OK -- with the 120 Sierra go with 30 grains of 2520 or 28 1/2 grains of 8208 XBR, CCI 450 and what Alexander states is his oal. Can't remember it off hand.

The AA data is 2.220 COL
Quantitative is relative to the Hornady 123 A-Max factory load. That should equalize enviornmental conditions.
I don't see a problem with this in the High Power community, nearly evryone gets the same results with the 77 grain Sierra Match King, nearly evryone gets .5 -1.25MOA with Black Hills, Alanta Arms, or Federal Gold Medal Match or Hornady 75 BTHP Factory loads or equivalent handloads. Provided, they can shoot, no chrome bores, no slow twist, 1:8 or faster, doesn't matter 16" or 28".
