Soon after Lapua released the 6.5×47 cartridge, wildcatters recognized the potential of a necked-down 6mm version of the case. The 6-6.5×47 has emerged as a great, do-it-all cartridge that performs well in High Power competition, 600- and 1000-yard benchrest, and PRS tactical matches. But the 6-6.5×47 is not just for paper-punching. An efficient cartridge with great inherent accuracy, the 6-6.5×47 can be an excellent, flat-shooting, long-range varmint round. Here we feature Stan Stewart’s BAT-actioned 6-6.5×47 varminter. Fitted with a Krieger 1:10″ barrel, Stan’s rifle excels with a wide variety of varmint bullets. Whether driving 70-grainers at 3700 fps, or pushing the Berger 88gr High-BC FB bullet at 3400 fps, this 6-6.5×47 delivers half-MOA (or better) accuracy, in a well-balanced, easy-handling rifle.
The 6-6.5×47 for Precision Long-Range Varminting
The rifle carries a 12-42x56mm Nightforce NSX in Nightforce rings “hand-lapped for optimal fit/alignment”.
‘Seller’s Remorse’ Spurs 6mm Project Report by Stan Stewart
After selling my 6mm Remington Ackley Improved a couple of years ago and wishing I hadn’t, I begun to think about a new custom rifle for work on Prairie Dog towns and New York wood chucks at 600+ yards. I have a .223 AR and 22-250 for medium ranges but I missed my 6mm AI for long-range work so I started asking questions.
The 22-250 is a fine chambering, but it is hard on barrels, and I think the 6mms may have an accuracy edge out past 400 yards. Also, shooters today enjoy a vast collection of really great 6mm bullets. Barrel life and bullet options were two main reasons I decided to build a 6mm rather than another .224-caliber gun. But the question remained… what 6mm chambering to choose?
I started doing serious research on the 6-6.5×47. I received a lot of good advice from AccurateShooter.com and other websites on the pros and cons. I also talked to gunsmiths — quite a few recommended the new cartridge as well. Some of the cartridge attributes I liked was the small rifle primer, enough case capacity to efficiently reach 3700 fps with a 70gr bullet and 3400 fps with an 85-grainer without being terribly over-bore. Most important was the 6-6.5×47’s reputation for inherent accuracy without being finicky like my 6mm AI. So, having chosen my cartridge, I started asking for gunsmith recommendations. Again the folks on the AccurateShooter.com Forum were very helpful. After many conversations I settled on Dave Bruno in Dayton, Pennsylvania. He was a good choice.
Putting Together the New Rig with Premium Components
From the get-go, I knew I wanted a BAT action and Krieger barrel. BAT Machine and Krieger Barrels enjoy a great reputation in the shooting industry. BATs are beautifully-machined, smooth, and strong. Krieger cut-rifled barrels are known for dependable accuracy and long barrel life. While many 6-6.5×47 shooters choose an 8-twist barrel to shoot the 100-108gr bullets, I would be using smaller, varmint-weight bullets, so I selected a 1:10″ twist Krieger. This would allow me to shoot bullets from 60 grains up to 90 grains. Dave chambered the barrel with a .269″ neck and fluted the barrel to save weight. I also had Dave install a Vais muzzle brake. Dave fitted the BAT with a 2 oz. Jewell trigger, mounted a +20 MOA scope rail, then pillar-bedded the BAT into a McMillan Hunter-Class-style fiberglass stock.
Load Development for Varminting
I had selected a few powders and bullets recommended by other 6-6.5×47 shooters and started by seating all the bullets .005″ off the lands. The powders I selected were Varget, Vihtavuori N-550, and Reloder 15.
I was very pleased with the 88gr Bergers. In initial testing, they grouped well and I was able to drive them to 3400 fps easily. As I wanted a gun for long-range varmint work, I was hoping the 1:10″-twist barrel would provide enough stability for the heavier weight bullets. It did — the 10-twist worked great! I was able to shoot the lighter weight bullets and the 88s were superb. With a BC of 0.391, leaving the barrel at 3400, these bullets were still traveling at 2600 fps at 600 yards!
I did a lot of testing, recording group sizes for a variety of different bullets (see below) and powders. With group size/velocity data in a spreadsheet I was able to “crunch the numbers” and choose my preferred loads. The data drew a clear picture of what the rifle shot best. Here is a chart showing comparative group sizes, arranged by bullet type. On the last three lines, powders are listed by average for all bullets.
