Description
9mm Browning Long is similar to 9×19mm Parabellum, but has a slightly longer casing and is semi-rimmed; the cartridge headspaces on the rim. The cartridge was developed by FN to be used in the blowback-operated FN Model 1903, a pistol designed using the same Browning patent as the Colt Model 1903 Pocket Hammerless. Using a more powerful cartridge, such as the 9×19mm Parabellum, would have required a locked-breech design. Ammunition was produced in Belgium, France, England, Sweden and the United States. There was some production in Germany during World War I for the Ottoman Empire, and the cartridge was also used in South Africa. The cartridge is now regarded as obsolete and it might be hard to find reloadable brass for this ammunition; one option handloaders have is to take the.38 Super and shorten it to the right length. Prvi Partizan in Serbia manufactures 9mm Browning Long ammunition. The Prvi full metal jacket bullet weighs 7 grams (108 gr.) with a muzzle velocity of 350 m per second. It is also currently manufactured by Mechanical and Chemical Industry Corporation of Ankara. There is reloading data available on a few websites and in some handloading manuals, e.g. the Norwegian Ladeboken. Ladeboken: • Powder: N340 • Bullet: Norma J • Length: • Velocity:
