Just Buy a Modified Case?
Hornady makes a variety of Modified Cases sold on Amazon and through retailers such as Midsouth. While Hornady makes modified cases for many standard cartridges, if you shoot a wildcat such as the 6mm Dasher or .284 Shehane, you’ll need to create a custom modified case. And even if you shoot a standard cartridge such as the .308 Win, you can get more consistent measurements with a custom Modified Case.
If you do decide to make your own modified case, you’ll want to start with a case that’s been fired in your rifle. That way you get the best fit to YOUR chamber. Also, you won’t need to expand the neck to provide bullet clearance. Then you need to drill out the primer pocket and tap the base of the case to match the threads on the Hornady OAL Gauge tool. Make at least two modified cases, as you’ll probably misplace one at some point.
MORE INFORMATION: Want to learn more? We published a much longer story in which Erik Cortina explains in greater detail how to made the Modified Case. That article illustrates the 5/16″ – 36 RH HSS Tap required and shows how to set up the lathe to drill and tap your case. If you are serious about making your own Modified Cases, you should Read the Full Article.
A while back our Aussie friend Stuart Elliot of BRT Shooters Supply filmed some interesting videos at the QTS range in Brisbane, Australia. Stuart told us: “I was shooting in an Air Gun Benchrest match here in Brisbane, Australia. I finished my target early and was awaiting the cease fire and took a short, slow-motion video of windflag behavior.” You may be surprised by the velocity changes and angle swings that occur, even over a relatively short distance (just 25 meters from bench to target).
Here are windflags in slow motion:
The flags show in the videos are “Aussie Wind Flags”, developed by Stuart Elliot. These are still produced in Australia, and are now available through BRTFlags.com.
Here is a video in real time:
Stuart says this video may surprise some shooters who don’t use windflags: “Many people say the wind doesn’t matter. Well it sure does — whether for an airgun at 25 meters or a long range centerfire at 1,000.” This video illustrates how much the wind can change direction and velocity even in a small area.
Sometimes you have an opportunity to go shooting but you’re a long way from home and don’t have your regular tall target frame(s). Here’s a handy product — a 28″ tall foldable cardboard cone — you can easily carry in your vehicle and deploy any time.
With this innovative Target Cone you can easily carry a target-holder wherever you go. The Target Cone from Re-Nine Safety transports flat so it can be easily stowed in the trunk of your car (or even under a seat). When you’re ready to use it, simply fold the flaps to create a self-supporting cone with pre-printed targets on one side. Place a rock on the base to hold it steady. The Target Cone can be used by itself or, as shown below, you can attach other targets, such as Re-Nine’s Silhouette Target (below right).
We think this is a great innovation. Keep a couple Target Cone flats in the back of your car or truck and you’ll always have a target support. For spur-of-the-moment range sessions, this is much easier than toting around a big target frame. The Re-Nine Safety Target Cones come flat, fold together and interlock forming a sturdy 28″ tall stand-alone target. These are sold as a 5-pack for $25.00.
Today, August 2, 2026, classic military rifles will fill the firing lines at Camp Perry. Multiple vintage rifle competitions have been running this weekend. The National John C. Garand, Springfield, Vintage and Modern Military Match (GSMM) ran on August 1st, while today the M14 Heritage Mage and Vintage Sniper Rifle matches run at the Viale Range at Camp Perry. (See CMP Camp Perry 2026 Calendar.) Some participants are shooting just one rifle type, but there was also a combined GSMM 4-Gun Aggregate. This GSSM Agg encompasses a series of position shooting matches on NRA SR targets at the CMP Nationals. Match scores will be posted on the CMP National Matches Results Page.

The annual GSMM event is one of the most popular events at Camp Perry, drawing participants from around the nation. One of America’s top GSSM shooters is Brian Williams, who was profiled in our Daily Bulletin. The 4-gun Aggregate includes Garand, 1903 Springfield/1917 Enfield (or similar bolt rifle), M1 Carbine, and AR-type rifle for “Modern Military”. Remarkably, Brian won the GSMM 4-Gun at the CMP National Matches in Camp Perry three years in a row — the inaugural 2017 4-Gun Agg, plus 2018 and 2019. Below, Brian offers some thoughts on the classic wood-stocked rifles used in GSMM competition: M1 Garand, 1903 Springfield, and M1 Carbine.
