McMillan Stocks has released an updated version of its .50-Cal benchrest stock. The new Super 50 BR features an extended-length “wheelbase” with machined aluminum lower surfaces for stiffness and improved tracking. In the video below, Kelly McMillan reviews the features of the new Super 50 BR:
The notable features of the new Super 50 benchrest stock are machined aluminum shoes on the bottom of the forearm and buttstock. These are machined true to each other for perfect alignment in the bags. The removable forearm shoe is available in either a 3.5” or 5” width. This is significant. Kelly McMillan explains: “You’ll be able to shoot this same stock in different classes just by changing the forearm shoe, and that’s something you can do in a match if you want.”
Engineered to be Super-Strong with Minimal Flex
With the interlocking design of the foreand (with 90° blocks that interlock with the aluminum shoe), this is a very rigid stock. In fact, Kelly says: “We’ve molded several 90° angles [into the fiberglass section] that actually increases the stiffness in addition to the stiffness that the aluminum offers. We think this is probably the stiffest fore-end on any stock that we’ve ever made.”
This Super 50 BR stock is approximately 44” long and has a forearm about 20.75” long from the front of the action. And if that’s not long enough, the forward “shoe” can be machined up to 6″ longer to extend the “wheelbase” even further. This stock has a minimum weight of about 9 pounds in Light Gun configuration and a max weight of about 18 pounds (for the stock itself) as a Heavy Gun stock. The Super 50 BR is an ambidextrous design that may be inletted and used both right and left-handed.
It’s important to use a good-fitting bore-guide whenever you clean your barrel. A good bore-guide will keep solvents out of your action and help your cleaning rods run straight and true.
Not all bore guides are created equal. Some offer a sloppy fit and/or fail to seal your chamber effectively. 21st Century Shooting has changed all that with a new generation of chamber-specific Bore Guides. These have a close fit (with O-rings) to seal your chamber completely. The design is intelligent — these bore guides are long enough to extend well past the end of your scope, while the minimal rod diameter provides sufficient clearance for most combs. Priced at $49.99, these high-tech guide rods are custom crafted to fit many popular chamberings: 220 Swift, 223 Rem, 22-250, 6PPC, 6mmBR, 6 Dasher, 6×47, 6-284, 6mm Shehane, 243 WSM, 6.5×47 Lapua, 6.5-284, 6.5 Shehane, 6.5 WSM, 25-06, 270 WSM, .284 Win, 7mm Shehane, 7mm WSM, 30 BR, 308 Win, 30-06, 300 WSM.
Email John [at] 21stcenturyshooting.com to ask about your application. These chamber-specific guide rods are designed fit actions with BAT bolts or Rem 700-style bolts (Borden, Kelblys, Ruger, Savage).
In addition to the new chamber-specific Guide Rods, 21st Century just released a clever new product for shooters who regularly swap barrels (or who need to clean dismounted barrels). If you have a switch-barrel rig, check out 21st Century’s new Barrel Off Bore Guides. Like the full-length 21st Century bore guides, these are manufactured specifically for your chamber, for a perfect fit. These chamber-specific “Barrel Off” bore guides cost $19.99.
Product Tip from EdLongrange. We welcome reader submissions.
Warner Tool Company (WTC) has introduced a new series of “Flat Line” ultra-high-BC bullets. These sleek, lathe-turned solids are some of the most perfectly-streamlined projectiles ever sold. The Ballistic Coefficients (BCs) of Flat Line projectiles are as much as 20% higher than other match bullets of similar caliber and weight. For example, the .30-caliber 200gr Flat Line bullet has a claimed G1 BC of 0.780. Compare that to 0.555 for the Sierra 200gr MatchKing and 0.622 for the Berger 200gr Hybrid.
The new Flat Line bullets all show extremely high Ballistic Coefficients for their weights:

WTC also claims that Flat Line bullets can be launched at faster velocities than other bullets of similar caliber and weight. In its marketing materials, WTC says that Flat Line bullets deliver “Higher velocities when compared with projectiles in its weight class [and] much higher velocity when compared with projectiles of similar BC.” For example, WTC claims that “the 155.5gr .30-caliber bullet has the velocity of a 125-135gr bullet [with] the BC of a 185-200gr bullet.” It will be interesting to see if these claims can be verified in field tests.
Here are comparative G1 BCs for a variety of large .30-caliber bullets:
Cal Zant of the Precision Rifle Blog has obtained some early-production Flat Line bullets from their designer, Josh Kunz. Zant has written a lengthy article explaining the design and features of the new Flat Line bullets. If you are considering ordering some of these new lathe-turned solids, you should definitely read Zant’s report.
These bullets were designed by Aerospace engineer Josh Kunz using advanced computational fluid dynamics (CFD) to simulate supersonic air flow around the bullets. Through the use of advanced modeling and precision CNC machining, Kunz has developed extremely uniform, ballistically “slippery” bullets that fly faster and flatter than other projectiles of similar weight/caliber.
