Sometimes you’ll get a barrel that doesn’t stabilize bullets the way you’d anticipate, based on the stated (or presumed) twist rate. A barrel might have 1:10″ stamped on the side but it is, in truth, a 1:10.5″ twist or even a 1:9.5″. Cut-rifled barrels, such as Kriegers and Bartleins, normally hold very true to the specified twist rate. With buttoned barrels, due to the nature of the rifling process, there’s a greater chance of a small variation in twist rate. And yes, factory barrels can be slightly out of spec as well.
After buying a new barrel, you should determine the true twist rate BEFORE you start load development. You don’t want to invest in a large supply of expensive bullets only to find that that won’t stabilize because your “8 twist” barrel is really a 1:8.5″. Sinclair International provides a simple procedure for determining the actual twist rate of your barrel.
Sinclair’s Simple Twist Rate Measurement Method
If are unsure of the twist rate of the barrel, you can measure it yourself in a couple of minutes. You need a good cleaning rod with a rotating handle and a jag with a fairly tight fitting patch. Utilize a rod guide if you are accessing the barrel through the breech or a muzzle guide if you are going to come in from the muzzle end. Make sure the rod rotates freely in the handle under load. Start the patch into the barrel for a few inches and then stop. Put a piece of tape at the back of the rod by the handle (like a flag) or mark the rod in some way. Measure how much of the rod is still protruding from the rod guide. You can either measure from the rod guide or muzzle guide back to the flag or to a spot on the handle. Next, continue to push the rod in until the mark or tape flag has made one complete revolution. Re-measure the amount of rod that is left sticking out of the barrel. Use the same reference marks as you did on the first measurement. Next, subtract this measurement from the first measurement. This number is the twist rate. For example, if the rod has 24 inches remaining at the start and 16 inches remain after making one revolution, you have 8 inches of travel, thus a 1:8 twist barrel.
Determining Barrel Twist Rate Empirically
Twist rate is defined as the distance in inches of barrel that the rifling takes to make one complete revolution. An example would be a 1:10″ twist rate. A 1:10″ barrel has rifling that makes one complete revolution in 10 inches of barrel length. Rifle manufacturers usually publish twist rates for their standard rifle offerings and custom barrels are always ordered by caliber, contour, and twist rate. If you are having a custom barrel chambered you can ask the gunsmith to mark the barrel with the twist rate.

Five targets, each with FIVE shots in essentially one hole. The events of this story happened two years ago. We are reprising our report because this five-target Aggregate arguably represents the most impressive feat of 100-yard accuracy in the history of marksmanship on this planet.
Check out those five targets. The Aggregate (average) of all five targets is a tiny 0.0840 inches! These were shot by Gary Ocock at 100 yards in a California benchrest match on August 6, 2017. Though Gary’s 0.0840 Agg beats existing records, this was not a “sanctioned” match, so Gary’s killer Agg will NOT be submitted for IBS or NBRSA records. So, sadly, the Agg won’t appear in the record books, but this remains a spectacular, verified feat of rifle accuracy, accomplished in competition.
The argument can be made that this is the Most Accurate Gun Ever Built. As far as we can determine, no one has ever shot a smaller 5-target Agg anywhere, at any time.
The Unlimited Benchrest Record That Will Never Be (Official)
Report by Boyd Allen
Gary Ocock’s stunning unlimited Aggregate is beyond amazing. That’s an average of five, 5-shot groups of .0840. Shot under sanctioned match rules, but at an unsanctioned 100-yard fun match, this Aggregate is well under the current 100-yard official records of the IBS (.1386), and the NBRSA (.1242). The fourth of the five groups measured a minuscule .018, less than half the size of the existing NBRSA Unlimited record of .049 (also shot by Gary). Check it out:
When the top 15 shooters all post teen Aggs, conditions must be pretty favorable. However there were some light switchy winds — Gary said that he shot better in the left to right condition.
