When developing loads, it is important to know the true internal capacity of your cases, both fired and “as FL-sized”. In particular, when using the QuickLOAD program, it is vital to determine true case capacity. The default case capacity values listed by QuickLOAD may be off half a grain (or more) because brass from different manufacturers can vary considerably in capacity. Case capacity is a very important variable that will affect the pressure of a load and the velocity of your bullets.
To determine the true internal capacity of your cases, first weigh an empty cartridge case, then fill the case with water (all the way to the top of the neck) and weigh the case again. The difference in weight is your H20 capacity in grains. But how do you keep the H20 from flowing out the bottom? When measuring fired, unsized cases, you can simply leave the spent primer in the pocket. However, if you want to measure new brass or “as-FL sized” cases that have been deprimed, you’d have to insert a spent primer to “stem the tide”. Until now that is… 21st Century Shooting sells a great little $5.50 tool that plugs the bottom of the case so you can measure H20 capacity with ease.
When we saw 21st Century’s Primer Pocket Plug we thought “That’s smart — why didn’t someone think about that a long time ago?”. This handy “end-cap” lets you quickly measure multiple new brass cases or deprimed FL-sized cases so you can get an average H20 capacity. The primer pocket plugs are NOT case-specific (they feature an O-ring that fits the pocket). One version will work with all small-primer-pocket cases, while another works with all large-primer-pocket cartridge types. Price is $11.99 for either small-pocket or large-pocket version.
ALTERNATIVE: >If you want to measure H20 capacity on fired, sized brass, but don’t want to shell out the money for the tool (or re-insert a spent primer), here’s a simple suggestion. When you size your case, first remove the decapping rod from the die. Then you can FL-size the case without removing the primer. Of course, you will eventually have to knock the primer out, and that requires putting the decapping rod back in the die and running the case through a second time. To avoid that hassle, the Primer Pocket Plug may be worth the $5.50 over the long haul.

Todd Jarrett is one of the world’s best handgun shooters. A multi-time World Champion, Todd knows a thing or two about semi-auto pistols, particularly 1911s and 1911-based raceguns. Jarrett has been IPSC Open Division World Champion, has won the Steel Challenge World title four times (Limited Division), and has won than 100 Area championships, as well as many other action shooting events. Jarrett is the only USPSA Triple Crown Winner and he holds four USPSA National titles: Open, Limited, Production, and Limited-10. Jarrett revealed in an interview that between 1988 and 2001 he shot about 1.7 million rounds during practice: “I had a gun in my hand for two hours every day for 10 years to develop my skill level”.
In the video below, Todd explains how to get the proper grip on your handgun, and how to employ a proper stance. We’ve watched many videos on pistol shooting. This is one of the best handgun instructional videos we’ve seen. Todd explains, in easy-to-understand terms, the key elements of grip and stance. One very important point he demonstrates is how to align the grip in your hand so that the gun points naturally — something very important when rapid aiming is required. If you watch this video, you’ll learn valuable lessons — whether you shoot competitively or just want to have better control and accuracy when using your handgun defensively.
Recommended Thumbs-Forward Shooting Grip for 1911s
“Shooting semiautomatic pistols using the thumbs-forward method really becomes useful … where speed and accuracy are both needed. By positioning the thumbs-forward along the slide (or slightly off of the slide) you are in essence creating a second sighting device: wherever your shooting thumb is pointing is where the pistol is pointing. This makes it incredibly fast to draw the pistol, get your proper grip, and press forward to the target without needing to hunt around for the front sight.” — Cheaper Than Dirt Blog.
This popular video, viewed 3.9 million times on YouTube, provides a clear explanation of Minute of Angle (MOA) and how that angular measurement is used. Among novice shooters, there is much confusion over this term. In this NSSF Video, Ryan Cleckner, a former U.S. Army Sniper Instructor, defines the term “Minute of Angle” (MOA) and explains how you can adjust for windage and elevation using 1/4 or 1/8 MOA clicks on your scope. This allows you to sight-in precisely and compensate for bullet drop at various distances.
For starters, Ryan explains that, when talking about angular degrees, a “minute” is simply 1/60th. So a “Minute of Angle” is simply 1/60th of one degree of a central angle, measured either up and down (for elevation) or side to side (for windage). At 100 yards, 1 MOA equals 1.047″ on the target. This is often rounded to one inch for simplicity. Say, for example, you click up 1 MOA. That is roughly 1 inch at 100 yards, or roughly 4 inches at 400 yards, since the target area measured by 1 MOA increases in linear fashion with the distance.
