Description

This cartridge is used in 90mm guns for training and marksmanship practice.

The projectile is ballistically matched to AP-T Cartridge M318. The body is steel with an integral bourrelet and a gilding metal rotating band. The flat base is fitted with a tracer. An aluminum windshield is threaded to the nose. A percussion primer is fitted in the cartridge base.

M353 does not contain a cartridge case liner.

M353A1 contains TiO2 liner with low temperature melt wax.

M353A2 contains TiO2 liner with high temperature melt wax.

The projectile is painted blue with white markings.

Functioning

When the weapon is fired, the burning propellant creates gases which propel the projectile out of the gun tube and ignite the tracer which burns for a minimum of three seconds of projectile flight. Since it is a practice round, the projectile lacks the penetrating capability of a service round.