M1 Garand Service and Maintenance
Shooting Sports USA (SSUSA) published an excellent article on Service and Maintenance of M1 Garand Rifles. This offers some smart tricks, such as using smoke from burning masking tape to darken the front sight post. There is also an older SSUSA article that covers basic cleaning and servicing and also explains how to upgrade the performance of your Garands. READ Article HERE.

This Brownells video shows how to disassemble your M1 Garand.
Recommended M1 Garand Service Manuals
Among the many M1 Garand manuals available, we recommend the CMP’s U.S. Rifle, Caliber .30, M1: ‘Read This First’ Manual. This booklet covers take-down, reassembly, cleaning, lubrication, and operation. The manual comes with CMP rifles or can be purchased for $3.25 from the CMP eStore. The author of Garand Tips & Tricks says: “It’s one of the best firearms manuals I’ve seen and I highly recommend it.”
The Classic Wood Guns of CMP 4-Gun Competition
Perspectives on M1 Garand, M1903A3, M1917, and M1 Carbine
CMP 4-Gun ace Brian Williams provides perspectives on the “Wood Gun” game, with suggestions on how to improve your performance with the M1 Garand, M1903 Springfield, M1917 Enfield, M1 Carbine, and other 20th Century military rifles. Brian explains what to look for…
Q: What should one look for when acquiring older rifles for CMP 4-Gun Games — M1 Garand, M1903/1903A3, M1917, M1 Carbine? What are realistic budgets for these firearms? What kind of accuracy can one expect? What upgrades are important?
Brian: All of these military surplus rifles are out there, but they are getting harder to get your hands on. And, just like everything else, the prices continue to rise. Not that long ago you could get your hands on a M1 Garand for four or five hundred dollars. In today’s market they are usually about double that price. But understand that these rifles are all unique and all have a story to tell. No two are alike, or have the same story. Just like the guns themselves, there are fewer and fewer dedicated gunsmiths for these vintage rifles. But I promise if you look for a good smith, they are out there and they are some of the most interesting people you will ever meet.
M1 Garand — Of the four (4) centerfire guns I shoot in the CMP games, my favorite has to be the M1 Garand. There were over 6 million of them produced in a very short time period, and every single one has its own unique story, and that is just cool. M1 Garands are capable of good accuracy. I believe that a well-maintained M1 with at least a replacement barrel is capable of shooting between 1 and 1.5 MOA.
M1903A3 Springfield — I find that the sights on a M1903A3 are a little easier to see than the sights of the M1903, but both are very accurate rifles. Like most military rifles in the current climate the prices have risen dramatically, but there are some gems out there that can be had for far less than $1000. The nice thing about the Springfield rifle is that almost all of the accuracy than you would want can come from just replacing a worn out 80-year-old barrel. In terms of accuracy, I think a good M1903A3 can shoot 1 MOA most of the time.
M1917 Enfield — This rifle is the newest of my collection and it shoots very well, with just a new Criterion barrel — again about 1 MOA with iron sights. These rifles are very close in price to the M1903 Springfield. But if you do your homework and keep your eyes open, there are always great deals to be found. I actually prefer shooting the M1917 to my M1903A3, due primarily to the M1917’s cock-on-close bolt which allows smoother cycling.

M1 Carbine — By 1945 there had been more M1 Carbines built than Garands. Today the Carbine can be harder to find, and due to the scarcity the price has shot up and most military M1 Carbines are going for more than $1000 at this point. The great thing about the M1 Carbine is that as long as you have a good ammo supply this rifle can shoot. Honest. I have had countless numbers of people that tell me that there is not an M1 carbine that will shoot. I can tell you from experience that they will, but you are going to have to put in some time with one to learn how to get it to shoot where you want it.
