QuickLoad gives the following data. I have no experience with either the bullet or the powder and have not tested these loads. This is provided for information only. Use at your own risk

Code:
Cartridge          : .45 Auto (ACP) (SAAMI)
Bullet             : .451, 200, RN Rainier
Cartridge O.A.L. L6: 1.275 inch or 32.39 mm
Barrel Length      : 5.0 inch or 127.0 mm
Powder             : 12 Vihtavuori N320

Predicted data by increasing and decreasing the given charge,
incremented in steps of 0.813% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !
