I have looked a little but haven't found the info yet. Does anyone know what the mil specs are for the old 45acp? All I really need is the muzzle velocity. I have been told it is 830 fps.
Thanks.

Some of the TZZ ball ammo comes in around 915-930. Smoking hot stuff. I shot many thousands of rounds of the stuff. Not fun. Hard on you and the guns.

I also think it's 830-850 fps

From reading around in a few of my reloading manuals, the 230 grain ball round for the military was designed for 850 fps from the 1911 platform.

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.

" out of spec". That is probably the current "not Libel" load. :supergrin:

WWII & Korean War .45 ammo I've chronographed ran in the 830-850fps range with amazing consistancy.
