The 2026 Southwest Nationals (SWN) have concluded. Held at the impressive Ben Avery range in Arizona, the 2026 SWN was a very successful event with good conditions (for the most part) and impressive scores by shooters in all three divisions: Sling, F-Open, and F-TR. We congratulate the new SWN Grand Agg Champions: Bobby Gill (Sling), Ryan Mitchell (F-Open), and Brad Sauve (F-TR). This was familiar territory for Sauve who has won the SWN F-TR title before.
The SWN has both individual and team competition in all three classes. The winning team in the Sling Division was Team USAMU 2564-124X (Capt.: Jarrod McGaffic / Coach: Verne Conant). The top F-Open team was LOS CHINGONES 2590-153X (Capt.: Dennis Ray / Coach: Brian Bowling). The F-TR team competition was dominated by Team USA F-TR VORTEX 2575-123X (Capt.: Ian Klemm / Coach: Keith Trapp).
The 2026 SWN had very high participation in all classes. Observers said that 2026 may have rivaled the highest total turn-out in many years. Weather-wise, we’re told that conditions were “very manageable” for most of the week until the final day of individual competition. Wind angles and velocities became quite hard to diagnose on that last day. As a result many top shooters dropped multiple points in the last individual relay and this created major shake-ups in the leaderboard, with some very skilled shooters dropping out of the Top 20 after an otherwise impressive week.
A special congrats to our friend Gary Eliseo who actually ended up with the highest Sling Division overall score, 1240-64X. But because he used a scope throughout the match he could not win the Sling Grand Aggregate.* Gary Eliseo reported: “I had a great time at SWN 2026. It was a privilege to catch up with so many friends from around the country, managed to shoot a PB too! My UMRS/6.5 El-Mo did everything it could to make me look good.”

Report from F-Open Competitor John Masek (F-Class John)
This year’s Southwest Nationals appeared to have the highest attendance I’ve ever seen. The Mid-Range match on Wednesday isn’t usually all that full but this year every firing position was used which is something I’ve never seen before in Mid-Range. Long range was also sold out which I believe is around 365 shooters with the majority being in the F-Open category. I don’t know the exact count, but there were nearly three full pages of F-Open shooters listed — that means there could’ve been close to 200 F-Open shooters. Overall there was beautiful weather with mostly gorgeous conditions during the week, and it was great seeing everyone from across the country and even the world.
Conditions were manageable for a lot of the shooters throughout the week with some of the highest scores I’ve ever seen — 16 F-Open shooters all shot a perfect 450 points on the Palma day Friday. Saturday got just a little trickier, but still many of the top shooters were managing to only have dropped a couple points over the two days. Sunday started with mild conditions again, but the final relay on Sunday afternoon completely shook the leaderboard up. While there were certainly top shooters who were able to hold their positions… but just as many dropped quite a few places down. It was one of the trickiest conditions I’ve ever seen that didn’t involve giant winds.
* Scopes help older sling rifle shooters whose eyes are starting to wear out. But, Gary Eliseo explains: “In this event, the match director dictates that a Palma rifle be used on the first day, and if you want to shoot an ‘any rifle’ on Day Two it also must have iron sights with the third day being ‘any sights’ so ‘F-sling’ is a category where ‘any sights’ are allowed to be used on all three days but that makes us ineligible to win the Grand Aggregate.”
Our friend Dennis Santiago is a talented Service Rifle shooter, who regularly competes with an AR shooting the .223 Rem cartridge. A few seasons back, he decided to go over to the “dark side”, putting together a Palma (fullbore) rifle chambered for the .308 Winchester. Dennis selected a Competition Machine (Gary Eliseo) R1 Chassis for the project. Here’s Santiago’s account of his “true blue” Palma build.
Palma Rifle Report by Dennis Santiago
“This project was a .308 Win Palma rifle with an Eliseo R1 chassis, Rem 700 action (blue-printed with PT&G upgrades), Jewell trigger, Boots Obermeyer 1:11″-twist barrel, and Phoenix sights holding Gehmann apertures. Next comes chassis and sling set-up, initial mechanical zeroing, and load development. Yup, I have a bunch of Peterson small primer .308 brass, Sierra #2156 155gr MKs, and Varget to get started with. I’m told I can drive 155gr pills to stay supersonic to 1K. Should make for an interesting 2020. My goal was to be cozy with this blue beast by the time the Berger Southwest Nationals kicked off in February 2020.”

Pinning the Picatinny — For a Super-Solid Mount
One of the key parts of the build, Dennis explains, is mounting the top rail with pins: “Once the rail is aligned using a spin-centered optic, it locks down with three 3/16″ roll pins. That way there is no reliance on screws that can come loose. Above is a photo of the top of the Eliseo tube chassis showing the three, 3/16″ roll pins that unitize the Picatinny rail. You can also see the four brass screws that just kiss the action to fully stabilize it in the tube. The recoil ring buttresses completely around the action with metal to metal contact. There are a million details hidden inside a Gary gun.”
Phoenix Sights Front and Rear
Rise of the Phoenix — Here are the sights for the Eliseo R1. There are very few manufacturers left making these kinds of ultra-precise and repeatable iron sights.
These Ray-Vin tools help set mechanical zero on the sights. Dennis notes: “Finally a reason to pull out the Ray-Vin calibration paraphernalia to set up a mechanical zero. This photo is for all of you who still remember that those barrel flats and screws in our sight towers actually had a purpose once upon a time.”
Sling ‘N Irons — Classic Palma Configuration Dennis plans to use an Eric Hollis sling with his new blue Palma rifle.
Peterson Small Primer .308 Win Brass for Santiago’s Rig
Dennis has used Peterson Cartridge Small Rifle primer .308 Win brass. Peterson offers a “Select” version weight-sorted and length-sorted at the factory. All Select casings (in a 50ct box) are guaranteed to be within 1 grain in weight and .001″ in OAL. Peterson Select brass is available for 20 different cartridge types, including .308 Win both small primer/small flash hole and large primer/large flash hole.
Now Adapted with a Scope
Currently (in 2025) Dennis has this rifle fitted with a high-magnification Nightforce zoom scope, and he competes with his blue prone rifle in the “Any-Any” division. He usually runs the scope at about 22X power. For an older guy with aging eyes, being able to run high-magnification optics is a big plus.
With the optics Dennis has found the rifle to be exceptionally accurate. Shooting 168gr bullets it has produced 5-round groups around 1/3-MOA during testing. And it can easily hold the X-Ring at 300 yards.
Getting the Blue Rifle Ready for the Berger SW Nationals
Dennis has campaigned his rifle at recent Berger Southwest Nationals (SWN) events. At the SWN a Palma shooter can shoot iron sights, or also fit a scope and shoot in the “Any Sights” category. The week-long Berger SWN is the biggest rifle match in the Western United States. Hundreds of shooters compete in both individual and team events. The SWN begins with the Mid-Range Nationals at 600 yards. Then the Long-Range matches are held, with targets out to 1000 yards. Watch the video to see the Ben Avery facility, home of the Berger SWN:
Chassis-maker Gary Elesio at the 2017 Berger SW Nationals. Gary shoots what he sells:
We know that Competition Machine (Gary Eliseo) makes great chassis systems and Pierce Engineering (John Pierce) makes great actions. But sometimes a project comes together even better than one can imagine. The folks at Pierce Engineering crafted an Eliseo Tubegun that displayed some mind-blowing accuracy during initial testing. This was a special rifle built to a client’s spec in .22 PPC.
After his team completed the rifle, John Pierce took the Tubegun to the range to make sure everything was working right. The rifle was chambered for the .22 PPC, a known accuracy cartridge. Would this cartridge shoot in this gun? Heck yeah was the answer! The first two shots out of the gun were touching. That was promising enough. But then John drilled a five-shot group that was basically one hole! Here is that target. First two shots upper left, then the five-shot group below and to the right. Chassis-maker Gary Eliseo commented: “that’ll do just fine…”
Disclaimer: John shot some more groups with this Tubegun that were definitely NOT one-holers. That first five-shot masterpiece could not be duplicated. However, we’re told that the rifle shot other groups in the 2s, 3s, and 4s — impressive performance for a rifle designed for prone and position shooting. This shows how well the Pierce action mates to the Competition Machine chassis.
And if the owner ever wants to show off a “wallet group” for his new rifle — well he’s got that, thanks to John’s great trigger-pulling and rifle-building. Using On-Target software we measured that five-shot group at 0.189″ (see photo at right). That’s crazy small for a new gun with zero load development. That’s also a testimony to the quality of the Norma .22 PPC brass.
Why the .22 PPC Chambering?
The customer owns other Eliseo Tubeguns, but wanted something that combined extreme accuracy with very low recoil. He also wanted to be able to shoot factory brass without fire-forming. Norma makes very high-quality .22 PPC cartridge brass that is an easy load and shoot solution. In fact the folks at Pierce Engineering custom-loaded a quantity of .22 PPC ammo for this Tubegun and shipped it off to the customer along with the new rifle. NOTE: Loading ammo is not something that Pierce normally does, but this was a special client request.
