If you like PRS/NRL competition or just want to learn about this fast-growing practical shooting discipline, then definitely watch Shooting USA today (8/12/20). This week Shooting USA offers a special FULL-HOUR edition devoted to the inaugural Armageddon Gear AG Cup Invitational. The first-ever AG Cup showcased an all-star line-up of tactical talent. Twenty of the nation’s top PRS/NRL marksmen were invited to a two-day event at the Arena Training Facility in Georgia. $41,000 in prize money was up for grabs, with the overall match winner guaranteed twenty thousand ($20,000) in cash!
This AG CUP episode airs Wednesday 8/12/2020 on the Outdoor Channel at 9:00 PM Eastern and Pacific, 8:00 PM Central. After that it will be streamed on Vimeo for $0.99 per episode or $3.99 per month.
In this hour-long Shooting USA special, John Scoutten and Armageddon Gear’s Tom Fuller report the action and interview top precision rifle shooters. The Grand Prize of $20,000 was awarded for the best overall score, based on accuracy and time. In addition, the winner of each of the 20 stages received a $1000 cash prize. During the show, you can watch the competitors adapt to challenging stage set-ups and weather conditions. With $1000 at stake for each stage, a single miss can cost serious money!
Side Match with TN Twister Target
At the inaugural AG Cup, there was a side match with a $500 prize for the competitor who hit all five TN Twister Target plates in the shortest time. The side-match employed a modular target system from Innovative Target. This system can mount TN Twister or TN Revolver multi-plate rigs, which bolt on to the IRT Head. This provides interesting challenges quite different from a typical static PRS plate target.

Do you own or shoot an AR-platform “black rifle”? Then you know these rifles run dirty, and have some unusual maintenance requirements. On the other hand, the AR “Modern Sporting Rifle” is fun and versatile with a vast range of options among buttstocks, barrels, handguards, and grips. You can assemble a simple 16″ barrel .223 Rem rig for home defense, or build a long-barreled 6mm ARC rifle with bag-rider buttstock and high-magnification optic for long range target work. The choice is up to you.
To help with your black rifle journey, here are four helpful videos from Brownells. These will help ensure your AR rifle cycles reliably and runs longer, with reduced wear. Brownells also explains how to choose the optimal barrel twist rate. CLICK HERE to order AR parts, accessories, and ammo from Brownells.
AR Bolt/Bolt Carrier Lubrication — Smarter Methods
This video shows the proper way to lubricate an AR-15 bolt-carrier assembly. The video identifies the key metal-on-metal friction points where you actually need lubrication: the rails on the underside of the carrier, shiny wear points on top, and just a dab on the cam pin. How much oil/lubricant should you use? The AR-15 is pretty forgiving on that point. Some spots work best with grease, others work best with a lighter oil. Just keep it out of the combustion areas. Those little holes in the carrier are gas vent holes, NOT oil holes!
AR Barrel Twist Rates — What You Need to Know
AR barrels can be ordered with a variety of twist rates from 1:12″ to 1:7″. Basically, the longer/heavier the bullet you plan to shoot, the faster the twist rate you need. For example, Sierra recommends a 1:7″ twist rate for the 90gr SMK. A 1:12″ could work with the small lightweight bullets up to 55 grains. The 1:9″ barrel will stabilize the light and mid-weight bullets up to about 77 grains. We recommend a 1:8″ or 1:7″ twist rate for the best versatility. You’ll find a detailed discussion of AR twist rates on PewPewTactical.com.
Barrel Gas Block Alignment — Key to Reliable Cycling
In this Tech Tip, Brownells gun tech Steve Ostrem explains surefire methods to align your gas block. The most common problem with AR builds is poor cycling, commonly caused by misalignment between the gas block and the barrel’s gas port.
Setting Up Gas Tube Systems
This Tech Tip examines AR-platform gas systems, and shows how to select the proper length gas tube, and how to configure multiple tube systems if you change your barrel to different lengths. This is worth watching for anyone re-barreling an AR.

