Springtime for T110 and the Americas

The_Chieftain: As an interim stop to control rotating band failures, the design of the basic T116E5 projectile was changed to include a wider band and a band seat 0.125 inch deeper. The modified projectile was designated the T116E6. With respect to body engraving,it was noted that shot with rubber obturator had been fired without any evidence of engraving. It was felt, therefore that this type of device should be investigated further. Consequently, the inclusion of such an obturator in the design of the T116E6 shot resulted in its being redesignated the T116E7.
