The United Kingdom only deployed this gun for coast defence, and soon discarded it in favour of the similar QF 3-pounder Hotchkiss gun for both coast defence and naval use.
Ammunition was in "fixed rounds" : the projectile and brass cartridge case were loaded as a single unit. The gun used the same ammunition as the similar QF 3-pounder Hotchkiss, with either Nordenfelt or Hotchkiss fuzes. When introduced in the 1880s the propellant used was gunpowder, in British service Cordite Mark I was used as propellant from the mid-1890s onwards.