Choosing a Varmint Bullet for Precision and Performance
Stan Stewart didn’t just grab a box of bullets off the shelf and head off to the varmint fields. He researched a broad selection of varmint bullets suitable for a 10-twist barrel. He did extensive group testing with a wide range of bullets from 70 grains to 90 grains. Shown below is a “line-up” of some of the bullets Stan tested in his gun.
Stan logged all load data, velocities, and group sizes in a very detailed Excel spreadsheet. Stan’s testing revealed that the light bullets delivered superb accuracy, but they were less than ideal for long shots out past 400 yards. Stan tried the Bart’s 70, Sierra 70 BlitzKing, Berger 80, Hornady 87, Berger 88 Lo-Drag, and Berger 90. Among these choices the Berger 88-grainer was the clear winner for long range (see test targets at right). With an 0.391 BC, this unique “Match Varmint High-BC Flat-Base” offers good ballistics, and high velocities. Stan’s average group size with the 88s was 0.40 inches, bettered only by the Bart’s 70-grainer. Stan’s 6-6.5×47 can launch the Berger 88s at a healthy 3400 fps, providing a highly accurate, flat-shooting solution.
Initially, Stan had high hopes for the Hornady 87-grain V-Max. Stan told us “I also tried the 87 gr Hornady but they didn’t perform to expectations. I am a big Hornady fan but these bullets varied in weight and just didn’t want to group well.” [Editor’s Note: While many varmint shooters have had great luck with the Hornady 87gr V-Max, this is not the first report we’ve received of disappointing results with these bullets. In the Editor’s own 8-twist 6BR, the 87s never shot as well as Bergers, Lapuas, or Sierras in the 85-90 grain range.]
Final Thoughts on the 6-6.5×47 Lapua
I have owned three rifles chambered in 22-250 and will always own a rifle in this caliber because it is inherently accurate and drives a 50gr bullet at 3800 fps. No question the 22-250 can be deadly out to 500 yards. However, I’ve found that shooting past 400 yards with the light bullets is difficult if there is any wind at all. That’s why I liked my 6mm AI for those longer shots and why I decided on the 6-6.5×47 Lapua. I couldn’t be happier with my choice. The only thing that could make it better is if Lapua would produce the 6-6.5×47 as an “official” factory 6mm cartridge with 6mm necks right out of the box. But overall, I am very happy with the cartridge, and I thank Dave Bruno for producing a superbly accurate varmint rifle.
For this Saturday Showcase, we feature some top-tier products that have set new standards for quality and effectiveness. First off is the impressive new NEXUS single-stage press from Short Action Customs. Then we feature Bix’N Andy triggers, which have found favor with competitors in many disciplines from short range Benchrest to ELR competition. Now that Jewell triggers are becoming harder to source, Bix’N Andy units will be seen on more rifles than ever. For those who turn case-necks, we feature the remarkable IDOD machine from F-Class Products — simply the best automated neck-turner ever created.
As a bonus we offer two very informative interviews from SHOT Show 2024. The first covers the product line at Bullet Central, while the second reviews the latest and greatest rifle actions from BAT Machine.
Short Action Customs NEXUS Press
One of the most notable new products at SHOT Show 2024 was an innovative single-stage press from Short Action Customs (SAC). The new $775 NEXUS press has impressive design features. The NEXUS Press boasts dual cam-over pucks, which precisely stop the movement of the floating die block. SAC explains: “We wanted to have the Nexus press cam-over independently of the shell holder. Every single cycle of the press, your hard cam-over pucks limits the travel, which gives you the same amount of cam over every single cycle.” The press can adapt to various diameter dies with floating inserts in the top section (see video). The NEXUS also has a floating shell holder system, which is quick change and tool-less. SAC states that this shell holder system “allows .010″ more sizing than all other shell holders on the market”.
Bix’N Andy Triggers
German-made Bix’N Andy triggers, available from BulletCentral.com, are among the very best you can buy. Available in both single-stage and two-stage designs, Bix’N Andy triggers are extremely precise, repeatable, and smooth. The unique internal, friction-reducing roller ball system allows for extremely low reset force, yielding an ultra-crisp let-off. Bix’N Andy triggers can be fitted with a variety of trigger shoes according to shooter preference. Bullet Central is currently the exclusive official USA importer for Bix’N Andy triggers.
