The 7.65x53 is a great cartridge and if the U.S. Ordinance Corps had been the least bit forward looking, they would have selected it, or a 7.62mm bore version of it, instead of the 30-40 Krag in 1892.
In a strong action, not the 1891 Argentine Mausers made in Germany by Ludwig Lowe and DWM, the 7.65x53 is equivalent to the 7.62x51 in performance potential. I had a minty 1909 carbine for awhile, shot a box of 2 of Norma factory loads, but the straight grip stock ergs didn't work for me, so I sold it to a collector for a fraction of what it would bring today.
