A determination was made of the suitability of the electromagnetic- pulse metal-forming process for the attachment of copper rotating bands to 40mm projectiles to find cheaper and faster method than previously used. Static and firing tests gave satisfactory results. It was concluded that the process can also be developed for use on ammunition of other calibers. An aluminum 40mm proof projectile was modified to permit use of this process, and modified rounds are now being produced. Modified steel projectile bodies are also being made and successfully used for testing of fuzes. The modified design is intended for final production.
