An explosive powder charge operated setting device includes a housing containing a barrel with a muzzle forming a muzzle bore at the outlet end of the barrel. Nails held in a carrier strip are fed from a magazine through a first or insertion aperture into the muzzle bore. Each nail has a head projecting outwardly from one side of the carrier strip and the nail heads have a smaller diameter than the diameter of the muzzle bore. The heads serve as stops limiting movement of the carrier strip out of the magazine. Due to the diameter difference between the nail heads and the muzzle bore, the nail heads in the stopped position do not align with the muzzle bore axis. When a nail is to be driven, it is displaced opposite to the feed direction out of the magazine into axial alignment with the muzzle bore.