GUN SPECIFICATIONS
Ocock’s red Jay Young Unlimited Railgun features one major difference from Young’s typical Railgun designs. The bottom of the barrel block is integral with the top (moving part), of the gun. The barrel is Ocock’s usual 1:13.5″-twist Krieger chambered for the 6 PPC. The BAT Neuvo action* is unusual in that its lugs are horizontal at lock-up instead of the usual vertical. With horizontal lugs, both lugs maintain contact with their abutments when the action is cocked. In the more normal configuration when cocked the top lug is forced off of its seat by a combination of the angle of the trigger cocking piece interface, the pressure of the striker spring, and bolt clearance at the rear of the action.
LOAD SPECIFICATIONS
Gary shot this remarkable Agg with well-used brass, Vihtavuori N133 powder, and self-made 66gr BT bullets** seated at “jam”. This amazing Agg was shot on the second day of a 2-day Unlimited Benchrest match. On Day 1 Gary had experimented with various loads using both surplus IMR 8208 and Vihtavuori N133, but was not satisfied with the results. For his first group on Day 2, Gary tried a light load of N133. After seeing the result, however, he decided to go to the other extreme — a super stout N133 load — with the same powder. As you can see, Gary’s willingness to experiment paid off.
Notably, Gary used light neck tension. Ocock found that for these bullets and this barrel, light neck tension worked best (contrary to “normal” N133 benchrest practice). Ocock used a bushing that only produces .001″ difference between the diameters of sized and loaded case necks.
Comment on Ocock’s Achievement
Congratulations to Gary Ocock for superb shooting (and smart loading). Even though the match was not sanctioned (so the Agg will never be a record), Ocock has raised the bar very high, and given us a new standard of ultimate accuracy.
Though this 0.0840 Aggregate and 0.018 group will never go into the record group, they are still noteworthy. There’s virtually no doubt that they would have survived inspection by any record committee. Except for the lack of fixed backers, an IBS requirement (for detecting cross-fires), all other conditions were met for an officially-sanctioned match.
*The new BAT Neuvo actions are the result of a collaboration between Dwight Scott, and Bruce Thom, featuring Dwight’s ideas and BAT’s proven manufacturing expertise.
** Ocock shot his own, boat-tail match bullets, made with George Ulrich-crafted dies using Hood cores. Although he said that it had been a while since he had weighed any, his best guess was that they weigh something around 66.5 grains.

Today’s Sunday GunDay story features Corbin Shell’s remarkable, record-setting .416 Barrett. With a 40″ Krieger barrel secured in a massive barrel block, this is definitely a big boomer!
Last month, Forum member Corbin Shell set a new Extreme Long Range (ELR) record. With no sighters or warm-up shots, Corbin put three (3) shots on a 36″ x 36″ steel plate at 2118 yards, establishing a new Cold Bore ELR World Record. The range was verified with three rangefinders and witnessed by 20+ awestruck shooters. Applied Ballistics reports: “There is a new official ELR World Record. 2118 yards. 3 for 3 cold bore.” This was also recognized as a record by the FCSA (Fifty Caliber Shooting Association).*
This record was set at the ELR Southeast Shootout held at the Arena Training Facility in Blakely, Georgia, on March 2, 2019. The World Record attempt was made in compliance with all ELR Central Rules.
Corbin Shell (on right) stands next to Joe Burdick, match director. That’s three hits on 36″ x 36″ plate.
ELR Ain’t Cheap — $6.55 Cost per Shot
Corbin told us: “Each round fired cost approximately $6.55. The breakdown is as follows: bullet $3.05, powder $0.80, primer $0.50, cartridge case $1.00 (based on five firings), barrel wear $1.20 per shot based on 1000 rounds of barrel life. Hitting steel at distance: PRICELESS!”
