Can anyone identify this for me please?
The only hit I got on the head stamp was for a Czech made (Zbrojovka Brno) 7.92mm BESA round but the projectile dimension (ø7.10mm at the neck) doesn’t match.
Case length is 56.75mm and tapers from 11.85mm at the base to 10.68mm at the shoulder. The neck diameter is 8.07mm. The head is 11.95mm. The overall length of the round is 77.75mm
This picture shows it next to a 7.92 Mauser round.
Is this a 7x57 Mauser?
