In 1718, James Puckle of London, England, demonstrated his new invention, the "Puckle Gun," a tripod-mounted, single-barreled flintlock gun fitted with a multishot revolving cylinder. This weapon fired nine shots per minute at a time when the standard soldier's musket could be loaded and fired but three times per minute. Puckle demonstrated two versions of the basic design. One weapon, intended for use against Christian enemies, fired conventional round bullets, while the second variant, designed to be used against the Muslim Turks, fired square bullets, which were believed to cause more severe and painful wounds than spherical projectiles. The "Puckle Gun" failed to attract investors and never achieved mass production or sales to the British armed forces. One newspaper of the period observed following the business venture's failure that "those are only wounded who hold shares therein."

It was intended for shipboard use to prevent boarding. The barrel was 3 feet (0.91 m) long with a bore of 1.25 inches (32 mm). It had a pre-loaded cylinder which held 11 charges and could fire 63 shots in seven minutes—this at a time when the standard soldier's musket could at best be loaded and fired three times per minute.