ELR Record .416 Barrett Rifle Components
Action: BAT .50 caliber EX, multi-flat, with hard coat finish, extra CheyTac bolt. Barrel: Krieger cut-rifled, .416 caliber, 40″ finish length, 1:9″ twist. Barrel Block: Doyle Anglin Dixie Gunworks, integral Picatinny rail. Muzzle Brake: Ryan Pierce 5-port magnum. Stock: Designed and fabricated by Doyle Anglin, Dixie Gunworks. Obeche laminate, Indian Blanket color scheme. 48″ long excluding butt hardware. Butt and Cheekpiece Hardware: Master Class/Alex Sitman, extended rods. Scope: Sightron SIII 6-24x50mm MOA reticle item #25127. 100 MOA elevation/windage. Bipod: Duplin Rifles by Clint Cooper. Weight: One pound, 2 ounces. Gunsmith: Rifle builder was Doyle Anglin, Dixie Gunworks, Winder, GA.
If you want to learn more about this record-setting rifle, Corbin has prepared a 6-page project history describing all the components and explaining how the rifle was constructed. This Build Document also contains a wealth of information about loading for the .416 Barrett cartridge.
Conditions During Record:
Corbin tells us: “This was shot in Blakely, Georgia at the Arena Training Facility in good Ole dense Southern air. Here are the atmospheric conditions when I shot: 70 degree temperature, 29.70-29.80 inches of mercury, 82% humidity, 1211 Density Altitude (DA).”
Corbin noted that the unique barrel block with rail helps with ELR Optics: “This custom-made barrel block is drilled length wise to reduce weight. It incorporates an integral Picatinny rail which… facilitates mounting of … the Tacom Charlie/Delta TARAC prism system, without the need to bridge mount.” Charlie/Delta TARAC units effectively offset the view that comes into the scope, providing up to 625 MOA elevation.
ELR Cold Bore Shot Record Rules
Congratulations to the new ELR World Record Holder Corbin Shell. The record now stands at 2118 yards. This record was shot under a very specific set of rules established by ELR Central and industry leaders. For more ELR record information, go to ELRCentral.com. All ELR World Record results can be seen on the ELR Central’sEvent Results Page.
* Prior to Corbin Shell’s GA record, David Tubb shot a 2200-yard, 3-shot group that has been recognized as a FCSA record. However, because David had made a same-day attempt, within minutes, with a different rifle, this did not comply with the ELR Central Rules. So, at this time only Corbin Shell is recognized as the ELR Central World Record Holder.

Looking 1000 yards downrange at the Deep Creek Range outside Missoula, Montana.
On Facebook recently, we saw an eye-catching rifle. Owned by top 1000-yard competitor (and past IBS Champ) Tom Mousel, this rifle was smithed by Alex Wheeler of Wheeler Accuracy. This rig features the McMillan-crafted Wheeler LRB stock with adjustable keel. It also has BAT Machine’s very impressive new Neuvo LR (aka “Neuvo M”) action, serial number LR0001. The Neuvo LR has some important design features — horizontal lug orientation, full-diameter bolt body, and advanced fire control system. More about those features below.
This gun is a shooter. Tom has already shot a 1.5″ four-shot group at 1000 yards. How does he do that? First you need a great barrel, great bullets, and superior hand-loading skills. But then it comes down to great gun-handling. You can see that in the video below. NOTE to ALL Long-Range Benchrest shooters — Watch this video! You’ll definitely learn from watching Tom shoot — he’s one of the best in the business.
Tom Mousel shoots 1000-yard ladder test with first-released Neuvo LR action, SN LR0001.
Rifle chambering is 6BR Ackley (6BRA) in 28″ Krieger barrel.
Rifle Components and Build INFO:
This rifle has a BAT Neuvo LR (aka Neuvo “M”) action glued and screwed into the LRB stock using a special bedding block, a Boyd Allen concept that Tom has requested to use on every future build. The 28″ Krieger 1:8″-twist HV barrel was indexed using a little different method than most use. It is “panning out well” says Alex, who adds: “So far it has shot [multiple low ones] with two barrels and three different bullet types. This rifle is definitely one of the better shooters I have seen.” We’d agree — owner Tom Mousel has had a 1.5″ 4-shot group at 1000 yards in testing, plus some “zero” 3-shot groups at 100 yards.
