Since its introduction in 2001, the .300 Winchester Short Magnum (.300 WSM), has proven very popular for hunting and long-range competition. The case has ample capacity to drive the heavy .30-caliber bullets, and with proper case prep and annealing, the WSM is capable of outstanding accuracy. When Nebraskan Greg Anderson decided to build his “ultimate long-range hunter”, he selected the .300 WSM for its accuracy and its ability to drop large game at long distances. Teaming up with Chris Matthews of LongShot Rifles, Greg developed an impressive long-range hunting rig, with high-tech components to reduce weight. The 26″ barrel is a carbon-wrapped composite over a Rock Creek stainless blank. The carbon technology saved about 3 pounds over an all-steel barrel of similar length/contour.
The Manners Composite stock also features carbon fiber construction for stiffness and reduced weight. Greg’s carbon/carbon rifle tips the scales at just 10.8 pounds, including scope and bipod. A conventional rig could easily weigh 15 pounds or more. Greg’s carbon hunter has proven accurate as well as innovative. With 175gr Sierra MKs, the gun shoots well under 1/2-MOA out to 600 yards and beyond.
The Ideal Spot and Stalk Rifle
by Greg Anderson
The purpose of this project was to create a hunting rifle that would be inherently accurate at long range and have an acceptable weight for hunting in rough country. I researched the question of overall weight with several gunsmiths. The smiths confirmed that while fat-contour barrels could deliver improved accuracy, there was a price to pay and a lot more weight. With a heavy barrel, the finished rifle would be most likely weigh about 15 pounds. That’s more than I wanted to haul around in the field. To reduce barrel weight, the suggested “traditional” solutions were fluting, which would reduce barrel weight by at least one-half pound, or going with a smaller diameter barrel.
The Quest for Reduced Weight without Accuracy Loss
Fluting didn’t promise enough weight savings, and a slim, sporter barrel probably wasn’t going to deliver the kind of consistent accuracy I wanted (particularly as the barrel heated up). Accordingly, I decided to “think outside the box”. My research on lightweight barrel options lead me to Advanced Barrel Systems, (ABS) a company in Lincoln, Nebraska that once produced custom carbon-wrapped barrels. ABS President Mike Degerness could wrap a barrel to virtually any shape and diameter, allowing great stiffness even with a huge reduction in barrel weight. As the “core” for his carbon-wrapped barrels, Mike recommends a cut-rifled blank made by any of the quality cut-barrel makers. [NOTE: ABS is not taking orders at this time. You can now get excellent carbon-wrapped barrels from Proof Research].
Significant Weight Saving with Carbon
How much weight can you save with a carbon-wrapped barrel? Well a 24-inch, #7 contour ABS carbon-wrapped barrel will weigh about 2.5 pounds compared to about 5.5 pounds for a steel barrel of the same length and contour. So, this means that you can put a fat, stiff competition-contour barrel on your hunting rifle and save over half the barrel weight compared to an all-steel barrel. Saving three pounds is a blessing when you’re carrying the rifle all day long in the field. I placed an order for a 30-caliber Rock Creek barrel blank with an 1:11.25″ twist and a finished length of 26″. Mike wrapped the barrel and finished it to an M24 contour.
Carbon Can Also Improve Barrel Vibration Damping
One interesting benefit of carbon barrel-wrapping is that the carbon components have a vibration-dampening effect. According to ABS, the extreme rigidity of the finished composite barrel dampens the vibration nodes of the barrel making it shoot like a plain steel barrel of much greater mass. Carbon fiber has a high modulus of elasticity that has the effect of lowering the amplitude of the vibration of the barrel when fired. This is what makes the ABS barrels perform so well, according to Mike.
Impressive Accuracy For a Hunting Rifle
Looking at the targets below, one may ask, “Does the rifle always shoot this well?” The answer, not surprisingly, is: “it depends on the trigger-puller”. The rifle is capable of outstanding accuracy. But it took some time and effort for me to develop the skills required to shoot up to the rifle’s inherent accuracy. I nearly always practice prone from bipod. Initially, I was getting horizontal stringing until I changed my grip and learned to be more consistent from shot to shot. Shooting a heavy-recoiling .30-caliber rifle from the ground is not the same as shooting a .223 Rem from the bench.
3-Shot Group at 200 yards | 6-Shot Group at 500 Yards
Completing the Project Build
To smith the rifle, I selected Chris Matthews of LongShot Rifles, LLC because of his expertise with the WSM cartridges and long-range shooting equipment. Because cost was a factor, we decided to use a donor Remington long action that had been used on a Remington 7mm magnum. Chris trued the action and we had Dave Kiff from Pacific Tool & Gauge grind us a bolt to fit the action more perfectly. Chris chambered the Rock barrel and installed a .300 Badger recoil lug.
Carbon-Reinforced Hunting Stock from Tom Manners
Being a fan of carbon fiber technology, I selected an MCS-T stock from Manners Composite Stocks. These stocks have an extremely high strength-to-weight ratio and the high comb of the MCS-T gave an almost perfect alignment with the scope. The finished rifle was topped off with a Leupold 4.5-14x40mm LR scope equipped with M1 windage and elevation turrets. A Harris bipod completed the package. All up, including scope, steel rings, and bipod, my .300 WSM rifle with 26″ barrel weighs 10.8 pounds.
Load Development for Accuracy
I developed a load using 63.0 grains of H4350, 175gr Sierra Match Kings with Federal 210M primers in Winchester-brand brass. This load gives 2960 FPS out of my rifle. The load would shoot sub-MOA from bipod from 100 yards to 600 yards and was adopted as the “go to” load. I have also tried the 208gr Hornady A-Max in this gun. The A-Maxs shot well but the Sierras work well for everything (paper punching and hunting) so the 175gr SMK is my bullet of choice.
Brass Prep and Annealing Are Very Important
The Winchester-brand brass is good, but you have to prep it thoroughly if you want good results. My brass prep consisted of turning the necks, de-burring the flash holes (inside and out), and chamfering the case necks. Using a Sinclair neck-turning tool, I turn the necks to .0135″ per side. That provides a complete clean-up of the necks, which run about .015″ neck-wall thickness out of the box.
One thing I’ve learned to do is anneal the brass every 3-4 firings. I started to do that after I noticed that the force required to seat bullets became inconsistent after just a few loading cycles. I also experienced flyers that were going out of the group for no apparent reason. Annealing the cases every 3-4 firings has eliminated most of the unexplained flyers and annealing has also made bullet seating much, much more consistent. I’ve also noticed a significant improvement in my groups at 500 and 600 yards now that I anneal regularly. Group sizes at 600 yards can be as much as 2″ smaller with annealed brass than with un-annealed, work-hardened brass.
Greg Anderson was successful with his .300 WSM on his very first hunt, dropping a nice buck at 364 yards. Chris reports: This was on some private land in Nebraska. As daylight faded… there were a couple of bucks, but one looked to be the best of the lot. The buck gave me a broadside shot ranged at 364 yards. I settled behind the scope and took one shot. It hit right where I aimed and the buck just folded.”

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. Pre-fits are offered for Savage rifles, Ruger Precision Rifle (RPR) series, and SIG Cross rifles. These pre-fit barrels are not cheap. A 6mm Creedmoor RPR pre-fit costs $1449.00, while the Savage pre-fits are also $1449.00 for most chamberings. The carbon-wrapped Helix 6 barrel blanks cost $1249.00 for the listed 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 both Savage and the Ruger Precision Rifle in many popular long-range cartridges. Helix 6 can also thread and chamber a barrel for any precision rifle. 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. Buttoned-rifled barrel calibers are: .224, .243 (6mm), .264 (6.5mm), .284 (7mm), .308 and .338. Cut-rifled barrel calibers are: .224, .243 (6mm), .257, .264 (6.5mm), .284 (7mm), .308, .338, and .375.

When a hunter treks deep into the backcountry, he wants a tough yet light-weight rifle that’s easy to carry. But if the hunter is pursing very big game, such as a mature bull elk, he needs a rifle capable of shooting a large-caliber bullet at serious velocities. That’s what Kelbly’s offers with the impressive Nanook MG rifle. Built on a magnesium chassis, with a 26″ carbon-wrapped barrel and folding stock, the 7.9-lb Nanook MG is a long-range hunting rifle that’s easy to carry, yet can effectively shoot big-caliber cartridges capable of taking very large game.
The Kelbly’s Nanook MG offers the benefits of a chassis rifle with lighter weight through the use of carbon fiber components. Take a look — you’ll see carbon pistol grip, carbon cheek riser, and even a carbon buttstock beam. And the buttstock folds 180-degrees behind the chassis. This allows convenient carry when strapped to a backpack. With its folding stock, the Nanook MG is quite “packable” even with a 26″ barrel that allows high velocities from .300 PRC, .300 Norma Magnum, or .338 Lapua Magnum cartridges.

Nanook MG — Modern Chassis Rifle for the Long Range Hunter
The Nanook MG is a modern, light-weight chassis rifle optimized for medium- and long-range game hunting. Key Nanook MG components are low mass, allowing an overall weight of just 7 lbs. 14 ounces (before scope) even with a 26″ barrel. The heart of the rifle is Kelbly’s new light-weight Nanook action that weighs just 26.5 ounces. The barreled action rides in a magnesium XLR Element 4.0 MG chassis fitted with a carbon fiber hand grip and cheek riser to save those precious ounces. To ease packing the rifle, the chassis is fitted with a folding buttstock. This allows the rifle to have a proper 26″-long barrel to deliver high velocity with big cartridges.
The carbon-wrapped Heavy Palma Contour barrel is crafted by Preferred Carbon and fitted with self-timing Klaw Muzzle Brake. Kelbly’s states these barrels give excellent 3-shot accuracy, enough shots for any hunting situation. That accuracy is aided by a premium Bix’N Andy Dakota trigger set at a crisp 2.5 pounds.
Q & A with Ian Kelbly about the Features of the Nanook MG Rifle
Q: What were Kelbly’s design goals in making the Nanook MG rifle?
Kelbly: Our design goal was to create an optimized long range hunting rifle. We wanted something easy to pack (i.e. light-weight with a folding stock), that still had a fairly long 26″ barrel. This barrel length allows the hunter to take full advantage of the .300 PRC, .300 Norma Magnum, or .338 Lapua Magnum cartridges. We also wanted to showcase our new Nanook action, fitted to a modern chassis rifle that was light enough for mountain hunting.
Q: What are the best features of the Nanook MG Rifle?
Kelbly: There are many important features in this turn-key hunting rifle. The magnesium XLR Element chassis boasts high strength and ruggedness, with no more weight than a synthetic stock. The carbon-wrapped barrel from Preferred Barrels offers ample length for high velocities, but significantly reduced weight compared to a normal stainless barrel. The Bix’N Andy Dakota single-stage trigger provides a super-crisp break with the adjustability of a high end competition trigger.
Q: What factors favor a Chassis Rifle for long-range hunting?
Kelbly: The XLR Element 4.0 MG chassis offers the modularity of a modern precision rifle, including a full-length ARCA Rail for bipod/tripod attachment, but with the weight of a synthetic stock. The chassis also features M-Lok slots for for attaching any accessories that the hunter would want. Another key feature is that this chassis design allows you to fold the buttstock for scabbard packs and easy carrying.
Q: How do the carbon-wrap barrel and folding stock benefit the hunter in the field?
Kelbly: The carbon barrel allows us to remove significant weight from the rifle. We also specify the rifle with a carbon buttstock and hand grip to allow for more weight savings. The folding stock makes transport and packing much easier by reducing the overall length. Carbon barrels are well-suited for hunting, as they have proven to be very repeatable on cold bore and follow-up shots. The only thing a carbon barrel can’t do well is sustained rapid fire for many shots, but that is not needed for big game hunting applications.
Q. What are good chambering options for the Nanook MG Rifle?
Kelbly: We offer the Nanook MG in .300 PRC, .300 Norma Magnum, and .338 Lapua Magnum. All chamberings include a self-timing Klaw Muzzle Brake.
The two-lug Nanook action, at just 26.5 ounces, is extremely light for a steel action. The action body is made of 416R steel while the bolt is 4140 steel. This action features built-in Picatinny rail, while the bolt boasts an aluminum handle plus teardrop bolt knob.

We’re in the thick of hunting season now, so we’re featuring an impressive new hunting rig from Springfield Armory. The new Model 2020 Waypoint rifles feature advanced carbon-wrapped barrels*, TriggerTech triggers, and carbon-fiber, hand-painted camo stocks. The actions are pretty impressive too — with precision machining, enlarged ejection port, and integral recoil lug. These Waypoint rifles rival full-custom hunting rigs, yet are reasonably affordable. Starting price is $1699.00 with stainless barrel, while the deluxe model with carbon-wrapped barrel and adjustable cheekpiece is still under $2,400.00.
