Mm Arisaka

The 6.5x50mm Arisaka was the service cartridge for the Model 38 bolt action rifle used by the Imperial Japanese troops. Large numbers of these rifles were brought back to the United States by returning Gl's from the Pacific theater of operations following VJ Day.

The 6.5x50mm has a semi-rimmed case with the smallest powder capacity of any of the military 6.5mm cartridges. Commercial ammunition and components are available from Norma.

Norma factory ammunition produced 40,000 P.S.I. in our test barrel. These loads do not exceed that pressure.