Norma .22 PPC Cartridge Brass is available from Bullet Central for $75.99 for FIFTY (50) cases. That works out to $151.98 per 100. Yep that’s pricey considering that 6 years ago this same Norma brass was just $88.88 per 100 cases. But we have seen significant inflation in nearly all premium brass offerings.
Forum member Martin Tardif (aka “Killick” in our Forum) competes with a very accurate .284 Win F-Open rig fitted with a Barnard action, Brux barrel, and Eliseo F1 chassis. Unlike some F-Class shooters, Martin has tried many disciplines over the years, including service rifle and Mid-Range and Long Range sling competition. But he told us, “After experiencing arthritis in my hands and wrists, I decided I would dabble with F-Class. And that has turned into a happy obsession.” Today’s story features the object of that happy obsession — Martin’s tack-driving .284 Win he calls the “Red Rocket”.
F-Open Match Rifle — .284 Winchester “Red Rocket”
by Martin Tardif
This is the story of the new “Red Rocket”, my new F-Open rifle. It’s chambered in .284 Winchester (.317″ neck, .220″ freebore). This rifle features Barnard P action, Barnard single-stage trigger (4 oz.), and Brux 30″ one-inch straight-taper, 1:8.5″-twist barrel fitted with Blake Tuner. The barreled action rides in a Gary Eliseo Competition Machine (CMI) F1 F-Open metal chassis with Marine Corps Red powder coat. On top is March 48x52mm fixed-power High Master scope. In a previous incarnation, this same Barnard action served in a wood-stocked F-Class rig, a Red Retromod built from a modified Anschutz stock. I still have the Barnard action (and trigger), but mostly everything else is new.
Here’s the .284 Win “Red Rocket” with CMI F1 Stock, Barnard action, Brux barrel, and Blake Tuner on my SEB Mini at Burbank Rifle and Revolver Club in SoCal.
My previous F-Class rifle started out as a Palma rifle back around 2008. With a modified Anschutz prone stock, that .308 Win Palma sling gun served me well, helping me earn the 2009 California State Palma Championship. Much later I grafted more wood on and whittled that same stock into an F-Open specimen (shown below). That did get me to Long Range High Master but it definitely had limitations. For one it had annoying flex in the fore-end and the buttstock was not aligned with the barrel channel.
I wanted to upgrade my stock to get a more consistent, better-shooting F-Open performer. So in April of 2020 I contacted Gary Eliseo of Competition Machine and ordered one of his streamlined, F1 “boom-stick” chassis units. These feature a very low Center of Gravity. I sent Gary my Barnard action and had Brux send him a barrel that I had won at the 2020 SWN raffle.
This video shows Martin shooting the “Red Rocket” in California
This rifle has been a success from the very start. At its first big match, the 2020 California State Championships, the Red Rocket tied for First Place on points but finished second overall on X-count.
Martin tells us: “The new red Eliseo stock is phenomenal and far surpasses the old red stock on my RetroMod project previously featured on the Daily Bulletin. The three things I like best about this Eliseo F1 chassis system are:
1. The lean, clean, efficient engineering and styling.
2. Easy manipulation of buttstock and cheek piece adjustments, ease of bolt removal.
3. Inherent confidence in its straightness and the durability of all the parts and finish.”
“I’m extremely impressed with the potential of this rig and I have still yet to fiddle with the tuner and test some of my Wolf/KVB primers. It’s all gravy now.” — Martin Tardif
I received the finished rifle in September and was impressed with its stark and consummate functionality and there is no doubt as to that function. The collinear aspect from any angle suggests a Red Rocket Car on the Bonneville Salt Flats, so that’s what I call this rig.
Reloading Methods and Load Development
My virgin brass prep starts with a .284 neck mandrel with the occasional squirt of WD-40, then to the drill press to turn the necks to 0.014″ wall thickness with my PMA Model B turner. After a quick dip in the media tumbler I run the whole batch through my DIY cake pan annealer and they’re ready for sizing. I like the Whidden Gunworks full length bushing dies. I use a .310″ bushing and a loaded round measures .312″. After sizing, I run the cases through the tumbler for 10-15 minutes to clean them up and then they are primed. I’m using my stash of S&B primers with an RCBS benchtop primer seater with a Holland Perfect Primer Seater add-on. I do point my 180-grain Berger Hybrid bullets with a Hoover die (see below).
Here is Martin’s reloading bench. From left to right: A&D FX-120i Force Restoration Scale with Auto-Trickler V3, Hoover Bullet-Tipping Die, Whidden .284 Win FL Sizing Die with PMA click-adjust lock ring, Hodgdon H4350 powder. Martin reports: “I’m also using some of F-Class John’s Auto Trickler Methods — using two powder cups to speed up the process, hash marks on Auto Trickler gear drive, and minimal openings on FX-120i wind guards. These all improve the powder measuring.