More Minute of Angle (MOA) Explanatory Videos
This Gunwerks video explains that Minute of Angle subtends approximately 1″ for each 100 yards (well, 1.047″ to be more precise). That means a Minute of Angle increases in actual measured size the greater the distance of the target from the shooter.
This lengthy (24-minute) video defines Minute of Angle, and uses multiple diagrams to illustrate how MOA angular measurements works. The video also how MOA-based click values translate to point-of-impact changes at various distances.
Mike Kurtz’s Competition Machine F1 “Pro-Mod” F-Open Rifle
Today’s Sunday GunDay article showcases a modern F-Open Rifle built on a Competition Machine Aluminum Chassis. This is quite a bit different than a typical F-Open rifle with a laminated wood or wood/carbon stock. But the rifle shoots extremely well, and has already won some mid-range F-Open matches.
The rifle’s owner, a highly respected vehicle mechanic, explained his objective with this rifle: “I wanted to build a second F-Open rifle to shoot primarily 600-yard Mid-Range and also serve as my back-up long range rifle. That way I can use the same brass, bullets, and primers. So it would be chambered in 7mm-6.5 PRC, the same as my other F-Open rifle. That rig is a 7mm-6.5 PRC with Cerus XR stock, BAT Neuvo action, and Bartlein 1:9-8.7″ gain-twist barrel. I absolutely love that rifle and it has achieved several top honors. But for this project, I wanted to try some different rifle components to see how they performed in this same caliber. So I decided to go with Brux barrels, BAT Neuvo aluminum action (but see below), and an Eliseo Competition Machine F1 aluminum alloy chassis.”
BARREL SPECIFICATIONS: I ordered two Brux 7mm x 33″ barrels with 1:8.5″ twist. The contour was supposed to be 1.350″ diameter for 5″, tapered-down to 1.150″ diameter at the muzzle end. However, when the barrels arrived they were tapered down to 1.050″, a bit smaller. The folks at Brux admitted the work order was mis-read and offered to take back the barrels and make me two more. Or, I could keep the barrels with nice discount. I contacted my gunsmith, Omar Alonzo, for his advice and he said to keep them, they would shoot just fine. That turned out to be a blessing because the total rifle weight is now just three ounces under 22 pounds with one of these barrels. Omar chambered it with his 7mm-6.5PRC “no-turn” reamer that was used on my Cerus rifle. The Brux barrel was finished at 32″ with the muzzle end threaded for a V2 tuner.
ACTION and TRIGGER: I intended to use an aluminum BAT Neuvo action because I anticipated weight may be a concern, but they were on back-order with no lead time in sight. So for now I went with a used steel BAT Model M, 1.47 Octagon action that I acquired via the AccurateShooter Forum marketplace. This is a RBLP Right Eject action with magnum bolt face and 20 MOA integral Picatinny rail. The trigger is a Bix’N Andy Competition also scored on the Forum, set at 3 ounces. [NOTE: I now have an aluminum Neuvo AL in my possession. However, the F1 rifle is shooting so well, I’ll save the aluminum Neuvo for a future build.]
STOCK and FINISH: When I was planning my second F-Open 7mm-6.5 PRC rifle build, Gary Eliseo’s F1 aluminum chassis was my immediate choice. I was already familiar with Gary’s products since I started out three years ago with a used 6BR-chambered R1 tube gun. I purchased it from a Forum member and I adapted it for Mid-Range F-Open very successfully. Being a long-time drag racer and fabricator piqued my interest in these aluminum chassis combos. I contacted Gary Eliseo at Competition Machine and ordered his F1 F-Open Chassis System with one of his custom-machined bedding blocks for the Bat M action I acquired off the Forum.
Video of F1 Chassis Rifle in Action
Turn-around time was just about eight weeks, including aligning and epoxying the action bedding block into the chassis. Gary Eliseo offers full custom Cerakote services for his customers but I had something else in mind so I had the chassis sent to me “raw”, i.e. with a bare aluminum finish. At first I thought about polishing some or all the entire chassis but that would be too high maintenance. I decided to go with anodizing as I have done in the past with many race car components. Anodizing is an electrochemical process that converts the metal surface into a decorative, very durable, corrosion-resistant, anodic oxide finish that’s pretty tough and looks great!. This finish is available in many colors and in clear.
While I was surfing the internet looking for some color/combo ideas I stumbled on a local custom anodizer who had dozens of some really wild and crazy anodizing patters and color mash-ups. I messaged Stephen @ Caustic Customs and told him about my project. He replied that his specialty is paint-ball guns and this would be his first long gun but, hey, it’s aluminum! I gave him all the pieces of my F1 chassis. There were a couple of his patterns I really liked so I asked his opinion which he thought might look best for my project. He replied why not both? So I instructed him take both patterns and “run with it”. The end result is the Icy-Hot blue/red finish as seen in the pictures.
It all came together at Alonzo’s Custom Rifles in Pasadena, Texas. Omar hand-lapped the action bedding block surface to smooth-out some tiny high spots. He then skim-bedded the action with an epoxy filler to make sure the action made 100% contact with the bedding block. Barrel chambering, action fitting, trigger tuning, and final assembly was performed by Omar.
I finished the rifle with a hydraulic recoil pad from Falcon Strike and Anarchy Outdoor’s Penguin Precision Grip. Gary designed the F1 to utilize AR15-style grips. The Falcon Strike pad is not as sexy as the R.A.D. unit I have on my Cerus-stocked rifle, but I think its recoil-absorbing performance is up there with the R.A.D. unit. So, if a RAD is not in your budget or if weight is a concern, you can’t go wrong with a Falcon Strike recoil pad.
SCOPE/RINGS: My intention was to switch my March-X 8-80x56mm Majesta High Master scope between my two rifles. However the hefty stainless Bat M action nixed that idea. So to ensure the new rifle would be F-Open legal weight I went with a used March-X 10-60x56mm High Master scope that I acquired through the AccurateShooter Forum Marketplace. That 10-60X March, shown in the video, is almost 11 oz. lighter that my 8-80X March-X Majesta HM. NOTE: In some of the photos here, the rifle is fitted with an older March 8-80X scope (NOT the latest Majesta). The rings are March Superlight Titanium Ghost Rings — under 5 oz. for the set, the lightest I could find.

Gunsmith: Alonzo Custom Rifles
CARTRIDGE COMPONENTS and LOADING METHOD: I use Lapua 6.5 PRC brass, Berger 180gr Hybrid bullets and Federal 210M primers. New brass necks are expanded to 7mm and skim-turned to get a consistent .014″ neck thickness. I use a 35-degree cutter and go just a slight bit into the shoulder to ward off donuts. I then chamfer the flash holes, uniform the primer pockets, full-length size the cases, then expand and trim/chamfer the necks. My fired brass gets annealed, wet-tumble cleaned, full-length sized/expanded, and trimmed in that order. Bullets are pointed and then sorted by OAL. Primers are sorted by height and then by weight. I apply Neo-Lube to the inside of the necks with a foam Q-Tip for consistent seating psi.
This is from a 600-yard match shot with the F1 rifle a few months ago. Despite a strong wind from behind constantly switching right to left, I scored a 200-12X — good enough for Second Place.
LOAD DEVELOPMENT PROCESS: Thanks to some good 7mm-6.5 PRC load data posted on AccurateShooter.com, it helped me with a starting point to find a nice velocity node at 2865 fps using Hodgdon H4350. I did this by shooting some 2-shot groups seated .010″ off the lands. my focus was to find a node where the velocity leveled-out in at least two 0.5 grain increments in the 2850-2880 fps range. I then did a seating depth test at 100 yards to find my ideal seating depth which ended up at .024″ jumped. Next, I did some 3-shot groups at 100 yards to dial-in he barrel tuner until I got at least two consecutive ultra-tight groups. I verified that setting with a one-hole, three-shot group.

Every shooter should have a good rimfire rifle, both for fun shooting and for training. The .22 LR is very affordable to shoot, and the more potent .17 HMR and .22 WMR rounds also are great for small varmints out to 200 yards or so. Among the rimfire rifle makers, the Czech manufacturer CZ (Česká Zbrojovka) has been a world leader for many decades. In today’s Video round-up we feature a variety of CZ rimfire rifles including the the all-new CZ 457, the versatile CZ 455 VPT, and the classic CZ 452. We also include one semi-auto, the CZ 512 in .22 Winchester Magnum Rimfire (WMR).
