Report by Richard King (King’s Armory, Texas; ‘Kings X’ on our Forum)
With all the talk from Vince Bottomley in the April issue of Target Shooter about aluminum stocks, I thought you might like to see my latest project. 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.
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 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.
The 30″ barrel is 1.250″ in diameter. 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 haves) being dampened. This is my fourth barrel block gun. They work, but so does a good pillar-bedded action. I just do stuff a little different.
The vertical “keel” down the bottom of the stock stops the “spring” of a flat-bar stock. There is little, if any, noticeable flex before or during recoil. The long length of the stock, the fat barrel, and the forward-mounted barrel block work together to keep the gun from rising off the ground. BUT, remember this is a .223 Rem rifle. A .308 Win version might act very differently. I may try a .308-barreled action soon, just to see what happens. But I will stick with the .223 Rem as my choice for match shooting.
The offset scope idea came from a benchrest “rail” gun. In truth, the whole concept came from a rail gun — just adapted to being shot off a bipod. Sure it isn’t directly over the bore. It is about 1.5″ over to the left. So if you want the scope to be zeroed on the center of the target, you have to adjust for the offset. At 100 yards that is 1.5 MOA. But at 300 it is only 0.5 MOA, at 600 only a ¼-MOA, and at 1000 about 1 click on my scope.
What the offset DOES do for me is eliminate any cheek pressure. My cheek never touches the stock. Since this is only a .223 Rem, I don’t put and shoulder pressure behind it. And I don’t have a pistol grip to hang on to, but I do put my thumb behind the trigger guard and “pinch” the two-ounce trigger.
The offset scope placement could interfere with loading a dual-port action from the left. That’s not a problem for me as I set my spotting scope up on the left side very close to the rifle. I have plenty of time to reload from the right side while the target is in the pits being scored.
Again — this is my rifle. It 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. It might be interesting to offset the wings up from to counter torque of the big bullets. But I would also have to offset the rear bag rider to get the gun to recoil straight back.
How the Gun Performs
I have had “T” to the range only twice for load development. It groups like my present barrel-blocked 223 F-TR gun. But it’s much easier to shoot and it only moves about 3/4” — straight back. I tried to build am omni-directional joy-stick bipod but I could not get all the side-to-side wiggle out of it. So I have set it up so it only moves up and down (horizontal movement is locked-out). As it works now, the joystick on the bipod lets me set elevation on the target quickly (with up/down adjustment). Then, to adjust for windage, I slide my rear bag side-to-side as needed. Once set, I just tickle the trigger and smile.
Gun Handling — Shoot It Like a Bench-Gun
I basically shoot the gun with no cheek or body contact. I don’t grip it, other than maybe a pinch on the trigger guard. The scope was offset to the left to help the shooter move off the gun and avoid the possibility of head/cheek contact with the stock.

Notice tip by EdLongrange. We welcome reader submissions.
LuckyGunner.com, a leading online ammo vendor, has conducted a remarkable “torture-test” comparison of brass-cased and steel-cased .223 Rem ammunition. Four different kinds of ammo (one brass-cased, three steel-cased) were fired through four different Bushmaster AR15s — ten thousand (10,000) rounds PER GUN. The idea was to see if brass-cased ammo was better than the cheaper, steel-cased ammunition. During the course of the project, Luckygunner’s testers logged malfunctions and checked for accuracy, chamber pressure, gas port pressure, chamber wear, and overall barrel wear. At the end of the test, the well-worn barrels were sectioned to see the effect of thousands of rounds… and the results weren’t pretty.
Test Findings: For a multitude of reasons, the test crew determined that Federal brass-cased ammo was “healthier” than steel-cased ammo. The brass-cased ammo shot more accurately, had far fewer malufunctions, and produced less barrel wear. The USA-made brass-cased ammo also showed more consistent velocities. CLICK HERE to READ FULL TEST.
Watch the video below for a summary of results:
Torture Test Procedure
Four types of .223 Rem ammo were tested: Federal brass-cased 55gr FMJBT; Wolf steel-cased (polymer coating) 55gr FMJ; Tula steel-cased (polymer coating) 55gr Bi-Metal Jacket; Brown Bear steel-cased (lacquer coating) 55gr Bi-Metal Jacket. Each ammo type was paired with a specific Bushmaster AR-15. Tests were performed at various round-count stages:
At the start: record accuracy, velocity, chamber and gas port pressures, make chamber cast
After 2,000 rounds: record accuracy, velocity
After 4,000 rounds: record accuracy, velocity
After 5,000 rounds: record throat erosion, make chamber cast
After 6,000 rounds: record accuracy, velocity
After 8,000 rounds: record accuracy, velocity
After 10,000 rounds: record accuracy, velocity, chamber and gas port pressures, throat erosion, extractor wear, chamber cast, barrel wear, make chamber cast.
