A projectile for a rifled firearm, comprising a hard core (1) surrounded by a continuous jacket (7) of ductile material adapted to cooperate with rifling in the firearm, said core having a nose, a head (2) of ogival shape and an integral substantially cylindrical tail (3), said core being shaped to define a shoulder (6) between said head and said tail, said jacket including a first portion (8) which overlies said nose and head of said core, said jacket including an integral second portion (12) which overlies said tail of said core, said second portion having a greater thickness than said first portion of said jacket, an outer surface of said second portion of said jacket having undulations which form circular grooves (13) at substantially right angles to the longitudinal axis of the projectile, an interior surface of said jacket adjacent said shoulder being shaped to define a free space (14) between said interior surface and said shoulder, anchoring means (9) disposed between an exterior surface of said tail and an interior surface of said second portion of said jacket for locking said jacket and core to one another so that, when said projectile is fired, said core and jacket will be propelled and rotated as a unitary body, said cylindrical tail of said core defining an interior cavity (4), and an inertia block (5) disposed within said cavity, the sizes and shapes of said cavity and inertia block being such that said inertia block substantially fills said cavity.
