Hoppe Offers Dasher Tuning Tips
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.
Robert Hoppe is one of the top 600-yard shooters in the country. Last fall, 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. Just last weekend, John Lewis shot even smaller with an IBS Heavy Gun, but Robert’s 0.5823″ still remains the NBRSA 600-yard record, and the smallest group ever shot at 600 by a 17-lb class rifle. Robert has been very successful in the 600-yard game, and he finished 5th recently at the NBRSA 600-yard competition. 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.
