The Ferguson rifle was one of the first breech loading rifles to be widely tested by the British military. Other breech loaders were experimented with in various commands including earlier versions of the Ordnance rifle by Patrick Ferguson when he was in the Fever Islands (Caribbean). It was often misreported by historians to be a .65 (.648 true) caliber rifle. It actually used a standard British carbine ball of .615 caliber.
