The M338A1 cartridge is for use against ground targets, primarily armored materiel.
The body of the projectile, which is a hardened steel monobloc shot, has a flat nose. An aluminum or steel windshield is welded onto the forward end of the shot body. The projectile base is threaded to receive tracer M5A2B1, which contains an igniter composition and red tracer material. The base of the tracer is protected by a moisture proof seal. The projectile is assembled to the cartridge case (M18 series) by stab crimping.
The M338 cartridge is exactly the same as cartridge M338A1 except for some minor variations in metal parts.