Chambering is the 6mmBR Ackley (6BRA). The stock is a Wheeler/McMillan LRB stock with vivid orange and black paint job. It features an adjustable keel in the rear. Trigger is a Bix N Andy unit from Bullets.com.
This BAT Neuvo LR action is a Left-loading Drop Port. Cartridges eject out the bottom of the action.
BAT Machine Neuvo Long Range “M” Action
This is the “Long Range” version of the BAT Neuvo. Dwight Scott and Chris Harris were the original inspiration. I worked with Chris to come up with a version for long range. The main differences for the LR Neuvo (compared to the shorter Neuvo) are this has integral lug and rail, with flat bottom and sides for better bedding. The BAT Neuvo LR is available in drop port, dual port, and single port as well as magnum.
Take a look at the bolt. Notice the lug orientation and full diameter bolt body. There are no bolt raceways in the action and the two lugs sit HORIZONTALLY when the bolt is closed — that’s different than the vast majority of other two-lug actions.
Alex Wheeler says the Neuvo is a winner. He thinks some of the action’s design features really do contribute to enhanced accuracy: “The … fire control (firing pin assembly) carries a lot of energy and has a very “clean” release. This is an excellent design with many small details that combine to deliver superior function. In addition, the full-diameter bolt can be fitted tighter than one with lugways. Also the horizontal lugs may be why we see less vertical stringing in the groups. They are timed perfectly as well.”

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.
Brux Barrels, based in Lodi, Wisconsin, has earned a reputation for producing great-shooting tubes. Brux-made barrels have won their fair share of matches, and set some notable records in the process. A few years back, Rodney Wagner shot the smallest five-shot, 600-yard group (0.336″) in the history of rifle competition, using a Brux barrel chambered for the 6mm Dasher.
Folks often ask us why Brux barrels shoot so well. “What’s the secret?” they ask. We can only answer with what Brux explains on its own website: “To make a cut-rifled barrel you have to start off with the proper ingredients: the best steel available, skill, and experience. Since there are really only two main suppliers of barrel-quality steel, the skill and experience is what really makes a barrel maker stand out.” Here is how Brux’s co-owners, Norman Brux and Ken Liebetrau, explain all the procedures involved in making a Brux cut-rifled barrel:
Brux Barrel-Making Process, Start to Finish
We start out with either 4150 chrome-moly or 416R stainless steel double stress-relieved bar stock. The bar stock starts out at 1-9/32″ in diameter and 20-24 feet long so we cut it to length.
Step two is to rough-contour the outside of the barrel blank in a lathe.
Thirdly, the blank gets mounted into a Barnes gun drill. The cutter bit has holes through which oil or coolant is injected under pressure to allow the evacuation of chips formed during the cutting process. This is called “oil-through” or “coolant-through”. Without this, you wouldn’t want to even attempt drilling a hole 30” long and under ¼” in diameter. The combination of a 3600rpm and good flushing allows us to drill a beautifully straight and centered hole .005” under “land” diameter at a rate of 1” per minute.
Clean the barrel.
Next the blank is sent back to the lathe to machine the finished contour of the outside.
Clean the barrel again.
Now, the blank is sent on to the Pratt & Whitney reamer in which an “oil through” reaming tool is used to cut away the extra .005” left in the drilling process. The reamer makes an extremely accurate bore size and after it is finished the bore will have a better surface finish and will be at the proper “land” diameter.
Clean the barrel again.
In the sixth step we hand lap each barrel to remove any slight tool marks that may have been left by the reamer and inspect every one with a bore scope. If the barrel doesn’t meet our standards for surface finish and tolerance it doesn’t get any further.
Clean the barrel again.
