Abstract
An improved gun barrel is disclosed in which the breech chamber has a length (B) and diameter (D.sub.2) which are chosen relative to the axial spacing (a) between a forward guiding ring (8) and a rearward driving band (6) of the ammunition unit to be fired from the barrel and relative to the diameters (d.sub.1 and d.sub.2) of the guiding ring and driving band, so that the longitudinal axis of the ammunition unit and the bore of the barrel are substantially aligned before the forward guiding ring enters the rifled portion of the bore.
