there was a very rare 10,75x60R in the class of the 10,75x63 and a 10,75x65R in the class of the 10,75x68 Mauser. the .425 dia. indicate the german 10,75 caliber but this case i have the 12,58mm base you only find with the 10,75x68 mauser and not the 11.9mm like 9,3x74R. believe the 444 marlin is also in the smaller dia.
when the marlin case fits the chamber it could be a 11,15x60R or 11,15x65R. this was a low pressure blackpowder round develop from 36 ga. brass.
you have to give all chamber dimensions