The barrels then go onto the rifling machine which is responsible for cutting the all so familiar grooves in the bore. A caliber/land configuration-specific rifling head is used to progressively shave away small amounts of steel to form the rifling grooves. This is accomplished by simultaneously pulling the rifling head through the reamed blank as the blank is spun at a controlled rate. After each cut, the blank is rotated 90 degrees (for a four-land configuration) and after one full rotation (360 degrees) the rifling head is slightly raised to shave off the next bit of material. This process is repeated until we reach groove diameter.
Clean the barrel again.
Lastly, the barrel is hand-lapped again (to ensure a smooth bore), and a final inspection is performed with the bore scope.
The barrel is cleaned one last time, wrapped, packed, and shipped to [the customer].
Anyone reading this detailed description of the Brux barrel-making process will doubtless come away with a new appreciation for the time, effort, and dedication required to produce a premium match-grade cut-rifled barrel. Obviously, there are no easy shortcuts and great attention to detail is required each step of the way. As shooters we’re lucky that we have barrel-makers so dedicated to their craft.

Report by Des Parr
With every new season, standards in the F-Class game are climbing ever higher. Shooter are improving their skills set while equipment and loading techniques are improving (thanks in part to websites such as this). Evidence of the level of improvement in F-Class shooting comes from the UK, where a talented shooter drilled a new GBFCA record score. One of our rising stars on this side of the pond is F-Open shooter Paul Hill. He hails from England’s wide-open flat lands where the wind blows strongly in from the North Sea and where a shooter must soon learn to read the wind.
At the European Championships held in September at the Bisley ranges, Paul set a new record score at 900 yards — a 100-17V! That’s 17 shots placed in a five-inch circle the size of a CD (compact disc) at over half a mile. [NOTE: At Bisley, the maximum score is FIVE points, not ten points. So the maximum score for 20 shots is 100. Also what Americans call an “X” is called a “V” at Bisley.]
Record Set with Slower Pair Firing Method
Bear in mind the style of shooting here in Great Britain is pair-firing. Under this procedure, each of two competitors shoots alternately, taking turns from shot to shot. Each shooter has 45 seconds to get his shot off. Allowing for the target pullers to do their jobs, this means that each shot can take up to one minute. As Paul was pair firing, he had to concentrate for up to 40 minutes to get all 20 shots off! You can imagine how many times the wind changed course in those 40 minutes — pick-ups, let-offs, changes of angle and direction. Paul had to counter each change and still managed to keep 17 shots in that 5-inch circle!
Paul Hill Sets Record with His First-Ever DIY-Chambered Barrel
What makes this new GBFCA record all the more significant is that Paul did it by barreling his own rifle — and for the first time! By simply taking great care and attention he has chambered and fitted a barrel himself to the very highest standards. Paul chambered the Krieger 1:9″-twist barrel for the .284 Winchester cartridge. His action was a Barnard. The stock is by Joe West.
Record Shot with Lapua 180gr Scenars and Russian Primers
We should note that Paul Hill is a very keen fan of Lapua’s 180gr Scenar-L bullet. It has to be said that this bullet doesn’t have the highest BC, yet whatever it lacks in that department it more than makes up for by being remarkably consistent — and consistency counts for a lot. Paul is also a fan of the Russian KVB-7 primers. His achievement is proof that Lapua Scenars and KVB-7 primers are every bit as good as the premium-priced alternatives. The powder was Vihtavuori N160. [Editor: For its 180gr Scenar-L, Lapua lists a 0.661 G1 BC, and a 0.332 G7 BC. Those numbers may not top the charts, but they are still very impressive.]
Records are made to be broken, but we think it will be quite a while before Paul’s 200-17X is surpassed in European competition. If you feel up to that challenge, consider competing in next year’s European Championships in late September 2017.

