yes, it is a Swiss military rifle. They are supposed to be very well made, and accurate. The 7.5 is ballistically very close to the .308 Winchester. I'm not sure of the availability of ammo, if I were you I would check places like Midway, Natchez, Midsouth... you might even check Cheaper Than Dirt... they have a lot of milsurp ammo. Old Western Scrounger will probably have it, but they are pricey....
