At the "LOAD" command, or if the mount is executing "RAPID" loading: (NOTE: Rapid loading means that, when the gun fires, the gun crew immediately reloads the gun without command until "CEASE FIRE" or "CHECK FIRE" is given.) [12] Rammer Tray with Powder Case and Projectile ready for ramming. The Powder-Man: [5]: 175
The 6-inch caliber was chosen, as in many applications, for combining a relatively heavy shell with rapid hand loading. In the overall system, it was an intermediate caliber between the heavy 8-inch, 10-inch, and 12-inch weapons and the small 3-inch guns intended to defend minefields against minesweepers.
It was a breech-loading, rapid-fire cannon that was operated by a hand-crank. The barrel was four feet long and a 1.57-inch caliber. The hand crank opened the sliding breech which allowed the crew to load a round and cap the primer. As the crank was continued, it closed the breech and automatically released the hammer.
The 25-pounder was separate-loading; the shell was loaded and rammed, then the cartridge in its brass case was loaded and the breech closed. In British terminology, the 25-pounder was called "quick firing" (QF) , originally because the cartridge case provided rapid loading compared with bag charges, and was automatically released when the ...
Rapid or sustained rate of fire may be considered a weapon's absolute maximum firing rate. The term sustained refers to firing a fully-automatic weapon continuously, while rapid is limited to semi-automatic or manually operated firearms. Rapid and sustained fire are usually reserved for close-range defense against ambushes or human wave attacks ...
By the 1840s, buck and ball was issued in prepared paper cartridges that combined the projectiles with the black powder propellant charge to facilitate rapid loading of the weapon. Like any other paper cartridge, the rear of the cartridge would be torn open to expose the powder, which would be loaded, and the remaining paper, ball, and buckshot ...
The features of rifling, breech loading with fixed ammunition, and a hydraulic-spring system to absorb the gun's recoil and quickly return it to the firing position combined to improve the range, accuracy, and rate of fire of the gun compared with previous weapons, allowing it to be used more effectively in operations with infantry. These new ...
With the muzzle facing upwards, laterally rotating the trigger guard approximately 155° to the right and back deposited a ball and load of powder in the breech and cocked the gun (or wound the wheel if the gun was a wheellock). [6] [23] On some guns a small trigger had to be depressed before rotating the trigger guard.
