For today’s Sunday GunDay story we showcase seven interesting metal-chassis rifles. While we love the look and feel of wood and fiberglass, metal does have its advantages. It can be crafted very straight and true, and the designs can achieve a very low center-of-gravity without sacrificing rigidity. In addition, a precisioned machined metal chassis tends to track extremely well.
Massive IBS Heavy Gun Milled from Solid Aluminum Billet
This remarkable 70-lb IBS Heavy Gun, was machined from solid aluminum billet, by Bruce Baer. It rests on a G&G Alvey rest split in the middle to comply with rules. This “heavy metal” CNC-machined wonder is a work of art designed for the 1000-yard game in the Heavy Gun class. Wood stocks, and to a lesser extent fiberglass stocks, are more forgiving, offering greater damping and recoil absorption. However, metal stocks offer superior rigidity, and the CNC machining allows tracking surfaces to be perfectly parallel.
Williamsport limits Heavy Guns to 100 pounds. Under IBS and NBRSA rules weight is unlimited. You will see a few massive 200-lb behemoths at IBS matches, but most competitors find that something in the 60-90 pound range works best. Bruce Baer explains, “You can’t stop a gun from recoiling. If it doesn’t recoil it will jump. If it jumps you might as well go home because you won’t shoot a good group. So it is pointless to try to build a gun so heavy as to eliminate all recoil. The more you restrict the rifle’s recoil the more temperamental that rifle will be. The 200-pounders just don’t out-perform something in the 60- to 80-pound range, and I think the optimal weight is 60-70 pounds.”
Bruce Baer likes the 70-lb overall weight for a heavy gun: “Extreme mass is not necessarily an advantage. Watch a locomotive starting up from zero–it will vibrate from one end to another. If the gun is too heavy I think it will vibrate at the start of recoil and that will kill accuracy. I want the gun to start from recoil with very little effort so it will be smooth from start to stop.”
Water-Cooled World Record-Setting Wondergun
We like “outside of the box” thinking. And in the world of competitive shooting, it can’t get more unconventional than this. But this radical liquid-cooled benchrest rig wasn’t just a crazy experiment — it actually delivered the goods. This IBS Heavy Gun, built by Joel Pendergraft, produced a superb 10-shot, 3.044″ group that stood as an International Benchrest Shooters (IBS) 1000-Yard Heavy Gun record for seven years, not being broken until 2016.
Using this water-cooled wondergun, Joel shot the record-breaking group in April 2009 at Hawks Ridge, NC. This monster features a .30-Caliber 12-twist, 4-groove Krieger barrel inside a water-filled sleeve (like on a liquid-cooled machine gun). Joel shot BIB 187gr flat-based bullets in Norma brass, pushed by a “generous amount” of Alliant Reloder 25 and Federal 210M primers. The cartridge was a big custom wildcat Joel listed as “.300 Ackley Improved”.
Pendergraft’s 3.044″ 10-shot group was a great feat, breaking one of the longest-standing, 1000-yard IBS World Records. And Joel’s 3.044″ record stood for 7 years!
F1 F-Open Chassis from Competition Machine
Along with his famed tube-guns, Gary Eliseo of Competition Machine has designed a modern, low-profile chassis system for F-Open competition. Assembled with Cerakoted aluminum beams, these F1 F-Open chassis systems offer great tracking with an ultra-low center of gravity.
Here is the F1 Chassis with “Marine Corps Red” powder coat finish. Read Full Report.
This F1 aluminum alloy chassis stock features a super-low center of gravity, plus adjustable length of pull, cheek rest, and drop. The stock is available in a wide choice of Cerakote finishes. The current Model F1 chassis features a action block mounting system to fit most actions. There was also an earlier version that had a free-floated action with the barrel in a barrel block, secured with epoxy. Both F1 versions (action block and barrel block) shot great, with excellent performances in competition.

State Championship Win with Home-Built Aluminum Stock
While most of the stocks featured above were crafted by professionals, the properties of aluminum allow it to be used by persons with some basic mechanical skills and metal-working tools. Here’s proof. Back in 2009, Forum Member John Dunbar (aka JD12) crafted his own aluminum F-Open stock. And he used that impressive metal stock to win the Wisconsin State F-Class championship. READ Full Story.
