Well.I'm mainly using Varget now because it's reputation for temperature stability and Horndady has the published data and I actually had some on hand. I'm willing to give up some velocity for consistent velocities throughout different times of the year. I'm in Kentucky and we definitely have 4 seasons of weather. I dont shoot much in Winter. I would love to truly know how Staball compares to Varget in termperature stability from 45-95 degrees temperature.
Out of curiousity I looked up data from the Hodgdon book/mag, it has the sierra 107 using varget, 25.8 compr and 51.6 ksi.
Would you want to try a better powder? Lever, CFE, even Staball is in there for the Hodg data... ball powders work better due to the smallish case capactity.
Don't think I've tried varget for any 6Arc except down in the 90 gr area.
My goal with 6mm ARC in the AR-15 is to shoot IPSC steel targets at 1000 yards and hit more times than I miss. I think I really only need 2300 FPS with the Hornady 108 grain ELD Match bullet to stay supersonic to 1000 yards but obviously the more velocity the better to help with wind. I was thinking Varget might do the job and be really consistent in velocity throughout the year.