The 6mm GT (aka 6GT) cartridge was conceived as a “bigger Dasher” for PRS and NRL competition. The 6mm GT’s creators wanted 6mm Dasher accuracy and moderate recoil delivered via a cartridge with a slightly longer case body for better mag-feeding, longer neck for seating flexibility, and more moderate pressures. So far the 6GT has performed very well in PRS competition. Today’s story is a bit different — this is about an experiment — running a 6mm GT in an F-TR type rifle. Understand that, under current NRA rules, you may only shoot .223 Rem (5.56×45) or .308 Win (7.62×51), in official, sanctioned F-TR competition, but the 6GT is fine for F-Open. Mike McCasland wanted to see the potential of the cartridge for long-range target shooting, so he put a 6mm GT-chambered Bartlein barrel on a nice custom rifle with McMillan XIT stock and Kelbly F-Class Panda action. The results were impressive.
6mm GT — New Cartridge with Multi-Discipline Potential
Story by Mike McCasland, Texas Precision
The 6mm GT began garnering attention within PRS circles in early 2019. It promised to shoot 105-110gr 6mm bullets at 2950-3000 FPS, yet not suffer from mag-feed issues sometimes found with 6mmBR variants such as the 6 Dasher, 6BRX, and 6BRA. Moreover, since it burned less powder, the 6mm GT promised increased barrel life compared to the 6mm Creedmoor or 6XC. The 6mm GT case size should still work with the accurate powders in the Varget burn-range. I found the 6GT also worked great with H4350.
As someone who aspired to building a repeater and jumping into the PRS game, and had a spare F-TR rifle sitting around, I thought it would be fun to build up a 6mm GT to see if there was any merit to the hype. My smith, Wes Ripley of RIP Precision in Texas, builds a lot of PRS rigs, and already had the reamer on hand (a 0.120″ freebore variant).
Whidden Gunworks had some 6mm GT FL bushing die kits in stock, so I figured why not see what all the fuss was about? At the very least I could play around with the 6mm GT in F-Open Class at local club matches to see how it compared to the 6BRA, 6 Dasher, and other popular 6mm cartridges.
How the Project Got Started with Backup F-TR Rig
My 6mm GT build really started as a project spawned purely from COVID-19 Isolation boredom. This rifle primarily serves as a backup F-TR gun, and it had been relegated to performing some load development on .308 barrels, so I could spin new ones on my main match rifle. The only problem was, I had run out of .308 barrels that needed load development. So, I basically had an ideal test platform just collecting dust in the safe. All I needed was a 6mm GT-chambered barrel, since (like the 6mmBR) the 6mm GT works in a short action with a .308 Win-sized bolt-face.
6mm GT Rifle Specifications:
Action: Kelbly Panda F-Class SA RB/RP
Stock: McMillan XIT with RAD 2A
Barrel: 30″ 5R Bartlein 1:7.5″-Twist, HV Contour
Scope: Vortex Golden Eagle 15-60x52mm
Trigger: Jewell Benchrest, about 2 ounces
Bipod: Phoenix Precision
About the 6mm GT Cartridge
BRASS — The first thing you’ll find is cartridge brass choices for the 6mmGT are rather limited currently. At present, the only commercial options are Hornady and Alpha Munitions. For the die-hard Lapua fans, you can technically make 6mm GT brass from 6.5×47 Lapua, however that process is very labor-intensive.
I have used both Hornady and Alpha brass in this rifle and haven’t noticed much difference between the two. I will say that my batch of Alpha brass was slightly softer than Alpha brass I’ve used in other calibers; you could feel a difference when neck turning cases. I’m unsure if that’s a batch issue, or something specific to their 6mm GT brass as a whole. As far as performance, there was little discernable difference. Oddly enough, the Hornady brass seemed to have slightly less case capacity than the Alpha; with most other cartridges it’s the other way around.
POWDERS — The 6mm GT was designed with Hodgdon Varget in mind, and that popular powder works exceedingly well in this platform. That said, the 6mm GT can work with a wide variety of powders, some yielding better performance than Varget.
I’ve tried a multitude of powders during my initial 6mm GT load development: Varget, Shooters World Precision, RL16, VV N140, H4350, and RL-15 to name a few. In my barrel, Hodgdon H4350 seems to deliver the best velocity/accuracy combination. SD and ES also seemed to be the lowest with H4350.
Load Development for the 6mm GT — Many Powders Tested
BULLETS — The most common 0.120″ freebore chamber allows for the majority of high-BC 6mm projectiles found in both F-Class and PRS. I had good luck with the pointed 107gr Sierra Match Kings (SMK), as well as the 110gr Hornady A-Tips in my rifle. For those looking to run the heavier 112-115 grain 6mm offerings, I believe GAP designed a 0.160″ freebore reamer that gets those bullets out of the neck/shoulder junction. Shown below is the 0.120″ freebore JGS reamer print:
SUMMARY — Good Cartridge with Much Potential
Generally speaking, I think the 6mm GT is a good little round. Some may not subscribe to this theory, but I believe some cartridges are inherently easier to tune than others. I’m not sure the 6mm GT is as easy-to-tune as a 6mmBR, 6 Dasher, or 6 BRA, but I don’t think it lags that far behind.
With relatively little trouble, I was able to find loads with both Varget and H4350 that would consistently shoot very well — 0.2 to 0.3 MOA. Moreover, I found the 6GT cartridge lives up to the velocity claims made by G.A. Precision. I was easily able to push the 110gr A-Tips to 2950 FPS, and the 107gr SMKs to low 3000 FPS range without any pressure signs, or unnecessary wear and tear on the brass.
As a fun test, I ran my 6mm GT rifle in a local 1000-yard F-Class match with the 110gr A-Tips, just to see just how well they would perform. Although wind conditions of the day and some E-Target issues prevented my 6mm GT rig from getting the better of the larger 7mm and .30-Cal rifles, the 6mm GT proved itself an accurate little round at distance. Here is a 1000-yard ShotMarker target:
After putting several hundred rounds through my 6mm GT rifle, I anticipate building another 6GT on a repeater action to give PRS a try. I think if you are looking for a dual-purpose rifle that can run tactical matches (with 100% feeding reliability), and can also be used for mid-range, F-Open Class competition, the 6mm GT would be a very good option.