New Generation CZ 457 with Upgrades
The CZ 457 may be the most modular precision rimfire on the market. You can swap barrels and magazines easily. The interchangeable barrel feature is by far the best feature of the CZ 457. Want to shoot .22 WMR for varmint hunts then transition to a .22 LR for precision shooting? No problem — five minutes and four screws are all you need. The CZ 457 is also an excellent value — it’s WAY better than a 10/22 but a fraction of the cost of high-end custom rimfire rigs. In the second video below, the CZ 457 goes head to head
In this video, Josh of Pursuit of Accuracy drives nails at 100 yards with his CZ 457:
And here Josh comparison-tests his Lilja-barreled CZ 457 head-to-head with the much more expensive Vudoo V22. The results may surprise you.
CZ 457 MTR Varmint — Product Showcase and Review
We really like the relatively new CZ 457 Varmint MTR .22 LR rifle. Along with other CZ 457 models, the MTR (“Match Target Rifle) Varmint features a completely new action that runs very smoothly with shorter bolt throw. The new 457s also have an American-style, push-to-fire safety. The new-generation actions have been trimmed back nearly one-inch in length, and slab-sided to reduce the footprint and weight of the actions. CZ ditched the 90º bolt rotation of the past in favor of 60º rotation. This change provides more room between bolt handle and scope for easier cycling of rounds. It also allows for the use of scopes with larger ocular bell diameters and lower ring heights.
The well-designed MTR stock has good ergonomics and nice stippling on the grip and fore-end. We were pleased to note that, with the 457 series, CZ is once again offering steel magazines that are interchangeable with older 452/455 magazines.
Here our friends at Area 419 offer a side-by-side comparison between a $2300+ rifle with Vudoo V-22 action in Manners stock and the $752.00 CZ 457. On a bang-for-the-buck basis, the CZ wins hands down. However, the Vudoo V-22 does offer centerfire-style action cycle, which helps with training. It also can run Rem 700-compatible triggers.
CZ 457 Royal Model — Handsome and Very Accurate
Above is a British review of the CZ 457 “Royal” model. This features a premium-grade Turkish walnut stock with contrasting dark fore-end tip. This rimfire rig is offered for $779.99 in the USA. CLICK HERE for a detailed written review on ShootingTimes.com. The Shooting Times’ test rifle showed very impressive accuracy with Lapua and SK Match ammo, with average 5-shot 50-yard groups under one half inch (Lapua Midas+ 0.41″; SK Long-range Match, 0.39″). SEE Full Test Results table.
CZ 455 Varmint Precision Trainer in Manners Stock
Rimfire cross-training allows PRS competitors to build their skill sets without breaking the bank (or burning out barrels). One great .22 LR option for cross-training is the CZ 455. The TFBTV video below spotlights the CZ 455 Varmint Precision Trainer (VPT), a smooth-running .22 LR bolt action. This factory rifle (now superseded by the CZ 457) was designed specifically as a training tool for precision long-range competition. It boasts a Manners composite stock and 20.5 or 24-inch heavy barrel. The 0.866″-diameter tube is threaded and suppressor-ready. The model 455 VPT is mag-fed and comes with a crisp trigger that adjusts to two pounds. If you can find one, expect to pay about $850 but you’re getting a premium Manners stock that originally cost $534 by itself.

CZ 452 — Classic Bolt-Action Rimfire Rifle
The CZ 452 is an affordable classic. It is ultra-reliable, easy to clean and maintain, and you’ll find very good examples on the used market for under $400. This is an excellent first rifle for a young family member. In this video, The TFB TV team tests a CZ 452-2E fitted with a suppressor. As the 452 series is being replaced, if you want to buy a new 2019 CZ 452, you’ll need to spend big bucks on the Grand Finale model: “Produced in limited quantity, the 452 Grand Finale (MSRP $1189.00) is a last hurrah to the venerable CZ 452. Built using the last 452 actions ever produced, on the original manual barrelling equipment and at the Brno workshop, the Grand Finale [features] hand-engraved scroll-work on the action, barrel, bottom metal and scope rings. The upgraded American walnut is trimmed with an ebony fore-end and grip cap.”
Semi-Auto CZ — Model 512 American in .22 Magnum Rimfire
The folks at Varminter.com are avid varmint hunters, who test varmint rigs in the real world, seeing how they perform in the varmint fields. Varminter.com was quite impressed with the CZ Model 512 American semi-auto .22 WMR (Winchester Magnum Rimfire) rifle. The testers found the Model 512 to be accurate, extremely reliable, and fun to shoot. Watch the video to field tests conducted in California. This self-loading rifle performed ultra-effective on California ground squirrels. Erik Mayer, Varminter.com’s publisher says: “The 22 Magnum (.22 WMR) is beginning to see a resurgence of sorts, as the rimfire ammunition becomes more readily available. Because of this, rifles like the CZ Model 512 have also begun to see a rise in interest again”. CLICK HERE for FULL REPORT with accuracy findings for multiple ammo types.

