|The 6.5x50mm Japanese was introduced in 1897. based on the 6.5mm Mauser & Mannlicher
cartridges and was used by the Japanese Military in the Model 38 Japanese bolt-action rifle
until the end of World War II. It has a "Semi-Rimmed" Case and is a short cartridge compared
to most 6.5mm diameter Military cartridges. Many Japanese Model 38 in 6.5x50mm were brought back into
the USA after World War II and some rifles were re-chambered to other calibers, due to the shortage of
ammunition, so make sure your rifle is truly chambered in 6.5x50mm Japanese before buying ammunition.