The stock for John’s “home-built” .284 Winchester was mated with a Savage target action. John designed and fabricated the aluminum stock himself. It features a central barrel block clamping a 32″ Brux barrel. Get this — John completed the rifle only 5 days before the match: “I finished machining/assembly on Monday night, did load workup Wednesday and Thursday nights, loaded rounds Friday night, and headed to Lodi at 4:30 on Saturday morning.” John even made his own co-axial front rest (see below)
Richard King’s Radical .223 Rem F-TR Skeleton Rifle
Here’s something exotic from our Gun of the Week archives. We like this rig because it is so radical (we doubt that you have ever seen anything quite like it). Gun-builder Richard King calls this his “Texas-T”, noting that “this is my personal gun, built the way I wanted it. I know it’s radical and some may not care for it. But it works.” The rig was designed to shoot F-TR, but it can also be converted easily to shoot F-Open with a front rest.
Richard reports: “This is pretty much an all-aluminum rifle. The action is a Kelbly F-Class with a Shilen stainless steel competition trigger. The scope is a 1″-tube Leupold 36X with a Tucker Conversion set in Jewell spherical bearing rings. The .223 barrel is 30″ Pac-Nor 3-groove, 1:6.5″-twist mounted in a V-type barrel block. The bipod has vertical adjustment only via a dovetail slide activated by a stick handle. It works like a joy-stick, but for vertical only. I adjust for windage by moving the rear sandbag.”
Richard likes how the barrel block works: “With the barrel block forward, the vibrations should be at a low frequency. Instead of one long rod whipping, I now have two short rods (barrel halves) being dampened. This is my fourth barrel block gun. They work, but so does a good pillar-bedded action. [This rifle] is designed for my style of shooting. It is not meant to be a universal ‘fit all’ for the general public. However, I will say the design is adaptable. I can easily convert the system to run in F-Open Class. I would drop a big-bore barreled action into the V-block, slide on a heavier pre-zeroed scope and rings, add plates on the sides up front to bring the width to 3″, and maybe a recoil pad.”
When Fiberglass Fails, Aluminum Stock Saves the Day
Australian Mark Fairbairn performed a “Quick Fix” during the 2018 Berger SW Nationals. Mark’s F-Open rifle, in a conventional fiberglass stock, was giving him random vertical during one yardage: “I had a bit of a problem with elevation — the stock was hitting somewhere [causing vertical]. I was X-X-X then a shot popped up in the 9 ring with no good reason. So I figured I better put a new stock on it. I got my old aluminium stock I brought from Australia and quickly adjusted it to fit on the Stolle.”
Right on the firing line berm Mark swapped his barreled action into the metal stock of his own design. The clock was ticking… but the story had a happy ending. For the next yardage Mark shot a brilliant 150-7X, not dropping a point. So the “Quick Fix” did the trick. As they say Down Under — “Good on Ya, Mate!”
Home-Built Aluminum Chassis with Innovative A-Arm Bipod
Here is another home-built rig featuring an aluminum chassis mated to a Savage barreled action via a forward-mounted barrel block. This rig was crafted by Forum member Patrick Lundy, who followed the maxim: “If you can’t buy it, then build it.”
Patrick Lundy was so impressed with a fellow shooter’s barrel-block rifle, that he build a similar match gun himself, complete with barrel block and aluminum chassis. Patrick was inspired by a metal stock belonging to Peter Gagne. But he added his own custom touches, including an innovative “A-Arm”-design bipod for shooting in F-TR class. The gun has been very successful in competition. READ FULL Report
Pat told us: “This new stock was a milestone in my shooting career — it was my very first attempt to build a stock. I wasn’t much of a wood worker but I did have a talent for building with metal. The stock was fabricated from 6061 T6 aluminum. With this gun I was able to shoot from a rest or a bipod.”
