The 9×20 mm Browning Long is a military centerfire pistol cartridge developed in 1903 for the 9 mm Browning pistol adopted by Belgium, France, the Netherlands, and Sweden.[2] The cartridge headspaces on the rim. Ammunition was produced in Belgium, France, England, Sweden[3] 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.[4]

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 ACP and shorten it to the right length.

There is reloading data available on a few websites[5] and in some handloading manuals, e.g. the Norwegian Ladeboken.[6]

Ladeboken:

  • Powder: 4.5 grains N340.
  • Bullet: 110 grains Norma JHP
  • Length: 1.09 in
  • Velocity: 815 ft/s (248) m/s
