Abstract:

A six-month program was conducted to more conclusively determine which rifling configuration is best suited for use with high velocity medium caliber projectiles with plastic rotating bands. The program consisted of fabricating a test barrel and plastic banded projectiles and conducting test firings on five different rifling designs at -65 F, ambient temperature, and 165 F using progressively narrower rotating bands. The results showed that a sawtooth configuration and a modified conventional 18-groove design were superior to the other conventional and modified conventional designs evaluated.