Review by F-Class John
Walk the line at any F-Class or Benchrest match and you’ll see plenty of SEB rests — for good reason. SEB produces some of the most popular competition shooting rests available today. With their ease of use and smart design, it is no wonder why SEB rests are so popular. But as good as they are, there are ways SEB rests can be made even better — such as making them easier to align precisely to the target during set-up. It was while shooting with his SEB NEO one day that inventor, fabricator, and competitive F-Class shooter Rod Brakhage decided to make a better mouse trap — to improve the SEB series of rests. He identified aspects of the NEO/MAX rests and SEB Mini tripod rest that could be enhanced and he then set out to improve their already great performance.
This photo shows the new Rodzilla 5-Axis top installed on a SEB Mini tripod rest. There are also Rodzilla tops for the SEB NEO and MAX two-column front rests.
Nearly a year and countless prototypes later, Rod unveiled his new Rodzilla 5-Axis Top to a select group of shooters to test and it’s been a wild ride ever since. Best of all, his top is drilled and tapped so that it can be fitted to a SEB NEO, MAX, or Mini front rest without altering the rest base in any way. To make things easy, if you don’t want to install it yourself, you can send just the bridge from your NEO/MAX or top from a Mini and Rod will install the 5-Axis unit. You pay for the Rodzilla top, and Rod will install it for free. The Rodzilla NE0/MAX tops currently sell for $549.00, while the Rodzilla Mini top is $584.00.
Watch Video to See All Features of Rodzilla 5-Axis Rest Top:
Rodzilla Top Swivels Independently of Rest Base
The first thing Rod did was allow the top to swivel independently of the base. On a NEO this makes a HUGE difference because you can now set your rest down in the general direction of your target and make final adjustments once you’re down behind the gun. This is a huge departure from the normal procedure where you find yourself moving your NEO repeatedly until it’s just right. You can do the same thing on a Mini which is actually a nice feature despite the head already swiveling because you can now lock down the Mini head and make your final adjustments behind the gun as well. This is probably the feature that stood out the most to me when I first set it up. Being able to lock the front end down and get comfortable immediately behind the gun without having to get up again was a time-saver. This also left me feeling very confident in my gun alignment to the target.
Delrin Rollers on Side Guide Stock during Recoil
The second major innovation is the addition of Delrin rollers along the side. The unit has two easily adjustable jaws that each contain a set of rollers. These rollers allow for as much or little contact as you want along the sides of your stock and provide a smooth if not near frictionless experience whether during recoil (breakaway) or when returning the gun to battery. the departure from traditional sandbags on the side quite revolutionary, and yes it is legal under NRA rules. Current NRA High Power F-Class rules have no limits on what material contacts the sides of the stock. As someone who has owned a number of front rests and filled countless small sandbags this comes as a welcome relief! The Rodzilla’s rollers give me confidence that I’ll have consistent contact with the stock without the side bags constantly shifting and needing my attention during a match.
Small, Separate Sandbags Provide Consistent Contact at Any Gun Angle
Another major Rodzilla advancement is the design of the left and right sandbags. Conventional sandbags are stationary and oriented to the rest itself meaning that if you’re shooting uphill or downhill then you may not have stock contact with the full bag surface or the stock may be at a weird angle to the sandbag. Plus, with time, conventional front sand bags can form crowns or lumps that require attention. Those problems are solved with the Rodzilla’s tilting mini-sandbags. Rod’s sandbags are very small yet still meet NRA High Power guidelines as they are filled with sand and can be visibly deformed when pushed. But otherwise, they are unlike anything you’ve seen before. Each bag is mounted on a pivoting arm allowing the gun to always keep consistent contact with each bag regardless of the angle of your rest. This provides confidence that your stock is always riding on the same amount of sandbag no matter how the rest has been placed, or the ground angle relative to target.
CONCLUSION: The Rodzilla 5-Axis Top is a Game-Changer If you have a SEB Rest you will definitely want this…
The innovative design features of the Rodzilla 5-Axis Top make SEB rests work even better. The Rodzilla Top delivers an incredibly smooth and repeatable shooting experience. Recoil seems smoother, and it is easier to align the rest on target during set-up. If you own a SEB rest and are looking to make your set-up on the line easier and faster, have near-zero breakaway force on each shot, and have consistent follow-up shots to your point of aim, then give the Rodzilla 5-Axis Top a try.

Sellier & Bellot is one of Europe’s older ammunition manufacturers, producing a wide variety of rifle and pistol ammo. The video below shows ammunition being made from start to finish, starting with raw materials. This is a fascinating video that is well worth watching. It shows some amazing machines in operation.
EDITOR: Guys, this really is an exceptional video that shows every aspect of production. I have watched dozens of videos about ammo making. This is definitely one of the BEST. Take the time to watch.
Based in Vlasim, Czech Republic, Sellier & Bellot was founded in August 5, 1825 by Louis Sellier, a German businessman of French lineage. His family were royalists who fled France during the French Revolution. Louis Sellier began manufacturing percussion caps for infantry firearms in a factory in Prague, Bohemia on the request of Francis I, the Emperor of Austria. Sellier was later joined by his countryman Jean Bellot.
Sellier & Bellot has also produced an interesting CGI video that shows what happens inside a rifle chamber and barrel when a cartridge fires can’t be seen by the naked eye (unless you are a Super-Hero with X-Ray vision). But now, with the help of 3D-style computer animation, you can see every stage in the process of a rifle round being fired.
In this X-Ray-style 3D animation illustrates the primer igniting, the propellant burning, and the bullet moving through the barrel. The video then shows how the bullet spins as it flies along its trajectory. Finally, this animation shows the bullet impacting ballistic gelatin. Watch the bullet mushroom and deform as it creates a “wound channel” in the gelatin.

