Are you looking to shave POUNDS from your hunting rig or varmint rifle? There are now multiple options for folks looking for a weight-saving, carbon fiber-wrapped barrel. You’ve probably heard about Proof Research. Yes that’s a good company that crafts good products. But now Proof Research has some noteworthy competition — Helix 6 Precision in Washington State.
Helix 6 Precision crafts button-rifled and cut-rifled carbon-wrapped barrels in both conventional and “pre-fit” configurations. The conventional (not pre-fit) carbon-wrapped Helix 6 barrel blanks cost $979.99 for most listed chamberings. Pre-fits are offered for Savage rifles, Ruger Precision Rifle (RPR) series, Tikka T3, Aero SOLUS, Defiance Ruckus, Sig CROSS, and Zermatt rifles. These pre-fit barrels are not cheap. A 6mm Creedmoor RPR pre-fit costs $1099.99, while the Savage pre-fits are also $1099.99 for most chamberings.
While Helix 6 barrels do offer significant weight savings, the founders of Helix 6 say low mass wasn’t the number one design goal: “Accuracy was paramount and weight reduction was secondary. We’ve taken the industry’s most advanced carbon fiber engineering and pushed the technology further with our proprietary … carbon fiber process.”
The founders of Helix 6 Precision say they build some of the best carbon/steel hybrid barrels on the market: “Our unique carbon fiber-layup design dampens barrel harmonics for better accuracy. Each barrel is cut from a 416R stainless steel core, and carbon fiber-wrapped using the Helix 6 Precision’s advanced process. This creates match-grade accuracy barrels with high heat dispersion that are 30% lighter than a steel barrel of the same contour. The bores are … hand-lapped for precision accuracy.” Helix 6 claims its barrels are “lighter, stronger, and faster cooling than anything else available on the market.”
Myth vs. Reality — What Carbon Can and Cannot Do
Carbon fiber is formed using thin strands of carbon bonded together with a plastic polymer resin. The resulting material is very strong and light weight. There’s a reason Formula 1 cars are crafted with carbon-fiber composites. But is a carbon-wrapped barrel the right option for you? Here are some factors to consider:
Weight Savings — There’s no doubt that a carbon-wrapped barrel will weigh less than an unfluted stainless steel barrel with identical length and contour (outside diameters). Helix 6 claims a 30% weight reduction compared to a conventional stainless steel barrel. That’s significant.
Accuracy — Carbon-wrapped barrels are NOT commonly being used for F-Class or Benchrest competition. However, Proof Research carbon-wrapped barrels have performed well in PRS competitions in the hands of top shooters. So, we can conclude that carbon accuracy is good enough for the PRS/NRL tactical game, at least at the local club level.
Heat Dispersion — Carbon-wrapped barrel-makers claim their hybrid design disperses heat better than an all-steel barrel. Some independent testers disagree, saying: “hold on now — the carbon actually acts as an insulator, so more heat is retained in the barrel”. The jury is still out. One thing that is true is that the carbon barrels seem to generate less mirage from barrel heat. Ask yourself, “if less heat is coming OFF the barrel, where is that heat retained?” But the reduced mirage could be a function of the black woven surface which may release heat differently than polished steel.
Pre-Fit, AR, and Custom Barrel Options
Helix 6 precision barrels are available as pre-fits for a wide variety of rifle types in many popular long-range cartridges. Helix 6 can also thread and chamber a barrel for most precision rifles. And pre-fit AR barrels are available in a wide variety of chamberings and lengths. Helix 6 Precision also supplies carbon-wrapped barrel blanks which can be chambered and fitted by a professional gunsmith. Helix 6 barrel blanks, buttoned-rifled or cut-rifled, are sold in many calibers. Offered calibers are: .224, .243 (6mm), .264 (6.5mm), .257 (pending) .277 (pending), .284 (7mm), .308, .338, and .375. In addition, .22 LR rimfire carbon barrel blanks are offered.

Forum member Jacob spotted this simple, but effective set of scope ring inserts on the Brownells Website. With these inserts, you can use a scope with 1″-diameter main tube in 30mm rings. Non-marring, matte black Delrin sleeves surround the scope tube so it can fit larger-diameter rings. Each sleeve comes in two parts for easy installation around your scope tube. This way you can use the same 30mm rings for all your scopes.
Ring Reducers are sold as front/rear kits. Cost is $16.99 for the Delrin 30mm to 1″ converters, item 084-000-091WB. There are also sets that reduce 30mm rings to 26mm, and 1″ rings to 3/4″ or 7/8″.
Note: These Brownells units simply function as plastic bushings. Unlike Burris Signature Ring inserts, they do not allow you to “pre-load” windage or elevation. If your rings are misaligned, the Brownells Ring Reducers won’t correct that problem.
Every wondered how modern rifle actions are designed and crafted? Want to know the fine details of firing pin function and bolt lock-up? Then you should definitely watch this highly informative YouTube video. Top F-Class shooter Erik Cortina of Cortina Precision interviews Jim Borden, an engineer whose Borden Accuracy company produces some of the best rifle actions ever made. This is one of the better Erik Cortina video interviews. You’ll learn quite a bit from watching the video. The full video runs over two hours, so you may want to watch in segments over a couple of days.
Viewers have praised this interview, saying it has a wealth of information:
Gunsmith Alex Wheeler observed: “I consider Jim a friend even though we have never met. Definitely one of the guys that really gets actions. There’s not as many of them as you would think. He was the first timed action out there that had good ignition, at least in my opinion. It was a great interview. I do hope he has him on again.”
“Agreed. Jim is full of information and really does a good job on his actions. This [Cortina] interview with Jim Borden was excellent.” — Jud96
“I really like Jim’s explanations on why ductility is so important in an action. Especially in the critical areas that basically form 90 degree surfaces, such as where bolt lugs meet the bolt body. There is a lot of great info in this interview.” — Jackie Schmidt
“I have enjoyed all of Erik’s interview videos, which are very informative. But I agree [that] this interview with Jim Borden is the best. I learned a lot. Thank you Erik and Jim!” — Alexander-M

Making your own precision handloads is a meticulous journey with many steps, many important matters to consider, and many sets of measurements to calculate. For those who pursue the perfect group, the highest score, the really long accurate shot, the rewards more than outweigh the effort. Choosing the right cases, deburring the flash holes, making the primer pockets uniform, trimming the cases, and lubricating them are all familiar – and critical – steps along the journey. And now that your brass preparation is complete, you are at last ready to start running the cases through your press and fill them with primers, powder, and bullets. The very first die the brass encounters is the sizing die. You insert the case, work the press’s lever to return the case to its correct pre-fired dimensions – and the journey continues.
There are three types of sizing dies to think about: neck, full-length, and small base. All three have specific benefits and potential drawbacks, and you should choose the type of die you use by thinking very carefully about what kind of shooting you plan to do with your handloads. No matter which type you select, most sizing dies will also punch out the old spent primer with some sort of decapper assembly that uses a hardened steel rod. Many types of sizing dies use an expander ball inside the die to make sure the neck of the case will accommodate a bullet after being sized. With some size dies, the expanders are easily removable and interchangeable, letting you get exactly the neck tension you want. When sizing cases (neck of full-length), rifle cases always need lube.
Neck-Sizing Dies Neck-sizing dies resize only the neck of the case. The benefit of sizing only the neck is that the brass is “worked” very little, reducing the amount of changes to the brss. [We recommend full-length sizing for all applications after the first couple of firings, and semi-auto brass should be full-length sized every time!] Sinclair recommends that neck-sized-only cartridges should not be used any in other rifle besides the one they were originally fired from [unless they are also FL-sized], or in any action other than a bolt-action.
Full-Length Sizing Dies
Full-length sizing dies resize the full length of the case, not just the neck. Full-length sizing helps create handloads that will function in any rifle, not just the one from which the cases were originally fired. The potential downside of full-length sizing is that it may shorten case life because it works the brass more than neck sizing. But it’s possible to “tune” today’s full-length sizing dies so they barely work the brass at all, as this article by Sinclair Reloading Tech Ron Dague shows.
Illustration Shows How a Full-Length Sizing Die Works
Another way to reap the benefits of full-length sizing is to use Redding’s full-length bushing dies, which size the full length of the case but use a system of interchangeable bushings that enable you give the case neck the bare minimum of resizing needed. To see how finely adjustable bushing dies are, and how they resize the case while fully supported, CLICK HERE for Video. The neck bushing helps you precisely control the neck tension to help increase the consistency and accuracy of your handloads.
Small Base Dies
A Small Base Die is another type of full-length sizing die, but one that is typically used when reloading for semi-automatic rifles, like the AR-15, M14, or AR-style .308 rifles. (It may also work well for bolt guns that need extra sizing on the lower section of the case.) A small base die works exactly like a full-length sizing die, only it compresses the brass just a bit more, usually about .001″ more, and may even push the case shoulder back just a hair. Small base dies give that extra bit of compression to the brass to help make sure the case will properly extract from a semi-automatic firearm. The upside is that you get handloads that should work flawlessly in your semi-automatic. The downside is case life may be shortened as compared to brass used only in one bolt-action rifle, because the brass is worked more.
Shoulder Bump Gauges
A handy tool for setting up your full-length sizing dies as close as possible to your rifle’s chamber is a shoulder bump gauge. The bump gauge lets you resize the case as little as possible, to extend case life and help your handloads fit your rifle almost like a neck-sized only die. You use deprimed cases fired in your rifle and bump gauge inserts to help you set up the die so it resizes the case only about .001″ to .004″, depending on what type of rifle you’re shooting.

Sherri Jo Gallagher, the second woman in history to win the NRA High Power National Championship, sports Eye Protection at Camp Perry. The first lady High Power Champion was Sherri’s mother, Nancy Tompkins.
In response to a Bulletin article about Protective Eyewear, one of our Canadian readers posted a personal story. His account demonstrates the importance of wearing eye protection whenever you shoot — no matter what type of firearm you are using — even air rifles. We hope all our readers take this to heart. All too often at rifle matches we see shooters, even some top competitors, risking their vision by failing to wear eye protection.
Eye and Hearing Protection are now MANDATORY for Highpower Rifle competitors and Pistol shooters in all CMP-affiliated matches. The 2020 CMP Highpower Rifle, Pistol, and CMP Games Rulebooks all contain the following rule: “All competitors and competition officials are required to wear appropriate eye and hearing protection when on shooting range firing lines during highpower rifle or pistol firing. All competitors must comply with this requirement before they can participate in a CMP sponsored or sanctioned competition. Competitors are responsible for selecting their eyewear and hearing protection.”
Eye Protection — Lesson Learned by Nicholas from Canada
As a boy on a mixed farm on the plains the first shooting stick I owned was a Red Ryder BB gun. My Dad bought it for me as I showed a keen interest in the shooting and hunting sports. I was about 9 years old at the time.
We had literally thousands of sparrows in our large farm yard and they liked to roost on the steel railings in the barn loft. I took to slowly thinning out their ranks by flashlight at night as these little winged pests settled in the farm buildings.
One evening as I slayed sparrow after sparrow in the barn loft — with about a dozen farm cats following me to consume these easy meals, I fired at another bird centered in my flashlight beam.
However, my aim was a bit low — and the copper pellet hit the steel beam square on. Instantly I felt a sharp pain as the BB bounced back and hit me squarely between the eyes on the bridge of my nose – drawing blood from the partial penetration into the skin. A half inch either way and I’d have lost an eye!
Never, never, never shoot at any target with a steel background with any firearm, even a BB gun – is the hard lesson I learned, and wear the best shooting glasses that money can buy!
PLEASE REMEMBER THAT!!
Editor’s Comment: Among competitive pistol shooters, the use of safety eyewear is universal. You’ll never see Rob Leatham, Julie Golob, or Jerry Miculek competing without eye protection — for good reason. The handgun sports’ governing bodies effectively enforce mandatory eye protection policies. We wish the same could be said for competitive rifle shooting. We often see benchrest, High Power, and F-Class competitors shooting without eye protection. We’ve heard all the excuses, yet none of them trump the safety considerations involved.
We recommend that all shooters and hunters employ eye protection whenever they use firearms or are at a location where live fire is taking place. You only have two eyes. A tiny bullet fragment or ricochet is all it takes to cause permanent blindness in one or both eyes. As rifle shooters, we place our eyes a couple inches away from a combustion chamber operating at pressures up to 70,000 psi. I know quite a few guys who will religiously put on safety glasses when running a lathe or a drill press, yet the same guys won’t use eye protection when shooting their rifles — simply because it is “inconvenient”. That’s nuts. It doesn’t matter is you are a cub scout or a multi-time National Champion — you should wear eye protection.
