There have been a few queries on the forum regarding ammunition made by Prvi Partizan (PPU). Below is a scan of a current advertisement for PPU ammunition and components available in the UK. PPU have made other calibres, including 8x56Rmm, and offer components such as bullets, cases, and primers and also blanks. All PPU ammo that I have come across so far has had the nny headstamp including the calibre e.g. 7.62x39, 7.5x55 etc.
