I picked this up at the ECRA meeting at Bisley last Sunday. I assume that it’s a blank based on the 30-06 cartridge. The headstamp reads ‘AMA’ at 12 o’clock and ‘62’ at 6 o’clock. So, it’s Danish, the primer is struck and the case is brass.
Does anyone know what it was used for and what the rings around the case signify?
Happy collecting, Peter
