Thanks to a dedicated ‘Down-Under’ benchrester, Australian shooters have an excellent web resource for their sport. Sydney’s Robert Carnell has created a content-rich website for Australian shooters, www.benchrestbulletin.net. Carnell’s Benchrest Bulletin provides match schedules and results, range info, recent news, record listings, shooting tips, and links to important Australian and Pacific Rim shooting organizations. You’ll also find gear reviews and a Shooter’s Forum.
Carnell, a past Australian Sporter Class champion, is an accomplished benchrest shooter with decades of experience. In 1993 he won a Silver Medal at the World Championships, and he has placed highly in events he’s attended in the United States. But Carnell is far more than an ace trigger puller. Robert is a skilled and creative “home gunsmith” who has crafted his own custom action and built his own railguns from scratch. You can learn about these and other Carnellian creations in the “Personal Projects” section of Robert’s website.
Home-Built Rail Gun — Aussie Innovation
Below are photos of one of Rob Carnell’s most amazing builds. This liquid-cooled, tension-barrel rail gun is a great example of self-reliant Aussie engineering. The barrel runs inside a coolent-filled, large-diameter sleeve, much like an old water-cooled machine gun. This is the fourth rail gun that Rob built, and the second fitted with a tensioned barrel.
Robert explains: “My railgun design has a 1.75″ barrel under tension inside an aluminium tube filled with radiator coolant. There is nearly a gallon of coolant, and the barrel stays cool no matter how many shots I seem to fire, or how quickly they are shot. The brass nut on the front rides on a nylon bearing and can be tightened to get the best accuracy. I am a believer in the ‘tuner’ idea and this seems to work for me. The main tube is thick-walled aluminium 600mm (24″) long. There is a flange at both ends. The flange at the back fits onto the barrel before the action is screwed on. The front flange is a press-fit into the tube, then there is a brass nut that fits over the barrel and screws against a nylon washer on the front flange. The Railgun’s base is aluminium and has the standard adjustments — windage, elevation and a sighter cam. In addition, there is a 1/10 thou dial indicator for windage. This allows me to zero the indicator and shoot my group. If I need to add a bit of windage for a condition, I can quickly get back to the original position if my condition comes back.”
Home-Built Action Uses Remington Bolt
Rob’s rail gun uses his own home-made stainless action, which features Panda-spec threads and a modified Remington 700 aftermarket bolt. Not bad for a do-it-yourself project we’d say! CLICK HERE to read how Rob designed and built the action.

There were many European exhibitors at the 2013 SHOT Show, including Kruger Premium Targets from Germany. After a successful first run at the 2012 NRA National Rifle & Pistol Championships in Camp Perry, Ohio, the call for Kruger targets has been picking up steam.
“We are always surprised by how many people come to the show,” said Kruger Sales Manager Joachim Seibold. “For us it is a big advantage because so many people stop by our booth. So many orders.” Now with a state side warehouse located in Oregon, their ability to fill those orders promises to be even quicker than before.

After agreeing to provide the National Rifle Association with targets for the National Championships back in 2010, Kruger has experienced a rise in demand for their product. Especially from the pistol competitions. “I asked many pistol shooters at Camp Perry what they thought about the targets,” explained Seibold. “There were no complaints. Everyone said how pleased they were with the quality. They had no problems seeing the holes, easily scored the targets, and everyone was happy. That’s why the NRA asked us to be their manufacturer.”
That success has created a new demand in the American marketplace. Venturing into the archery industry has been keeping Kruger busy. And a competition target contract with USA Shooting has things humming too. Busy as it is, Kruger has even managed adjust to the strict standards surrounding NRA’s move to the Orion Scoring System. “Yes, we also print targets for the company Orion. Those are in our new Oregon warehouse too,” he concluded with a laugh.
Kruger targets can be ordered online through Kruger-US-Targets.com or you can call Kruger’s USA distributor, MK Tactical, at (503) 746-6816. MK Tactical is located in Hillsborough, OR.