During testing, rifles were cleaned according to a preset schedule and temperatures were monitored. After testing, LuckyGunner sectioned the barrels and made careful inspections.
Click the links below for specific data, test results, and conclusions:
During the testing process, all malfunctions of each rifle-ammo combination were logged. The brass-cased Federal ammo was the clear winner:
Federal: 10,000 rounds, 0 malfunctions. Brown Bear: 10,000 rounds, 9 malfunctions
(5 stuck cases, 1 mag-related failure to feed, 3 failures to cycle.) Wolf: 10,000 rounds, 15 malfunctions (stuck cases) Tula: DNF (6,000 rounds in alternate carbine, 3 malfunctions)
Barrel Wear and Throat Erosion
Some of the barrels didn’t make it to 10,000 rounds: “The steel cased/bimetal jacketed ammunition caused accelerated wear to the inside of their respective bores. While the barrel of the Federal carbine had plenty of life left, even after 10,000 rounds … the Wolf and Brown Bear barrels … were completely shot out by 6,000 rounds. At the end of the test, the chrome lining of the Wolf and Brown Bear barrels was almost gone from the throat forward, and the barrels had effectively become smoothbores[.] A throat erosion gauge could be dropped into the bore from the muzzle end with absolutely no resistance.”
Colt Manufacturing Company (“Colt”) has finally released T&E versions of the long-promised Colt 901 “Modular Carbine” first revealed in 2011. This rifle shoots both .223 Rem and .308 Win cartridges using the SAME LOWER with different uppers. The Colt accomplishes this task by using a unique magwell insert, along with different mags and buffer assemblies. The 901 is very different than other AR variants which squeeze a short .30-caliber cartridge, such as the .300 AAC BLK, into a .223-length AR magazine. The Colt 901 shoots regular .308 Winchester cartridges, from .308-Win sized magazines. The key is the proprietary magwell insert, which allows standard 5.56×45 (.223 Rem) AR mags to fit inside the lower. To move from .308 to .223, once the insert is in place, you simply switch the buffer spring and buffer, and then attach your .223 Rem upper.
GunsAmerica Review
You’ll find a detailed review and field test of the Colt 901 in the latest GunsAmerica Blog. The testers say the Colt 901 caliber-changing system works as advertised: “It can be adapted from .308/7.62, using standard P-Mags, to .223/5.56, using standard AR mags, and back again, in literally seconds. The design uses one proprietary part, and you have to swap out the recoil system. It is that simple, and it works fantastic…. What [Colt] did was to design a very simple part that adapts both the lug and the magazine size from one size upper to the other. The part itself is made from aluminum, and weighs exactly 3 ounces, including the captured steel push pin. It is simply an adapter, and its genius is in its simplicity.”
The GunsAmerica Review of the Colt 901 is worth reading if you’re interested in a dual-caliber AR. The review offers plenty of photos (zoomable to large size), with close-ups of the magwell insert and the buffer systems. In addition, the reviewers field-tested the Colt 901 with both .223 Rem and .308 Win uppers. Accuracy at 100 yards was not impressive (1.5″ group with the .308, about 2″ for the .223 version), but the reviewers believe the rifle could have shot better with a trigger upgrade.

This month, you’ll find many stories worth reading. Starting off, Laurie Holland hot-rods a Rem 700 SPS tactical rifle. After fitting the rifle with a new 26″ 1:7.9″-twist barrel and Manners Composite stock, Laurie shows that impressive accuracy can be achieved from the upgraded Remington SPS (chambered in .223 Rem). Laurie also continues his on-going series about reloading for the .308 Win. This month he tests Lapua small-flashhole brass with a variety of powders. Other highlights include a comparison test of air-splitters and tuners for airgun benchrest, and a guide to competition optics. Readers can download previous monthly editions plus a Shot Show supplement from the Target Shooter Magazine homepage, found at TargetShooter.co.uk.
