6.5x50 Japanese Ammo

Intended Use

Originally designed for use in military bolt-action rifles, particularly the Type 38 Arisaka, the 6.5x50mm was intended for infantry combat. Today, this cartridge is primarily used for target shooting, collecting, and historical reenactments. Though less common, it can also be used for hunting small to medium game when loaded with expanding projectiles.

Caliber/Size

The 6.5x50mm Japanese fires a 6.5mm (.264 inch) diameter bullet, typically weighing between 139 and 140 grains. It features a rimless, bottlenecked case that offers solid feeding reliability in bolt-action systems. The caliber’s design balances manageable recoil with decent ballistic performance.

Performance Characteristics

With typical muzzle velocities between 2,400 and 2,500 feet per second, the 6.5x50mm delivers moderate energy and a relatively flat trajectory for its time. While not as powerful as modern 6.5mm cartridges like the 6.5 Creedmoor, it still offers respectable accuracy and terminal performance within 300 yards. Recoil is notably mild, making it easy to shoot even in full-length military rifles.

Material / Construction

6.5x50mm Japanese ammunition is usually produced with brass cases and features full metal jacket (FMJ) bullets for historical authenticity. Soft point (SP) variants may also be available for those who intend to hunt with this caliber. Due to its rarity, many shooters choose to reload using Boxer-primed brass and appropriate 6.5mm bullets.

Brands and Manufacturers

Due to its niche market, 6.5x50mm Japanese ammunition is produced in limited quantities. PPU (Prvi Partizan) is one of the most reliable current sources for factory-loaded ammo. Specialty and custom ammunition makers occasionally produce runs for military surplus rifles, and reloading components are still available from brands like Hornady and Norma.

Brief History of the Caliber

Developed in 1897, the 6.5x50mm Japanese served as the standard rifle cartridge of the Imperial Japanese military through both World Wars. It was chambered in the Type 30 and Type 38 Arisaka rifles, and later used in some light machine guns. Though eventually replaced by the more powerful 7.7x58mm Japanese in later war years, the 6.5x50mm is remembered for its accuracy and reliability. It holds historical significance for collectors and is an essential part of any military surplus enthusiast’s knowledge base.
