Abstract
An axisymmetric disk-shaped cartridge is provided for firing from a gun having a fluted bore. The cartridge is initiated by a firing pin and includes a primer core, a propellant charge, a booster charge, a projectile mass, an ablative cap and a ductile metal coating. The projectile mass is disposed over the booster charge while the ablative cap is disposed over the projectile mass. The coating and mass elongate and radially narrow to maintain axial symmetry while being accelerated along the bore.