If you wonder how ammo is made, starting with raw metal, check out this video from Hornady. It shows how bullet jackets are formed from copper, followed by insertion of a lead core. The jacket is then closed up over the core with the bullet taking its final shape in a die (a cannelure is applied on some bullet types). Next the video shows how cartridge brass is formed, starting with small cups of brass. The last part of the video shows how cases are primed and filled with powder, and how bullets are seated into the cases, using an automated process on a giant assembly-line.

Hornady’s New 150,000-sq-ft Ammo Production Center
In 2018, Hornady opened a new, state-of-the-art factory. The 150,000-sq-ft Hornady West Facility, featured in the video below, handles ammunition production and product distribution — Hornady produces millions of rounds annually. Hornady cartridge brass and bullets will continue to be produced at Hornady’s 100,000+ square foot factory in Grand Island, Nebraska. The Grand Island factory is open for tours Monday through Thursday. Hornady Manufacturing was founded by Joyce Hornady in 1949, so 2019 marked the company’s 70th anniversary.

There’s a good episode of Shooting USA TV this week, featuring the Rimfire Challenge World Championships. This major match attracts hundreds of competitors from around the nation. It’s fast and fun with instant feedback from ringing plates indicating hits. The Rimfire Challenge Championships is family-friendly event that’s great for all skill and experience levels. This week Shooting USA will also feature two dozen new-for-2020 products, including new pistols, rifles, shotguns, optics, holsters, and more.
Shooting USA airs Wednesday 9:00 PM Eastern and Pacific, 8:00 PM Central on Outdoor Channel. You can also watch Shooting USA any time online via Vimeo.com.
The Rimfire Challenge World Championships
The Rimfire Challenge is just about the most fun you can have with .22 LR pistols and rifles. The Rimfire Challenge Championship drew 250 competitors to the Old Fort Gun Club in Arkansas. The competition is similar to the Steel Challenge, but a lower cost, family-friendly rimfire only event. And the steel target set up is different each time, with competitors only knowing how many targets to shoot, and in what order, when they step to the shooting box.
This Rimfire Challenge Championship featured 16 stages — 8 for pistol, 8 for rifle. On each stage, shooters engage 5, 6, or 7 targets, in five separate strings of fire, with the best four runs counting for record.
NSSF Rimfire Challenge Basics
The Rimfire Challenge is a two-gun event so you need a rifle and a handgun (either a semi-auto pistol, or revolver). There are two divisions: 1) Open — Any firearm (pistol or revolver in handgun class) with scopes, optical sights, light gathering scopes, battery powered optics or lasers; and 2) Limited — Pistols and rifles with iron sights, adjustable metallic sights, and/or fiber optic. Bolt-action rifles and lever-action rifles are allowed, but self-loading (semi-auto) rifles are most popular because they can shoot quickly.
Many different stage designs can be employed at Rimfire Challenge matches. Shown above are two examples from the Rimfire Challenge Suggested Courses of Fire.
New-for-2020 Products Also Featured this Week
Shooting USA has assembled many of the new products which were to be unveiled at the NRA Annual Meetings in Nashville, Tennessee. Unfortunately that Nashville NRA event was cancelled due to the pandemic (there will be a smaller NRA Meeting in St. Louis, MO in September).

Do you shoot long, pointy Hybrid Ogive bullets? If so, you may need to modify the Hornady L-N-L Bullet Comparator tool commonly used to measure the distance from bullet base to bullet ogive.
With modern, high-BC match bullets, so much of the bullet may extend forward of the ogive that the bullet tip actually contacts the inside of the red comparator body BEFORE the bullet’s ogive contacts the gray caliber-specific insert ring attached to the red body. When this happens you will NOT get an accurate Base-to-Ogive (BTO) measure. And likewise you will not get a proper Cartridge-Base-to-Ogive (CBTO) measurement with loaded rounds.
Watch this video — it shows exactly how this measurement “fail” can happen with a .338-caliber Berger Elite hunter bullet. The tester was getting a false bullet Base-to-Ogive reading of 1.175 (0:25 timemark) before modifying his tool. The true BTO measurement, with the bullet actually contacting the gray comparator ring, is 1.121 (1:25 timemark):
How to Fix the Problem
What’s the fix? With a drill, you must relieve the back “wall” inside the red comparator holder bore. This will provide more clearance for the bullet tip. With more clearance the bullet ogive will seat properly on the gray, caliber-specific insert. The tip will no longer bottom out on the red clamping half of the tool.
The maker of this helpful video, EuLRH explains: “As we all know the CBTO (Cartridge Base to Ogive) measurement is [more useful than] COAL (Cartridge Overall Length). There are lots of products that can do this. One of them is Hornady L-N-L bullet comparator. Attention! With modern long range bullets it is possible that the bullet tip is touching the comparator body instead of the bullet ogive touching the gauge.” In this example, EuLRH worked with the 300gr Berger elite hunter bullet in .338 Caliber.
Why You Need to Check with Your Own Loads
If your bullets have this “tip touching” issue, when you measure your loaded rounds you will be seeing COAL instead of the Cartridge Base to Ogive (CBTO) length. Take a moment, test with your own bullets and your comparator to determine if you have this measurement problem. If you do, try the drilling solution shown in the video.

Many hunters and precision rifle competitors use muzzle brakes because these ported devices reduce felt recoil significantly. That make s real difference getting back on target for quick follow-up shots. While many rifle owners appreciate the benefits of muzzle brakes, they may also neglect their brakes, allowing hard carbon and powder residue to build up. Not good. You should regularly clean your muzzle brake to remove fouling and carbon build-up.
As Mark Edgreen posted: “Carbon build up on the crown and in the brake is a recipe for poor accuracy.” And another gunsmith reported that customers complained about guns that “shot out way too early” but they only needed to have the brakes cleaned.
Gunsmith and PRS/NRL competitor Jim See recently reminded his Facebook Fans about the importance of cleaning muzzle brakes: “How many times do I have to say it? You need to maintain your rifles. Clean your muzzle brakes people!”. Jim, who runs Elite Accuracy LLC, notes that hard carbon build-up in brakes can definitely harm accuracy. Look at this example:
Muzzle Brake Cleaning Methods
There are various methods for cleaning a brake, we list a variety of techniques, but we would start with NON-corrosive ultrasound. You’ll want to remove the muzzle device before doing these tasks.
1. Use Ultrasonic Cleaning Machine with cleaning solution. This may be the most efficient method: “I place my brake in the ultrasonic cleaner. Shiney as new.” (Jim Moseley).
2. Spray with commercial Carb Cleaner and brush. Then apply anti-corrosion coating.
3. Soak in half hydrogen peroxide and half vinegar. Suggestion: “Let sit over night and carbon melts off. Brush remaining carbon off, rinse and put the brake back on.” Apply anti-corrosive before mounting.
4. Soak in 50/50 solution of water and white vinegar and brush. (Be sure to apply anti-corrosion coating, such as Eezox, after soaking).
5. Tumble in liquid solution with stainless pins. Comment: “Comes out slightly faded, but perfectly clean on stainless, non-painted brakes though.” Warning — do NOT do this with threaded brakes — tumbling could affect threads of screw-on brakes. Also, tumbling can harm painted or Cerakote finishes.
Gunsmithing Tip: By fitting the muzzle brake so that the barrel crown is slightly forward, it is easier to wipe carbon fouling off the end of the barrel. See photo:

Jeff Quinn, founder of GunBlast.com, was a good-hearted, southern country boy who loved firearms. Sadly he passed away on July 27, 2020. He will be missed. His reviews were always honest and thoughtful. Notably, Jeff was a true internet pioneer. With help from his brother Boge Quinn, Jeff created Gunblast.com back in 2000. He was one of the first independent writers publishing gun reviews on the internet. And he also was one of the very first to release gun test videos on YouTube. Over the past two decades the GunBlast YouTube channel has racked up over 64 million views. Jeff Quinn led the way for popular YouTube video hosts such as 22Plinkster and Hickok 45.
This Sunday Gunday, to mark Jeff’s passing and recognize his influence in the world of firearms videos, we are reprising six of his videos from the past decade. There are a wide selection here — both rifles and pistols, rimfire and centerfire. We’ve even included a special video where Jeff tests a pre-WWI era Maxim machine gun.
The Patriot — Accurate .22-250 AI Benchrest Rifle
While Jeff Quinn focused on factory handguns, hunting rifles, and defensive shotguns, he did occasionally sample accurate custom rifles. Here he tested a unique “Patriot” .22-250 AI rig built on a sleeved Remington 700 action. This handsome rifle boasts a custom-painted, thumbhole benchrest stock with a stars-and-stripes motif. One side says “In God We Trust”, while the other side carries the message “The Right to Keep and Bear Arms”. This “Patriot” rifle delivered three-shot ragged-hole groups at 100 yards.
Tales from the Vault — Winchester 1895 Lever Gun
Along with his regular field tests, Jeff hosted videos that focused on the historical heritage of some of his favorite firearms. In the “Tales from the Vault” episode, Jeff showcases a prized example from his personal gun collection. This is an original Winchester Model 1895 lever-action rifle chambered in 30 Army, also known as 30-40 Krag.
Smith & Wesson Performance Center M629 .44 Magnum
Smith & Wesson builds some of the best wheelguns on the planet, and Performance Center models are the top of the S&W lineup. This Editor owns two S&W Performance Center revolvers, and they are both outstanding, with great triggers and accuracy that puts most semi-auto handguns to shame. In this video, Jeff Quinn tests a Performance Center six-shot Model 629 Hunter Revolver with a 8 3/8″ fluted barrel. S&W includes a Weaver-type optics rail with this capable wheelgun.
Shooting the Savage A17 in 17 HMR
The Savage model A17 delayed-blowback semi-auto in .17 HMR is one of our favorite budget varmint rifles. It is affordable, reliable, and surprisingly accurate with good .17 HMR ammo. Here Jeff Quinn tests the basic A17. We like the upgraded version with a laminated thumbhole stock, shown below. But both versions utilize the same well-designed action. This is a good choice for small varmints, such as ground squirrels, out to 200 yards.
Ruger GP100 .22 LR 10-Shot Revolver
We believe every gun enthusiast should have a good rimfire revolver, and Jeff Quinn would concur. The small size of the .22 LR cartridge allows modern wheelguns to have 10-round cylinder capacity. That’s great for target shooting, fun plinking, and gun games. Here Jeff reviews the sturdy .22 LR GP100 from Ruger. Jeff says this pistol offers “a good tight barrel/cylinder gap” and “positive ejection that kicks spent cases out really well.” He noted that this pistol was “amazingly accurate”. He tested 9 different ammo types and got 1.5″ average TEN-shot groups at 25 yards. (See video at 2:40 for targets.)
BONUS Video — Maxim Machine Gun (1914 Vintage)
The Maxim machine gun was one of the earliest successful fully-automatic weapons. Many of its revolutionary design features are still used in modern machine guns. Here Jeff Quinn tests a belt-fed, wheeled-carriage Maxim with Joe Meaux of Aklys Defense from Aklys Defense.

