9X57mmMauser (Rimless)
European Sporting Cartridges
The 9mm or 9X57mm Mauser (Rimless) was introduced in 1881, as a necked up version on the
8x57mm Mauser to 9mm.
It was popular all over  the world, including the USA.
It was loaded in the USA until app. 1939, and Remington and Winchester made Rifles for that time.
It is now obsolete in the USA and I beleive in Europe(?).
These boxes were taken from a Factory Bricks of 10 Boxes.
