One of my most favorite long range rounds hands down is the fast twist 6br improved. Performance way beyond the sum of it's parts. This is a pic of one of my latest 1000 yard gong groups. It was shot with 95 grain Berger VLD's at 3030 fps using 31.5 grains of Varget with an sd of 4 fps! The gong is a 9" circle, and the group goes exactly 5"(outside to outside) for the 5 shots. The fifth shot is actually exactly inside the upper right splash (thus leaving a heavier,darker mark) made by the 2nd shot. The bottom edge hit is a .338 300 grain MK from my favorite 2k round, the .338 MOAG. The 6br improved fast twist will typically always shoot this well if I do my part reading the wind flags. Best of all, I can shoot up to 20 rounds on an 80 degree day without toasting my barrel's throat.