Load Development and Accuracy Testing in Competition
I started load testing in November 2020. I tried both H4831sc and H4350 at 100 yards. I usually have excellent results with H4831sc but the Brux tube stubbornly preferred H4350. So I took a preliminary recipe (52.2 grains) to the California Long Range Championship and tied for First Place on points but got beat on Xs. Having seen a little too much vertical at the state match, I went with a lighter load that looked good for vertical at 100 yards (51.8 grains — see photo below). That load got me an overall win at our 1000-yard club match.
I wanted to fine tune that load so I started a seating depth test. I did a final head to head test, comparing .015″ jump (away from first lands contact) and .018″ jump at 1000 yards. The .015″ jump load was the clear winner. This 15-round group was shot at 1000 yards with no flags on an overcast day with no mirage.
The ShotMarker screenshot above shows 15 shots at 1000 yards with bullets seated .015″ out, switching winds and no flags, just watching the mirage. I added .25 MOA up after the first round ‘9’ (me fighting a clean barrel on first shot) and went to town.
Advice for New F-Class Shooters — by Martin Tardif
1. Watch a Top Competitor — Find a good shooter that you respect and watch and take note of their equipment, how they set up to shoot, how they shoot, what conditions they shoot in or don’t. Ideally you should ask to be squadded with them (if possible) so you can score for them. That way you’re not dividing your attention from the shooter you’re supposed to be scoring for. Be mindful not to pester them while they are setting up. Best to wait until they have finished shooting and try to ask questions off the firing line, others still shooting need to concentrate.
2. Cartridge Selection for F-Open– Go to Accurate Shooter’s 7mm Cartridge Guide and scroll to the .284 Winchester section by Charles Ballard. You can read further about the 7mm WSM and 7mm SAUM but for a caliber that’s not fussy you should stick with the .284 Win.
3. Reloading Equipment — To win, you really need ammo as perfect as you can make it. You should be able to find out everything you need to know about reloading equipment via the Accurateshooter Forum’s Reloading and Competition areas. It’s a one-stop shopping brain trust for everything F-Class, Sling, and Benchrest. And the Forum Marketplace is literally a never ending ‘Gun Show’ of For Sale items. It’s a great place to buy quality used stuff for newbies.
As a final bit of advice — BELIEVE the wind — it’s smarter than you are!
Commentary on Metal Chassis vs Wood Stock
I previously had a wood F-Class stock so flexible you could easily pinch the barrel to the fore-end with one hand and hold it there. My Eliseo metal chassis is MUCH more rigid. I don’t think there is any argument that a metal stock is more rigid than wood. I also think a metal stock with its monolithic properties has a more consistent cross-sectional density along its length than a wood stock would have due to the vagaries of grain structure. However I have no experimental data to support that theory, or how that might positively affect shot to shot consistency. I CAN say that the gun shoots better, with smaller groups and higher scores, than the previous wood stock version.
The CMI F1 chassis has three main sections: rear assembly, main assembly, and fore-end. The main assembly is a 27″-long solid billet section with milled cavities for the rear assembly and trigger group. This also supports the action V-Block which cradles the full length of the action. The V-Block is mated to the top of the billet in a milled channel but doesn’t touch the sides to avoid uneven harmonics. The rear assembly hold the LOP-adjustable butt pad/bag rider and “easy off” cheek piece. The 3-piece fore-end is fitted to the main section with screws. The complete F1 chassis with grip and cheek piece weighs 6 pounds.
F1 Chassis Maker Gary Eliseo Talks about His Design
The F1 was designed to incorporate the most important features needed in an F-Open rifle system. Top priority was placed on how the rifle tracked. The chassis had to be perfectly straight, and immune to weather so it will stay straight. On the F1, the fore-end is designed to keep the centerline of the barreled action as low as possible. This super-low center of gravity, along with the tall vertical sides, keep torque to a minimum, so the gun doesn’t twist or hop, but instead comes straight back.
The F1 chassis can be fitted with bedding blocks to accommodate any action. These action bedding blocks are carefully epoxy-bedded to the chassis so the customer’s barreled action is perfectly in line with the central axis of the chassis. In addition to optimizing tracking, I also took a look at how the shooter interfaced with the rifle. I wanted the cheek piece to be narrow so that the shooter would not be forced into applying side pressure on the stock to get their eye behind the scope. The cheek piece is also easy to remove for those who shoot without one. This also facilitates bolt removal.
If you’re interested in an F1 F-Open Chassis, contact Gary via the Competition Machine eMail page. The current price for an F1 Chassis with Cerakote finish (any color) is $1295.00. Lead time is about 12 weeks.
