- I recently got a knife bayonet M-1908 used by Uruguay. I know that country imported some Mauser bolt-action rifles chambered for the 7X57 and 7.65X53 rounds. Did Uruguay manufacture 7X57 and 7.65X53 ammo??? If they did, I would like to know about the Uruguayan headstamp markings for the 7X57 and 7.65X53 rounds. Thanks in advance for any help, Liviu 10/25/08
I just searched in municion.org , there is a 7x57 headstamp “AG-ROU 1946” from Uruguay.
