摘要

The round of ammunition is for a hand firearm such as a rifle, pistol, machine-gun etc., with a tapering barrel. The bullet consists of a core (2), enclosed with the propellant charge (3) in a common casing (1). The charge chamber is open at the rear end, the charge being pressed into it, and the igniting cap (4) is inserted in the charge. The casing can be arranged to taper steadily at the forward end of the charge, while its rear part (1b) is thin-walled. The barrel can have axial grooves starting at the tapering portion, so as to form guide ribs in the casing.
