6.5x50 JAP Ammo

The 6.5×50 Japanese Arisaka, 6.5mm Japanese Arisaka, 6.5 Jap, or 6.5x50mmSR Arisaka is a semi-rimmed cartridge, with a 6.5mm (.264) diameter bullet. Historically it has been referred to as the "6.5 Jap". The 6.5x50 Japanese Arisaka naming convention follows common European naming conventions. The first part of the cartridge's name refers to the diameter of the bullet (6.5mm or .264 inches) followed by the case length in millimeters. It was adopted by the Imperial Japanese Army in 1897, along with the Type 30 Arisaka infantry rifle and carbine. The new rifle and cartridge replaced the 8×52mm Murata round used in the Type 22 Murata Rifle. In 1902, the Imperial Japanese Navy chambered its Type 35 rifle for the cartridge as well. In 1905, the round also came to be offered in the Type 38 Arisaka infantry rifle and carbine, both of which rendered the Type 30 obsolete in imperial army service. Type 44 cavalry carbines, first adopted in 1911, were also chambered in 6.5×50mm.
