In 1718, Puckle demonstrated his new invention, the Defence Gun, a tripod-mounted, single-barreled flintlock weapon fitted with a multishot revolving cylinder, designed for shipboard use to prevent boarding. The barrel was 3 feet (0.91 m) long with a bore of 1.25 inches (32 mm) and a pre-loaded "cylinder" which held 11 charges and could fire 63 shots in 7 minutes at a time when the standard soldier's musket could at best be loaded and fired three times per minute.[1]
