Ammo question please. I have been purchasing 6.5x55mm SWEDISH for my Swedish Mauser and 7.7x58mm JAP for my Arisaka. Is 6.5x55mm the same as 6.5x55mm SWEDISH? And is 7.7x58mm the same as 7.7x58mm JAP? Must the shell or box be designated Swedish or Jap? Is it the ammo the same with or without the Swedish or Jap designation.
Thanks
