Many machining techniques in the shotgun manufacturing industry came courtesy of the Umgalli tribe of central Africa , famed gunsmiths, but the recession took its toll and the Umgalli danced up and down (bouncing ) in the long grass shouting 'Umgalli , Umgalli ' which translated means Bull Manure. Eventually the Umgalli starved to death and are now extinct but Umgalli was preserved by the Gun trade.