Gary Eliseo of Competition Machine is now offering a tube-gun chassis kit for the Tikka T3 action. This T3 Chassis Kit is the latest design in Gary’s Light Weight Hunter Series. The T3 kit will initially be right-hand only, and will fit AICS short action magazines. This is a “no gunsmithing” installation — no modifications to the action are required and the chassis kit works with the factory T3 trigger and safety.
Tikka’s T3 action is rigid and robust. It cycles smoothly and has a short 75° bolt lift. The T3 features a Sako-style extractor, with angled-leading-edge bolt lugs for smooth lock-up. The T3 action can be installed in Gary’s Chassis Kit with either a recoil disc (and bolts) or glue-in action mounting. The Chassis Kit is designed to accept AR15 buttstocks.
Eliseo’s current T3 Chassis Kit handles short-action cartridges only — for now. Gary is considering bringing out a version with a long-action-length magwell if there is sufficient demand.
Price is $685.00. This includes a rugged Cerakote finish. Tikka T3 action and AICS 5-round or 10-round magazines sold separately. For more info, visit GotXRing.com, call 714-630-5734, or send email to: spraynandprayn [at] gmail.com . CLICK HERE for order page.
Product Tip from EdLongrange. We welcome reader submissions.
There were many semi-auto “tactical” rifles on display at MEDIA Day 2013, but one that caught our eye was the new MR762A1 LRP from Heckler & Koch (HK). The HK MR762A1 LRP (“Long Range Package”) looks similar to the H&K G28 rifle, Germany’s new Designated Marksman Rifle. But the G28 has a steel upper receiver, unlike the MR762A1, which evolved from the HK 417.
Bedecked with quad rails up front, this black and tan rifle screams “tactical”, yet it is surprisingly comfortable to shoot. The grip is comfortable in the hand and the thick rubber buttpad on the adjustable buttstock did a good job of mitigating recoil. Jason said the trigger was crisp and the gun was very accurate. With a gas-piston system (rather than direct gas impingement), this rifle runs very clean. The proprietary, polymer HK magazine worked perfectly with zero feeding issues. We liked these better than the metal mags we’ve tried on other makers’ AR10-type systems.
The MR762A1 is a direct descendent of the HK416/417 series, only in a semi-automatic rifle configuration developed for civilian users. The MR762A1 LRP employs the same HK proprietary gas piston operating system found on current HK rifles and carbines, using a “pusher” rod in place of the gas tube in the original M16/AR15/AR10 design. According to HK, the op-rod design “virtually eliminates malfunctions common to direct impingement gas systems since hot carbon fouling and waste gases do not enter the receiver area. The MR762A1 stays cleaner, reducing heat transfer to the bolt and bolt carrier, and drastically reducing wear and tear on other critical components.”
The MR762A1 uses the same 10- and 20-round translucent polymer box magazines made for the HK417; a 5-round magazine is also under development. Additional accessories and add-ons for the LRP variant of the MR762A1 include an ERGO Pistol Grip from Falcon Industries, the same Blue Force Gear sling used on the HK M27 IAR supplied to the USMC, and an OTIS cleaning kit. The rifle package, complete with one 20-rd mag and one 10-rd mag, is shipped ready to use with the scope attached in a 42″-long Model 1720 Pelican case.
At MEDIA Day 2013, we checked out McMillan’s interesting hydraulic recoil mitigation system for the TAC-50 tactical rifle. Named the TAC-50 A1-R2, this shock-absorbing device reduces the peak recoil from the 50 BMG cartridge by approximately 90 percent (90%). Additional recoil reduction is provided by the proprietary muzzle brake offered on the TAC-50 A1-R2.
The heart of the new TAC-50 A1-R2 recoil mitigation system is a proprietary hydraulic piston in the buttstock. As the rifle is fired, the piston compresses, softening the recoil by lowering the peak recoil force and spreading out the recoil over several milliseconds. The sensation for the shooter is that of a long push, rather than a violent punch.
