The explosive properties of chemical fulminates had been identified in the 17th century but were not harnessed until the Revd Alexander Forsyth (1768-1843) combined mercury fulminate and potassium chlorate to form a priming charge capable of igniting the main charge so quickly as to make the two explosions virtually simultaneous. Forsyth developed his new primer for dispensing from a series of styles of magazine which replaced the flintlock's steel and pan; since his primer was exploded by being struck, a hammer replaced the flintlock's cock. His percussion system was patented in 1807 and is most associated with his ”˜scent-bottle’ magazine which housed about 40 primings, each of which was dispensed by simply inverting the magazine. The separate percussion cap, in which the priming was contained in the crown of a copper cap shaped like a hat, was invented c.1814 and other percussion systems, like pill, pellet, and tape primers, were developed over the following 40 years. Initially avidly accepted by sportsmen and civilians, the percussion system only ousted the flintlock for military use in the 1830s, two decades after it had been invented. Britain, France, Sweden, and the USA were the first to adopt the percussion system militarily. Percussion firearms dominated the military world from their eventual adoption until their replacement by breech-loaders in the late 1860s.