Pat crafted the bipod from aluminum tubing: “The bipod was a very rigid A-frame design with welded aluminum tubing. I added slippery feet under the pod skis to facilitate smoother recoil. I realized that a wide-stance bipod had to recoil the same on both sides or the group would string horizontally.” Here is the innovative “A-Arm” bipod that Pat Lundy built for his rifle.
Ever wish you could look inside your rifle, to see how the trigger and fire-control system work? Well now that is possible with the magic of 3D computer graphics. Modern software allows detailed “cutaway” side-views (see below), as well as 3D views with 360° rotation. The software can also provide X-Ray-type views into the gun’s internals — as you can see above. And computer animation can show the complete firing process from trigger pull to chambering of the next round.
Rem 700 Cutaway View from Right Side
This article provides some very cool 3-D “Cutaway View” animations of the popular Remington 700 action, probably the most successful American bolt-action ever created.
READERS — Take the time to watch the video! The Rem 700 animation is really outstanding! EVERY bolt-action shooter should watch this video all the way through.
Cutaway 3D Animation of Rem 700 Action — Watch Video
The Model 700 series of bolt-action rifles have been manufactured by Remington Arms since 1962. All are based on basically the same centerfire bolt action. They are typically sold with an internal magazine depending on caliber, some of which have a floor-plate for quick-unloading, and some of which are “blind” (no floor-plate). The rifle can also be ordered with a detachable box magazine. The Model 700 is a development of the Remington 721 and 722 series of rifles, which were introduced in 1948.
The Remington 700 is a manually-operated bolt action with forward, dual opposed lugs. It features “Cock On Opening”, meaning the upward rotation of the bolt when the rifle is opened cocks the firing pin. A cam mechanism pushes the firing pin’s cocking piece backward. The bolt face is recessed, fully enclosing the base of the cartridge. The extractor is a C-clip sitting within the bolt face. The ejector is a plunger on the bolt face actuated by a coil spring. The bolt is of 3-piece construction, brazed together (head, body. and bolt handle). The receiver is milled from round cross-section steel.

If you are looking to acquire a reliable, accurate rifle for a late fall hunt, Howa can be a good choice. Howas feature smooth-running actions with fine two-stage HACT triggers. A Howa barreled action can also be a good basis for a DIY project. But some folks have heard that it may be difficult to find stocks, or to fit an after-market barrel. That’s not true. There are many stock options available, and in this article, Bill of RifleShooter.com shows that it is easy to remove the factory-installed barrel with the right tools. We think a Howa makes a fine basis for a varmint rig or field rifle. Or you can build a tactical rifle as Bill did. You can start with the factory barrel and when you want/need more accuracy, then have a gunsmith install a custom barrel from Krieger Barrels, Lilja Barrels or other quality brand.
The Carbon Stalker is an excellent ultralight factory option, weighing just 4.6 lbs. with Mini Action (before optics). All Howa Carbon Fiber Stalker rifles come with a Sub-MOA Guarantee and Lifetime Warranty.
What You Need to Know About Howa 1500-series Rifles
Tech Feature by Bill, editor of RifleShooter.com
Consider this article the “Howa 1500 Overview”. There has been a lot of interest in Howa rifles and barreled actions imported by Legacy Sports International. In addition to being able to buy a complete rifle from a dealer, Brownells sells barreled actions in a wide variety of calibers and configurations. In this post we are going to take a look at the Howa 1500 series.
Howa Rifles — General Background
Howa is a Japanese heavy machinery company. One of its product lines are firearms, which are imported into the United States of America by two different companies, Legacy Sports International and Weatherby. Legacy sells the 1500 under the manufacturers name while Weatherby re-brands the guns as the Weatherby Vanguard. In general, the finishes on the Weatherby rifles are more refined than the LSI-imported 1500s.
General Evaluation of Howa 1500 Rifles
I’ve found Howa 1500s to be solid, entry-level rifles that are capable of sub-MOA accuracy out of the box. I’ve actually purchased two Howa rifles I’ve tested because I like them so much. The gun below, a Howa Mini-Action in 7.62×39 Russian, is one of my favorite factory guns to shoot.
Check out this three-shot group I drilled at 100 yards with the rifle above and 125-grain Sierras. It took a lot of work and load development to get there, but when it did, it worked well.
