The 165 NABs load work up got interesting. I ended up stopping at 44.5 grains of Varget over Federal 210Ms in Lapua brass at 2.807 OAL, it was clearly right at the top of a "node" and produced a velocity of 2722 AVG with a spread in the single digits. The second group in the wind where I tried to break the shots in the same conditions was right at a half inch CTC.
I ended up quitting on RL15.... Everything else the same, and 44 grains even only went 2612. The RL15 was new stuff (date code said it was about 4 months old)