Have you ever expanded a .22 or 6mm cartridge all the way up to .30-caliber? If so, you know this can be a difficult procedure that stresses the case necks and neck-shoulder junction. A significant neck-size expansion done in one big jump can increase run-out, cause doughnuts, or worse yet, even split the brass. Therefore you want to proceed in increments, increasing the neck diameter in stages. One smart way to do that is to use a Progressive Press. This article explains how…
The most successful short-range brenchrest-for-score cartridge is the 30 BR. That cartridge, as well as 30 BR variants such as the 30 BRX, all start with the 6mmBR Norma parent cartridge, typically with Lapua 6mmBR brass. To get a nice 30 BR case you want to expand in stages, increasing the inside neck diameter incrementally from .243 to .308.
Darrell Jones of DJ’s Brass Service creates thousands of 30 BR cases each year. He has found a clever way to speed up the process — Darrell uses a Progressive Press. He runs his 6BR brass through four (4) separate Hornady neck-sizing dies with expander mandrels. First there is a .257 die, followed by .264 (6.5mm), .284 (7mm), and then .308. Then a fifth and final K&M die provides one last, slight expansion so the newly-fashioned 30 BR cases perfectly fit the arbor of Darrell’s neck-turning tool.
So to repeat, the case starts as .243 (6mm), then moves in up stages .257, .264, .284, and .308, with a final “finishing” step prior to neck-turning. You can see the expansion in this video, which starts with 6mmBR brass that was first hydro-formed to 6 BRX:
Watch 6mm Cases Expanded to 30-Caliber (6BRX to 30 BRX)
For this demo video, Darrell expands just one case at a time. However, he can also put multiple cases in the progressive — one per station. This takes a little more effort, Darrell says, but the results are still excellent. Darrell tells us: “I do put multiple cases in the progressive to save time. The results are the same — I just wanted to show a single-step process and how it reduces run-out by not stressing the shoulder with one big expansion from 6mm straight to 30 caliber. Doing the operation in multiple stages avoids binds and helps keep the shoulders concentric.”
This same multi-stage procedure can be use to expand other cartridge types. For example you could take .221 Fireball brass in stages up to .308 to create 300 Blackout brass.
Darrell uses caliber-specific, Hornady neck-sizing-only dies with elliptical expanders. Darrell tells us: “The Hornady elliptical expander has a reduced bearing surface that puts less strain on the brass when expanding the necks to the next size.” The fitting at the bottom of the die is the Lock-N-Load die bushing that allows fast die changes.
These particular cases used in the video were first hydro-formed to 6BRX then expanded to 30 BRX before neck turning. DJ’s Brass offers hydro-forming for many popular wildcat cartridges such as 6 PPC, 6mm Dasher, and .284 Shehane.

The sound of bullets ringing steel were heard all over the country over a three week period in July, during the 2020 Scholastic Action Shooting Program (SASP) National Virtual Championship. Over 248,000 rounds were sent down range as SASP athletes competed from their home ranges around the country. Photo and match results were posted on social media. Scores were then tallied and compared among hundreds of entrants. The ability to compete at Nationals from their home range gave teams all over the country the opportunity to finish the season as a team, competing for the national title.
Just last year, the SASP National Championship surpassed the Glock Shooting Sports Foundation (GSSF), to become the largest Action Shooting Match in history. Despite a heavily altered 2020 season, the SASP community continued to break records for participation with 1,656 event entries for the 2020 SASP National Championship.
“Virtual” Championship Held at Multiple Locations throughout the USA
Traditionally held at the Cardinal Shooting Center in Marengo, Ohio, the 2020 SASP Nationals were instead conducted in a multi-location “virtual” format. This arrangement was made “in order to protect the safety of our athletes, coaches, and familie” according to SASP National Director, Rick Leach. “The nature of our sport puts athletes and range officers in close proximity, which we could not in good conscious do with thousands of athletes in Ohio this year. We received hundreds of photos and videos from teams competing in Nationals from their home range.”
You can see SASP 2020 National Championships Results online. Just select the firearm category and class of shooters. For example, here are Centerfire Pistol Men’s results for all categories. Click image to zoom.
“This year we saw participation grow to states that are not always able to make the journey to Ohio each year for Nationals,” said SASP Director of Development, Kelvin Walton. “Although the spectacle of teams converging on the Cardinal Center to compete is part of the Nationals experience, the SASP community made the most out of an unusual season.”

Vortex’s new Diamondback® HD series of spotting scopes offer impressive performance for the price. While you can spend $2500 or more for a premium Fluorite Glass spotter, Vortex’s new HD spotting scopes cost $500-$600 MSRP. These new Diamondback spotters could be affordable options for competitive shooters and hunters. The Diamondback HD line of spotting scopes include both angled and straight body types in 16-48x65mm and 20-60x85mm configurations.
The new Diamondback HD spotters employ an HD optical system with multi-coated lenses. Vortex claims these spotters offer greater light transmission, reduced chromatic aberration, better color fidelity, and enhanced sharpness. Vortex says the “crisp resolution, brighter images, and edge-to-edge sharpness [can reduce] eye strain during long glassing sessions.” We hope to test the 20-60x85mm model to confirm these claims. HD glass should deliver greater low-light performance and clarity.
These new Diamondback HD models boast design upgrades to make them more like Vortex’s higher-end Viper HD Spotting Scopes (which start at $1049.99 MSRP). The big change is the new full-diameter focus ring as you would see on a Swarovski spotter. Vortex says: “[We] took a fresh approach to the spotter’s exterior, introducing a streamlined, snag-free profile. The helical focus wheel provides fast, fine adjustments, and an Arca-Swiss compatible foot means the Diamondback® HD mounts quickly to compatible tripod heads without additional plates. Plus, a neoprene cover comes included, keeping your spotter protected in the field.” The video below reviews the main design features of the new spotters:
Which model should you choose? The 16-48x65mm ($499.99 MSRP) is smaller and lighter, making it easier to pack or move around the firing line. The angled 16-48X spotter OAL is 14.25″ and weight is 49.8 oz., making this a good choice for competition shooters looking for an affordable spotter to watch mirage and shot markers. For hunters and other shooters seeking enhanced low-light performance and magnification, the 20-60x85mm ($599.99 MSRP) offers more light-gathering for just $100.00 more. OAL is 16.0″ and weight is 60.9 oz., about 3/4 pound heavier than its smaller brother. You make the choice.

Jeff Quinn holds his first-ever firearm, a Stevens Model 95 20ga shotgun he received at age 11.
We are sad to announce that Jeff Quinn, founder of GunBlast.com and pioneer internet gun reviewer, passed away on July 27, 2020. He will be missed. We met Jeff a few times at SHOT Show. We can tell you he was a very genuine, forthright man who truly loved the world of firearms. He was committed, to his dying days, to providing honest, reliable evaluations of guns. Over the years, GunBlast’s videos have received over 64 million views.
Jeff Quinn created GunBlast.com in the year 2000, two full decades ago. At the time, very few folks were making gun videos, and even fewer had the commitment to make it a real business. Guns.com explains how Jeff Quinn, with the help of his brother Boge Quinn, helped revolutionize gun reviewing:
“Jeff Quinn was a ‘salt of the earth’ kind of guy [who] loved God, family, and life. When he decided to pursue gun writing in 1999 as a hobby, few expected him to revolutionize the firearms industry — but that’s exactly what he did.
Tired of reading contrived gun reviews in his favorite gun mags, Quinn asked his more tech-savvy brother Boge, ‘If I could write about the gun, can you put it on the internet thing?’ Boge agreed and Quinn got to work. Jeff started photographing and writing about guns … ‘At first, we just reviewed guns that we already had’, said Boge[.] They put it online on a website they called GunBlast. At the time… the internet was still very young.
[At] their first SHOT Show as GunBlast … they visited manufacturers and asked if they could review their guns. ‘A couple of the gun companies would look at me like there was something wrong with me,’ recalled Quinn. Fortunately, a few companies saw the potential and started sending guns for review. Quinn’s personality and look resonated with the gun crowd. You knew right away that he absolutely loved guns and wanted to pass on this passion to the reader. As a result, GunBlast took off.”
In this video, Jeff Quinn’s brother Boge Quinn talks about Jeff’s life, his character, his genuine love of firearms, and the health issues with which he struggled.

This week Shooting USA TV has a great show, well worth watching. This episode features the history of U.S. military service rifles. Starting with the Trapdoor in 1873, and ending with the M14 in the 1960s, this episode traces 90 years of battle rifle development. This history lesson ends right before the general adoption of the M16 5.56x45mm infantry rifle.
In addition to history, today’s show talks about using Tripods in Precision Rifle Competition. PRS and NRL shooters can learn multiple ways to use a tripod for support during stages. These methods are explained by Staff Sergeant Tyler Payne from the USAMU Action Shooting Team.
Shooting USA airs Wednesday 9:00 PM Eastern and Pacific, 8:00 PM Central on Outdoor Channel. You can also watch Shooting USA any time online via Vimeo.com.
History of American Service Rifles
The Trapdoor was the first cartridge-firing service rifle, replacing cap and ball rifles. Then came the evolution to better, faster-cycling service rifles used in two World Wars, Korea, and the early Vietnam era. Those rifles were the Krag Jorgensen, 1903 Springfield, M1 Garand, and M14.
The Krag Jorgensen Served 1892 to 1907. First Smokeless Cartridge Rifle.
Caliber: 30-40 Krag
The 1903 Springfield Served as Primary Service Rifle 1903 to 1936.
Cartridge: .30-06 Springfield
The M1 Garand Served 1936 to 1958. First Semi-Auto Service Rifle.
Cartridge: .30-06 Springfield
The M14 Served 1959 to 1964. First Select Fire Primary Service Rifle.
Cartridge: 7.62x54mm NATO (.308 Winchester)
Tripod Tips for Precision Rifle Shooters
This week’s Shooting USA episode has a great USAMU Pro Tips Segment showing how to use a tripod for rifle support. Along with clamping the rifle on the top of the tripod, you can used the deployed legs for support in multiple ways.
SSG Tyler Payne explains: “If you’re presented with a barricade where you can support the front of the gun, the tripod really shines as a rear support. With the front of the gun and the rear of the gun both supported, it’s like shooting off of a bench.”