The 2025 NRA World Shooting Championship was held Sept. 30 – Oct. 4, 2025 at Camp Atterbury, Edinburgh, Indiana. Presented by Walther, this challenging event involved rifle, pistol, and shotgun shooting with a dozen disciplines — from short-range action pistol to long-range rifle.
The NRA World Shooting Championship
This championship is designed to test individuals through multiple different disciplines over a period of three days of shooting. Competitors compete in Professional and Amateur categories for cash and prizes of over $250,000. Walther and other sponsors supplied ALL firearms equipment and ammunition required for the 12 stages of competition.
To do well, competitors must be highly proficient in all shooting skills — rifle, pistol, shotgun, both rapid fire and precision, at multiple distances.
In 2025, the 12 stages were: Precision Standing Air Gun, Sporting Clays, NRA Precision Pistol, NRA Americas Rifle Challenge, FITASC, NRA ARC 2-Gun, PRS Rimfire, Biathlon, IDPA, SASS, PRS, and USPSA.
There were also six side matches with different disciplines: Steel Blast, TX .22 Bout, Back Country Steel, Sliders Away, Walther Experience, and NRA ARC Lvl 1. Lastly was the Mystery Team Shoot.
Dennis DeMille shows a young competitor at the CMP Western Games how to adjust his leather sling.
If you want to learn more about setting up your sling properly for position shooting, here are some tips from Dennis DeMille, a past Service Rifle Champion who worked for Creedmoor Sports for many years. Dennis explains how to choose a sling, and how to adjust it to fit properly.
The 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.”
Here is Brandon Green, 3-Time Nat’l High Power Champion, when he was with the USAMU. Brandon, one of the nation’s best “hard-holders”, demonstrates proper use of sling in prone position.
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, former Creedmoor G.M. Dennis DeMille 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 competing 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.
Rimfire is hot now. Across the nation, .22 LR rimfire disciplines are now the fastest growing types of rifle competition. And with today’s featured rig, the Competition Machine (Eliseo) Universal Match Rimfire Rifle (UMRR), you can shoot a variety of matches — NRA rimfire, NRL22, NRL22X, PRS Rimfire, local silhouette-style steel matches, even local rimfire benchrest matches (with a bag-rider fitted up front).
Compared to shooting centerfire, rimfire shooting is much less costly. You can get pretty good match ammo for under $8.00 per box. That works out to just 16 cents per round. Compare that to $1.60 or more per round for handloaded centerfire ammunition (counting powder, bullet, primer and brass). And you don’t have to deal with shortages of your preferred powder or primers, or spend hours hand-loading. With rimfire, just open your .22 LR ammo box, load your magazine, and shoot.
Versatile, Accurate, Affordable — Universal Match Rimfire Rifle
If you’re a Palma shooter and want to shoot rimfire with a rifle with identical ergonomics and “feel” as your centerfire tubegun, Gary Eliseo’s new Universal Match Rimfire Rifle (UMRR) is your logical choice. Or if you are looking for a high-quality bolt-action chassis rifle for NRL22 (rimfire tactical) competition, this is a great option. Running a smooth Tikka T1x action, the UMRR offers match-grade performance at an attractive price — $1950.00 for the Sport-Target model with 20″ Tikka factory barrel.*
The Tikka T1x action is a smooth, short-throw action that cycles quickly and easily:
Gary Eliseo, head honcho of Competition Machine in Arizona, explained the features of the UMRR: “Our Universal Match Rimfire Rifle system has all the features of its big brother the Universal Match Rifle System (UMRS) and will accept all the same accessories and attachments. The rimfire UMRR is identical in size to the centerfire version so it’s possible to have your centerfire and rimfire rifles set up exactly alike.” That’s ideal for guys who compete in both centerfire and smallbore matches, and likewise it is ideal for cross-training using lower-cost rimfire ammo.
The UMRR is built around the excellent Tikka T1x platform. Gary notes: “We have accurized and tuned the T1x to give the best possible performance from factory barrel and trigger. The UMRR can also be customized with a high-end match barrel and trigger. By just changing the attachments, the UMRR can be used in multiple shooting disciplines like NRL22 and NRA rimfire competitions.” Gary also noted that Tikka recently updated the T1x bolt and magazine for improved feeding and extraction. See video below.
