Tubb T7T 2-Stage Trigger for Rem 700 and Rem-Clone Actions

David Tubb two-stage 2-stage T7T trigger Rem 700 Remington clone high power

If you’re planning a build with a Remington or Rem-clone action, take heed. Here’s a trigger upgrade worth considering for an F-Class or Long-Range rig. David Tubb offers an excellent two-stage trigger for Remington 700 rifles, the Model T7T. Priced at $349.00, the Tubb T7T Trigger is a true two-stage design: first and second stages are independently adjustable for both weight and feel. Overall (combined stage) trigger pull weight can be adjusted from just under 1 pound to slightly over 3.5 pounds.

If you are interested in the T7T, watch these two videos. The first shows how to adjust pull-weights for both stages. The second video shows how to modify your stock to provide clearance for the T7T.

This video shows how to adjust the new Tubb T7T two-stage trigger for Remington 700s:

The new T7T is a quality product. We’ve received good feedback from “early adopters” who tell us the two-stage function works well. While installation of the T7T may require minor modifications to your action, most gun owners with basic mechanical skills can install the T7T by themselves. The T7T is made using stainless steel and aluminum for maximum corrosion resistance. Note, a full installation of the T7T trigger (either Right-Hand or Left-Hand) also requires a companion T7T bolt release, offered by DavidTubb.com for $10.00.

Norm Harrold and His Championship-Winning F-Open Rig

F-Class Open F-Open Norm Norman Harrold Champion Championship 2018 Raton NM New Mexico 284 Shehane Berger Bullets

After Norm Harrold won the 2018 F-Open National Championship in Raton, New Mexico, setting a new 1000-yard National Record in the process, many of our Forum members wanted to see Norm’s championship-winning rifle, and learn more about Norm’s experience at the Nationals. Read on for coverage of Norm’s equipment and .284 Shehane ammo. Scroll down and you’ll find a detailed video showing how McMillan builds the advanced Kestros ZR stocks, like the one Norm used at Raton.

Norm posted: “I made it home from Raton 2018 F-Class Nationals and what an unbelievably amazing week I had. I was blessed enough to bring home a new F-Open 1000-yard record and the National Championship! Our Team McMillan took second in Mid-range and fourth overall in Long Range. I am so thankful and blessed to have this opportunity and to be able to do it with such a stand-up group of competitors and lifelong friends. Thanks to all our sponsors: McMillan Fiberglass Stocks, Nightforce Optics, Kelbly’s [Actions], Bartlein Barrels, and Berger Bullets.”

Gun and Load: Norm’s F-Open rig features a McMillan Kestros ZR stock and Bartlein barrel chambered for the .284 Shehane, which has a bit more case capacity than a standard .284 Winchester. Norm loaded Berger 184gr 7mm bullets in Lapua brass. Norm revealed his load in an Erik Cortina YouTube Video. Fellow shooter Erik Cortina joked — “the minute this video goes live, the 184s will be hard to find”. Norm says “Stock up guys — they shoot good!”

Here Norm Harrold shows his shooting form. Note how low the McMillan Kestros ZR forearm sits on Norm’s SEB NEO front rest. Norm also uses a large footprint rear bag for enhanced stability.

Harrold Shoots 200-22X to Smash 1000-Yard F-Open Record
On a rainy day at Raton, Norm shot brilliantly to set a new F-Open National Record: 200-22X at 1000 yards. (The previous record was 200-17X.) How could he get 22 Xs for a 20-shot string? Under NRA rules, if you shoot all Xs for the full string, you are allowed to keep shooting for as long as you can put shots in the X-Ring. Norm almost missed the chance to extend his X-Count. After his 20th shot, Norm recalled, “I said ‘I’m done, give me my target’, but … my shooting partner said ‘No! Keep shooting!’” So Norm did, drilling two more Xs to set the new National Record.

Kelly McMillan Shows Design and Construction of the Kestros ZR:

In this video, Kelly McMillan explains the design features and construction methods for the Kestros ZR, a fiberglass Kestros with aluminum extension rails in the front. Kelly explains “how and why we made the stock the way we did” and he shows how to retro-fit standard Kestros stocks with the new front rails. On the ZR the rails are anchored to a reinforced area for extra rigidity. In addition, the cantilevered rails are milled to be perfectly parallel. If you shoot F-Class we strongly recommend you watch this video.