Green Tools for Red Rocket — Martin uses an RCBS Rock Chucker single-stage press on an Inline Fabrication UltraMount. Primers are seated with an RCBS Bench Primer fitted with Holland’s Gunsmithing Perfect Primer Seater Adapter. This provides ultra-consistent primer seating.
F-Class Match Strategies for California Ranges
My strategy for a match clearly depends on the specific location. For instance, at my home range, the Burbank Rifle and Revolver Club, which has several cuts and gullies crossing the canyon, the wind comes primarily from NNE and since the range faces slightly NNE the predominant condition will be a head or right wind so I’m looking for R to L mirage and left angled flags.
By contrast, Coalinga CA is a much more open/exposed range which can make it much more challenging. When you see all the flags going against the mirage for the majority of the string (after you’ve gone for record of course) that can be tough. So I like to watch the wind while I’m scoring and for a few minutes during sighters and shoot them in a few ‘looks’ if I can get them. But sometimes you have to go with your gut if your sighters whisper “go-for-record-you-knucklehead” and so it’s off to the races. It often seems like I should have just chased the spotter when I’m waiting out a fishtail or let-up there.
Do you have an Eliseo Tubegun that you use for sling-shooting competitions, but would like to try your hand at F-Class Open matches? Well here is a low-cost, yet very effective add-on that can transform your TubeGun into a serious F-Open rifle. The bolt-on rails also work great for load development if you want to use a front rest with 3″-wide front bag for greater stability and repeatability.
Competition Machine’s Gary Eliseo is a very smart designer as well as a talented shooter. The inventor/builder of the popular Competition Machine Tubegun chassis systems, Gary offers a bolt-on bag-rider accessory. Gary call this his PickleFork fore-end extension. The Pickleforks are rails that fit to the sides of the tubular fore-end/handguard on his chassis systems. This allows you to use a pedestal-style front rest for F-Class competition.
Pickleforks also provide a much more stable platform for load testing, varmint hunting, or any kind of rest-assisted precision shooting. These PickleForks transform a Tubegun into an ultra-stable, straight-tracking rig when used with a competition-style front rest.
Gary explains: “Now you can have the same super low-boreline, long ‘wheelbase’ and vertical sides of our innovative F1 F-Class chassis system for your tube chassis. The new PickleForks attach directly to the sides of the F-Class/Tactical fore-ends, no modifications are required. They are very rigid with no flex or twist and make the rifle track like it’s on rails.” The new Eliseo Competition Machine PickleForks are offered for a very reasonable $70.00 per pair, with Cerakote finish. (You get two metal units, one for each side of the fore-arm). For more information, visit www.GotXRing.com or call (928) 649-0742.
Product Tip from EdLongrange. We welcome reader submissions.
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.

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.
About Mike Kurtz
Michael Kurtz is owner/operator of Century Automotive & Transmission. An ASE Master L1 Technician since 1983, Mike has been an avid drag racer over the last 40 years. Mike notes: “I never owed any kind of rifle until I retired from racing. Got bit by the accuracy bug and learned about F-Class in 2021. I read several reloading and long range shooting books while I scoured the AccurateShooter Forum Marketplace for a rifle, scope, rests, and reloading equipment for my first F-Open rig. Most all of my major components I acquired via online Forums. I have to attribute the early success of my F-Open accomplishments to the vast content found on AccurateShooter.com.
I am also a member at Bayou Rifles Inc. in Houston Texas where I’ve learned from some of the best shooters in the country. The competition here is fierce but the camaraderie is second to none!”

With the variety of rimfire disciplines, from cowboy action to Olympic three-position smallbore, there are countless different rimfire designs on the market — bolt guns, lever guns, single-shots, toggle-links and more. These may shoot the same ammo, but they certainly vary in looks and ergonomics. This is testimony to human creativity.
In our Shooters’ Forum, you’ll find a long-running thread showcasing rimfire rifles for plinking, hunting, 3P Target Shooting, Silhouette, Rimfire F-Class, NRL22 and more. Here are some of the notable recently-posted rifles in that Forum thread, with brief build/component details.
ARA Benchrest Rifle with Stiller Action, Shilen Ratchet Barrel
Forum member Peebles24 showcased his cool flame-paint-job .22 LR benchrest rifle against a scenic, snowy background (never too cold to shoot right?). “I had a new rifle built this past fall by Mark Penrod at Penrod Precision. Stiller 2500X action, Shilen ratchet barrel, Jewell trigger, McMillan stock, Harrell’s tuner, Sightron SIII 10-50×60mm glass. I’m shooting it off my Arnold Machine one-piece rest made locally by Cliff Arnold. I visited the Lapua Testing Center East and got a case of Midas+.” For ammo testing results, click photo at right.
