According to the US Military Small Arms Ammunition Technical Manual, the .45 ACP military ball ammunition specs are as follows:
Cartridge length= 1.275 inches
Cartridge weight= 331gr
Propellant type= SR 7970
Propellant weight= 5.0 gr
Chamber pressure= 19,000 psi
Velocity= 885fps +/- 25fps, 25.5 feet from the muzzle
So the velocity range is from 860fps to 910fps at 25.5 feet from the muzzle, which means the commonly held 830-850fps at the muzzle isn't correct. That would be out of spec.
