I just came across a handful of loose .45 ACP military rounds. I can decipher all of the headstamps except one. It reads U.S.C.CO. over 18. Can someone tell me who made this ammo? The rest of the rounds are mixed, dating from 1918 to 1943. There is one round of Frankford Arsenal that is dated 35. If anyone needs a round or two of a particular date or manufacturer, drop me an e-mail.
