The case capacity is different in jon's than what mine shows for a 6x45. Also, I used a different bullet with G7 ballistics... case capacity will make the big difference...
Cartridge : 6 x 45mm
Bullet : .243, 95, Berger Hunt VLD G7 #24427
Useable Case Capaci: 23.582 grain H2O = 1.531 cm³
Cartridge O.A.L. L6: 2.253 inch = 57.23 mm
Barrel Length : 24.0 inch = 609.6 mm
Powder : Hodgdon VARGET *T
Predicted data by increasing and decreasing the given charge,
incremented in steps of 1.5% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !
