Nope im just history buff, with wikipedia at my fingertips
Speaking of wikipedia, here is what it says....
The carronade was a short smoothbore, cast iron cannon, developed for the Royal Navy by the Carron Company, an ironworks in Falkirk, Scotland, UK. It was used from the 1770s to the 1850s. Its main function was to serve as a powerful, short-range anti-ship and anti-crew weapon. While considered very successful early on, carronades eventually disappeared as long-range naval artillery led to fewer and fewer close-range engagements.
The carronade was designed as a short-range naval weapon with a low muzzle velocity. Its invention is variously ascribed to Lieutenant General Robert Melville in 1759, or to Charles Gascoigne, manager of the Carron Company from 1769 to 1779.