A few years back, we comparison tested four laser rangefinders — a Nikon, Leica, Swarovski, and Zeiss. To make a long story short, three out of four testers preferred the Zeiss PRF Victory. While larger and heavier than the Leica CRF 1600, the Zeiss Victory PRF was easier to hold steady, and it ranged as well as the Leica (and better than the Swaro and Nikon). Now the Zeiss Victory is on sale for $649.00, making it $150.00 cheaper than Leica’s CRF 1600. With this price advantage, we think the Zeiss is the smart choice (unless you need an ultra-compact unit). A recent LRF comparison test in the UK reached the same conclusion.

Weatherby’s new TacMark Rifles should be popular with long-range shooters (at least those with plenty of coin). We hope you like recoil — all three chamberings are powerful: .30-378 Wby. Magnum, .338 Lapua Magnum, and .338-378 Wby. Magnum. To handle these powerful cartridge types, TacMark series rifles have a beefy receiver with integral recoil lug, set in a CNC-machined aluminum bedding system. The bolt is interesting — it has nine (9) lugs and a 54-degree bolt throw.
The composite stocks are adjustable for length of pull (13¼ inches to 14¾ inches), drop at comb, and drop at heel. The stock also has a near-vertical pistol grip with a trigger finger depression and a wide, flat-bottom fore-end with a stud for bipod and/or sling. The TacMark (11.25 lbs w/o scope) comes in black while the TacMark Elite (11.75 lbs w/o scope) is finished in High Desert Camo with black accents.
The $5000.00 TacMark Elite features a hand-lapped 28″ Krieger cut-rifled barrel*, fitted with a large muzzle brake. The Range Certified (RC) TacMark Elite is accompanied by an Oehler Ballistic Imaging System printout signed and certified by Ed or Adam Weatherby, verifying the accuracy. The Elite is guaranteed to shoot sub-MOA for three shots (and we suspect it can do a lot better than that).
The less expensive ($3600.00) TacMark also boasts a 28″ barrel — one of the longest barrels currently available on a factory rifle. This should be good for a little extra velocity. Both the TacMark and the TacMark Elite feature Weatherby’s Mark V action and Weatherby’s new LXX trigger, which is user-adjustable for pull weight down to 2.5 pounds. The Mark V TacMark and TacMark Elite rifles will be available through the Weatherby Custom Shop.
* A features list on the Weatherby website shows 26″ barrel length for the Elite. However the actual specifications show the barrel to be 28″ for both TacMark and TacMark Elite. You should verify barrel length before ordering.

Brux Barrels, based in Lodi, Wisconsin, has earned a reputation for producing great-shooting tubes. Brux-made barrels have won their fair share of matches, and set some notable records in the process. Last year, Rodney Wagner shot the smallest five-shot, 600-yard group (.0349″) in the history of rifle competition, using a Brux barrel chambered for the 6mm Dasher.
Folks often ask us why Brux barrels shoot so well. “What’s the secret?” they ask. We can only answer with what Brux explains on its own website: “To make a cut-rifled barrel you have to start off with the proper ingredients: the best steel available, skill, and experience. Since there are really only two main suppliers of barrel-quality steel, the skill and experience is what really makes a barrel maker stand out.” Here is how Brux’s co-owners, Norman Brux and Ken Liebetrau, explain all the procedures involved in making a Brux cut-rifled barrel:
Brux Barrel-Making Process, Start to Finish
We start out with either 4150 chrome-moly or 416R stainless steel double stress-relieved bar stock. The bar stock starts out at 1-9/32″ in diameter and 20-24 feet long so we cut it to length.
Step two is to rough-contour the outside of the barrel blank in a lathe.
Thirdly, the blank gets mounted into a Barnes gun drill. The cutter bit has holes through which oil or coolant is injected under pressure to allow the evacuation of chips formed during the cutting process. This is called “oil-through” or “coolant-through”. Without this, you wouldn’t want to even attempt drilling a hole 30” long and under ¼” in diameter. The combination of a 3600rpm and good flushing allows us to drill a beautifully straight and centered hole .005” under “land” diameter at a rate of 1” per minute.
