This is a list of firearm cartridges that have bullets in the 9 millimeters (0.35 in) to 9.99 millimeters (0.393 in) caliber range.
Case length refers to the round case length.
OAL refers to the overall length of the loaded round.
All measurements are given in millimeters, followed by the equivalent in inches between parentheses.
Ammunition or cartridge specification is usually the "cartridge maximum" specification and may not be the same as the nominally measured dimensions of production, remanufactured, or hand-loaded ammunition.