Howa 1500 HACT 2-Stage Trigger
Howa 1500s feature the very nice Howa HACT trigger. This is an adjustable, two-stage trigger, set for about 3 pounds (combined stages). Crisp and repeatable, this is an excellent trigger for a factory gun. There is no annoying Glock-style safety lever in the middle of the trigger blade. The 2-stage design and pull weight range works well for a hunting rifle or a rig for PRS competition. Rifleshooter.com says the Howa trigger is “one of the best factory triggers, along with Tikka. I’ve found the Howa trigger superior to a Remington 700 — the Howas doesn’t need to be replaced.”
Writing for the Western Outdoor News, WONews.com, Steve Comus has field-tested the HACT Trigger. Steve writes: “I always liked two-stage triggers, because of the way I could take-up the slack and then actually know when the rifle was going to go off. The take-up on the [HACT] trigger was fast and easy. The crisp, positive release when pressure was put on during the second stage [reminded me] of some of the target rifles I shot through the years.”
Howa Actions — Three Options
Howa offers three action lengths: Mini, Short, and Long. You can see the bolts for the three action lengths in the image below. The Mini-Action has similar external dimensions to the Remington Model Seven, however, the Mini-Action’s bolt does not travel as far to the rear. This is a mixed bag. The upside is you have a quicker action (shorter bolt throw). The downside is you are limited to shorter rounds such as the .223 Remington, 7.62×39mm Russian, and 6.5 Grendel. But if you need a bigger cartridge, just choose the standard or long action Howa variant.
Howa 1500 vs. Remington 700 — Important Differences
Is the Howa 1500 a Remington 700 clone, or some kind of improved Remington 700? No, not really. While the top radius of the Howa 1500 does match the Model 700, and they can both use the same two-piece scope bases, there are a number of differences.
If you look at the Howa 1500 alongside the Remington 700 you’ll note the M700 is a round action, while the Howa is a flat-bottom action. In many ways the Howa’s bottom half reminds me of a push-feed Winchester. This means the chassis and stocks that support a Howa 1500 are not V-block based like you’ll find on a 700, instead they have a flat bottom. While the bolt of the Howa is similar in external appearance to the Model 700, it does offer some improvements, notably an M16-style extractor and a firing pin assembly that can be easily removed without tools.
Howa 1500 action screws are metric and are in a different location from the 700. The Howa 1500 has an integral recoil lug that accepts the front action screw, this means you have more of the front action screw engaging the action. WARNING: If you install it into a poorly-fitted stock or action you may bind it.
Can a Howa Action Be Used for a Custom Rifle Project?
Absolutely! You can either buy a barreled action from Brownells and throw it in a chassis system/stock of your choice or you can use a stripped action to build a custom rifle. If you are in the chassis market, MDT offers a wide variety of chassis in different price ranges. All have worked well for me.
How to Remove Howa Factory Barrel from Action
You may have heard internet grumblings about removing Howa barrels. Some keyboard commandos say they are extremely difficult to remove without a relief cut. Well Bill at Rifleshooter.com demonstrates that Howa barrels can be removed without trouble, provided you have the right tools. Watch this video:

Q: Is it difficult to remove a barrel from a Howa 1500?
A: Not very. I’ve heard from some smiths that worked on Howas (years ago) that the factory barrels are difficult to remove. However of the half dozen or so Howa barrels that I’ve pulled, they’ve been very easy. I use a Brownells action wrench with the top piece for a Rem Model 700 and the flat bottom resting against the flat on the wrench.
Howa Actions Require Metric Barrel Threads
It’s easy to thread a barrel for a Howa action. You just have to cut metric threads — most lathes out there can cut them. I cut the threads below on a manual lathe using change gears. [Editor: John Whidden cuts metric tenon threads with a CNC lathe. “It’s easy,” John tells us, “No issue whatsoever.”]
Using Howa Actions for Custom Rifles
I have built a few customs with Howa actions. Below is one of my favorite, a .308 Winchester. It consists of a Howa 1500 action, Shilen Select Match Rem Varmint contour barrel\, and Modular Driven Technologies (MDT) ESS chassis. Great rifle and it hammers!

Historic American Arms — Teddy Roosevelt’s Lever Guns
These two lever action rifles, owned by President Theodore Roosevelt, are part of the NRA Museum collection. First is a Winchester 1886 rifle known as the tennis match gun because Roosevelt used winnings from a tennis match to buy it. Below that is a suppressed Winchester model 1894 rifle. Roosevelt liked to shoot varmints around Oyster Bay (Long Island, NY) with this gun so he wouldn’t disturb his neighbors — the Tiffany and Du Pont families.
About the NRA Museums
The NRA opened the original National Firearms Museum at its Washington DC Headquarters in 1935. In 2008 the Francis Brownell Museum of the South West opened at the NRA’s Whittington Center in Raton, NM.

Forum member Rardoin’s handsome F-Open rig features the Borden BRM-XD action.
One of the most popular items in our Shooters’ Forum is the ongoing “Pride and Joy” thread. Since 2009, Forum members have posted photos and descriptions of their most prized rifles. Here are some of the most recent “Pride and Joy” rifles showcased in our Forum. Do you have a gun you’d like to see featured there? Just Register for the Forum and you can add your favorite gun to the list.
Modern 6BRA Bench Rifle
This handsome benchrest rig belongs to Forum member Tillroot1. It boasts a Kelbly Panda action and a Krieger cut-rifled barrel chambered for the excellent 6BRA wildcat cartridge. The 6BRA is an improved version of the 6mmBR which retains the long neck. The 6BRA is easy to fire-form and very accurate, and can achieve the really good 2950 FPS node with 105-108gr bullets. This cool rig features a Jason Avila-made stock (Wheeler F-Open), with finish work by Brett Childress. Barrel was chambered by Dave Witt.
Bill Goad’s 6PPC Hunter “Ranch Rifle”
Forum member Grimstod tells us: “This is the personal rifle of Bill Goad. He has been experimenting with it on several levels. It is shooting great and has several matches on it now. Please enjoy these photos. More can be found on the website www.PremierAccuracy.com. We like the subtle barbed wire effect on the stock.
Twin-Upper AR with Custom Wood Furniture
This very unique AR belongs to Forum member Nuto-BR. He tells us: “Here are the two uppers I built. The top one is am X-caliber in 20 Practical with 24-inch, 1:11″-twist barrel. The bottom one is a WOA in .223 Rem, with 20″, 1-12″ twist barrel. They both shoot 1/2 MOA or better. Both stocks are laminated Maple and Walnut. I reversed the order of the two woods to tell them apart.”
Two Dashers and a Rimfire for Fun
Courtesy Forum member Dan H., here are two red-stocked Dashers plus an Anschutz 54.30 (Benchrest Stock) to make it a trio. Dan says: “The Anschutz provides good practice in trigger-pulling. It’s amazing what you can learn from a rifle that is as sensitive as this one.”
Dream Hunting Rifle with Custom Camo
Here is Forum member TyDaws’s “Dream Hunting Rifle” in 6.5-280 Ackley Improved. We love the custom paint work by by Melodie Yarbrough. Smithed by West Texas Ordnance, this rifle features a Rem 700 action with fluted bolt, PT&G tapered recoil lug, and Timney 510 2-lb trigger. The barrel is a fluted 26″ 1:8″-twist Bartlein 5R #3 contour. On top is a Huskemaw Blue Diamond 4-16x42mm optic in Warne Maxima rings. That’s an Atlas bipod up front.
Three Guns for Mr. Big
Forum Member Mr. Big offered up another trio of rifles — two bench guns and a tactical rig. Mr. Big says: “Here are the rifles I shoot most: Farley 6mm PPC, Stiller .243 Win, and Rem 6.5×47 Lapua. They will do just about anything I ask them to…” Challenge: Can you identify the makers of the three different stocks shown in this picture (and the different materials used in each)?
