6mm Dasher Load Tuning — Tips from Robert Hoppe

The 6mm Dasher is based on the 6mm BR cartridge with the shoulder blown forward about 0.100″ and “improved” to 40°. Case capacity is raised to about 41.0 grains. This allows the Dasher to drive 105-108gr bullets comfortably at 2970-3000 fps without over-stressing the brass. A popular load used by many successful Dasher shooters is 33.3 grains of Reloder 15, CCI 450 primers, with 105gr Berger VLDs, .010″ in the lands. This is a “warm load” and should only be used with fire-formed brass. As with any load, start 10% low and work up. You may also have good luck jumping the bullets .020″ or more.

Robert Hoppe, one of the top 600-yard shooters in the country, was the 2009 NBRSA 600-yard champion. In 2007, shooting a 6 Dasher, Robert nailed a 0.5823″, 5-shot group. At the time it was the smallest group ever shot in 600-yard registered benchrest competition. In 2008, John Lewis shot even smaller with an IBS Heavy Gun, but Robert’s 0.5823″ still remains the NBRSA 600-yard record, and we believe it is the smallest group ever shot at 600 (in registered BR competition) by a 17-lb class rifle. Robert has been very successful in the 600-yard game, and is one of the best 600-yard shooters in the West. He knows how to wring the best accuracy out of the 6mm Dasher cartridge. Here Robert offers some tips on load development and tuning for the 6mm Dasher.

New Hydraulic Buffer for .308-Win AR-10 Style Rifles

With a standard AR-15 we’ve never had problems with the standard coil-spring-equipped buffer system (other than the annoying spring noise). But with the AR-15’s big brother, the heavier-recoiling AR-10, an enhanced buffer system is welcome. A upgraded buffer won’t reduce recoil force, but it can soften the perceived recoil pulse, allowing the shooter to get back on target more quickly while reducing shooter fatigue over an extended string of fire.

Buffer Technologies of Jefferson City, MO, has introduced a new hydraulic buffer for AR-10-type rifles. Priced at $99.95, the hydraulic buffer weighs 0.38 pounds, has a 5.8-inch compression length, and fits AR-10s with full-length buttstocks. The buffer, crafted from black-oxided steel and black-anodized aluminum, is optimized for use with the .308 Winchester cartridge.

Buffer Technologies claims that its hydraulic buffer can help prevent failures of internal parts and optics by reducing shock and taming recoil. According to Rob Parham, Buffer Tech’s Military/LEO Sales Director: “Our new buffer makes a great gun even better, while protecting the valuable accessories on the firearm. This product is great in assisting target acquisition and allows for quicker follow-up shots.”

Rhode Equals World Record and Wins Beijing ISSF World Cup

Kim Rhode Olympic shotgunAmerica’s four-time-Olympic medalist Kim Rhode won the Gold Medal and equaled the existing world record at the 2010 ISSF World Cup in Beijing, China. Chinese shooters Shi Hong Yan and Wei Ning finished second and third, respectively.

Rhode was nearly perfect throughout the competition. By nailing 74 of 75 targets in the first three rounds and shooting a final round of 24, Rhode won the competition by two targets. With this victory, Rhode has earned more valuable points in her quest to again represent the United States in the 2012 London Games. If Rhode does participate in the 2012 Games, she could become the first American Olympian from an individual sport to earn medals in five consecutive Olympic Games. Rhode was pleased with her performance: “This is an exciting time for me. I was hoping to get a 99 [to set a new record] but it just was not meant to be.” On competing again in Beijing, Rhode declared: “This city is so incredible. Things are a lot different now than they were during the Olympic Games but it still is such an amazing place to compete.”
