6.5x50SR Arisaka

6.5x50SR Arisaka

This cartridge was first issued in 1897 along with Arisaka Type 30 rifle, and became the standard ammunition for Japanese armed forces until the end of WW2. Original version of this round was loaded with round-nose bullet, which was later changed to more modern pointed bullet with introduction of the Type 38 Arisaka rifle and Type 38 6.5mm cartridges. It was used in a number of Japanese bolt-action rifles and machine guns. After the WW2, many weapons of ex-japanese origin remained in use in SE-Asia region for a significant period. No modern firearms are produced for this ammunition, and production of this round is all but gone (few ammunition manufacturers still make modern versions of this round for those people who still own old weapons).
