Description
APC-T cartridge M59 is similar to cartridge M59A1 except for the primer and certain design differences in the projectile. This cartridge is assembled with percussion primer M23A1 in lieu of M38A1. The armor piercing cap is brazed, rather than crimped, to the projectile nose, and the projectile is crimped to the cartridge case by a series of equally spaced ball-point crimps rather than the circumferential crimp used in cartridge M59A1.
Hazardous Components
Primer - M23A2, 20-grain, Percussion Primer is “Standard.” Some rounds on hand may incorporate the M23A1 Primer.