Bryan Blake, a very clever machinist and gunsmith, has created an ultra-precise and speedy neck-turning machine. Bryan, who runs Blake Machine, Blake Barrel, and F-Class Products has created a system that uses twin precision cutter tips to turn case necks inside and out quickly and efficiently, with superior precision. This advanced IDOD Neck Turning Machine holds cases securely in a precision-machined spindle attached to an electric motor. Twin blades move precisely during the cutting process, milling the necks inside and out. The turned necks come out perfect every time, with the shoulders trimmed exactly (with doughnut removed) as well.
If you turn hundreds of cases during a shooting season, you may want to buy an IDOD from F-Class Products. The secret to the efficiency of the Blake IDOD is a vibration-free motor, high-mass case-holder, precision OD/ID-adjustable cutter, along with an advanced tracking system that moves the cutter heads towards the case neck (and back again) with absolute, 100% repeatable precision.

Here is Ernie Bishop’s pride and joy, a specialty pistol nicknamed “Batman” because the black carbon-fiber stock looks like the Batmobile. This is one sophisticated handgun. Complete with scope, the Batman pistol weighs under 7.5 pounds, thanks to the ultra-light stock. The carbon stock is 6 inches wide at the fore-end, yet weighs just one pound. Ernie tells us: “This gun shoots amazing and is easy to shoot especially with my SEB MAX Rest.” After these photos were taken, Ernie added a “field-usable rear-grip stock so [he could] shoot it prone from a bipod as well.”
The Batman pistol is chambered for the 6mm “Long Dasher”, a 6mm 40°-shouldered variant of the 6.5×47 Lapua. Ernie loads Berger 105gr Hybrid bullets pushed by Hodgdon H4350 powder.
Gun Specifications The gun, crafted by Eric Wallance of Nawaka Firearms, features an XP-100 action, Jewell trigger, and 15″-long, Brux 1:8″-twist barrel with aluminum muzzle brake. Interestingly, this gun does not have a traditional recoil lug. Instead, gunsmith Wallace milled out a lug from the bottom of the XP-100 action to save weight. On top of the action, the rig carries a Sightron Inc S-III 6-24X56mm scope in Kelbly rings on a custom +20 MOA rail.
Long Dasher Wildcat
Shown at right is a “Long Dasher” 40° wildcat created by Forum member Sunbuilder. This is very similar to Ernie Bishop’s chambering, though there may be small variations related to reamer design (such as freebore). Sunbuilder’s 6-6.5×47 Improved (aka “Long Dasher”) reamer was made by Dave Kiff of Pacific, Tool & Gauge. This wildcat cartridge adds about 2.0 grains capacity to the 6.5×47 necked down to 6mm. The case certainly is impressive with that 40° shoulder. We’re just waiting for the tactical guys to starting run this improved cartridge with its original 6.5mm bore.
Here are three FIVE-shot groups at 500 yards, shot by Ernie’s Batman pistol:

Many short-range Benchresters have thought about converting their 6 PPC to shoot a 30BR for score matches, or a Dasher for mid-range (or even 1000-yard) games. That way you have a rifle that does double duty, giving you the most bang for your buck. Though an action with a PPC bolt won’t normally work with 30BR/6BR/Dasher cases with their larger .308-class rim (0.4728″ diameter), there is a pretty easy solution that allows you to cycle these bigger cartridges with a 6PPC-style bolt (designed to fit .220 Russian rims).
“Rebating case rims … lets you shoot a 30BR in score matches using your PPC action. All you need is a new barrel. This saves buying another bolt, receiver, or rifle.” — Butch Lambert
Butch Lambert of ShadeTree Engineering provided this tip. Butch notes that many 6 PPC benchrest group shooters also enjoy shooting in score matches. But to be really competitive in the BR for score game, that means shooting a 30BR, which has a wider, .308-class rim (0.4728″ diameter). Likewise, if you want to compete in 600-yard registered BR events or in varmint matches, you probably want to run a bigger case, such as the 6BR, 6mm Dasher, or 6-6.5×47. Those cartridges also have the larger 0.4728″ rims.
Rebate Your 30 BR Rims
To convert a PPC-boltface action to shoot bigger cases you can spend a ton of money to buy a new bolt. That can cost hundreds of dollars. The simpler solution is to turn down the diameter of the larger cases on a lathe. Butch explains: “We’ve seen plenty of interest in rebating case rims. This lets you shoot a 30BR in score matches using your PPC action. All you need is a new barrel. This saves buying another bolt, receiver, or rifle if you have a PPC boltface. Anyone who has access to a lathe can do this job pretty easily. Yesterday I turned 150 case in about an hour.”