Classic M1917 Enfield Action in Hand-Carved Maple Stock
This impressive rifle features an “antique” 1917 Enfield action chambered for the .338 Win Magnum cartridge. The lovely Maple stock was hand-carved by Forum member Spitfire_ER. He tells us: “I found this piece of wood as a return at a lumber yard about [many] years ago. I asked the guy in the yard about it and he said it had been returned because it had too much figure for the job the customer was working on. First thing I thought was, ‘That would make a nice stock’.”
6mm Dasher in Robertson Spider Web Stock
Here is Forum member Vahena’s 6mm Dasher. It has a no-turn-neck chamber in a 28″, 1:8″-twist barrel with 1.25″ straight contour. This has an original Robertson fiberglass stock with spider web graphics. This rifle was originally built as a 6.5×284 with a fluted barrel. Now it sports a bigger barrel for a smaller cartridge. The front rest is a SEB Neo with counterweight up front.
Can sustained rapid-fire shooting with no cool-down period wear out a quality barrel more quickly? The answer is “Yes” according to Forum member LCazador, who did an interesting comparison test with two .243 Winchester barrels. He started off with two, identical, match-grade HV taper stainless barrels. Both were NEW at the start of testing, and LCazador shot the same load through each: 95gr match bullets with 38 grains of Hodgdon Varget. After giving both barrels the same, gentle 20-round break-in, 300 rounds were then fired through each barrel — in very different ways. Barrel condition and wear were monitored with a borescope.
Barrel One — Slow Fire, Cool Down Periods, Cleaning Every 50 Rounds
At the end of the 300-round test, Barrel One looked brand new. There was none of the severe fire cracking found in Barrel Two. This barrel was shot no more than 10 times without a cool down and firing was done at a much slower pace. Cleaning for this barrel was done every 50 shots.
Barrel Two — Fast Firing, No Waiting, Cleaning Every 100 Rounds
The second barrel, which received hard use and minimal cleaning, was severely damaged with severe fire cracking at the leade and throat. As a result, the barrel had to be re-chambered. This barrel was shot 100 rounds at time without cleaning and was shot up to 20 times in succession without a cool down.
LESSON LEARNED — Heat Kills Barrel Life
Don’t let your barrel get too hot, and keep it clean. One afternoon can ruin a barrel!
Monitoring Barrel Wear with Borescope
Some folks worry too much about what their borescopes reveal — many barrels do not have to be “squeaky clean” to perform well. In fact some barrels run better after ten or more fouling shots. However, a borescope can be very helpful when your barrel starts losing accuracy for no apparent reason. Forum member FdShuster writes:
“A borescope is a positive way of backing up your suspicions when the rifle starts to throw an occasional (soon followed by more frequent) wild shot. Using the scope is also an excellent way to determine that the cause is barrel wear and not simply a need for a concentrated cleaning session to remove built up copper and more importantly, carbon fouling.
I’ve had a few barrels that gave every indication of being shot out. But I ‘scoped them out and found the cause to be nothing more than requiring a good cleaning. They then returned to their usual performance. There’s no guessing involved when you are able to get ‘up close and personal’ using the scope. The borescope also provides an excellent view of the all-important condition of the crown. My borescope is one of the most valuable investments I’ve ever made.”
Editor’s Note: This story was first published many seasons ago. In the interceding years, equipment has evolved — actions, optics, front rests and so on. But this rifle remains very competitive in the 600-yard silhouette game, and it remains a wicked weapon for long-range varminting.
The 6-284 may well be the “ultimate” 6mm cartridge, if speed AND accuracy are considered. While it burns a lot more powder than a 6mmBR or 6 Dasher, it also delivers a lot more velocity. Our friend John Southwick, owner of this week’s featured 6-284, can push 107gr SMKs past 3400 fps — velocities no 6BR, 6BRA, or 6 Dasher can touch. He normally dials that back to 3200 fps or so, but that’s still well beyond the limit of a 6 Dasher even a 6mm Creedmoor. John’s gun is more than a speed demon of course — it’s a hyper-accurate match rifle that has claimed many Varmint Silhouette wins. At his club, when John and the Black Borden come out to play, everyone else is usually competing for second place.
