In a Colt 1911 Gov't Model , 5" barrel , 230 gr. cast LRN ,
RCBS 45-230-RN , sized .452

4.6 grains of 700X clocks out @ 818 fps

With an additional 0.4 grs of 700X that 893 fps might be closer to 850 fps ... I wonder if the Hodgdon data was fired , like Lyman's , in a Universal Receiver ... which gives a few extra fps than a 1911 pistol ?