Sport-Target UMRR Shows Excellent Accuracy with Factory Barrel
Eliseo confirms that the Sport-Target UMRR with factory Tikka barrel and trigger is easily capable of sub-MOA precision. Check out those five-shot groups shot at 50 yards. The smallest group (.210″) works out to 0.40 MOA, while the largest group (0.39″) is 0.74 MOA. Remember this is with Tikka factory barrel!
The Sport-Target UMRR with factory Tikka barrel and trigger is capable of sub-MOA precision.
The Sport-Target version uses the factory 20″ Tikka barrel with threaded muzzle that has been set back and re-chambered so the bullet will engrave the rifling, which increases the precision of the rifle significantly. The excellent Tikka trigger is tuned to a pull weight of one pound. Overall the UMRR is a great choice as an XTC/LR prone trainer or NRL competition rifle at very reasonable cost.
Superb Accuracy from UMRR Match-Target Model
The Match-Target version comes with a top of the line Benchmark match barrel and Eley match chamber with the muzzle configured for your application to accept a front sight, tuner, or threaded, there are several aftermarket single-stage or two-stage match triggers available. Current Eliseo Rifles price for the UMRR Match-Target is $2650.00.*
The Match Target with Benchmark match barrel is capable of competing at the highest level. Shown above are 50-meter sling targets and Lapua 50-meter test center results. The bottom box shows 20 shots with a superb 10.52 average score.
Updates from Tikka Improve the T1x Action and Magazine
Gary noted that Tikka has updated the Tikka bolt and magazine to improve feeding and extraction. Tikka replaced a wire-type system with a solid ejector element in the magazine. Gary says that improves the reliability of both feeding and extraction. Watch the video to see how this works.
Centerfire Accesories Will Work on UMRR
Gary notes that all the centerfire UMRS attachments will fit the UMRR, including handstop, rear balance weights, Picatinny scope rail, ARCA accessory rail, rear bag-rider, bipod mount, and front bag riding attachments. This easy adaptability makes the UMRR a true multi-discipline system for smallbore matches, NRL22/PRS rimfire competition, and cross-training.
Adapt the UMRR Easily to Multiple Shooting Disciplines
The UMRR can be easily configured for NRL, PRS, or NRA rimfire competitions by just changing the attachments. The UMRR is built on the excellent Tikka T1x barreled action that’s been accurized and bonded into the UMRR chassis system. Gary says the UMRR feeds .22 LR rounds flawlessly from the Tikka 10-round magazine, especially with the new, improved magazines. The UMRR is currently available in two basic configurations, both of which can be customized to your specifications.
Two Versions — Sport-Target and Match-Target
The Sport-Target version of the UMRR uses the factory 20″ Tikka barrel with threaded muzzle. Gary can tune the excellent Tikka T1x trigger down to a pull weight of around one pound, though for tactical work he says you may want to leave it stock. Gary tells us the Sport-Target is a great choice as an XTC/LR prone trainer or NRL22 competition rifle.
Match Target UMRR with Benchmark Custom Barrel
The Match-Target version comes with a top-of-the-line Benchmark match barrel and Eley match chamber with the muzzle configured for your application to accept a front sight, tuner, or suppressor. There are several aftermarket single-stage or two-stage match triggers available.

With spring soon changing to summer, we are in peak varmint season in many parts of the country. In an area with a high number of critters, a semi-auto varmint rifle is a good choice. You get quick follow-up shots, with reliable 20-rd and 30-rd magazines.
For this Saturday at the Movies Showcase we feature a variety of semi-auto, AR-platform rifles chambered for efficient, high-velocity varmint ammo. Cartridges include: .17 WSM, .17 Remington, .20 Practical, .204 Ruger, .22 Grendel, .223 Rem, and 6mm ARC. We conclude with a video that reviews a variety of lead-free .223 Rem ammo types.
Rock Chuck Hunting in Eastern Oregon
This video has some great backcountry footage. The host nails a number of rockchucks with his .223 Rem-chambered AR-15. The shooter says that the default AR-15 cartridge works great for varmints: “The .223 Remington becomes a rockchuck hunter’s friend with the right load: Nosler 40gr Ballistic Tip loaded over a stuffed case of H335 powder. This achieves 3800 FPS with excellent accuracy.”
