This cartridge is composed of a steel projectile filled with 4.06 pounds of white phosphorus. The nose of the projectile is fitted with a steel adapter which performs two major functions: it provides a surface for sealing the filler cavity by press fit of burster casing M5, and it provides a fuze well for assembly of the PD fuze. Burster charge M5, which contains 3.6 ounces of tetrytol is assembled in burster casing M5. The projectile has a pre-engraved gilding metal rotating band near the base and two indexing buttons on the forward bourrelet. The projectile is crimped to a perforated steel cartridge case. The cartridge case contains a plastic and rayon liner and a press-fitted percussion primer.
