MIL-HDBK-756 Manufacture Of Projectiles, Projectile Components, And Cartridge Cases For Artillery, Tank Main Armament, And MotorsThis expanded revision of AMCP 706-249 covers aspects relating to production of munitions that the design engineer must consider early in the development stage of the life cycle. Each munition type cited represents different disciplines with regard to design, materials, manufacturing methodology, and end use. The descriptions of acceptable manufacturing processes for manufacturing the current generation of projectiles and cartridge cases are based on state of the art and recognize current trends aimed at reducing production costs and meeting higher standards of product reliability.