Here is what high-end hunters have been requesting for years — an ultra-lightweight mag-fed action with Benchrest-grade smoothness, engineering, and craftsmanship. BAT Machine has just introduced two impressive new aluminum/steel hybrid repeater actions — the Bumblebee (short action) and the Vampire (long action). These are REALLY light. BAT states 23.8 ounces for the Bumblebee, and Alex Wheeler reports the Vampire is 25.3 ounces. So you get titanium-class weight savings without the titanium hassles.
Both the Bumblebee ($1699 MSRP) and the Vampire ($1765 MSRP) are aluminum/steel designs with integral recoil lugs and +20 MOA Picatinny rail segments. Though they are flat-bottom actions, both are designed to fit most Remington 700-pattern stocks. Gunsmith Alex Wheeler says: “This action shape should be very stable in the bedding — you just need to square up the inlet.”
Both the Vampire and Bumblebee actions feature a modular bolt. BAT does the modular bolt differently than anyone else, and very cleverly. This design allows easier bolt face changes and spring changes. Internal maintenance is also easier. Bat bolts also run super smoothly. Alex Wheeler reports “the Vampire action is very smooth — it feels just like BAT’s all-steel actions.”
Vampire action photos courtesy WheelerAccuracy.com. The Vampire fits a 4″-long CFE-09 magazine box.
Alex Wheeler got one of the first Vampire actions, and he was impressed. This is a long-action repeater, with standard or Magnum bolt. Alex says the mating of steel and aluminum was superb: “I have checked it for straightness and lug contact. It’s very good. I’m impressed with how straight they got this insert.”
Bumblebee Action — State-of-the-Art Lightweight Hunting Action
If you are seeking a very lightweight action with Benchrest-quality smoothness and precision fit/finish, consider the Bumblebee. Weighing under 24 ounces, this new Bumblebee short action may be perfect for hunters, varminters, and tactical shooters who desire a light weight, premium quality action. The new Bumblebee is designed to use 700 Short Action bottom metal. Combining steel and aluminum, the Bumblebee combines 4140 Chromoly Steel and 7076-T6 Aluminum to achieve strength and rigidity at a weight rivaling titanium. According to BAT, the Bumblebee’s advance design makes it “31%-42% stiffer than light weight steel actions and over 130% stiffer than round Titanium actions.”
Bumblebee Action Features and Specifications:
— Action weight is 23.8 oz. as configured in photos (11.4 oz. lighter than BAT VR/TR actions)
— Weight comparable to Titanium actions after including Picatinny rails, recoil lugs, and fasteners
— 31%-42% stiffer than lightweight steel actions and over 130% stiffer than round Titanium actions
— Action body made with aircraft-grade billet 7075-T6 Aluminum and hardened 4140 Chromoly Steel
— Integral +20 MOA Picatinny two-section rail standard
— Modular bolt for lower cost bolt face changes
— .070″ firing pin diameter for maximum accuracy and reliable ignition
— Standard medium aluminum bolt knob, 5/16-24 thread
— LiFe Melonite-treated firing pin, bolt and shroud for smooth bolt movement and low maintenance
— Extended extraction cam for smooth bolt opening
— Uses Remington 700 SA trigger components and bottom metal
— Right-hand and left-hand versions
— Barrel tenon is 1.062 x 18 tpi (CLICK HERE for blueprint)

If you have ANY interest in custom rifle actions, you MUST watch this video from UltimateReloader.com. Folks, definitely watch the video — it is VERY informative! To produce this video, Ultimate Reloader’s Gavin Gear visited the BAT Machine facility in Post Falls, Idaho, and interviewed BAT owner Bruce Thom.
In the video Bruce Thom demonstrates how BAT Machine actions are created from start to finish. Bruce shows every stage of the process, employing multiple high-tech machines. It’s impressive — Forum members say that this is a “must-watch” video. Gunsmith Jackie Schmidt noted: “Great Video. Even though I have been in the machine shop business for 50 years, I still marvel at the new innovations in precision machining. Bruce has a very down-to-earth, common sense approach to explaining what to many seems like machining wizardry.” And Mark T. posted: “Watched it last night. Excellent video and excellent machining practices — precision from beginning to end.”

For further explanation of the action production processes, with step-by-step listing of how receivers and bolt assemblies are created, read Gavin Gear’s full BAT Machine Article on UltimateReloader.com.
