Question about cartridge

Hello! I’m new here ! Can you please help me to ID this cartridge. Thank you ! Head stamp is 05 86

I am sure someone can. Being pretty much a freshman here myself, I know that some measurements of the
cartridge would help. Diameter of the ‘bullet’, case lenght, total lenght (COL) as a minimum.

Lancaster is correct in pointing out the importance of careful measurements for identification.
But this very characteristic cartridge is easily recognizable.
It is an East-German blank (Platzpatrone M43) for the 7.62 mm Kalashnikov assault rifle.
05 is the maker “Spreewerk Lübben” and 86 the year of manufacture.

Please post future cartridge identification requests in the “General Ammunition Discussion”.
