The 7.65x53 and the 7x57 Mauser cartridges were designed by Paul Mauser in 1889 and 1892 respectively. The 7.65x53, based on the rimmed Mauser 7.65x53R cartridge, was designed for the 1889 Belgian mauser and used in the 1890 to 1903 Turks, and Argentine rifles up to the 1970's. 7.65x54 is really a rounding up mistake as the real case length is about 53.4 to 53.6mm
The SF ammo I tried, don't remember the year, was horrible, lots of duds and splits.

Back from the depths of the archival file cabinet, I have finally found the reference I was seeking in this matter. Back in 1990, Rifle #132 magazine ran an article on "A forgotten Classic...7.65x53 Mauser" by Robert Gaulden. It is an interesting and enjoyable article to read describing what a great leap in technological developement this cartridge represented and how it is still a masterpiece today (in 1990 at 101 years of age).
In the article, Gaulden mentions running into the headspace problem with the "SF" 81 ammo in his 1909 Argentine rifles and concludes that there must have been two different chamberings for the 1909's and that his were chambered for the 7.65x53 and not the 7.65x54.
A few months later, in Rifle #135 (Nov-Dec 1990) a letter to the editor was posted which should prove definative on the issue.
Under the heading "7.65 Mauser Update", Capt. Luis A. Garcia Bourimborde who was at that time the Argentine Defense Attache in Tokyo, who describes himself as an Ordnance Officer, states that the only designation for military ammo that was in use during the time all the rifles were manufactured was 7.65 Mauser, with no case length designation attached, and so all rifles were made to one chamber standard, within tolerences, whether 1891, 1909 or 1935 contract. The case length denomination didn't enter into the picture until the 1950's or 60's when NATO started so designating their ammo (7.62x51), and in the case of Argentina, they simply measured their case length and applied a two digit approximation by rounding up.
Bourimborde goes on to state that he is of the opinion that the "SF" 81 ammo is likely out of spec. which he had also previously found when inspecting prior lots of Argentine manufactured ammo, but never with the old DWM, FN, HP nor Rem-UMC. He also states, "I can tell you for sure there were never two different 7.65 cartridges, only different denominations or headstamps". He also further states "Any 1891, 1909 or 1935 Argentine Mauser is safe with any military ammunition you can close the bolt on, no matter what effort is needed".
I'm not sure I wholly agree with that last statement, but I think the general meaning is correct.
I swear by Jupiter Optimus Maximus .... in the army of the consul Lucius Quinctius Cincinnatus and for 10 miles around it I will not steal anything worth more than a sestertius in any one day.
