Description
Original Item: Rudyard Kipling gave the name Screw Gun to the British Ordnance RML 2.5-Inch Mountain Gun in his famous poem Screw Guns, and the gun has been known thus ever since. The Ordnance RML 2.5-Inch Mountain Gun was made with the barrel in two parts so that it could be broken down into loads that could be carried by animal transport, usually mules but occasionally camels. The two sections of the gun were connected by a threaded, or screwed, joint.
RML stands for Rifled Muzzle Loading; that is, powder and projectile were loaded from the muzzle, while the rifling consisted of three spiral grooves. Studs on the exterior of the projectile fitted into the grooves to impart spin. Studded shells of a wide range of calibers were used by the Army and Navy of the U.K. and are a very significant stage in artillery development. Although the studs on our 2.5-inch screw gun shells are zinc, zinc had been replaced by copper in calibers used by the Royal Army and Royal Navy, and most surviving studded shells have copper studs.