The M1 Carbine shoots the .30 Carbine round, with 110gr bullet going about 1990 FPS. In comparison, the .30-06 Springfield round used in the M1 Garand is almost three times more powerful than the .30 Carbine.

The prone position (with sling) shown by two talented Service Rifle shooters. At top is Brandon Green, a multi-time U.S. National Highpower and Long Range Champion, who has also won the prestigious King’s Prize in the UK. Below is Tony Chow, a gifted match shooter. NOTE: Current Service Rifle rules allow the use of optics up to 4.5X.
Jay Christopherson, 2024 and 2020 Southwest Nationals F-Open Champion, is one of the nation’s best F-Class shooters. When shooting F-Class, Jay uses a SEB Mini front rest and a large rear sandbag to support his big 22-lb F-Open rifle. Though he loves F-Class, Jay has also been interested in Service Rifle competition where no external supports are allowed. When shooting Service Rifle you hold the rifle with your arms and a sling. Some Service Rifle competitions involve three position (Standing, kneeling/sitting, and prone), while others are prone only. Even in the prone position, the sling is a vital accessory. The USAMU video below shows how to rig your sling properly for use in the prone position.
Improving Prone Shooting with Help from Emil Praslick III
Jay dramatically improved his Service Rifle “hard-holding” technique by enlisting the help of Emil Praslick III, former U.S. Army Marksmanship Unit (USAMU) rifle coach. Emil’s guidance and advice resulted in an immediate increase in Jay’s scores on target, as recorded by his ShotMarker electronic target system. Jay noted: “These targets show the difference between hacking it on your own, and spending an hour with someone who knows what they are doing and can tell you that you are doing it wrong.” These targets show Jay’s “before and after” Service Rifle results shooting slung up prone at 600 yards:
Service Rifle, Prone with Sling at 600 Yards
Here is Jay’s target BEFORE training with Emil Praslick — a 194-3X with lots of vertical.
And here is Jay’s improved target AFTER putting Praslick’s advice to work — impressive 199-8X with significantly less vertical.
You can see on this second target much improved vertical. All 20 shots were in a vertical range much smaller than the vertical height of the 10-Ring. Had shot 16 not gone wide left, this would have been a 200. Shot 16 was OUT of the 10-Ring to the left, but note that vertically it has almost perfect elevation.
Jay stated: “I was pretty amazed at not only the difference on the target, but how much difference the changes Emil suggested made to how my hold felt. The entire feel was different and a ton less stress in my neck and arms compared to what I was feeling before. I was actually feeling pretty good about that 194 yesterday, because I hadn’t slung up in two years and that was my highest score (by one point) after doing some load fixing. But having someone explain what you are doing wrong and why makes a world of difference.
Want to see a bullet hit a target in ultra-slow motion? Watch this video to witness some amazing things — such as a bullet jacket peeling back like a banana-skin (at time-mark 7:30). A while back, Werner Mehl of Kurzzeit.com produced a 10-minute video for the SHOT Show. This video has has been watched over 10.6 million times, making it one of the most popular shooting-related videos in history. Employing cameras recording at up to 1,000,000 (one million) frames per second, Mehl’s bullet flight video has been called “astounding” and “mesmerizing”. If you haven’t seen it yet, sit back and enjoy!
The Tactical Rifle Shooters Facebook Group recently showcased tools used to measure case headspace before and after “bumping” the shoulder. After a case is fired, hand-loaders who full-length size their cases will typically bump the shoulders back anywhere from .001″ to .0035″, depending on the rifle and application. With our 6mmBR and Dasher cases we like about .0015″ bump.
You want the amount of case sizing and bump to be the same for all your brass. To ensure uniformity, it makes sense to measure your cases before and after the FL sizing process. When we have time, we check every case. Other folks will simply check the first 3-4 cases coming out of the FL sizing die to ensure the FL die setting is correct and delivering desired headspace/bump.
Whidden Gunworks Shoulder Bump Gauge
There are a variety of tools that can be used to measure shoulder bump. Our favorite is a special cartridge-specific bushing made by Whidden Gunworks. This handy $24.00 Whidden Shoulder Bump Gauge enables you to adjust your sizing die to the desired measurement. The bump gauge is attached to your calipers with a set screw and determines the measurement from the base to the shoulder of the case. The photo below, from Tactical Rifle Shooters, shows the Whidden Bump Gauge for the .375 CheyTac cartridge.