Without the R2 recoil mitigation system, the peak recoil from a 50 BMG cartridge is approximately 7,500 lbs. of force. From start to finish, the recoil lasts 1 millisecond in a machine rest. With the R2 system, the peak recoil is only approximately 520 lbs. of force. What’s more, the force is spread out over 6 milliseconds. While the total recoil energy is roughly the same, the hydraulic piston lowers the perception of recoil dramatically for a shooter by lowering the peak force and spreading the recoil out over time.
McMillan developed the new R2 system in partnership with customers using the TAC-50 weapons system. Extensive testing with electronic load sensors and high speed photography documented the recoil mitigation. The result is a 50-Caliber rifle that is significantly more comfortable to shoot.

At SHOT Show we checked out a versatile and well-designed new tool from Forster Products — the new Datum Dial Ammunition Measurement System. This handy device measures a variety of important dimensions: 1) cartridge headspace from base of case to shoulder datum; 2) cartridge length from base of case to bullet ogive; 3) bullet base to bullet ogive; and 4) bullet bearing surface (requires two tools).
The complete Datum Dial Kit consists of a dial-holder mount and three precision machined dials. The mount clamps to your sliding-jaw calipers. The mount holds a black ring or one of two supplied gold rings. The black ring has 5 precision-diameter holes that let you check headspace (on shoulder datum) for nearly all modern cartridge types.
Swap in one of two available gold rings to measure to bullet ogive index points. The two gold dials (five holes each) give you 10 different bullet diameter choices, covering the vast majority of common pistol and rifle bullet sizes. This lets you measure both base of bullet to ogive and base of cartridge case to bullet ogive. We really like this dual functionality, as it allows you to quickly sort bullets, plus you can measure your loaded rounds as they come out of the seating die. I have found that accuracy is enhanced when you maintain close base-to-ogive tolerances on your loaded rounds.

Replace a Bin Full of Comparator Inserts
It is important to understand that the Datum Dial system replaces a comparator body and a complete set of caliber-specific comparator inserts. You no longer need a box full of inserts, with one for each caliber that you load. The Datum Dial Complete Kit includes: One dial-holder mount (which clamps on your calipers), one black headspace dial, two (2) gold bullet diameter dials, and a plastic storage box. The Datum Dial Kit is available right now. MSRP is $157.00, and “street price” should be $20 or so lower. Additional dials or caliper jaw mounts are sold separately.
After a massive boycott by dozens of exhibitors and sponsors, including the NRA and Cabela’s, British-owned Reed Exhibitions has “postponed” 2013 Eastern Sports and Outdoor Show (ESOS). The Show, one of the largest Outdoor Expos on the East Coast, was originally slated to open February 2, 2013 at the Farm Show Complex in Harrisburg, Pennsylvania.
The reason for the mass boycott was Reed’s decision to ban the display of AR-platform and similar semi-automatic, magazine-fed rifle systems at ESOS. The announced ban was confusing to many exhibitors because Reed also runs the SHOT Show (for the NSSF) and there was no such ban on ARs in Las Vegas last week. In fact, at SHOT Show, you couldn’t turn your head in the Sands Expo Center without seeing ARs and AR-related hardware on display.
The NSSF stated that it: “is in no way affiliated with, nor does it participate in or exhibit at this show in any way. Reed Exhibitions does, however, manage the NSSF-owned SHOT Show.” Because of Reed’s actions, “NSSF is considering all options regarding the management of future SHOT Shows.”
The NRA declared: “Due to Reed Exhibitions’ refusal to reconsider their decision to ban Modern Sporting Rifles from the February 2-10 Eastern Sports Show in Harrisburg, PA, the National Rifle Association has decided to withdraw from the show. The NRA’s future participation in the Eastern Sports & Outdoor Show will be determined by Reed Exhibitions’ actions in response to the concerns raised by the NRA, the outdoor industry, and America’s law-abiding gun owners.”
At SHOT Show we got a “first look” at the new Kahles K-1050, a 10-50x56mm scope with unique, centerline parallax control. This is a very interesting new high-magnification competition scope. Kahles’s patented centerline parallax control allows the marksman to adjust windage, elevation, AND parallax all with ONE HAND. If you’re in prone position, for example, you simply reach forward with your right hand to dial windage, then slide your hand to the central turret to dial elevation and, finally, set the parallax by adjusting a separate concentric ring.
