These guns fire from a 5-round ammunition clip and have a very quick reload, so their cyclic rate of fire and effective rate of fire are practically identical. They cannot jam.

 The Mark VII mount is a single mount that uses a British-produced Bofors gun. It was operated by two crewmen, a gunner and a loader. Sitting on the left side of the gun, the gunner trained and elevated the gun, which was hydraulically driven and had elevation limits of -10°/+90°. He was also in charge of firing it. The loader, who stood on a platform just behind the gunner, was, of course, tasked with the loading of ammunition into the gun.
-SAP, AP, and HE rounds were produced for the British Bofors guns, each weighing 0.894 kg (1.97 lbs.). Both SAP and AP were painted black with white tips, with AP being distinguished by a white ring painted on the body. HE, painted buff, had 0.068 kg (0.15 lbs.) of TNT and self-destroyed after travelling for approximately 3200 m (3500 yds.) Rounds with tracer were indicated by an additional red ring. At the right of the gun was a ready-use ammunition rack with a capacity for six clips each. Ammunition was loaded by the crew through the top of the gun into an ammunition "hopper", from which the automatic loader pulled the ammunition from. Spent cartridges were ejected out of the rear of the gun, down chutes redirecting them under the guns towards the front where they can be ejected safely away from the crew. Altogether, the Mark VII single mount weighed 1.42 tonnes.

Altogether, the Mark VII single mount weighed 1.42 tonnes.
 The Mark VII single mount was introduced very late into the war, around May 1945. The Royal Navy estimated that the Bofors gun was about as effective against kamikaze aircraft as their domestic design, the Vickers 2-pdr Pom-Poms, but they found that the Bofors gun was about twice as effective against bombers. After WWII, the Mark VII mount gradually replaced the older, hand-cranked Mark III single mount, seeing use on many Royal Navy ships, as well as some limited usage by the Royal Australian Navy, as late as the 1970s. It's a testament to the gun's effectiveness as an anti-aircraft weapon that it remained in service for so long, hindered only by the arrival of the jet age.
