Shot the 260 load today. 44.0 grains of H414 with a WW magnum primer. It shot well and averaged 2893 fps from the 22 inch barrel of my All Weather Ruger. My 308 load was 47 grains of Varget with standard ww primer. This load clocked 2729 fps average. 22 inch barrel, Browning A-Bolt light weight stalker. These should both be good deer loads for this fall.