Watch Video to See Kahles K-1050 Features and Centerline Parallax Control
NOTE: The big-diameter metal ring is OPTIONAL. You can remove the big metal ring and still adjust parallax (from centerline) using a smaller, built-in control ring on the top turret.
Designed for benchrest and field target use, this scope has a 30mm main tube, 55 MOA elevation, and 1/8-MOA clicks. There are three (3) total turret revolutions. The turret “Rev Count” is displayed with a clever red-and-white striped “barber pole” button in the center of the top turret. One red stripe indicates REV 1, red + white indicates REV 2, and red + white + red indicates REV 3. It’s simple, but it works.
The new K-1050 also features a nice European-style +/- diopter control on the eyepiece. If you have less that perfect vision, this allows you to get a sharp target image even without eyeglasses.
We liked the scope. The glass was bright and sharp, and the clicks were positive and precise. Competition shooters have shown great interest in the new K-1050, and Kahles plans to bring the new scope to the USA by mid-summer 2013. Price is expected to be around $2800.00 USD.
At SHOT Show 2013, Lapua announced it was expanding its line-up of Scenar L projectiles to include two new 6.5mm bullets and three new .30-caliber Scenar Ls. We applaud this news. This Editor has tested 6mm Scenar L bullets in his own rifles, and they have proven to be some of the most consistent bullets we have ever measured. The Scenar Ls also shot great in 8-twist barrels from Brux, Krieger, and PacNor.
Two New 6.5mm Scenar Ls
Guys with .260 Rem, 6.5×47, 6.5 Creedmoor, and 6.5-284 rifles have been eagerly awaiting the new 6.5mm Scenar Ls. These will be offered in two weights: 120 grains and 136 grains.
Scenar Ls in .30 Caliber
Lapua will release three new .30-Caliber Scenar L bullets. Along with a new 155gr Palma bullet (GB 552), Lapua will offer a 175gr Scenar L (GB 550), plus a 220gr heavy-weight Scenar L (GB 551). In magnum and short magnum chamberings, the 220-grainers should prove very effective in Long Range comps.
What Makes the Scenar Ls So Good
While all Lapua Scenar bullets are made to exacting standards, Lapua “raised the bar” with its Scanar L series. Scenar L bullets feature closer weight tolerances, tighter jacket wall concentricity standards, and greater uniformity in every dimension. Building bullets this good isn’t easy — you have to get everything right — from the gilding metal cup, to the lead wire and jacket forming, core-jacket assembly, and finally boat-tail pressing and nose-tipping. To build L-series bullets to such high standards, Lapua had to adopt new manufacturing procedures, and install proprietary new machines and advanced instrumentation never seen before in bullet production. Lapua also took its already high quality control standards and kicked them up a notch.
New 6.5mm Scenar Ls — First Look
At SHOT Show, Lapua unveiled its much-awaited new 6.5mm (.264 caliber) Lapua Scenar L bullets. There are two (2) new 6.5mm Scenar Ls: a 120gr tangent ogive design and a 136gr multi-ogive design. These are both all-new bullets, though the new 120gr Scenar L bears a “family resemblance” to the current (and very accurate) 123gr standard Scenar. One look at the new 136-grainer, and you can see that this is NOT just a “tweak” of the popular 139gr standard Scenar. The new 136gr Scenar L has a streamlined secant-ogive shape that blends into a more conventional tangent ogive as the bullet approaches full diameter. This dual-ogive design enhances the bullet’s BC, making it more slippery. That should translate to less drop and less drift at long range.
These new 6.5-caliber Scenar Ls should hit the market very soon. Check with Grafs.com for availability. As soon as we can get our hands on Lapua’s new 120s and 136s we will test them in a 6.5×47 Lapua bench gun and see how they perform. The .30-Cal 175gr and 220gr Scenar-Ls should arrive by late spring according to Kevin Thomas of Lapua. Kevin is a member of our Forum and he can answer your questions about the entire line-up of Lapua projectiles, along with Lapua cartridge brass.
