CMP Readies Electronic Target System for Oklahoma CMP Games

CMP Traveling Kongsburg electronic targets acoustic

Report by Johnny Fisher
The Civilian Marksmanship Program has just finished temporary installation of 15 traveling electronic Kongsberg Targets at the Oklahoma City Gun Club in Arcadia, OK. These high-tech targets will be employed during the Oklahoma CMP Games, slated for April 6-10, 2016. All the High Power rifle events during this year’s Oklahoma Games will be run exclusively on these electronic targets. Competitors will be scored electronically with match results being processed in real-time. Notably, this means High Power competitors will not have to do “pit duty” the entire week since manual target-pulling and shot-marking is no longer required.

The majority of shooting at the Oklahoma CMP Games will be fired at the 200-yard line for the Garand / Springfield / Vintage & Modern Military (GSMM) matches. However, the electronic targets have also been readied for use in the scheduled Excellence In Competition (EIC) and Vintage Sniper matches. Those events require additional firing from 300 yards and 600 yards.

Electronic Target Technology — How Kongsberg Targets Work

CMP Targets technician Bryan Parris explains what makes these targets so special: “These targets were designed by the experts at Kongsberg Targets exclusively for the CMP to fit the standard US target dimensions of 72″ square target backers. What shooters discern as the black of the aiming bull is actually black rubber sheeting that is the entire size of the backer. A layer of white corrugated plastic then covers this rubber with a center hole having been cut out to reveal the appropriate sized bull for that yard-line. All that is required as competitors move further back through the course is to change out the plastic cover to reveal a larger aiming black.”

This acoustically-scored target system uses four microphones to locate the bullet as it passes through the target. The microphone closest to the bullet traveling through the target actuates the remaining three to triangulate the exact shot location for the scoring system and simultaneously display the shot on the shooter’s monitor.

Behind the coroplast face and inside the foam insulation, the target is wrapped with rubber to form a type of chamber. This helps insulate the target’s four microphones stay insulated from extreme temperature changes and also helps keep out ambient noise. This chamber need only exist to the extent that it separates itself from the other targets. Parris states: “We’re building these targets to last a great long while. They are extremely durable and can have anywhere from 3000 to 5000 rounds fired through them before any maintenance is required whatsoever.”

The entire system can be powered via battery, generator, or combination of both. The target line communicates wirelessly with the firing line computer system for timing courses of fire and recording scores. And of course, there is virtual real-time communication with monitors set up on each firing point to display shot / group location and value.

When fully assembled, each target weighs about 200 pounds. They are a little cumbersome in their current form, but the CMP’s target technicians are “still working some things out [for] potential future travel games.”

Registration Still Open for Oklahoma CMP Games
The 2016 CMP Oklahoma Games will be held at the Oklahoma City Gun Club in Arcadia, OK from April 6 – 10, 2016. Registration is still available. For more information about these Kongsberg Electronic Targets, contact Bryan Parris of CMP Targets at (256) 835-8455 or bparris@thecmp.org.

Details of Jackie Schmidt’s .1118 100-Yard “Agg for the Ages”

As word spreads of Jackie Schmidt’s historic 0.1118″ 5-target 100-yard Heavy Varmint Aggregate, many readers have inquired about Jackie’s gear and loading procedures. Interestingly, Jackie tells us that he selected the 30 BR “on a whim” for the Heavy Varmint stage of the Midland tournament, after he couldn’t get his 6 PPC Light Varmint gun to shoot up to his standards. With the PPC, he was getting some erratic vertical, with one shot popping up to spoil the group. Jackie turned to his trusty 30 BR, and, as they say, “the rest was history”. Jackie says his 30 BR “held perfect tune all day long”, with “absolutely no vertical”. Here are some other interesting facts about Jackie’s amazing 0.1118″ 5x5x100 Agg and the 30 BR he steered to the pending NBRSA record.

Jackie Free Recoils his 30 BR
Unlike many 30 BR shooters who shoulder their guns, Jackie shoots his 30 BR totally free recoil: “The only thing I touch is the trigger. I try to keep my body out of the equation. Free recoiling a 30 BR isn’t that difficult with a true 13.5-lb rifle.”

Jackie Didn’t Clean During Record Agg
Jackie shot his entire 100-yard HV Aggregate (25 rounds plus sighters) without cleaning his 30 BR rifle. Jackie told us: “I never cleaned the rifle until the end of the day. In fact I never took the gun out of the bags.” Jackie tells us that shooting a full Agg without cleaning has become standard practice with 30 BRs: “We’ve all learned that you don’t have to clean them. It’s a phenomenon of the 30 calibers. They shoot just as good on the last shot as the first shot.” When he does clean, Jackie uses patches soaked with Butch’s Bore Shine, followed by 10 strokes with a wet brush, then dry patches. Jackie adds: “For the past few years, I’ve never put any solvent but Butch’s in my bores.”

Hodgdon H4198 powderJackie Used 100% Case Capacity Charge
Jackie loaded a “100% usable case capacity charge” of Hodgdon H4198 (Extreme) in his rounds. His 112gr BIB bullets are “just kissing” the top of the powder column. To achieve that fill level, Jackie uses an 8″ drop tube. “That’s an old PPC-loader’s trick,” Jackie tells us. He added that his lot of H4198 is slower than most. He’s found that “some guys can reach the 3000 fps mark using nearly a full grain less powder than me.” But we wonder if loading at 100% of case capacity helps with accuracy? Folks with a faster lot of H4198 might not be able to reach 100% case capacity.

Jackie Schmidt’s ‘Snubber’ Tuner — The Inside Engineering
Everyone wants to know about Jackie’s “snubber” tuner, shown in the photo below. The Tuner is made from aluminum and brass and weighs 5.5 ounces. The tuner is 2 5/8″ long and extends past the true crown 5/8″. The inner cylinder is aluminum while the outer section is a marine bearing consisting of a brass shell with hard rubber vulcanized to the inside diameter. (These brass/rubber marine bearings are used for propeller shaft seals). The sandwiched brass/rubber bearing is then pressed on to the central aluminum shaft. The hard rubber helps dampen vibration. The tuner screws on and then is “locked” in place with a split clamp (the last 2″ of the barrel is threaded).

Unlike most tuners which have a fixed base and forward, rotating ring, Jackie’s tuner is one integrated unit. To adjust tune, Jackie’s “snubber” tuner is unclamped at the base and the whole assembly is screwed in or out on the threaded barrel. Jackie machined a very tight-pitched barrel thread so a full rotation of the tuner produces only .028″ of fore and aft movement. Jackie tells us that, once the basic position is set for a barrel, it doesn’t take much rotation to set the tune. He can usually optimize the barrel tune with less than 1/2 turn of the tuner. After the tune position is set, the split clamp at the inboard end is tightened. This way the tuner is basically locked in place while shooting.

Despite numerous requests, Jackie does not sell his tuners commercially. But someone with good machine skills could build a clone tuner. Team USA benchrest shooter Gene Bukys crafted a similar snubber-type tuner which he used successfully at the 2009 World Championships in South Africa.

The “25 Shots Heard Round the World”
Even people outside the Benchrest community are excited about Jackie’s 0.1118 Aggregate. Jackie’s achievement was noted by Michael Bane and broadcast on the Downrange TV Weekly Video Podcast.
