The disc is frangible upon the projectile striking a solid or semi-solid target. Preferably the core is likewise frangible. In one embodiment the disc is incorporated into the ogive of a projectile. In another embodiment, a disc may be incorporated into a projectile comprising multiple cores, the disc being disposed between adjacent surfaces of the cores.
