The percussion cap was first invented by the Scotsman Reverend A Forsythe in 1803. His main reason for developing the system was to provide instant ignition to aid in the hunting of game birds (Forsyth was an avid duck hunter). His first percussion arm was of course a shotgun. Although patented in 1803 the percussion cap was not utilised on military arms for another 30 years.