Handsome Hand-Painted Carbon-Fiber Stocks
Minimum gun weight with carbon-wrapped barrel and fixed cheek is just 6.6 pounds.
All Model 2020 Waypoint rifles feature strong, light-weight, carbon-fiber-reinforced stocks with hand-painted camouflage finishes. Springfield Armory worked with AG Composites to develop these handsome stocks. You could easily pay $700-$800 just for an equivalent camo-painted stock from McMillan or Manners Composite Stocks.
Four Chambering Choices
The Model 2020 Waypoint is offered in four popular chamberings: 6mm Creedmoor, 6.5 Creedmoor, 6.5 PRC, and .308 Winchester. Those are all desirable options. However, because this is a hunting rifle, we would also like to see a 7mm option, and a larger .30-caliber option. At least the barrel twist rates will allow modern, high-BC bullets: 1:7.5″ for the 6mm Creedmoor, 1:8″ for the 6.5 Creedmoor, and 1:10″ for the .308 Win. All barrels are threaded 5/8-24 for the included SA Radial Muzzle Brake.
TriggerTech Adjustable Trigger and Fast Lock Time
We were pleased to see the Model 2020 Waypoint comes with a very good TriggerTech trigger that easily adjusts from 2.5 to 5.0 pounds. This trigger, as combined with a modern fire control system, achieves a very good 19 millisecond lock time — that rivals some custom benchrest actions, and is up to 45% faster than some other factory actions. FYI, “lock time” is measured from the break of the trigger until the firing pin strikes the primer.
Modern Coated Action with Big Ejection Port — Takes AICS-Compatible Mags
Springfield Armory did a nice job with the action. There is a large ejection port and EDM-crafted raceways. The fluted bolt and the action body are coated for corrosion resistance and smooth operation. Additionally, the bolt features dual cocking cams for ease of operation and tool-less disassembly for maintenance.
Factory 3/4-MOA Accuracy Guarantee
Springfield offers an impressive 0.75 MOA three-shot accuracy guarantee with “with quality match-grade factory ammunition, in the hands of a skilled shooter.” That is actually pretty impressive for a hunting rifle that weighs in under 7 pounds before options (carbon bbl version). You could spent a LOT more on a custom rig and not do much better accuracy wise.
Bottom Line — How Does It Feel and How Does It Shoot?
Respected gun writer and hunter Wayne Van Zwoll tested a carbon-barrel Model 2020 Waypoint for Hunting Digital Magazine. He was impressed with the feel of the rifle, the quality of the components, the crispness of the trigger, the smooth mag-feeding, and the demonstrated accuracy:
“This rifle balances well. Running this rifle is a delight! It slurps cartridges seamlessly from the box and is easy to top-feed with single rounds. The magazine is a cinch to release and easily inserted. Springfield Armory’s Waypoint Model 2020 is notable for its relatively modest price — under $2,400 for even the most expensive version, and a starting price of $1,699 — [and] the quality of its parts and workmanship.
Accuracy — My first three shots, after bore-sighting and two to zero, cut a 0.62″ knot. I printed some more groups, which measured .63″ and .70″. Such accuracy from a rifle that, stripped, scales under 6¾ pounds should please any shooter! It’s also a credit to Hornady’s excellent ammunition.
In sum, the Waypoint offers features and performance now expected of top-rung multi-purpose rifles, without bleeding budgets. It should impress hunters as well as shooters scrambling in cross-terrain rifle competition[.] The first new Springfield Armory bolt rifle in a century has impressed me!”
* The base Model 2020 Waypoint has a fluted stainless barrel. The carbon-wrapped barrel is an extra-cost option, as is the adjustable cheekpiece.

The larger .338 caliber barrels run $945.00.
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.
Standard, Pre-Fit, and Custom Barrel Options
Helix 6 Precision barrels are available as pre-fit barrels for both Savage and the Ruger Precision Rifle in many popular long-range cartridges. Barrel blanks are sold in five calibers from .224 to .338. Helix 6 can also thread and chamber a barrel for any precision rifle. Helix 6 Precision also builds one-off barrels to fit individual needs.

