rifles. It's simply 6.5x55SE with 7mm (.285) bullet. It may be loaded with modified 6.5x55SE dies drilled to fit 8mm neck diameter. It was usually loaded with a lightweighted bullet.

Dimensions were measured from a cartridge loaded by Lapua and from (if two measurements) a shell that had been shot with an modified Arisaka. Because caliber is a wildcat, those can vary greatly.

7x54 MAS

In 1948, the gunsmith M. Jean Fournier sold some hunting rifles based on the MAS-36 rifle and the 7.5x54mm cartridge Mod 1929.
As the French public could not use military cartridges, it was made possible in this case by reducing the caliber to 7mm, keeping the rest the same.

Should not to be confused with the 7x54 Finnish, naming similar but cartiges are not compatible.