In late April the gun competed in its first ARA benchrest match in Wabash, Indiana.
Beautiful MasterClass-Stocked Rifle for Rimfire F-Class
Here is a handsome rifle belonging to Forum member Redd. Set up for prone Rimfire F-Class-style competition, this rig features a Shilen Ratchet barrel with Erik Cortina Tuner fitted to a Stiller 2500X action. It boasts a beautiful MasterClass figured Walnut stock and rides on a SEB Joy-Pod bipod up front. The optic is a Nightforce 40x45mm Competition.
CZ 457 .22 Magnum Transformed with KRG Bravo Stock
Forum member JAS-AS purchased a .22 Magnum CZ which he revived as a training rig with a new stock. He posted: “I use a CZ457 in .22 Magnum mainly as a trainer — bipod and rear bag kind of stuff. It has evolved over the last year or so. Next change will be a Lilja barrel. This because it can shoot brilliantly (at times) but not consistently. And accuracy degrades as it gets minimally dirty. Also, it doesn’t like 40gr rounds — the groups open up to 1.5 MOA. It’s at its best with 30 and 35 grain rounds running at up to 2250 fps. I believe that to be a twist-rate issue.”
The “Before” photo shows the rifle “as purchased” with a Nikon Monarch 4-16x42mm mildot scope. The “After” image shows the CZ 457 as modified. JAS-AS notes: “I added a bunch of stuff: KRG Bravo stock, Vortex Strike Eagle 5-25x56mm FFP scope, new bipod and Precision Underground bag, trigger spring. With this setup I shoot at 100 yards+ exclusively.” Show at right is a 9-shot group with the rifle at 100 yards. Three-shot groups at 100 have been below half-MOA.
Savage Mark II Squirrel/Field Rifle
This Savage Mark II rifle isn’t fancy, but it has brought much satisfaction to its owner, Forum member “Ohio Varmint Shooter”. He posted: “Just a nice field gun. Less than $200 (without scope). Cheap wooden stock, thin pencil barrel. My squirrel/field gun. There is absolutely nothing special about this… except it’s lefthanded. It shoots fine, preferring CCI standard velocity rounds. I did splurge and put a more-than-needed scope on it. Most scopes with fixed parallax (in this category), have it fixed at 50 yards. I wanted variable parallax so I could set it at 35 yards. I don’t know if it really makes any difference, but I do try to go for accurate head shots. The scope is also a little overkill in magnification, but it does help with the head shots and my aging eyes.”
“As a youth in the 70s, I always dreamed of a left-handed bolt. So getting back into shooting/hunting about 8 years ago, I was delighted to discover this gun. Growing up I had a semi-auto 22, but being a lefty … it would spit powder on my face.” — Ohio Varmint Shooter
Tikka T1x Action in Eliseo Competition Machine Chassis
Here is Gary Eliseo’s personal Rimfire Match Target Rifle with Tikka T1x action. The T1x action is carried in Competition Machine Rimfire Chassis. Gary also posted some recent 100-yard groups, using SK rifle match ammo in this rifle. Gary runs Competition Machine LLC and produces the chassis system for this cool rig, along with outstanding Across-the-Course, High Power, and F-Class chassis systems for rimfire and centerfire rifles.
Vudoo Action Benchrest Rifle with Benchmark 3-Groove Barrel
Here is a classy benchrest rig belonging to Forum member FCJIM. It features a Vudoo LBRP action, Benchmark 3-groove barrel, Harrell’s Precision tuner, NightForce Benchrest scope, and McMillan Edge stock. The stock work was done by Doan Trevor, while FCJIM did the metal work himself, using a Nevius reamer. This rig likes to shoot ELEY Black and Lapua Midas+ ammo.
Last but not least, here is a “blast from the past”. This classic lever-action single shot is crafted by CPS Rifles (Paul Shuttleworth), a boutique gun-maker specializing in single-shot rifles, particularly reproductions of the Stevens 44 1/2. Note the richly-figured wood and the lovely color case-hardening on the receiver. There is a dual Set Trigger system. You pull one trigger through a relatively long stroke until it clicks. The the second trigger breaks the shot (and drops the hammer) with just a few ounces of pull weight. This rig, fitted with MPA Vernier-type tang sights, belongs to Forum member “Mills” from Texas.