.17 Remington AR-15 — Small Bullet, Ultra-High Velocity
The .17 Remington wildcat is based on the .223 Remington case necked down to .172″, with the shoulder moved back. High muzzle velocity (4000+ FPS), flat trajectory, and very low recoil are the .17 Remington’s primary attributes. It has a maximum effective range of about 440 yards on prairie dog-sized animals, but the low BCs of the small .17-cal bullets makes them quite susceptible to crosswinds at such distances.
This Varminter.com video was created in spring 2022, just in time for Rockchuck and Thermal Coyote hunts. The host noted: “This was my first experience with the .17 Remington, but I was not unaware of its history and steady popularity among varmint and predator hunters. Although finding an available and affordable .17 Remington bolt-action rifle is nearly impossible nowadays, building one in an AR-15 was simple and straight-forward.” The video has full description of all the components for the build. The .17 Rem is fast — the 25gr bullet runs 3777 FPS from an 18″ barrel (see 01:42 time-mark). READ Full Story.
.17 WSM Rimfire in Franklin Armory F17-L
What’s the ultimate rimfire varmint rifle? An AR chambered for the .17 WSM could be the answer. Eric Mayer of Varminter.com states: “The Franklin Armory F17-L in .17 Winchester Super Magnum (WSM) has a lot of firsts. It is the first semi-automatic rifle in .17 WSM now available to the general public. It is the first gas-piston system, AR-15 rimfire rifle built in partnership between Franklin Armory and Osprey Defense.”
Eric has used the .17 WSM AR shooting ground squirrels, rock squirrels, prairie dogs, and rabbits. Eric notes: “The report of the .17 WSM is nowhere near as loud as most of the centerfire [varmint] cartridges. I found that when I shot the FA-17, it did not cause the other ground squirrels… to run for cover. The lack of recoil … allowed me to see right where I hit [and] if I happened to miss, [low recoil] made for quick corrections for wind, or distance.” READ Full Report
The .17 WSM is a much larger, more powerful round than the .17 HMR. See the size difference above.
Eric Mayer created his own custom .17 WSM AR-15 varmint rifle, built with a Franklin Armory F17-V4 Upper, Aero Precision Lower, and Magpul stock. This was used in California and Arizona. READ Full Story.
.20 Practical — Fast, Accurate, Easy to Form
The .20 Practical cartridge is simply a .223 Rem necked down to .20 caliber. This is a great choice for prairie dogs — and probably our favorite wildcat for the AR-15. Just neck down your .223 Rem brass, fit a .20-Cal barrel and you’re good to go. Robert Whitley notes the the .20 Practical “is a perfect cartridge for varmint hunting and general shooting — very accurate and fast! It functions 100% out of an AR-15.”
The .20 Practical offers some notable advantages for high-volume varmint shooters. The .20 Practical delivers very high velocity with very low recoil while still providing outstanding accuracy. The .20 Practical is great option for folks who favor “fast and light” — smaller, lower-mass bullets traveling at very high velocities. This little cartridge can launch 40-grainers at over 3900 FPS, and 32-grainers even faster. This makes the .20 Practical a great choice for an AR-based varmint rifle.
.20 Practical Ultimate AR Varminter
A decade ago AccurateShooter.com created a .20 Practical AR15 Ultimate Varminter with a custom 20-caliber upper from Robert Whitley of AR-X Enterprises, LLC. That project rifle was ultra-accurate — every 5-shot group out of the gun was less than the size of a dime. That gun was auctioned off, but Robert Whitley continues to produce custom 20 Practical AR-15 uppers.
You make .20 Practical cases by simply necking down .223 Rem brass to .20 caliber. You can start with standard .223 Rem brass and even load with standard .223 Rem dies. Just swap in a smaller expander and use smaller neck bushings.
Prairie Dog Hunt with .204 Ruger AR — Watch The P-Dogs Fly
The video was created during a 2018 prairie dog safari. It has stunning footage of hits on P-Dogs at multiple distances. You can see over FIFTY hits with some amazing P-Dog aerials. Watch the first flyin’ dog at 00:20 time-mark and there’s a truly spectacular gut-busting hit at 3:13. That shows the potency of a high-speed .20-cal projectile. The shooter was using a custom-built AR-15 chambered in a .204 Ruger. That cartridge was driving 35gr Berger hollow point bullets at a stunning 4050 FPS! The rifle was fitted with a Dakota silencer suppressor and many other custom components. If you’ve never tried prairie dog hunting, watch this video start to finish and you may be hooked.
