ABSTRACT:
A high velocity driver is made with a liner between the propellant and li gas medium within a cartridge casing. This casing is reduced in length and made wider to accommodate the same desired gas and propellant volume. The liner is folded over so as to form a cylinder of propellant between a central cylinder and an annular cylinder of light gas medium. The explosive gases from the propellant thus expand the liner against the light gas medium in two directions, thereby utilizing more explosive gas energy to compress the light gas medium and thus create a higher velocity ejection of the projectile from the gun barrel.