Clean the barrel.
Next the blank is sent back to the lathe to machine the finished contour of the outside.
Clean the barrel again.
Now, the blank is sent on to the Pratt & Whitney reamer in which an “oil through” reaming tool is used to cut away the extra .005” left in the drilling process. The reamer makes an extremely accurate bore size and after it is finished the bore will have a better surface finish and will be at the proper “land” diameter.
Clean the barrel again.
In the sixth step we hand lap each barrel to remove any slight tool marks that may have been left by the reamer and inspect every one with a bore scope. If the barrel doesn’t meet our standards for surface finish and tolerance it doesn’t get any further.
Clean the barrel again.
The barrels then go onto the rifling machine which is responsible for cutting the all so familiar grooves in the bore. A caliber/land configuration-specific rifling head is used to progressively shave away small amounts of steel to form the rifling grooves. This is accomplished by simultaneously pulling the rifling head through the reamed blank as the blank is spun at a controlled rate. After each cut, the blank is rotated 90 degrees (for a four-land configuration) and after one full rotation (360 degrees) the rifling head is slightly raised to shave off the next bit of material. This process is repeated until we reach groove diameter.
Clean the barrel again.
Lastly, the barrel is hand-lapped again (to ensure a smooth bore), and a final inspection is performed with the bore scope.
The barrel is cleaned one last time, wrapped, packed, and shipped to [the customer].
Anyone reading this detailed description of the Brux barrel-making process will doubtless come away with a new appreciation for the time, effort, and dedication required to produce a premium match-grade cut-rifled barrel. Obviously, there are no easy shortcuts and great attention to detail is required each step of the way. As shooters we’re lucky that we have barrel-makers so dedicated to their craft.

On German Salazar’s Rifleman’s Journal website, you’ll find an excellent 5-Part Series on barrel chambering. The Series, entitled The Voyeur’s Guide to Barrel Chambering, is not intended to be a “how-to” instructional treatise for gunsmiths. Instead, German’s 5-Part Guide is aimed at the end user — the shooter. German explains: “This Series isn’t intended for anyone who owns a lathe; instead it is for those of us who send an action off to get a new barrel installed. Those who have the equipment know what to do and how to do it and I have nothing to teach them. On the other hand, if you’ve ever wondered just what goes into barrel fitting, this is it.” PART I | PART II | PART III | PART IV | PART V
With well-written text and dozens of very high-quality images, German takes you through the chambering, threading, shoulder-fitting, and crowning processes from start to finish. The idea is to give the “barrel consumer” a clear idea of the processes involved when a barrel blank is converted into functional form, complete with chamber, threaded tenon, fitted breech, and crown.
We highly recommend German’s 5-Part Voyeur’s Guide to Barrel Chambering. German, with the aid of John Lowther (who ran the machines), did a great job. The series has already drawn much attention from our Forum members, along with praise. After reading the articles, John C. from Australia wrote: “Your Chambering articles… really are excellent [and] informative for those of us too scared to watch our gunsmith chamber one of our barrels lest we distract him at a crucial moment!”
We know you’ll learn something from reading through German’s 5-Part Series. And if you see a photo on German’s website that intrigues you, simply click on it to see a larger, higher-resolution version. All the images in the Voyeur Series on RiflemansJournal.com can be zoomed to larger formats.

Sometimes you’ll get a barrel that doesn’t stabilize bullets the way you’d anticipate, based on the stated (or presumed) twist rate. A barrel might have 1:10″ stamped on the side but it is, in truth, a 1:10.5″ twist or even a 1:9.5″. Cut-rifled barrels, such as Kriegers and Bartleins, normally hold very true to the specified twist rate. With buttoned barrels, due to the nature of the rifling process, there’s a greater chance of a small variation in twist rate. And yes, factory barrels can be slightly out of spec as well.
