Settled with 31.3gr of LVR.
Speed isn't quite at the target 2750 BUT the accuracy makes up for it. Can throw a 10 shot group at .75,MOA and a 9 shot group before I botch #10 at just a hair under .5MOA
Prone, no rear bag. I'm simulating match position as much as I can.
Ambient temp was around 58-60 per my car. I kind of suspect that the ammo gets colder than ambient temp sitting on a shaded cement pad. I need to bring an infrared thermometer....

I have 27-28.2gr in .3 increments of 8208xbr loaded for tomorrow's session. Same cbto, same 123 eldm. Anything above 2600fps without over pressure would be acceptable to me. Will keep running over magnetospeed, 10x rds each, 5 groups. I feel like a 10 round group will better represent actual group size, and will give me more accurate sd/es off the chrono.