Building the Borden Black Beauty
John tells us: “I chose the 6-284 mainly because it appeared in the winning equipment lists of 1K BR matches, and it was becoming very popular with long-range varminters. Skip Talbot had also used a 6-284 to set an IBS 1000-yard record (subsequently lowered in the last decade). Norma and Lapua offered quality 6.5-284 brass, so case-forming would be easy. I wanted a fairly light-recoiling rifle, and after much research I came to the conclusion that a high-BC 6mm bullet driven at 3200+ fps would meet my needs.
I was looking for a very high performance long-range target/bench rifle, primarily to use in 600-yard matches at my local club (Ojai Valley Gun Club), and possibly 1000-yard bench matches, plus occasional varmint hunting. I wanted to have a rifle that was built by a prominent gunsmith. I chose to work with Jim Borden of Borden Rifles for several reasons: his rifles had set world records, his reputation was excellent, and his rifles often showed up in the winning equipment lists of IBS and NBRSA sanctioned shoots. Also I had decided that I wanted a Nesika-actioned gun. I was impressed that Jim had designed one of the Nesika’s key features – Borden Bumps. Likewise, I liked the Bald Eagle front rest, and found out that Jim contributed to its design as well. This gave me confidence that Jim understood every element that goes into precision rifle performance.
Loading for Accuracy
My match load consists of Norma 6.5-284 brass, 51.0 grains of Alliant Reloder 22, Fed 210m primers, and Sierra moly-coated 107gr MKs, seated about .010″ into the lands. This runs about 3250 fps from the 28″ barrel. Case necks are turned to .0133″ wall thickness for a .270″ loaded neck diameter. I use a .268 or .269 bushing, and bump the shoulders back each time. I set the “bump” so that, with firing pin removed, I can just feel the case in the chamber when closing the bolt. My loaded rounds typically show no more than .0015″ runout on a NECO concentricity gauge. I credit the low run-out in large part to the custom inline seating die and shoulder-bump neck-bushing die Jim made for me.
How the 6-284 Shoots
The rifle has fulfilled all my expectations. It is a superbly precise and accurate rifle, as long as I do my part in steering the gun and feeding it consistent, quality ammo. I haven’t done a lot of 100-yard group shooting, just enough to test loads. Typically the rifle easily puts five shots into half-MOA or less at 600 yards. I’ve logged several 3-shot groups between 1.06″ and 2.2″ at 600 yards. I’ve been told that kind of accuracy would be competitive in a 600-yard BR match. But most importantly, I have confidence the gun will hit where I aim. Our Ojai club uses half-size silhouette targets. This gun’s ability to pick off the relatively small steel targets, even in some of the worst conditions imaginable, is nothing short of amazing. At times it seems I’m launching 107gr silhouette-seeking guided missiles.”

A Special Brand of Silhouette Shooting
John’s rifle is a purpose-built gun, optimized for one task — hitting little half-size silhouettes at very long distances, at a shooting venue that demands serious wind wizardry. At Ojai, even though matches commence early in the morning, it’s not unusual to have a 10 mph wind blowing left to right at the firing line, no wind at the mid-course flag, and a swirling variable wind at the targets. To make matters worse, the little critters sit on top a ramped berm. When the wind switches to 6 o’clock, it can rise right in front of the target, sending shots high. Despite the often-wicked conditions, John and his Black Borden have excelled at the varmint matches — he’s the “smart-money” bet to win on any given weekend.
John reports: “The rifle has really proven itself at the 600-yard silhouette match at my local club. We shoot ten targets per match, usually three “matches” or relays per day. Targets are half-size NRA Hunter Pistol metallic silhouettes: 1 Ram, 2 Turkeys, 3 Pigs, and 4 Chickens (note, these are larger than the mini-silhouettes in the above photo). The Ram counts one point, Turkey two points, Pig three points and the Chicken counts four points. The Chickens have a “hit zone” roughly .6 MOA at 600 yards–about 3.6″. Trust me, that can be challenging, particularly in shifting winds. Unlike conventional silhouette matches, we shoot F-class fashion from the ground, using bipods or pedestal rests. That’s easier than shooting off your hind legs of course, but our targets are much smaller than standard high-power silhouettes.”
The Black Borden was the rifle to beat at Ojai for many years. John held the record for the most “cleans” (no misses) for the event, and he was the annual Champion for many years, including five years in a row. One year he won the championship in the very last match. John noted: “Thankfully, the gun was humming and I made the right wind calls. I picked up enough points in the final shoot to win the series for the year.” Yes, John’s flat-shooting Borden 6-284 had done its job once again.
Long-Range Silhouette Match Strategy and Techniques
In competition, John says watching the conditions, and minimizing mental mistakes is key: “I keep things pretty basic. Our varmint silhouette matches allow 20 minutes for sighters and 10 shots on target (one per animal). We usually get in three “matches” or relays per event. I try to wait for a favorable condition, then take a few sighters and adjust the scope as needed. If the condition holds steady, I’ll try to run my targets before the wind changes.
At the Ojai range, it is vital to watch the wind flags and heed your spotters’ calls. I’ve seen the wind go from 7mph right to 10mph left from one target to the next. That’s nearly a foot and a half of horizontal change for my gun. If there is a major change, I will try to wait it out. If the shift is small, I may hold off a bit. Scope corrections are a last resort; while you’re dialing, the wind may switch again.”
Technical Report from Jim Borden, Gunsmith
We set up John’s 6-284 as we would for 1000-yard Light Gun competition. We’ve also built some of these rifles in 6MM BR for use in 600-yard competition. For John, we used a Borden/Nesika Model K 1.70″ diameter action as the beginning basis of the rifle. The timing and cocking-piece system for this rifle has the Borden improvements to improve firing pin energy and lock time. The action was pillar-bedded and glued into a McMillan Tooley MBR pattern stock. The stock blank was gel-coated and then epoxy-finished with a texture.
About the Muzzle Brake — We normally blend the brakes into the barrel to make the transition smooth and unseen. John preferred to have the brake larger than the barrel so that it could also be used on future barrels.
9-Twist Barrel — The barrel is a 1:9″-twist Hart HV pattern 28 7/8 inches long. Our 6×284 reamer has a .272″ neck diameter. It is throated with a tight cylindrical section followed by the 1 ½ degree throat. Chambering of the barrel was done utilizing our proven Benchrest chambering techniques. The method of chambering ensures that the body, neck and throat of the chamber align concentrically with the bore and grooves of the barrel. [Editor: With a 6BR or 6 Dasher, we’d definitely recommend an 8-twist barrel to shoot 105-107 grain match bullets. However, with the extra velocity of the 6-284, the 9-twist Hart worked great for John.]
NOTE: Borden Accuracy (BordenRifles.com) now produces its own excellent Borden Custom Actions, which have won National Championships and set World Records. Borden offers precision bolt action receivers for competition, ELR, hunting, varmint, PRS, and other shooting applications.
Situated in the Coastal Mountains behind Ventura, California, the Ojai Valley Gun Club is a beautiful place to shoot. And the Hwy 33 route up to the range offers stunning views.

The last half-inch or so of your barrel is absolutely critical. Any damage (or abnormal wear) near the crown will cause a significant drop-off in accuracy. Here are ways you can check the end of your barrel, using a common Q-Tip.
Use Q-Tip for Barrel Inspection
To find out if you have a burr or damage to your crown, you can use an ordinary Q-tip cotton swab. Check the edges of the crown by pulling the Q-tip gently out past the edge of the crown. If you have a burr, it will “grab” the cotton and leave strands behind.
Larry Willis has another way to use a Q-Tip: “Here’s a neat trick that will surprise you with how well it works.” Just insert a Q-Tip into your barrel (like the picture below), and it will reflect enough light so that you can get a real good look at the last half inch of rifling and the crown of your barrel. In most cases you’ll find that this works much better than a flashlight. Larry tells us: “I’ve used this method about a jillion times. Q-Tips are handy to keep in your cleaning supplies anyway. This is a good way to judge approximately how well you are cleaning your barrel when you’re at the range. It’s also the best way to examine your barrel when you’re in the field.”