6mm ARC AR-15 Varmint Rig
This Varminter.com video examines the 6mm ARC cartridge from a varmint hunter’s perspective. Created by Hornady, the 6mm ARC was designed for target shooting and medium-sized game both in bolt guns and Modern Sporting Rifles. Hornady states: “The 6mm ARC … fits in an AR-15-pattern action, functions reliably out of standard-capacity 24- or 17-round magazines. It delivers substantially better ballistics than the .223 Rem[.]” This video examines how the 6mm ARC performs in an AR-15 for varmint and predator hunting. The host reviews available factory varmint loads. The video also examines reloading components for the 6mm ARC — brass and bullets. CLICK HERE for full article.
Cottontail Rabbit Hunting with Suppressed .204 Ruger AR-15
As a varmint hunting tool, the .204 Ruger in an AR-15 is a versatile, worthy cartridge/rifle combo for the job. This video covers a cottontail rabbit hunt. The host states that “We were contacted by a farmer who was being slammed with cottontail rabbits eating out huge portions of his alfalfa fields.” This suppressed .204 Ruger AR-15 proved seriously effective on the rabbits, driving high-velocity rounds with impressive accuracy. See more details on the Varminter.com website.
The .22 Grendel is an extremely accurate and efficient cartridge based on the 6.5 Grendel necked down to .22 caliber. The case can drive 55gr varmint bullets at high velocities — over 3500 FPS. With a faster-twist barrel you can load up to 90gr bullets at 2500 FPS. The tester achieved velocities close to a 22-250. The short, fat case fits in AR-15 magazines, but may not feed as reliably during rapid fire. The tester did experience one double-feed.
Lead-Free Ammo Offerings Tested in .223 Rem AR-15
Some states — such as California — prohibit hunting with bullets that contain lead. If you plan to hunt in an area with such restrictions, you’ll need to find a lead-free substitute. Thankfully a number of manufacturers produce ammo with solid brass projectiles or other lead-free bullet designs. This Varminter.com video reviews .223 Remington no-lead ammunition from Cor-Bon, Hornady, Nosler and Winchester. These ammo types were tested in a AR-15 varmint rifle, used in a coyote hunt featured at the end of the video. SEE Full Story on Varminter.com.
With rising crime rates in the USA, many Americans are taking a much more serious look at armed self-defense. We understand why citizens in large cities are more concerned than ever with the need to protect themselves, their families, and their homes and businesses.
Shotgun vs. Handgun — which is better for home defense? That question inspires strong opinions on both sides. We think the best answer may be “both”. There are some situations where a pistol is most handy, while there are other situations where the power (and lethality) of the shotgun clearly wins out. Some would argue that the shotgun offers an “intimidation” factor that may better resolve a threat without a shot being fired.
The NSSF, in cooperation with Thunder Ranch Training Center, has created an interesting video that examines the Shotgun vs. Handgun debate. As the Cheaper Than Dirt Blog notes: “The primary argument against the shotgun is a longer length leading to less maneuverability. On the other hand, the pistol offers better maneuverability, but lacks the stopping power of a shotgun”. Moreover, the pistol may be less accurate, according to some critics. This NSSF video looks at the question from a logical standpoint — making some surprising points.
As you can see in this still frame (above) from the video, the shooting stance of the pistol shooter (Clint) is NOT much more compact than that of the two shotgunners (compare actual muzzle positions). So a shotgun may actually be more handy inside a home than some people realize. Clint concludes that the gun selection debate “is all very easily solved by only one question: ‘If someone was going to run across a bedroom at you and they had a big knife, would you rather shoot him one time with a pistol or one time with a shotgun?’ When you answer the question you figure out why this [shotgun length] doesn’t really bother us. We simply take these [shotguns] and use them in a slightly different manner…”
In this video, Thunder Ranch Director Clint Smith explains why the overall length of a shotgun, as held in firing position against the shoulder, is not really that much greater than the “shooting stance length” of a handgun held in a proper firing position (with arms extended). Accordingly gun length/size should not be the deciding factor when choosing a firearm for home defense.
Whatever Weapon You Choose — Train with It
Fundamentally, you should use the firearm that is 100% reliable, and with which you have trained regularly. Mastery of a defensive firearm — whether shotgun or handgun — needs to be second-nature. You should be able to operate all the controls (safety, pump, decocker, slide, bolt handle etc.) by “instinct” based on hours of training. Likewise you should know how to operate the light/laser if your defensive firearm is so equipped. Importantly, you should be able to reload in darkness, and clear malfunctions without panicking.