Kirsten Joy Weiss has created a useful video about Dry-Fire practice. Dry-Fire is a method of training without a live round in the chamber. Dry-Firing is effective, Kirsten explains, because “it eliminates all the extra noise and messages that you get when you fire a live round. Without recoil, without the sound of a shot going off etc., all you hear is the click of the trigger. This allows you to focus on your sight picture and your trigger press.” This the lastest installment in Kirsten’s ‘How to Shoot Awesomely’ series. Kisten says: “I hope it helps you, and keep on aiming true!”
The Benefits of Dry-Fire Training
If you are not doing Dry-Fire practice yet, then it’s time to start. Dry-Fire training is essential to the sling disciplines, and very useful for F-Class. 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.”
Dry-Fire Training Can Benefit Benchrest Shooters
What about benchrest? Well, we’ve found that Dry-Fire sessions can even benefit benchresters — it can help reveal flaws in your trigger technique, or inconsistencies in the way you address the rifle from shot to shot. With the gun set up with your front rest and rear bag, if you see the scope’s cross-hairs wiggle a lot when you pull the trigger, you need to work on your technique. Also, dry-fire practice can help you learn to work the bolt more smoothly so you don’t disturb the gun on the bags.

Our friend Gavin Gear of UltimateReloader.com often gets to test the latest and greatest reloading tools before they hit the market. He does a good job showing the features of new products with informative videos. Today we present three interesting products that Gavin has reviewed. First off is the impressive new RCBS Rebel reloading press. Next is the versatile three-head Case Prep Trio machine from Hornady. Third, Gavin reviews new Die Lock Rings and Breech Lock Die Bushings from Lee Precision.
RCBS Rebel Single-Stage Reloading Press
Most hand-loaders have used an RCBS Rock Chucker press at one time or another. Recently RCBS unveiled its new Rebel single-stage press. Like the Rock Chucker, the Rebel has a Cast Iron frame, but with a bigger base and taller arch (for a larger opening). The most important change is that this new Rebel press ejects primers out the bottom of the ram. This a big deal — just put a bin under the press to collect spent primers. However — take note — the Rebel has no on-press priming. You need to prime your cases separately. That’s not really a major issue, as we know the majority of our readers prime separately using hand or bench priming tools.
In this video Gavin loads ammo on the new the Rebel single-stage press and explains its notable features, including the primer ejection through the ram.
Note, RCBS is currently running a Buy Green Get Green Rebate Program. The Rebel Press qualifies for a $50.00 Rebate. And right now, MidwayUSA has the Rebel Press on sale for $186.99. So your net cost, after RCBS Rebate, is just $136.99. That’s a great deal on an excellent press.
Hornady Lock-N-Load Case Prep Trio
Hornady’s compact Case Prep Trio machine (item 050160) packs a lot of functionality in a small package. This triple-threat tool has a small footprint, yet it can perform three tasks as well as much more expensive, tower-style case prep units.
Gavin Gear does a nice job explaining the features of the Case Prep trio. Watch this video to see how it can help you perform chamfering, deburring, and pimer pocket uniforming tasks more efficiently.
With three active stations, you can chamfer, deburr and clean primer pockets without having to change tools. The Case Prep Trio ships with inside chamfer, outside chamfer, and deburr tools. You can also use the machine with other optional 8/32 threaded accessories such as primer pocket reamers and case neck brushes. We’ve used this machine and it works well. The only negative is that you will get metal shavings on your bench (unlike some of the larger case prep centers). We’ve seen some guys put a small pan under the power head — then you can just dump the shavings out of the pan.
New Lee Die Lock Rings and Spline Drive Breech Lock Bushings
New basic lock ring in left hand. Older non-splined ring in right hand.
In this recent video Gavin Gear reviews three types of die accessories from LEE. These work for virtually all standard dies, not just LEE-brand reloading dies. The new LEE basic silver-finish die lock rings now feature splines for enhanced grip and compatibility with LEE’s new die lock ring wrench (photo right). They still boast a rubber 0-Ring that helps “float” the die for improved cartridge concentricity.
LEE’s new Ultimate Die Lock Rings have two major improvements — a colorful anodized finish, and a split-ring design with a tensioning screw, that allows these rings to be clamped securely to your dies. Available as a set, this package includes three ultimate die lock rings, and a plastic die lock ring wrench.
Gavin also reviews Lee’s new Spline Drive Breech Lock Bushings for use with presses fitted with LEE’s Breech Lock system. These new Breech Lock bushings allow rapid change-out of dies without modifying the setting. The colorful new bushings feature splines on top that work with the new Lee Lock ring wrench shown above. In addition, the Breech Lock Bushings have a clamp to preserve die depth setting.

Recommended M1 Garand Manual
Along with The Essential M1 Garand book by Jim Thompson, there are many other good M1 Garand print resources. 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 CMP also offers many other M1 Garand print resources including:
What happens when a round goes off unsafely in an AR? Watch this video and see. At about the 00:40 time-mark the shooter has a malfunction (click no bang), with a round. He then removes the magazine, and clears the chamber (we think). On the next round, at 00:53 you hear a “Bang” and see a big puff of smoke coming out of the upper receiver (see photo at right). This has been called a “detonation” by the video-maker, but we’re not 100% sure what happened. What do you guys think? Watch the video carefully, and state your conclusions in the comment section if you wish.
What Caused this Malfunction? Watch Video…
In any event, the shooter is fortunate his upper did not completely fracture, launching shrapnel into his face or other body parts. This could have turned out much worse. Here are screen-shots from the video, showing details of the gun after the accident, along with the recovered brass case, which separated near the case-head.
