I don’t have the data in front of me, but I’m pretty sure my load is 43 grains of Varget. I’m not a balls to the wall loader.
The brass i have is new unfired sig sauer brassIf it was my gun and I wanted a "low" accuracy node round I would start powder charge with the Varget at 41 gr and go up .5 gr at a time.
I have found low nodes in the 41.5-43 gr area.
If I wanted high accuracy node I would Not use Lapua brass.. It never worked well in the high node for me.
Winchester cases were king there and with Varget and a 165-168 gr bullet the high node for me was usually 44gr or more.
Work that one up in .3 gr increments.
