Just got my 6mm creedmoor build finished up. 18” carbon six barrel on a atlas tactical action. Sitting in a whiskey 3 chassis. Nomad 30 suppressor and razor gen 2.
Started at 42 grains and .025” off the lands. I jumped 1/2 increments to find pressure. At 45 grains I still hadn’t hit pressure but stopped.
Started OCW at 44 in increments of 0.3grains.
Best groups were 44 and 44.3. Did a 43.7 group afterwards.
Seemed the best groups were around 44 grains so I did .015”, .035”, and .045” jump groups.
.035” shot best at 2.225” LTO.
tried 44.2 grains at this jump as well.