Grafs.com is running promotions right now on new products from Hodgdon Powder Co. and Nosler. First, Grafs.com has Hodgdon’s new CFE223 in stock for $21.99 per pound. This new powder is ideal for the .223 Rem and other popular chamberings. We’ve found that CFE223 delivers good velocity and it meters well. Hodgdon claims the proprietary powder formulation can reduce the amount of copper fouling in barrels — so you can shoot more and clean less. What’s more — if you purchase 32 pounds of smokeless powder, Grafs.com will waive the $25.00 hazmat fee, and yes you can “mix and match” different types of powder in your order.
Next, Grafs.com is offering promo pricing on Nosler’s new Varmageddon 40gr, flat-based polymer-tipped Varmint bullets. These new bullets run fast from a .223 Rem. The special tapered-wall jacket design (thin-wall at top, thick at bottom) and the polymer tip assure explosive impact on prairie dogs and other critters. A 100-ct box of .224 cal, 40gr Varmageddon projectiles is just $14.29.
Tikka has started to import its new T3 Sporter, which features an ergonomic, laminated stock, detachable magazine, adjustable cheekpiece and a nice, stiff action with integral dovetail and side bolt-release. The trigger adjusts from 2 to 4 pounds. The T3 Sporter will be produced with 20″ or 24″ barrels in a variety of popular chamberings: .222 Rem*, .223 Rem, 6.5×55 SE, .260 Rem, .308 WIN. We expect this rifle to be popular with tactical shooters and club-level match shooters who want a versatile rifle that can be used for hunting as well as target shooting. The stock is similar to the ISU “standard rifle” design used for 300m position shooting. As you’d expect, it works in all positions: prone, sitting/kneeling, and standing.
T3 Is Accurate With Smooth-Working Action
We first saw the new Tikka T3 Sporter in January, at the SHOT Show Media Day. The gun we sampled had a nice trigger, smooth bolt, and shot quite accurately with factory ammo. Watch the video below for an overview of the T3 Sporter. The Tikka T3 Sporter was developed in co-operation With Finnish hunting and sport shooting organizations. The design goal was to create a rifle that performs in competition, but can also be used for hunting. The ergonomic stock features an adjustable cheekpiece and adjustable buttplate (length of pull can be changed with spacers). An integral rail allows placement of hand-stops, bipod mounts, and attachments so the rifle can be carried with a double-sling, biathlon style. T3 Sporter weight (without scope) is 9 lbs. with 20″ barrel, or 9.7 lbs. with 24″ barrel.
EuroOptic.com Has T3 Sporters in Stock EuroOptic.com has T3 Sporter inventory in stock now, priced at $1695.00. Not all variants have arrived yet*, but we’ve been told that the following models are available: .308 Win 24″ barrel, .308 Win 20″ barrel, 6.5×55 24″ barrel, 6.5×55 20″ barrel, .260 Rem 20″ barrel. 20″ barrels are threaded with a cap (18×1 metric) while the 24″ barrels are unthreaded. View details on EuroOptic’s T3 Sporter Page (NOTE: EuroOptic’s web site may not show the latest inventory, so call (507) 220-3159 for availability.)
*Beretta, Tikka’s parent company, controls T3 Sporter imports. EuroOptic.com informed us that it “ordered all the versions we could from Beretta, but no .222 Rem was available in the USA at this time.” So, for the near term at least, it appears that the .222 Rem will be limited to the European market.
Hodgdon Powder has introduced a new spherical (ball) powder called CFE™223. Hodgdon claims that this new powder “greatly deters copper fouling” compared to other propellants. Originally developed for U.S. rapid-fire military systems, CFE™223 incorporates a proprietary chemistry named “Copper Fouling Eraser”. Based on tests with extended shot strings, Hodgdon claims that, by using CFE™223, match shooters, varmint hunters, and AR shooters can maintain accuracy for longer periods, with less barrel-cleaning time.
Load Data Now Available Online for CFE™223
Reload data for CFE™223 is available for 27 different cartridges with 147 loads. It is suitable for loading in many popular chamberings including: .204 Ruger, .223 Rem, 22-250, 6mmBR, .243 Win, 6.5 Creedmoor, .260 Rem, 7mm-08, and .308 Win. Maximum velocities are obtained in the .204 Ruger, .223 Rem, 22-250, and .308 Win with load data found at Hodgdon’s Reloading Data Center. CFE™223 is a spherical (ball) powder, so it meters well. The new powder will be available in one- and eight-pound containers starting in January, 2012. For more info, call (913) 362-9455 or write to: Hodgdon Powder, 6231 Robinson, Shawnee Mission, KS 66202.
