7×54mm Finnish

The 7×54mm Finnish is a rifle cartridge which was designed by Lapua as a moose hunting cartridge.^[1] It was loaded by two factories, Sako and Lapua in Finland from about 1944 until 1974.^[1] It is a 6.5×55mm SE necked up to take a 7mm (.285) bullet. It may be loaded with modified 6.5×55mm SE dies drilled to fit an 8mm neck diameter. It was usually loaded with a lightweight bullet.

Dimensions were measured from a cartridge loaded by Lapua and from (if two measurements) a case that had been shot with a modified Arisaka. Because the caliber is a wildcat, those can vary greatly. The rim diameter of the 6.5×55mm is 0.480" (12.20 mm).^[2]