Premium Pricing: Flat Line Bullets Cost $125 to $165 per Hundred
These new Flat Line solid bullets are pricey. The 155s cost $1.25 per bullet and the price goes up from there. If you need large quantities of projectiles for a week-long match, the cost can be daunting. One hundred fifty of the 200-grainers will set you back $435.00! Here is a price list for the new Flat Line bullets. All quantities are in boxes of 50. Pricing is introductory and subject to change.
.30 Cal 155 grain
$62.50 per 50-ct box ($1.25 per bullet)
.30 Cal 180 grain
$67.50 per 50-ct box ($1.35 per bullet)
.30 Cal 200 grain
$72.50 per 50-ct box ($1.45 per bullet)
.338 Cal 255 grain
$82.50 per 50-ct box ($1.65 per bullet)
Is the cost worth it? When you look at the overall expense of attending a major match, and the fact that the top places in big matches are sometimes are decided by a single point (or X-Count), some competitors will spend the extra money for these ultra-high BC solids.
The new F1 Chassis System from Competition Machine is now in production. This straight-line, all-metal chassis with ultra-low bore axis is optimized for F-Class competition. Designer/builder Gary Eliseo tell us that Competition Machine is now accepting F1 Chassis orders for fall 2015 delivery. To order or if you have questions, email Gary via his website contact page.
Gary tells us: “The new F1 Chassis System, designed specifically for F-Open class, has already begun to rack up awards. The system has several innovations that make it an excellent choice for your next build.” F1 Chassis has many design features that improve tracking and tame torque effect:
Low COG — Super low rider fore-end keeps the center of gravity as low as possible
Long Wheelbase — The long separation from front of stock to rear bag-rider improves tracking and reduces the tendency to jump or twist (torque).
Adjustable Offset — The bag-rider section of the fore-end can be adjusted left to right. This adjustable horizontal offset allows you to choose if you want the fore-end offset left, right or center.
Adaptable to All Shooters — The F1 Chassis System features adjustable length of pull, buttplate drop, and cheekpiece height.
Unique Bonded Barrel Block™ System
Stress is the enemy of accuracy. For this reason the F1 Chassis system features a “zero stress” barrel mounting system which uses a barrel block securely bonded to the barrel (with an epoxy-type adhesive). This allows the action to float, relieving all stress from the threaded joint between the barrel and action and all flexing of the action. With this unique “floating action” design, the F1 chassis is compatible with ANY round rifle action. Replacement barrel blocks are available so you can run multiple barreled actions with your F1 chassis. When it’s time to replace the barrel, the barrel block can be “unbonded” and adapted to a new, same-diameter barrel.
USA F-TR Team Captain has a new competition rifle, which features the brand new McMillan F-TR stock. Ray is very pleased… “It’s like Christmas”, he says. The reduced mass of the new McMillan stock helps F-TR shooters “make weight” more easily. Ray tells us:
“This McMillan stock really changes the weight budget. Kelly McMillan updated his three-way buttplate design to make it substantially lighter and the stock itself has a very light fill. Fully assembled, with a 29″ HV-contour barrel (.900″ at muzzle), Duplin bipod, and Nightforce NXS scope, the rig is about 10 ounces under weight. Switch to a Nightforce Competition scope and it will be 14-15 ounces under.” Ray says he could run a slightly longer barrel and still make weight.
Initially, Ray will install a Jewell trigger in the rifle, but he hopes to try out a Bix ‘N Andy trigger in the future. Made in Austria, the advanced Bix ‘N Andy trigger (shown below), features ball bearing internals for an ultra-smooth, creep-free pull and very short lock time.
First revealed at SHOT Show 2014, the Steyr SSG Carbon is finally making its way to America. It took Steyr 16 months to fill a large quantity of LEO orders, but now the innovative Steyr SSG Carbon should be available throughout the USA for $3695.00 MSRP. That sounds pretty expensive, but this is a very sophisticated rifle.
Here’s a very cool video — worth watching full-screen in HD.
The SSG Carbon is based on Steyr’s SBS action (with a +20 MOA rail on top). This gun features the same crisp, adjustable single-stage trigger used in the vaunted SSG 08. The rifle has a hammer-forged, four-groove 1:10″-twist barrel (20″ or 22.4″) chambered for the .308 Winchester. The SSG Carbon rifle offers excellent ergos, with adjustable cheek piece, adjustable butt plate, and an integrated adjustable rear mono-pod. But the real selling point for this rifle is the stock — a carbon stock built like a Formula 1 car chassis.
Chipped Carbon Stock Construction
Unlike conventional carbon-fiber stocks made from woven carbon fabric, the SSG Carbon’s stock is made using the same “chipped-carbon” Sheet Molding Compound (SMC) construction used to create load-bearing structures in Formula 1 racecars and high-performance aircraft. The SSG Carbon’s chipped-carbon flakes combine thermally with the binding agent to form the SMC for a distinctive appearance to the stock. The carbon chips interlock with each other to create a “tension net” that is superior to steel, at a fraction of the weight of steel or even aluminum. Steyr claims that the SMC stock material absorbs recoil better than wood, metal, fiberglass or other synthetics.

