I'm thinking more and more that my mauser is a 108 year old 7.65 Argentine, rather than a rebarrelled 7mm to .308. I'm not familiar with the 7.65, would it be a good rifle for my girlfriend, I wanted a little less kick than a .30-06, but more stank than a .243, how will the 7.65 compare?? I'm taking it to a smith tonight to get head spaced and checked out, but I'm betting I'm going to find out that it's an Argentine, since it is a German made Spanish Mauser. How well should it shoot?? how accurate can I expect it to be?

I have an M1909 Argentine, sounds like you have the M91, if so it will not stand up to quite as heavy a load as the 1909 version. The 7.65 is an excellent cartridge design. In a strong action, it is between a .308 Win. and a 30/06, in that it holds more powder than the .308 case and will produce equal or slightly higher velocities. TYou could load it down for your girlfriend to where it would perform like a .300 Savage. I have never slugged my barrel, but it shoots .308 diameter bullets very well. Case necks split soon, however, due to excessive sizing. Mine has a 29" barrel, and will shoot one load using IMR 4350 and Sierra 200 grain bullets into half an inch @ 100 meters (with 3-9X scope on board).
