Home Forums Hunting & Shooting Long Range Hunting Army Tests Bullet With Dimples

After testing a series of prototypes, the Aberdeen bullet design team settled on a copper-jacketed bullet with dimples about 0.5 mm in diameter. The first-generation bullets were formed in special binary impact swages that press-form the dimples after the bullets were pointed up in conventional dies. Future production bullets will be made with an advanced metal-injection-molding (MIM) process that forms the dimples directly into the surface of the bullets. Rather than simply wrap the core material (which is classified), the MIM is molecularly bonded to the core. The Aberdeen LRPP team calls this �Exo-Jacket� construction, as in �Exo-Skeleton�.