Best of Both Worlds: Hybrid Wood and Aluminum F-Class Stock

Accurateshooter.com Seb Lambang F-Class wood aluminum stock bag rider

NOTE: This is an older article, but with the F-Class National Championships underway this week in Raton, NM, we thought our readers might enjoy this view of a very rare and unique F-Class rig. This hybrid wood and aluminum stock is a “one-of-kind” custom, crafted by Sebastian (“Seb”) Lambang, creator of the SEB Coaxial Rests and Coaxial Joystick Bipod.

Back in 2013, our friend Seb Lambang engineered an impressive wood and aluminum F-Class stock. The stock features a long, box-section aluminum fore-end with a wood rear section and wood-trimmed “wings” on the front bag-rider. The aluminum fore-arm has “buick vents” for weight reduction. From the end of the action rearward, the stock is mostly wood, with light and dark fancy wood laminates on opposite sides (left and right).

Accurateshooter.com Seb Lambang F-Class wood aluminum stock bag rider

The foot of the buttstock has a very wide aluminum rear bag-rider with rails. The rear wood section appears to be two solid pieces of wood — but that is deceiving. Seb explains: “To save weight, the buttstock is hollow (using thin-walled wood)”. To strengthen the construction, Seb added carbon fiber inside the buttstock. So what you see is a wood outer shell with carbon fiber layers on the inside. The stock sports vertically-adjustable cheek-piece and buttplate. The thick, rubber buttpad should diminish felt recoil even when shooting big cartridges with heavy bullets.

This is an interesting, innovative stock design. And as with everything Seb produces, the craftsmanship, fit and finish are superb.

To go with this gun, Seb also crafted a handsome set of angled scope rails with beautifully-machined scope rings. Imagine being able to custom-make one-off products of this quality in your own machine shop!

Smallbore F-Class National Championship — New Discipline

Camp Wa-Ke-De indiana 2018 smallbore F-Class Jim Murphy

Here’s a new discipline we think should become very popular — Smallbore F-Class with .22 LR rimfire rifles. Rest-supported prone rimfire matches have been held around the world for quite some time, but only a few years ago was the discipline officially codified in the NRA Smallbore Rulebook. And the first-ever Smallbore F-Class National Championship was held this past July in conjunction with the Smallbore Nationals at Camp Wa-Ke’-De in Bristol, Indiana. The Nationals involved multiple days of prone shooting at 50 meters and 100 yards.*

Jim Murphy, a respected centerfire shooter and coach, became America’s very first Smallbore F-Class National Champion, shooting an impressive 2374-146X score. Fourteen points behind, but with the same X-Count, was runner-up David Pessall (2360-146X). Jess Huehn finished third with 2358-137X.

Competitors could either shoot off a bipod F-TR style, or use a front rest. In this photo from the inaugural NRA National Championship you can see a shooter with SEB Coaxial Rest at top, with a competitor using a low-profile bipod at bottom. Note the extended handle used to adjust bipod elevation. This is not a coaxial joystick, but rather a long handle attached to the mariner wheel.

For more match results read Hap Rocketto’s Shooting Sports USA Match Report.

Smallbore F-Class — The Future Looks Bright
With the high cost of centerfire ammunition, and the limited number of 1000-yard (or even 600-yard) ranges, we can envision that Rimfire F-Class will become a popular event at ranges across the country. Clubs don’t even need benches — just a 100-yard target bay and flat ground for the shooters. You can start with an inexpensive rimfire rig and Harris bipod. Then work up from there. Here is a custom rimfire F-TR style rig that belongs to F-Class ace and past centerfire F-TR National Champion James Crofts.

Camp Wa-Ke-De indiana 2018 smallbore F-Class Jim Murphy

Smallbore F-Class Course of Fire
The Smallbore F-Class Nationals was completed on paper targets at 50 yards and 100 yards. According to Shooting Sports USA: “The tournament ran during the any sight and metric phases of the 2018 NRA National Smallbore Rifle Championships, featuring a daily course of fire which mirrored the sling shooters, 40 shots at 50 meters on the A-50 target, a Metric Dewar, followed by 40 shots at 100 yards on the A-33 target. Although the international targets were shot throughout, the first two days were titled ‘conventional’ and the last two ‘metric’.”

The specifics of the match such as rifle requirements, rests, and sights may be found in the Provisional Smallbore Rifle F-Class Rules (Section 23), found on page 65 of the current NRA Smallbore Rifle rulebook. Any rules not covered in Section 23 will [reference] the normal rules of Sections 1 through 22.