L.E. Wilson Case Gage Depth Micrometer
If you are looking for precise “bump” measurements without having to mess with calipers and clamp-on gauge blocks, you may want to consider the L.E. Wilson Case Gage Depth Micrometer (currently $140.00). This takes very precise, repeatable measurements, but you need to know your starting point. The manufacturer explains: “Every reloader should know exactly how much your Full Length Sizing Die is pushing back the shoulder. With the NEW Case Gage Depth Micrometer you can do just that! It has never been easier to measure you cases headspace before and after sizing. The Depth Mic allows you to slip the micrometer perfectly over the top of the Gage with your case inserted into the Gage and take a measurement. Micrometer has graduations of .001″. The Case Gage Depth Micrometer is set to a zero of .100″ on the scale at our factory. Because of differences in ‘feel’ and temperature, we include a the Gage Block for you to test Zero and to adjust if necessary.”
Dave Manson Vertical Comparator with Dial Read-Out
Dave Manson states: “This tool was designed to make life easier for the advanced shooter and re-loader by allowing precise measurement of ammunition, case, and chamber headspace. With this information, the re-loader will be able to fine-tune clearances and fits between his ammunition and chamber, with resultant improvements in accuracy and case life.” The functions of the Manson Dial Cartridge Comparator are:
1. Measure headspace of factory or reloaded ammunition
2. Quantify chamber headspace by measuring headspace of a fired case
3. Ensure minimal shoulder set-back when setting up re-loading dies
4. Compare base-to-ogive length to ensure consistent bullet-to-rifling relationship.
In addition to the Dial Indicator and Stand, the $180.00 Dial Cartridge Comparator is supplied with multiple Datum Blocks of precise length and inside diameter (.3300″/.3750″/.4000″/.4375″). MORE INFO HERE.
Hornady L-N-L Headspace Comparator System
Hornady’s Lock-N-Load Headspace Comparator system is easy-to-use and handy. You can get a kit with Red bushing-holder body and 5 bushings for $45.99 at MidwayUSA. Hornady explains: “The Lock-N-Load® Headspace Comparator… gauge measures variations in brass before and after firing or re-sizing. It allows for headspace comparison between fire-formed brass and re-sized brass.” IMPORTANT: Hornady states: “To determine the proper bushing diameter for your cartridge, simply add the neck diameter and the shoulder diameter and divide that number by two. Use the bushing closest to that number.” Hornady offers seven: .188″, .240″, .330″, .350″, .375″, .400″, and .420″.
One tip — We have found the Hornady gauges may vary a little from unit to unit even with the same nominal size. If you have more than one gauge for the same cartridge, test each on your brass — you may then note a slight difference in your bump measurements. Mark one and use that consistently. There is also an Anvil Base Kit that mounts to the opposite blade on the caliper. This provides a more stable surface for the base of your case.
Pistol Brass Case DIY Bump Gauge
Last is a “field expedient” set-up if you do not have any of the comparator tools shown above. A sized .45 ACP case (or other suitable pistol case) can be used to measure shoulder bump. The mouth of the pistol case sits on the shoulder of your rifle cartridge brass.
Make sure the .45 ACP case is trimmed square and that it is round. We recommend you first run it through an expander, then size it, trim it and chamfer. Next, take the .45 ACP case and slip it over the neck of a fired, unsized rifle case with the primer removed. Align the two cases between the jaws of your calipers and note the length from rim to rim (See left photo below).
OK, now you have the length for a fired rifle case BEFORE sizing. Next, take a full-length sized rifle case (without primer) and do the same thing, placing the .45 ACP case over the neck of the FL-sized case (Right Photo). The difference between the two numbers is the amount of “bump” or set-back you are applying to the shoulder. Here the difference is .0015″. The amount of bump you need varies with your chamber and your load, but .0015-.002″ is a good initial setting.
