The invention discloses a shell-free bullet with a hollow bullet body and a launching
gun barrel thereof. The shell-free bullet is composed of three main parts of the hollow bullet body, an
artillery primer and
propellant powder. The
propellant powder has dampproof and loss prevention functions. The temperature of a chamber is low at the time of shooting, so that a cook-
off phenomenon does not occur to the bullet. The shell-free bullet is launched by an exhaust
rifling gun barrel and a blasting wing smoothbore
barrel, the firing range is far, precision is high, and the killing ability is large. The shell-free bullet is small in volume, light in weight, concise and attractive, firm and reliable, and easy to manufacture, and the material is saved. Based on the shell-free bullet with the hollow bullet body and the launching
gun barrel thereof, conventional firearm parts such as bullet supplying parts, locking parts, automatic parts, percussion parts, safety parts, aiming parts, holding parts and food frame parts are combined to constitute various large, middle and
small caliber series of bullet firearms such as rifles,
machine guns, handguns and submachine guns, so that different
battlefield effects are given play, different fighting tasks are finished, and the shortcomings of a G11 shell-free bullet gun and a traditional bullet are overcome.
