Hej Lunderskov
Her er et bud fra QL på standard data om hylster volume og pibe længde
Mvh
Steen
Cartridge : 7 x 64 Brenneke
Bullet : .284, 150, Barnes 'TTSX' BT 30303
Useable Case Capaci: 58.845 grain H2O = 3.821 cm³
Cartridge O.A.L. L6: 3.307 inch = 84.00 mm
Barrel Length : 22.4 inch = 570.0 mm
Powder : Norma URP *C
Predicted data by increasing and decreasing the given charge,
incremented in steps of 1,0% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !
