So I went to a gun show over the weekend and picked up some 8mm Mauser surplus ammo, but have no idea where it was made. The round is marked 7.9/FS/1947/TOC. The "O" is actually some symbol or letter I can't replicate easily on the computer, sort of like an O with some flames on top. I understand 7.9 mean 7.92x57, and 1947 is the year of manufacture so it's corrosive, but can anyone tell me anything else about this particular ammunition? Thanks in advace.