Reactive targets — whether balloons, steel gongs, or clay birds — always add fun to a range session. But precision shooters may want something more challenging (i.e. smaller) than a clay bird when shooting inside 300 yards. For a change of pace, try shooting at inexpensive pool cue chalks. Less than 1″ square, these will test your marksmanship skills.
Pool Cue Chalks — Cheap, Fun, Dramatic
If you’re looking for a small target that makes a nice big cloud of color when hit, try pool cue chalks — those little blue cubes you use to dust the end of billiard cues. Measuring about 7/8″ per side, billiard chalks make very challenging targets at 100 and 200 yards. When you hit them, if you nail the circular “dimple” in the middle, they disintegrate impressively, tossing blue “smoke” in all directions. Billiard chalks are inexpensive. You can buy a dozen chalks online for about $3.00 — just 25 cents each. And the prices drop with more quantity. One gross of chalks (that’s 144 pieces) costs just $19.95 at ozonebilliards.com.
To see actual hits on chalk at 100 and 200 yards, watch the video above. (WARNING: Soundtrack is loud and advertisement may play before movie.) The movie-maker, Phil of the Random Nuclear Strikes Blog, cautions that: “You’ll notice (in the video) that some of the hits are ‘wiffs’ instead of ‘poofs’. If you look at the picture above, you’ll see the 1/2 inch dimple in the cube face. If you don’t put the bullet in that dimple, it’ll ‘wiff’ on you.”
Here’s a handy new item, particularly if you load large quantities of bulk ammo for a variety of firearms. Lyman’s new Ammo Checkers check the diameters of reloaded rounds and factory ammo, so you can quickly confirm that your ammo fits a standard chamber. Just drop your loaded rounds in the Ammo Checker, and if the round fits into the gauge, it will fit in the gun’s chamber.
Lyman Ammo Checkers are multi-caliber — each orange block checks six or eight different cartridge types, with each caliber/cartridge name engraved on the gauge. Ammo Checkers are machined to SAAMI minimum chamber dimensions from solid blocks of 6061 T6 aluminum. Ammo Checkers are available in three versions covering most common handgun and rifle calibers:
Why Use a Case Gauge?
We find that case gauges like the Lyman Ammo Checker are particularly useful for handgun reloaders using progressive presses. The chambers of many popular semi-auto pistols are partly unsupported. This allows the case to swell in the bottom quarter. The case may not be sized adequately by your sizing die, which can lead to misfeeds or malfunctions.
Additionally, if you have loaded a large quantity of ammo for a semi-auto rifle such as an AR15, it’s not a bad idea to check your cartridges before you load them into your magazines. All you need is one mis-sized round to cause a stoppage. That will ruin your day if you are competing in a Service Rifle match or 3-Gun event.
Howa now offers “Mini Action” rifles with actions that are nearly an inch shorter than typical “short actions”. With the Mini Action, the chamber and bolt are 12% shorter than regular short actions with shorter bolt throw for faster reloads. Weight is also reduced with a shorter bolt. The Howa Mini Action rifles come with ten-round, synthetic detachable box magazine and a reasonably light HACT 2-stage trigger. This makes for a nice, compact (and very shootable) varmint package. Nice enough, in fact, that we are looking seriously at the Mini-Action Howa as a donor for a .221 Fireball varmint gun project. We like the idea of a shorter action with a compact 10-round mag.
Howa Mini Action rifles chambered in .223 Rem are available now with 20″ lightweight, 22″ standard and 20″ heavy barrel options. Other chamberings, including the .204 Ruger, will be available soon. Synthetic stocks designed to fit this new Mini Action configuration are offered in black, OD green, and Kryptek Highlander camo colors.
Here’s a smart new product that could save your life (or the life of a loved one). The EPIC-id bracelet stores your vital information on a shockproof, weatherproof USB flash drive that can be instantly accessed by an EMT or doctor. Your Editor just bought two of these med-info bracelets — one for himself and another for a diabetic family member. If you’re a shooter, or spend much time outdoors, you should have this device or some other kind of tag that provides your vital info (such as blood type and drug allergies) to first responders.
If you’re injured, first responders need to know if you have a medical condition, have drug allergies, or take any medications. With this bracelet, that vital info is available even if you can’t communicate. The EPIC-id Emergency Band stores medical data on a USB flash drive that can be “read” by any computer or mobile device with a USB port. Firefighters, EMTs, and medical professionals can instantly determine your name, emergency contacts, insurance, and medical information. (Read my experience below).
It’s easy to load your medical data on to the device. Standardized emergency info forms come pre-loaded — just insert the Epic-ID into any computer to fill out the forms. PC and Mac™ compatible, the waterproof EPIC-id features a durable stainless steel clasp and trim-to-fit silicone band.
Editor’s Story — Why This Is Important
Just this past Wednesday July 8th, at 2:00 am, a family member was rushed to the hospital after suffering a stroke. She was non-responsive and unable to communicate at all. This created problems for EMTs because they were unaware of her current medications, insulin needs, resusitation preferences, and some relevant past medical history. After that experience I decided to buy these bracelets for her and myself. The good new is that she survived… but it was close.
