You have a 91/41 which was the standard rifle used in WW2. It was made by Armaguerra Cremona which produced about 250,000 between 42-44.
Don't bother getting the PRVI ammo for it if you want to be accurate, these rifles are actually .268, not .264 like other 6.5s. You will get frustrated like everyone else that bought a Carcano, got the PRVI ammo, shot it, didn't hit anything, called it a piece of crap rifle, and finally sold it on the EE. The rifle only works well with the same type of bullet it was made for.
Once I started handloading .268s made only by Hornady (and damn $$$) I got some very good accuracy in my Carcanos.
The proper bullet has so much surface area (long with no boat tail) that the rifling really gives it a good spin in the barrel, and thus it has a flat trajectory, excellent accuracy at shorter ranges, and unbelievable penetration. Too much penetration actually. The bullet does not tumble and cause damage the way bullets should. But rather goes clean through creating neat wounds and less cavitation. British doctors would comment on these Italian "non lethal" rifle wounds in North Africa. And in 1963 Dallas, Texas the bullet went through two people and lots of bone - and emerged intact. The magic bullet is not magical at all.