Our friend Dennis Santiago was a technical advisor for History Channel’s Top SHOT TV show. One of the notable Top Shot episodes involved the “Mad Minute”, a marksmanship drill practiced by the British Army in the decades preceding World War I. Dennis observed that the Top Shot competitors didn’t fare too well in their “Mad Minute” attempts, not scoring many hits in the alloted one-minute time period. That prompted Dennis to give it a try himself — seeing how many hits he could score in one minute with an authentic Lee-Enfield rifle. So, a while back, Dennis ran the drill at a range in California.
Dennis, an active high power rifle competitor and instructor, enjoyed his “Mad Minute” exercise, though he assures us that this takes practice to perfect. Dennis tells us: “Here is a ‘Mad Minute’ drill, done using a period correct Lee-Enfield (SMLE) No.1 Mk III rifle and Mk VII ammo. I got to the Queen’s Regulations (15 hits in one minute) on the second run and put a good group on the target at 200 yards. This is ‘jolly good fun’ to do every once in a while. This is ‘living history’ — experiencing a skill from a time when the sun never set on the British Empire.”
“Mad Minute” was a pre-World War I term used by British Army riflemen during training at the Hythe School of Musketry to describe scoring a minimum of 15 hits onto a 12″ round target at 300 yards within one minute using a bolt-action rifle (usually a Lee-Enfield or Lee-Metford rifle). It was not uncommon during the First World War for riflemen to greatly exceed this score. The record, set in 1914 by Sergeant Instructor Alfred Snoxall, was 38 hits. (From WikiPedia.)

In 2012, Gary Eliseo ran a “Mad Minute” exercise using a modern, .308 Win Eliseo RTM Tubegun of his own making. Gary ended up with 24 hits on a bull target set at 300 yards. (Gary actually had 25 hits in 25 rounds fired, but the last round hit just after the 60-second time period expired.) Note how Gary pulls the trigger with the middle finger of his right hand. This allows him to work the bolt faster, using his thumb and index finger. CLICK HERE for Eliseo Tubegun Mad Minute story.

NOTE: In an interesting coincidence, Dennis Santiago was actually in the pits pulling targets for Gary during Eliseo’s 2012 “Mad Minute” exercise.
History of the MAD MINUTE Commentary by Laurie Holland, UK Shooter
The original military requirement of the “Mad Minute” saw the soldier ready to fire with a round in the chamber, nine in the magazine, safety on. This course of fire is still followed by the GB Historic Breechloading Arms Association and other bodies in their recreated “Mad Minute” competitions.
The first 10 would go quickly, but reloads were critical, this not done by a magazine change as Gary did with the RTM or in a modern tactical or semi-auto rifle, but through slick use of ‘chargers’. It is this aspect which fouls so many of my colleagues up as it is very easy to cause a jam and a large part of 60 seconds can go in sorting it out!
Charger clips were selected for those that just held the rounds firmly enough to stop then falling out, were sand-papered and polished with a stove / fireplace polish called ‘Zebrite’ so that the rimmed rounds would slip through the clips like corn through a goose.
If you’re unfamiliar with the cock-on-closing Enfield action, it seems clumsy. With intensive practice it is very smooth and can be operated incredibly quickly. The trick is to whip the bolt back onto its stop and initiate a rebound movement that takes it and the cartridge well into the chamber thereby reducing the effort required to close the bolt and chamber the round.
The MAD MINUTE Training Standards and Target
“Mad Minute” was a pre-World War I term used by British Army riflemen during training at the Hythe School of Musketry to describe scoring a minimum of 15 hits on a target at 300 yards within one minute using a bolt-action rifle (usually a Lee-Enfield or Lee-Metford rifle). It was not uncommon during the First World War for riflemen to greatly exceed this score. The record, set in 1914 by Sergeant Instructor Alfred Snoxall, was 38 hits.
Royal Scots Fusiliers soldiers train with SMLE Mk III Lee–Enfield rifle.
Listed as “Practice number 22, Rapid Fire” of The Musketry Regulations, Part I, 1909, this drill required at least 15 shots on the Second Class target at 300 yards. The exercise was just one of several annual tests to classify a soldier as a sharpshooter, first or second class shooter depending on the points achieved.
Research indicates the Second Class target was a 48″ x 48″ square with 24″ inner circle and 36″ outer circle. The sight mark was a central 12″ x 12″ shape representing a soldier. ALL hits scored points (3 for center circle, 2 for outer circle, 1 for outer square). NOTE: Though some sources say the Mad Minute drill used a 12″-diameter round target, this appears to be a mistake from Ian Hogg’s book “The Encyclopedia of Weaponry”. No other source mentions a 12″ circle, which would be a mere 3.82 MOA. In reality the true drill target was a 48″ x 48″ square, roughly 15 times larger. (From No.WikiPedia.)