Montana-based PROOF Research has released a revealing new video showcasing carbon fiber firearms technology and the company’s barrel-making process. Viewers will find the 8-minute film an intriguing introduction to composite barrel-making, which employs aerospace carbon fiber wrapped around a steel barrel core. The video showcases the high-tech machines used at PROOF’s production facilities.
PROOF’s CEO Larry Murphy explains that PROOF’s barrel technology is state-of-the-art: “What PROOF Research is doing is bringing disruption into our industry. We’re doing things that have never been done here before. That’s going to help the warfighter, and it’s going to help the average hunter … it’s going to do a lot of things.” The video shows how the company employs aerospace-grade, high-temperature composite materials to build match-grade carbon fiber-wrapped barrels, and composite rifle systems.
Dr. David Curliss, General Manager of PROOF Research’s Advanced Composite Division, and former head of the U.S. Air Force High Temperature Composites Laboratory, explains how aerospace expertise helps in the development of PROOF’s firearms-related products: “We are able to provide premier materials for PROOF Research for firearms barrels applications as well as the aerospace market. We’re probably the only firearms technology company that has composite materials in orbit around the earth.”

Here we spotlight some of the more interesting New-for-2018 Firearms and Accessories. All these products are found in Shooting Industry’s 2018 New Product Showcase.
New Tactical Rifles from Legacy International
Legacy Sports is offering two new tactical rifles, both well-suited for PRS matches and tac comps. The Lithgow LA105 (top, above) comes in both 6.5 Creedmoor (1:8″) and .308 Win (1:10″) chamberings, with 24″ barrels with Lithgow muzzle brakes. The new Howa Bravo (tan stock above), is offered with 20″, 24″, and 26″ barrels in three chamberings: 6mm Creedmoor, 6.5 Creedmoor, and .308 Win. The Howa 1500 action rides in a KRG Bravo Chassis with adjustable comb and adjustable LOP. We’re please to note this rig accepts AICS mags.
Mossberg MVP Precision — Affordable PRS Factory Class Rifle
The New Mossberg MVP Precision is another rifle targeting the PRS Crowd. It features an all-new chassis with a longer fore-end up front and a fully-adjustable LUTH-AR MBA-3 stock in the back. This should be popular. Every rifle comes with an LBA trigger, and 20″ or 24″ threaded and free-floated medium bull barrels are standard. The action features an oversize bolt handle with a Picatinny rail on top. Available chamberings include the 6.5 Creedmoor (no surprise) and 7.62×51 (.308 Win). Mossberg will also offer combo packages fitted with Vortex Viper HS-T riflescope.
New T1x Rimfire Rifle from Tikka — Plus a Lefty TAC A1
Tikka is introducing a new Rimfire rifle, the Tikka T1x. It features a medium-contour 20″ barrel with threaded muzzle, 10-round detachable magazine, and a smooth bolt throw. This will be offered in Both .22 LR and .17 HMR. The rifle boasts the feel and balance of Tikka’s centerfire line, so this can serve as a nice small-bore option for fans of Tikka hunting rifles. MSRP for the T1X is $499.00.
Tikka will also be introducing a 6.5 Creedmoor version of its popular T3X hunting rifle for 2018, along with a left-hand version of the Tikka TAC A1 Rifle, an impressive modular rig priced at $1999.00 to qualify for PRS factory class. South-paws should be happy.
New Rimfire Rig from Europe — Steyr’s Handsome Zephyr II
Steyr’s new Rimfire rifle, the Zephyr II, is offered in .22 LR, and .22 WMR, and .17 HMR. The Zephyr II features a classic European walnut stock with a Bavarian cheek piece, and nice checkering on the grips and handguard. We think this would make a good carry-around varminter, as we bet the Zephyr has good balance and excellent accuracy (based on our experience with other Steyrs). Zephyr II has a smooth-running action, tang safety, and cold-hammer-forged 19.7-inch barrel. Without scope, the Zephyr II weighs 5.8 lbs., including 5-rd detachable magazine.