* All ‘short range’ F-Class was shot at 50 meters on the A-50, the 50 meter International Shooting Sports Federation (ISSF) target. All ‘long range’ stages were shot at 100 yards using the NRA A-33 target, the ISSF 300-meter target reduced to 100 yards.

F-TR Tech — the Low-Profile Solution Pioneered by Pierce

F-TR Scoville Stock F-Class Rifle

One recent trend in F-TR competition is the use of low-profile, benchrest-type stocks shot with a light hand-hold and little or no face contact. For this method of F-TR shooting to work, you need the right equipment, and practice a “minimalist” shooting technique. One of the pioneers in this style of F-TR shooting is action-maker John Pierce of Pierce Engineering. Above you can see John shooting one of his F-TR rifles at the 2015 Canadian F-Class Championships. Note the straight-line stock and see how the adjustable bipod is set quite low to the ground (in fact the bipod’s arms are almost straight out).

F-TR Scoville Stock F-Class Rifle

Members of the Michigan F-TR Team, including Bryan Litz, have used similar rigs with success. Bryan said it took a while to adapt his shooting technique to this kind of rig, but there is a pay-off. Armed with a Pierce-built F-TR rifle, Bryan won his first-ever F-TR Match. Bryan explains the technique he uses when shooting this kind of rifle:

“Coming over from sling shooting, I knew there would be unique challenges to F-TR which I wanted to learn prior to (not during) a major tournament. I learned a new shooting position which doesn’t involve drawing the right knee up. For F-TR I get more straight behind the gun rather than at an angle. I found that the rifle shoots best with very light cheek, shoulder and grip pressure, approaching free recoil. This is how Eric Stecker shot his similar rifle into second place in the SW Nationals [with high X-Count by a large margin]. I learned the rifle’s sensitivity to different bipod and rear bag supports, and found the best buttplate position to allow the rifle to track and stay on target after recoil. This set-up shot best with a mostly free-recoil approach, that means ‘hovering’ over the comb, rather than resting your head on the stock. This took some ‘getting used to’ in terms of neck and back muscle tone. These are the kind of details I think it’s important to focus on when entering a new discipline.”

Bryan’s Pierce-built F-TR rig is a tack-driver: “I can certainly vouch for this set-up! In [a 2015] mid-range State Championship in Midland, MI, I shot my Pierce rifle into first place with a 598-44X (20 shots at 300, 500 and 600). Once you get used to the positioning and way of shooting these rifles, they just pour shots through the center of the target.”

Pierce F-TR Rifles with Scoville Stocks
Shown below are three complete Pierce F-TR rifles, along with a barreled action for comparison. The carbon-fiber/composite stocks are built by Bob Scoville. These Scoville stocks are very light, yet very strong and very stiff.

Transform Your TubeGun with PickleFork Front Rails

Eliseo Tubegun Chassis Pickle-Fork Picklefork forend fore-end F-TR F-Class Bag Rider

Are you a sling shooter who would like to get into the F-Class game? Gary Eliseo has a great, affordable solution for TubeGun owners. A simply bolt-on forearm accessory lets your TubeGun ride a conventional front bag like a dream, with less torque effect and great tracking.

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 has come up with something new, which he calls the PickleForks. These 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. It also provides a much more stable platform for load testing, varmint hunting, or any kind of rest-assisted precision shooting. These new PickleForks transform a Tubegun into an ultra-stable, straight-tracking rig when used with a competition-style front rest.

Eliseo Tubegun Chassis Pickle-Fork Picklefork forend fore-end F-TR F-Class Bag Rider

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.

F-Class Beauty from KW Precision LLC

Delaware F-Open F-Class rifle Cerus Brux barrel Panda Action

Forum member Keith W. (aka “Cigarcop”) of KW Precision LLC is a talented riflesmith whose projects display outstanding finish work and attention to detail. Keith does some of the best bedding work we’ve ever seen. Here is one of his latest creations. Keith recently completed a stunning F-Class rig for a shooter in Delaware. It’s a beauty, that’s for sure. Keith has posted more details about this rifle in a Shooters’ Forum Thread.

Delaware F-Open F-Class rifle Cerus Brux barrel Panda Action

This handsome rifle features a polished Stolle (Kelbly) Panda Action, and two (2) Brux barrels, both chambered for the .284 Winchester cartridge. The real eye-catching component of this rifle is the stunning Cerus F-Open stock. This features multiple laminations with highly-figured Walnut on the sides. This certainly ain’t your “off-the-shelf” laminated stock. This just shows the beauty that can be achieved with carefully-chosen lamination layers (plus 12 coats of clear).

This beautiful F-Open rig features a laminated wood stock with stunning figured walnut on the outside.

Keith of KW Precision LLC is renowned for his bedding work, and this rifle shows why. Keith takes great pride in his work, and his attention to detail is second to none. This bedding job is as good as it gets.

Bringing out the figure in the wood requires multiple finish coats (and careful sanding between coats). But the results are worth it. Shown below is the Cerus stock, BEFORE the finish coats were applied. It took time and effort to transform the “naked” Cerus stock into a true stunner. Keith applied twelve (12) coats of PPG Automotive Clear with wet sanding between each coat.

Home-Built F-Open Rifle and Dual-Belt-Drive Front Rest

Tikka 590 Essex Custom

We like Do-It-Yourself (DIY) projects. It takes initiative, creativity, and dedication to make your own hardware, and that’s worth acknowledging. For you dedicated DIY guys, here’s a great project that should inspire. Here is an owner designed and crafted F-Open rig, complete with home-built, belt-drive front rest.

Some of our mechanically-skilled readers chamber their own barrels or bed their own stocks. But these are relatively simple tasks compared to the jobs of constructing an entire rifle plus building an advanced front rest from scratch. Well that’s exactly what Forum member Steve B. (aka Essexboy) did a couple seasons back. He built his own rifle and an impressive twin-belt-drive pedestal rest. (Click photo below for large version). And get this, Steve’s home-made rifle was victorious in its first-ever match. Steve reports: “I shot my first Comp with the rifle … and managed to win with a score of 239-21!” (The match was shot at 300/500/600/1000/1100 with English scoring of 5 points for center bullseye).

Do-It-Yourself F-Open Rig from England
Steve, who hails from Essex in the UK, constructed virtually every component of his skeleton-style rifle except the 28″ HV Bartlein barrel (chambered as a 6mm Dasher) and the Tikka 590 donor action. Steve also did all the design and fabrication work on his one-of-a-kind front rest. Steve tells us: “Over the last year or so, I made this rifle stock and rest. I managed to make it all on a little Myford Lathe, as you can tell I’m no machinist but it saved me a load of money — so far I’ve got about $200 invested plus the barrelled action. The stock is aluminum except for the stainless steel bag runner. The rifle came in at one ounce under weight limit for F-Class Open division.” Steve did get help with the chambering and barrel-fitting, but he hopes to do all the barrel work himself on his next project.

Tikka 590 Essex CustomThe gun is very accurate. Steve notes: “I have shot the rifle to 1100 yards and it shoots well. Last time out the rifle dropped just one point at 1000 yards and 5 points at 1100 yards [English scoring system]. I know it’s not pretty, but it got me shooting long range F-Class for peanuts.” Message to Steve: Don’t worry how it looks. As another Forum member observed: “Any rifle that shoots well at 1100 yards is beautiful….”

Steve started with a Tikka 590 action: “The whole stock was made on a small (6.5×13) lathe and a vertical slide. This caused a few head scratching moments, figuring out how to hold the T6/HE30 alloy for the milling/turning operations, but it did teach me a few things. The hardest parts were clamping the longer sections (such as the fore-end) and keeping it all square. Due to the short cross-slide travel I had to keep re-setting the parts. I managed to keep all measurements to 0.001″ (one thousandth). I’m most proud of the trigger guard (photo below). This took a full day but came out really well, even if I say so myself.”

Tikka 590 Essex Custom

Belt-Driven Front Rest
We’re impressed with Steve’s ingenious front rest. Steve explains: “The rest is belt-driven and still in the experimental stage — hence no powder coating or polishing yet. I may have gone over the top as the key moving parts (the pulleys) run on three (3) types of bearings: radial; reamed bush; and a ball race. The main post runs on a radial bearing and the feet even have bearings in them, so when I raise the main body up (for rough height adjustment) the foot stays static.”

Tikka 590 Essex Custom

Will Steve build another rifle? Steve says he will, and he’s upgraded his tools: “Since building the rifle I have acquired a bigger lathe (Harrison m250) and a milling machine. For the next project I hope to be able to do the barrel work (threading, chambering, crowning) as well.” The next gun might be another Dasher. Steve explains: “After extensive reading on AccurateShooter.com, I chose the 6mm Dasher chambering, as I have a shoulder problem and can’t shoot a rifle with a lot of recoil.”

