Ammo for a 1891 Argentine Mauser. Is there a differance? I have seen it advertised both ways. Thanks

Bot sure what people percieve to be the difference, but I don't think there is any.

That said, in the 1891 Mauser we've been shooting Prvi Partizan 180gr. SPBT load from AIM surplus in Ohio. Accurate and showa a reasonable and safe velocity over the chrono. Cheap too.
I just got some of this last week (a new lot which I have NOT tried yet) and he still has some left, but not much.

The 174gr. FMJ from the same maker and supplier shoots comparatively poorly in the same rifle (original barrel at 24", looong throat.)

There was a letter in Handloader Magazine from an Argentine ordnance officer. He indicated there was no case length dimension connected with the nomenclature. It is simply 7.65.
There is also some confusion about the headspace and supposed differences between the 1891 and 1909 chambers. From what I can tell the chambers are supposed to be the same head space in spite of an erroneous chamber drawing that originated in the US. I have 2 different old loading dies that produce dangerous headspace in rifles with known good chambers.
The dies were obviously made to an incorrect specification.

Thanks, I didn't think there was a difference.

I think all Argentine 7.65mm Mauser rifles use the same ammo, whether is is called 7.65X53 or 7.65X54. I got some military stuff stamped 7.65X54mm, but it chambers and fires just as well as the Norma stuff called 7.65X53. BTW, the bullets are .314" in diameter, 185-grain FMJBT's. (FM made in Argentina) This same rifle shoots MOA with .308" bullets. (A DWM M1909).