BAT Machine Company Was Started 29 Years Ago
Back in 1991, Bruce Thom started BAT Machine Company, which was incorporated later in 1996. Bruce’s shop stared with manual machines, quickly moving to CNC machines later in the 1990s. BAT Machine quickly achieved a following among benchrest shooters for crafting superb actions that exhibited flawless function and superb machining. Those qualities, benchrest competitors realized, helped produce tiny groups, win matches, and set benchrest records. BAT Machine now makes rifle actions for a wide variety of disciplines: F-Class, PRS, ELR, hunting, and of course short- and long-range benchrest.
BAT Action Body Machining Stages
As shown in the video, here are the major stages for the fabrication of a BAT Machine receiver body:
1. Start: raw 17-4 stainless round bar (higher toughness than typical barrel/receiver steel)
2. Heat treat
3. Bore central hole (for EDM wire), face ends
4. EDM machining (cut bore and raceways)
5. True OD, cut receiver threads and lug seats
6. Cut tang and related features
7. Finish machining including body OD, integral lug (if equipped)
Final Production Stages — Polishing and Deburring
After the receiver body and bolt are machined, they go through a deburring and polishing process.
In the image above you can see the stages. At left is a receiver body straight from machining. Some hand work is typically performed to break interior edges that are sharp from machining. In the center, the receiver shows can see the initial polish stage. During this stage, machining marks are removed by coarse polishing. Additionally for receivers that will be nitrided, that will be done next. But for actions that are NOT nitrided, a final polish brings the parts up to a high luster, as show on the right.
After polish (and nitriding if that applies) the bolts and receivers get a finish assembly, and testing for proper smooth functioning. The receivers are then registered with the ATF and shipped to the customer.

With all the noise lately about the 6.5 Creedmoor, it’s easy to forget that before we had the Creedmoor, we had another accurate, efficient mid-sized cartridge, the 6.5×47 Lapua. Just as the 6.5 Creedmoor inspired the 6mm Creedmoor, the 6.5×47 Lapua has been successfully necked-down to 6mm (.243) for a 6-6.5×47 variant. This has worked great in a number of roles — benchrest, varminting, and tactical/PRS. This article, from a few seasons back, shows how the 6-6.5×47 Lapua can be successfully packaged as an accurate, potent 6mm varminter.
The 6-6.5×47 Lapua for Precision Long-Range Varminting
Report by Stan Stewart
6mm AI ‘Sellers Remorse’ Spurs New 6mm Project
After selling my 6mm Remington Ackley Improved a couple of years ago and wishing I had not, I thought about a new customer rifle for work on Prairie Dog towns and New York wood chucks at 600+ yards. I have a .223 AR and 22-250 for medium ranges but I missed my 6mm AI for long-range work. The 22-250 is a fine chambering, but it is hard on barrels, and I think the 6mms may have an accuracy edge out past 400 yards. Also, shooters today enjoy a vast collection of really great 6mm bullets. Barrel life and bullet ooptions were two main reasons I decided to build a 6mm rather that another .224-caliber gun. But the question remained — what 6mm chambering to choose? Although I missed my 6mm AI, I did not miss fire-forming the brass, so when I learned about the 6-6.5×47 Lapua, a wildcat case easily formed by necking down the parent 6.5×47 case, I thought this might be the answer.
I started doing serious research on the 6-6.5×47 Lapua. I received a lot of good advice from AccurateShooter.com and other websites on the pros and cons of the new cartridge. Most reports were positive. I also talked to gunsmiths — quite a few recommended the new cartridge as well. Some of the cartridge attributes I liked were the small rifle primer, enough case capacity to efficiently reach 3700 fps with a 70gr bullet and 3400 fps with an 85-grain, without being terribly over-bore.
Most important was the 6-6.5×47’s reputation for inherent accuracy without being finicky like my 6mm AI (my experience). So, having chosen my cartridge, I started asking for gunsmith recommendations. Again the folks on the AccurateShooter Forum were very helpful. After many conversations I settled on Dave Bruno in Dayton, Pennsylvania. He was a good choice. After working with Dave on this project, I could not be happier. He was very helpful considering this was my first complete custom gun.