Yanks Enjoy Irish Hospitality at Emerald Match

Emerald Match Ireland 2018 Tullamore Midland range Phil Kelley James Crofts

American shooters have been enjoying Irish hospitality this week in Ireland, while attending attending the Emerald 2018 match at Midlands National Shooting Centre of Ireland (Tullamore). Our friends James Crofts, Phil Kelley, and Aussie Jenni Hausler provided these images from the event — both at the range and off. The Yanks are off to a good start. James reports: “Day one scores are out and Team USA is on top. Madison Bramley topped F-Open and I held on for F-TR. I also won the 1000-yard match. My equipment performed flawlessly — rifle built by Keith Weil of KW Precision, Cerus Stock by Will McCloskey, and BRM action by Jim Borden.”

American Phil Kelley posted: “As always our hosts are outstanding. Man, love this range! Ready for the big match starting tomorrow.”

Phil Kelley enjoyed the Team Match and long-range Clays Fun Match which preceded the main event. Phil posted: “A great day, with a busy line at 1100 and 1200 yards in Ireland. Last fun day included some great competition. Team USA did well. After getting completely destroyed at 1100 yards, I was able to win the 1200 yard match; with a miss! First ever board miss, it’s only 6’ wide. 12-14 mph winds with a lying, heavy mirage.”

The day finished with a fun (and challenging) Clay Pigeon Shoot at roughly 1235 yards. Phil noted: “Ellis Berry, James Crofts and myself were one of only a handful to hit the 4.25″ clay target within 5 shots in these conditions.” Think you can do that? That 4.25″ clay bird represents a mere 0.338 MOA at 1200 Yards! Not easy folks…

Posting on Facebook, Mias Nieuwoudt had an interesting observation about the challenge of 1200 yards: “On average it seems the old 308s ran out of steam compared to our F-Open rigs at 1200 yards. Maybe a 40° scope rail with the targets angled backwards at 30° so you can lob the points like mortars!”

Father Develops .223 Rem F-TR Load for His Daughter

F-TR load development .223 Rem Remington Sierra TMK

Jeremy Rowland decided to put together an F-TR rifle for his eldest daughter, who enjoys competitive shooting. For his daughter, Rowland chose the .223 Rem option because it has less recoil and components are less costly than the .308 Win. Here is Rowland’s account of how he developed a .223 Rem load. For more details (with data charts), read Jeremy’s FULL STORY on Sierra Bullets Blog.

Journey to Find a .223 Rem F-Class Load

by Jeremy Rowland, Reloading Podcast
My oldest daughter has been to several matches with me, and has even competed in several, using her .243. I decided this coming season (2016), she would compete with a .223 Rem in FT/R. Looking for a good starter rifle, I settled on the Savage Axis Heavy Barrel since it has a 1:9″ twist. This would be a great little rifle for her to learn on. The rifle was shot unmodified, as it came from the factory. A Sinclair F-Class Bipod w/micro elevation adjustment was fitted to the front.

Next came finding the components I wanted to use for her match loads. After spending hours and hours running numbers on JBM stability calculator as well as in my iPhone Ballistic AE app, the 69 gr Sierra Tipped MatchKing® (TMK®) looked really good. So that’s what I decided to go with. I jumped in head first and ordered a bulk pack of the Sierra 69 gr TMKs. I had settled on Hodgdon CFE 223 since it shows good velocity. I decided to go with once-fired Lake City brass with CCI BR4 primers.

Next came the testing. I decided to run a ladder test (one shot per charge from min to max looking for the accuracy node). The ladder test ranged from 23.5 grains to 25.6 grains, in 0.3 grain increments.

Bullet: 69 gr Sierra Tipped MatchKing®
Case: Lake City (mixed years, sorted by case capacity)
Primer: CCI BR4
Powder: Hodgdon CFE 223 (one round each from 23.5 to 25.6 grains)
Cartridge OAL: 2.378″
Base to Ogive: 1.933″ (.020″ off lands)

After his ladder test, Rowland settled on a load of 25.2 grains of Hodgdon CFE 223. He then fine-tuned his load with different seating depths: “I loaded up 5 rounds each at .020″ off lands, .015″ off lands, .010″ off lands, and .005″ off the lands. Here are the results from the best group for OAL/Ogive fine tuning. As you can see, I think I’ve found a winner in these 69 gr Sierra Tipped MatchKings.”
