Australian John Lavaring recently shot a group at 200 yards that would make most centerfire shooters proud. The five-shot group, with all shots in the center 10-ring, measured just 0.93 inches. That works out to 0.44 MOA at 200 — mighty impressive for a .22 LR. Recorded at a Rimfire Fly Shoot benchrest event in Canberra, Australia, this 200-yard target set two new Australian SSAA National records! John was using ELEY Tenex ammunition.

Congratulations to John Lavaring for a spectacular demonstration of how well a rimfire rig can shoot — even at 200 yards. We rarely shoot our .22 LR rifles past 50 meters. Maybe it’s time to start a Rimfire ELR series, with targets at 200 or even 300 yards. What do you think of the Rimfire ELR idea? Leave comments below.

Anschutz 54 Benchrest Rig
The rifle was a Anchutz model 54 Match in a custom benchrest stock. John’s record-setting rig features a barrel block, which you can see forward of the action. Scope is a Bausch & Lomb BR model. We don’t have the round count on Lavaring’s barrel, but good rimfire benchrest rifles can often get 10,000 rounds (or more) of accurate life.

Rimfire Ballistics at 200 Yards
Some folks may be wondering about .22 LR ballistics at 200 yards. Well, with a 25-yard zero, the 200-yard drop for John’s 40gr Tenex ammo is 54 inches, assuming 0.145 G1 BC and 1085 fps muzzle velocity per ELEY website. And at 200 yards, a 10 mph crosswind will push that little bullet 15.3 inches! We’re told the winds were pretty tricky when Lavary shot his record group. This makes his achievement all the more impressive — we have to admire John’s wind-reading ability.

This ELEY ammo has proven to be exceptionally accurate. Here is a short video showing TEN rounds of Tenex shot from a machine rest with target at 50 meters.

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.
