US Cartridge, 90mm APERS, XM590
Canister Cartridge XM590 is an antipersonnel round designed specifically for close-in firing.
This cartridge consists of a cartridge case crimped to an unfuzed aluminum projectile containing a payload of low-drag, fin-stabilized steel-wire fragments called flechettes. The projectile can be identified by the wedge shaped indentation in the plastic nose block capping the aluminum cylinder. This design facilitates break up in flight. The heavy aluminum base of the projectile is perforated with three bleed holes, each 3/16 of an inch in diameter. A perforated primer tube containing the percussion primer is assembled to the projectile base.
