Totally don't know


This is a belted rimless round with nothing in the headstamp. It is about 13.3x51mm (0.53x2 inches). I need help, please.

  • Reading your cartridge dimensions I was thinking to the .56 Billinghurst-Requa cartridge [13.5X52R] but it is NOT that one because your round is belted, not rimmed. It looks like the cartridge case was polished and scratched. Could it be a shortened case??? It’s a real big puzzle … Liviu 04/21/07