There are a variety of print books covering the history and specifications of the Lee-Enfield Rifle:
The 2023 Southwest Nationals (SWN) have concluded. Though there were very challenging wind/weather conditions this year, the 2023 SWN was a very successful mid-range and long-range event. There was some great shooting in F-Open, F-TR, and Sling divisions. We congratulate the 2023 Long-Range SWN Champions: Erik Cortina (F-Open, 1241-60X); Jeremy Newell (F-TR, 1221-49X); and Justin Skaret (Sling, 1233-50X). Notably, Skaret won Sling Division by 11 points — a big margin. SEE ALL 2023 Results.
The 600-yard champions were: Louis Buatt (F-Open, 600-39X), Luke Ramsey (F-TR, 596-31X), and Randy Teissedre (Sling, 597-33X). Buatt shoot a remarkable “clean” 600-yard match, not dropping a single point while amassing 39 “X”s. Superb performance by Louis!
Shown below is F-Open Long-Range (1000-yard) Winner Erik Cortina. Erik’s purple F-Open rifle was chambered for the new wildcat cartridge based on the 6.5 PRC necked up to 7mm. This drives high-BC 7mm Berger bullets at 2950 fps.
Our friend Gary Eliseo, maker of Competition Machine rifle chassis systems, said this was a tough match this year: “The 2023 SWN is in the books. This year we faced extremely challenging conditions with very strong erratic winds and cold temps but it was great catching up with so many friends from around the country, thank you all….”
The F-Class Worlds will be held in South Africa this year. The 2023 SWN offered good practice conditions for Team USA, which posted: “The USA F-Open team had two very successful days of practice for the upcoming World Championship in South Africa. We were also blessed to have five USA rifle team members in the top 10, with Erik Cortina taking the win and Bill Kolodziej taking silver.”

The Berger SW Nationals is one of the few American events where sling shooters compete on the same firing line as F-Class competitors (though in separate groups).
Team competitions were closely fought. In the F-TR Division, Team USA Blue (2505-70X) edged Team Texas (2504-76X) to win by one point. In F-0pen, Team Rollin Coal (2558-129X) finished three points ahead of runner-up Team Grizzly (2555-102X). In the Sling Division, U.S. Palma Gold Team (2555-104X) took first-place, ahead of U.S. NRT Gold (2504-104X).

Do you have an Eliseo Tubegun that you use for sling-shooting competitions, but would like to try your hand at F-Class Open matches? Well here is a low-cost, yet very effective add-on that can transform your TubeGun into a serious F-Open rifle. The bolt-on rails also work great for load development if you want to use a front rest with 3″-wide front bag for greater stability and repeatability.
Competition Machine’s Gary Eliseo is a very smart designer as well as a talented shooter. The inventor/builder of the popular Competition Machine Tubegun chassis systems, Gary offers a bolt-on bag-rider accessory. Gary call this his PickleFork fore-end extension. The Pickleforks are rails that fit to the sides of the tubular fore-end/handguard on his chassis systems. This allows you to use a pedestal-style front rest for F-Class competition.
Pickleforks also provide a much more stable platform for load testing, varmint hunting, or any kind of rest-assisted precision shooting. These PickleForks transform a Tubegun into an ultra-stable, straight-tracking rig when used with a competition-style front rest.
Gary explains: “Now you can have the same super low-boreline, long ‘wheelbase’ and vertical sides of our innovative F1 F-Class chassis system for your tube chassis. The new PickleForks attach directly to the sides of the F-Class/Tactical fore-ends, no modifications are required. They are very rigid with no flex or twist and make the rifle track like it’s on rails.” The new Eliseo Competition Machine PickleForks are offered for a very reasonable $70.00 per pair, with Cerakote finish. (You get two metal units, one for each side of the fore-arm). For more information, visit www.GotXRing.com or call (928) 649-0742.
Product Tip from EdLongrange. We welcome reader submissions.
The 2026 Southwest Nationals (SWN) have concluded. Held at the impressive Ben Avery range in Arizona, the 2026 SWN was a very successful event with good conditions (for the most part) and impressive scores by shooters in all three divisions: Sling, F-Open, and F-TR. We congratulate the new SWN Grand Agg Champions: Bobby Gill (Sling), Ryan Mitchell (F-Open), and Brad Sauve (F-TR). This was familiar territory for Sauve who has won the SWN F-TR title before.
Disclaimer: John shot some more groups with this Tubegun that were definitely NOT one-holers. That first five-shot masterpiece could not be duplicated. However, we’re told that the rifle shot other groups in the 2s, 3s, and 4s — impressive performance for a rifle designed for prone and position shooting. This shows how well the Pierce action mates to the Competition Machine chassis.
