Well I have a can of VV N530 lying around... and nothing to load with it.
So decided to see if I can load 44 grains under a 196GR FMJ in my 8x60S.
Since none of my manuals have this caliber... voila Quickload spat out the following data:
Cartridge : 8 x 60 S
Bullet : .323, 196, Sellier-Bellot FMJ-BT 2910
Useable Case Capaci: 57.171 grain H2O = 3.712 cm³
Cartridge O.A.L. L6: 3.291 inch = 83.59 mm
Barrel Length : 24.0 inch = 609.6 mm
Powder : Vihtavuori N530
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 !

Does this mean I am safe to go at 44.5 grains?