I will give you a personal example. A year ago I was shooting a 9mm pistol. One of the cartridges had a primer burst outward blowing small particles, some brass, and a piece of the pistol’s extractor right back into my eyes. Thankfully I was wearing good wrap-around safety glasses. No injuries at all. But without those safety glasses, this could have been very serious. I always wear safety glasses with ALL firearms. Shown below is the same kind of primer blow-out I experienced, but with a .270 Win rifle cartridge.
Be wise — protect your eyes. To learn more about eyewear safety standards, and to learn about the latest options in ANSI Z87-certified protective eyewear, read our article on Eye Protection for Shooters.
Do you enjoy shooting pistols for sport, or perhaps you carry a handgun for self-defense? If you’re like most of us, you might benefit from a “refresher course” on the fundamentals of handgun shooting. The NRA has created a useful Infographic that covers important basics of handgun marksmanship — key things such as Sight Alignment, Trigger Control, and Handgun Hold.
Here are the first two (2) lessons. Click the link below to see all SIX (6) training topics: Sight Alignment, Sight Focus, Trigger Control, Breath Control, Hold Control, and Follow-Through.
Video Shows Sight Alignment, Grip, Stance, Trigger Control and More
In this USAMU video, SGT Shane Coley talks about the basics of sight alignment and trigger control. But then SGT Coley talks about other important control factors such as grip, arm position, and body stance. For rapid-fire shooting, you need to have a good arm and body positioning to control recoil and get back on target quickly. This video is a valuable complement to the NRA Infographic because it demonstrates all the important pistol fundamentals during live fire, at the range.
NOTE: If you prefer drying your brass in an oven we recommend a temp setting no higher than 200° F. Better yet, use a dedicated case dryer that cannot possibly over-cook your cases.
Tech Tip by Craig Arnzen of Area419.com
As wet-tumbling brass has become more popular in recent years, guys have tried a LOT of ways to get their brass dry — towels, hair dryers, and even food dehydrators. (See Top Ten Brass Drying Methods). Another common method — albeit with some potential issues — is putting your wet brass in the oven to dry. Provided you monitor TEMP and TIME, this method is fast, effective, and easy (as long don’t use the wife’s favorite cooking pans — that’ll get you in trouble.)
With oven-drying, however, unexpected issues can arise, as illustrated by this worrisome story: “I put my brass in for an hour at 200° F and turned it off. Next thing I know I realize my wife has the oven pre-heating to 350° F. Is my brass ruined?”
If you search the AccurateShooter.com Shooters’ Forum, you’ll find at least three threads with stories like that (i.e. higher-than-expected oven temps when drying brass), and answers on both sides of the line. I know this, because it happened to me — I had some 6XC brass drying and the wife pre-heated the oven. Concerned about my cases, I consulted a genuine annealing expert, Andrew Rixon.
Andrew is the Director of Engineering and Manufacturing at Alpha Munitions, makers of premium-grade rifle brass. I had baked a batch of Alpha 6XC brass, which is exceptionally consistent and well-made. (This 6XC brass is currently out of production, but Alpha produces many other good 6mm cases including 6 PPC, 6mm ARC, 6mm BR, 6 Dasher, 6BRA, 6 GT, and 6mm Creedmoor).
Before Andrew would answer my question though, he gave me a little lesson on what really happens during annealing:
“Annealing is performed by heating the brass to specific temperatures. There are three phases of annealing: recovery, recrystallization, and grain growth. All of which have specific temperatures and or exposure times related to them. It is key for cartridge brass annealing processes to hit the recrystallization phase which allows for strain-free grains to grow. The growth of strain-free grains eliminate dislocations, drastically decreasing hardness and increasing ductility. For recrystallization to occur the material temperature must be within 600-1000 degrees Fahrenheit (F).”
He then got into really answering the question, and was (fortunately) definitive in his answer: “If the temps do not exceed 450 degrees F then there is nothing to worry about as it did not exceed the critical temperature for annealing to occur.” Editor: Caution — do NOT assume that the temperature marked on the oven knob is the actual temperature INSIDE the oven, particularly near the back. Some older ovens can be off as much as 75 degrees F. Be conservative!
Well, there you have it. If you’ve baked your brass, you’re probably OK. If you got it hotter than 450° F then there can start to be some changes to the metal.