AR with Proof Research Carbon Composite Barrels from LWRC International
You can’t have a SHOT Show without some interesting new Black Rifles. LWRC International (LWRCI) will unveil some new AR-platform rifles in interesting chamberings. The smaller IC-DI (AR15) line will be offered .223 Wylde and the impressive .224 Valkyrie chamberings, along with the typical 5.56 NATO. What really caught our eye, however, was the larger AR10-platform REPR model, shown above. This will be available in two new variants: 6.5 Creedmoor (all-steel barrel) and 6.5 Creedmoor with a PROOF Research carbon fiber composite barrel. Weighing just 9 lbs., the PROOF Research model is a full 2.8 lbs. lighter than the standard model. Each features an LWRCI tunable gas block, Monoforge upper receiver with integrated rail-base, and ambidextrous lower receiver controls.
The Grayboe RIDGEBACK is a new stock specifically designed for PRS and tactical-style shooting. The Ridgeback is made of a solid, fiberglass epoxy material and features M-LOK sections built into the fore-end, a bubble level behind the action and an adjustable comb that can be re-positioned easily with one hand. NOTE: This preview shows a CAD rendering; production model may vary slightly.
New Savage 110 Models with Adjustable Stocks
For 2018, Savage’s model 110 line-up boasts higher-quality, user-adjustable stocks. The all-new AccuFit system allows shooters to customize length of pull and comb height. The new AccuStock features a rigid chassis embedded in the stock. Savage has a full line of revamped 110s with these enhanced stocks. For example, the Savage 110 Long Range Hunter shown here features a 26″ barrel with brake, and is offered in six calibers: 6.5 Creedmoor, .260 Rem, .308 Win, 300 WSM, and .338 Federal.
How To Carry All These New Rifles…
So how do you hold all these new-for-2018 rifles — and transport them safely back from SHOT Show? Here’s a recently-introduced product that can help — the CaseCruzer Mini 2N2 GunPOD:
We love this thing — it will hold two rifles (up to 35″ OAL) and two handguns, plus mags and a whole lot more — muffs, ammo boxes, you name it. This CaseCruzer Mini 2N2 GunPOD is all you need to transport all your gear to a three-gun match. The case is airline-approved and even has wheels. It ain’t cheap though — MSRP is $535.00. There is also a larger version, the 3N3 GunPod (below) that holds THREE Rifles up to 41″ OAL plus three handguns. Priced at $582.00, the 3N3 holds more but it’s pretty heavy (29 lbs. empty). We like the versatility and sturdiness of these CaseCruzer GunPODs.
Here’s a new barrel option for Savage shooters. Proof Research, a leader in composite barrel production, now offers “Pre-Fit” barrels for Savages. These barrels come chambered and threaded for Savage actions. Pre-Fits are easy to install — just spin them on, set the headspace with gauges, and tension the barrel nut. (Proof Research does recommend enlisting a gunsmith to help with the process.)
With a finished weight under three pounds, these new Pre-Fit barrels are much lighter than conventional all-steel barrels. Proof Research claims that they are “less than half the weight of comparably-sized steel barrels.” But you will pay dearly for that weight savings. As sold by Stocky’s Stocks, these Proof Research Pre-Fits cost $846.99, more than twice what all-steel Pre-Fit barrels from Criterion or Pac-Nor cost. Criterion Barrels currently charges $370.00 for a 26″ Savage or Rem/Age Pre-Fit.
Proof Research claims that its carbon-wrapped barrels shed heat faster than an all-steel barrel. Jason Lincoln, Proof Research’s VP of Engineering, claims that his company’s composite barrels can cool 50% faster than steel barrels, offering reduced point-of-impact shift during extended strings of fire. Is this marketing hype? We have yet to see a definitive test that validates the claims of enhanced cooling…
Proof Research Savage Pre-Fit Options Available
Initially the Pre-Fit barrels will be offered in a “Sendero” profile, very similar to an M24 contour. Available barrel lengths (up to 28″) vary by caliber/chambering (in some cases 24″ is all you can get). The following chamberings and twist rates are currently offered by Stocky’s Stocks:
One thing I’ve learned to do is anneal the brass every 3-4 firings. I started to do that after I noticed that the force required to seat bullets became inconsistent after just a few loading cycles. I also experienced flyers that were going out of the group for no apparent reason. Annealing the cases every 3-4 firings has eliminated most of the unexplained flyers and annealing has also made bullet seating much, much more consistent. I’ve also noticed a significant improvement in my groups at 500 and 600 yards now that I anneal regularly. Group sizes at 600 yards can be as much as 2″ smaller with annealed brass than with un-annealed, work-hardened brass.
