Explosive projectiles

An explosive projectile comprises a projectile casing, a high explosive charge filling a portion of the space inside the casing, an impervious case defining a detonation device cavity adjacent to a surface of the explosive charge, and located adjacent to the said surface of the explosive charge between the inside wall of the projectile casing and the impervious case, a pre-formed solid elastic sealant ring such that the seal effected by the sealant ring between the projectile casing and the impervious case is tightened if the pressure on the sealant ring from the material of the explosive charge increases.
