7.7x58mm Arisaka

The 7.7x58mm Arisaka cartridge or Type 99 rimless 7.7 mm was chambered in the World War II Arisaka Type 99 Rifle. The cartridge was designed to replace the aging 6.5 mm Arisaka cartridge after seeing the .303 British in action in China. Due to lack of materials the plan to phase out the 6.5 mm Arisaka cartridge by the end of the war wasn't completed.

While the round chambered by the Arisaka rifle used a rimless case, rimmed and semi-rimmed variants were produced for use in some Japanese machine guns. The 7.7 mm Arisaka uses the same .311-.312" bullets as the .303 British, and its cartridge case is similar in power to the .30-06 Springfield(7.62x63mm). Factory loaded ammunition and brass cases are available from Norma and Graf; Hornady, Sierra and Speer also produce usable bullets.
