[QUOTE="rammac, post: 1913529, member: 27761"] 41.6 looks like where I'd work around. I'd reshoot a new set a cartridges in increments of 0.1 grain around 41.6 grains. I like 41.6 because as you go from 41.2 to 42 grains the group centers move from .745", up to 1.032" and back to .777" and the centers start and end at the same angle from the POA. If you work around the 41.6gr load you should narrow that group size variation down a bit but and the angle will vary less too. Once you get to the best load try changing the seating depth a little and see if you can squeeze just a little more precision out of the group size. OCW isn't really designed to give you the tightest groups, it's used to give you the most repeatable group accuracy (where the group center impacts compared to the POA). You might have slightly worse precision (the group size) but you should impact the target more reliably under differing environmental conditions and load component variations. [/QUOTE]
