EXAMINATION OF ROTATING BANDS FROM 155MM PROJECTILE, HE, M107, FIRED WITH PROPELLANT CHARGE XM119

Abstract

This study was conducted to determine the adequacy of the rotating band, particularly band retention, of the standard 155mm M107 shell when fired with propelling charge XM119 from the 155mm Howitzer Self-Propelled M109 (T196E1). Rotating bands from sixteen recovered M107 shell were examined. The bands imparted full spin to the projectile, but showed varying amounts of wear proportional to the pressure and velocity level. This amount of wear did not adversely affect the velocity or range dispersions. Band fly off was primarily attributed to poor banding practice and lack of band seat undercuts. If the percentage of bands fly off warrants rebanding, widening of the band seat and inclusion of 15 degree band seat undercut is recommended.