Putting Together the New Rig with Premium Components
From the get-go, I knew I wanted a BAT action and Krieger barrel. BAT Machine and Krieger Barrels enjoy a great reputation in the shooting industry. BATs are beautifully machined, smooth, and strong. Krieger cut-rifled barrels are known for dependable accuracy and long barrel life. While many 6-6.5×47 shooters choose a 8-twist barrel to shoot the 100-108gr bullets, I would be using smaller, varmint-weight bullets, so I selected a 1:10″-twist Krieger. This would allow me to shoot bullets from 60 grains up to 90 grains. Dave chambered the barrel with an 0.269″ neck and fluted the barrel to save weight. I also had Dave install a Vais muzzle brake. The Vais brake is more expensive than some others, but it is a proven product. Dave fitted the BAT with a 2 oz. Jewell trigger, mounted with a +20 MOA scope rail, then pillar-bedded the BAT into a McMillan Hunter-Class-style fiberglass stock. The scope is a 12-42x56mm Nightforce NSX, mounted in a set of Nightforce rings I hand-lapped for better contact.
Load Development for Varminting
I had selected a few powders and bullets recommended by other 6-6.5×47 shooters and started by seating all the bullets .005″ off the lands. The powders I selected were Varget, Vihtavuori N550, and Reloder 15.
I was very pleased with the 88gr Bergers. In initial testing, they grouped well and I was able to drive them to 3400 fps easily. As I wanted a gun for long-range varmint work, I was hoping the 10-twist barrel would provide enough stability for the heavier weight bullets. It did — the 10-twist worked great! I was able to shoot the lighter weight bullets very well and the 88s were superb. With a BC of 0.391, leaving the barrel at 3400 fps, these bullets were still traveling at 2600 fps at 600 yards!
I did wonder how well the 88s would work on varmints given their small meplats (and limited expansion). A call to Berger reassured me the 88s should work fine on small varmints. The test came last summer when I made a trip to NY and got to visit my old Chuck hunting farms with my new rifle and old hunting buddy. The longest shot we had was only 300 yards, but the Berger 88s did great. None of the eight critters we nailed so much as wiggled after they were hit.
I did a lot of testing, recording group sizes for a variety of different bullets and powders. With all the data collected in a spreadsheet, I was able to “crunch the numbers”, and that helped me choose my preferred loads. By looking at the average group size for the individual bullets and powders, the data drew a clear picture of what the rifle shot best. Below is a chart showing comparative group sizes, arranged by both bullet type and powder brand.
Helpful “How-To” Maintenance Videos from BAT
BAT Machine’s website features an extensive Video Archive with a selection of helpful videos for custom action owners. Among BAT’s collection of videos, you’ll find informative clips covering about bolts, ejectors, action maintenance, and other technical matters. Here are two examples:

One thing that people might easily miss is the large spreadsheet that details the specs of all BAT Machine actions. To download that .xlsx spreadsheet to your hard drive, Right Click (and “Save As”) this link: ACTION CONFIGURATION PART LIST. After opening the spreadsheet, on the “ACTION” worksheet, you’ll find action model, body shape, weight, bolt faces available, and tenon spec among several other items. Note that there are two worksheet tabs (look down at the bottom left). Use these spreadsheet tabs to switch between “Action” and “Accessories”.
Also, on the BAT website FAQ page, you’ll find prints for barrel tenon machining, firing pin sizes, torque specs, and tons of other very helpful info. This is well worth a look. — ELR Researcher.

A beefy, new BAT action will debut at SHOT Show 2017. The new BAT TR Tactical action will be showcased by BulletCentral.com at Booth #2963. Notably, Bruce Thom, founder of BAT Machine, will be at the booth on Wednesday, January 18, 2017. Stop by to meet Bruce and learn more about this action.
Designed from the ground up for tactical and PRS shooters, the new TR action features a very stiff, robust body that still fits a Remington 700 inlet. The TR’s bolt is different than on BAT’s benchrest actions, so the TR runs better in dusty conditions and with extended strings of fire. This new action is fully compatible with Accuracy International double-stack magazines.

Final Thoughts on the 6-6.5×47 Lapua
The gun, crafted by Eric Wallance of Nawaka Firearms, features an XP-100 action, Jewell trigger, and 15″-long, Brux 1:8″-twist barrel with aluminum muzzle brake. Interestingly, this gun does not have a traditional recoil lug. Instead, gunsmith Wallace milled out a lug from the bottom of the XP-100 action to save weight. On top of the action, the rig carries a Sightron Inc S-III 6-24X56mm scope in Kelbly rings on a custom +20 MOA rail.
