Guns less than 3" cals. are chambered for fixed ammunition with the powder and projectiles in brass cartridge cases. Guns from 3" cals. upwards, and including the 6" L 45 gun, can be chambered to use either fixed ammunition, or loose ammunition with the powder in cartridge bags and the projectile separate from the powder. Guns above 6" cal. and including the 6" L 45 gun are chambered for loose ammunition. The breech mechanisms of all guns up to 10" are operated by

the single motion of a hand-lever. Those of the larger guns are operated by the revolution (3 to 5 turns) of a crank.

The 8", 10" and 12" L 50 guns, and the 14" L 45 gun are for use in turrets, and are of great weight at the breech in order to balance the long muzzles, so that a comparatively small barbette may be used.
