The 9×20mm Browning Long is a military centerfire pistol cartridge developed in 1903 for the FN Model 1903 adopted by Belgium, France, the Netherlands, and Sweden.[3]
Description
9mm Browning Long is similar to the 9×19mm Parabellum, but has a slightly longer casing and is semi-rimmed, so the cartridge headspaces on the rim. 9×19mm also uses a heavier bullet and is more powerful. Ammunition was produced in Belgium, France, England, Sweden[4] 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.[5]
The cartridge is now obsolete and it is 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.
As of 2016-04 Prvi Partizan in Serbia still manufactures 9mm Browning Long ammunition. The Prvi bullet weighs 7 grams (108 gr.), the diameter is listed @ 0.3585" and the velocity is listed @ 350 m/s (1148 fps). CIP lists bullet maximum @ 9.09mm (0.3578"). CIP barrel dimensions are 0.351" for minimum bore diameter, and 0.359" for minimum groove diameter.[1][6]
There is reloading data available on a few websites[7] and in some handloading manuals, e.g. the Norwegian Ladeboken.[8] Ladeboken:
- Powder: 4.5 grains N340.
- Bullet: 110 grains Norma J
- Length: 1.09 in
- Velocity: 815 ft/s (248) m/s
