9x20 Browning Long

The 9×20 Browning long is similar to 9×19 Parabellum but with a longer case and is semi-rimmed. The cartridge headspaces on the rim and was developed by FN to be used in their Model 1903 which is a scaled up version of the Colt 1903. The cartridge is since obsolete but can still be reloaded with .38 Super Brass.
