I have been offered for sale some unidentifiable 7.9x57 ammo from Norway when I was buying some nazi ammo. The case is green like that of the low velocity k98k suppressor ammo and appears to have a normal Spitzer projectile. The seller describes them as “raufoss” and “kongsberg”. He sent several pictures but I wasn’t able to see a headstamp, I have included a pic of what they look like and hope one of you can shed some light on what they might be.
I don’t believe he meant they were made in raufoss norway when he described them as they needed a separate export permit but apparently he can’t own explosive/spotter/incendiary cartridges.
