View Full Version : WWI USGI pistol ammo?

May 1, 2010, 11:28 AM
I am looking to buy some WWI USGI .45 acp ammunition to put in a display case with an O1918 Colt.
I see plenty of Frankfort Arsenal stuff on the auction sites, but it's usually in enormous lots. There's another listing for Remington 1918-dated ammo, though. How can I tell if it's USGI or commercial stuff?

You can tell if ammo is commercial or military ammo by the headstamp. Remington commercial ammo will say something like "REM-UMC 45 AUTO", while the military ammo will say "UMC 18". Military ammo typically has info on who loaded it and when (chambering info is not necessary since they use standard service cartridges), commercial ammo has info on who is selling it and the chamber it fits.

"So this stuff is?"

Made by Remington for the US Military.

You can tell by the plain jane packaging and by the military nomenclature.

Originally the 45acp had two loadings .230 gr military and 200 gr civilian.

Because civilians are easier to kill, presumably?

The 200 grain .45 Rimless Smokeless was for the 1905 Colt auto.
The Army insisted on 230 grains as being as close as the auto would get to the 250 grain bullets of the 1873, 1875, and 1909 revolver rounds.

Not that a civilian is easier to kill than a soldier but because a horse is bigger than a man.
