Data for the newer AccuBond bullets hasn't been released for QL. Here is some information using the 190 grain CC. There may be sufficient correlation to extrapolate a beginning load.
Cartridge : .30-378 Weath. Mag.
Bullet : .308, 190, Nosler CC HPBT 53412
Useable Case Capaci: 123.136 grain H2O = 7.995 cm³
Cartridge O.A.L. L6: 3.655 inch = 92.84 mm
Barrel Length : 26.0 inch = 660.4 mm
Powder : Alliant Reloder-33
Predicted data by increasing and decreasing the given charge,
incremented in steps of 2.0% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !
