Volley gun
The Ribauldequin was a medieval version of the volley gun. It had its barrels set up in parallel. This early version was first employed during the Hundred Years' War by the army of Edward III of England, in 1339. Later on, the late Swiss army employed it.
Whitworth rifle
In 1860, the British National Rifle Association held its first annual meeting at Wimbledon. Queen Victoria fired the first shot from a Whitworth rifle on a machine rest at 400 yards, and struck the bull's-eye 1-1/4 inch from its center.
