Base separation of cast explosives in projectiles is prevented by means of a resilient device, such as a spring washer, positioned between the bottom of the fuzewell cavity in the cast explosive and the bottom of the fuzewell liner threadedly secured to the projectile. By tightening the liner, the spring washer is compressed, causing it to apply a force upward on the liner and downward on the cast explosive toward the base of the projectile, thereby allowing the cast explosive to move in response to thermal changes while maintaining it in contact with the projectile base at all times.

A projectile comprising in combination: a metal casing having a closed base end and a forward end having a threaded central opening; a cast explosive charge filling said casing, said charge having a longitudinal cylindrical cavity at its forward end to receive a fuzewell liner for containing a fuze for detonating said charge, a fuzewell liner positioned in said cavity and threadedly secured to said casing at said threaded opening; and a resilient means compressed between the bottom of said cavity and the bottom of said liner, wherein said compressed resilient means presses against said liner and said cast explosive with a force sufficient to prevent or greatly minimize separation of said cast explosive from the base end of said casing in response to thermal contraction or expansion of said cast.
