Witam!
Poproszę o poradę, które wartości przyjąć jako graniczne, które można używać. Chcę przygotować naboje do strzelenia "drabinki" z wykorzystaniem trzech różnych pocisków sierra, prochem RS60, spłonkami murom, łuskami geco z pojemnością wodną 54gr h2o. Poniżej odpowiednie wydruki z QL. Na ile można im wierzyć?
pocisk 168 gr 2200:
Cartridge : .308 Win. (SAAMI)
Bullet : .308, 168, Sierra HPBT MatchK 2200
Useable Case Capaci: 46.723 grain H2O = 3.034 cm3
Cartridge O.A.L. L6: 2.800 inch = 71.12 mm
Barrel Length : 26.0 inch = 660.0 mm
Powder : ReloadSwiss RS 60
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 !
