The ram gang loads the  shell, whilst a separate powder crew stands by to go to the rear of the breech after the shell has been rammed home into the forcing cone. Unlike the 12-inch BCLR (Barbette Carriage Long Range) guns of Batteries Smith and Hearn, there is insufficient space to maneuver both shell and powder

At the rear of the ram, there is insufficient room to push, so they are facing the rear and utilizing a reverse pull motion.

Guns of this size can be fired manually (by lanyard) or by an electrical firing switch. The live wire can be easily seen along the gun's side running to the breech's electrical firing mechanism. .
