Patent ID: 8869703

Claim:
An armor penetrating round, comprising: an elongated core portion defining a front end, an aft end, and a central cavity which extends from the aft end toward the front end, the central cavity having (i) an aft cross-sectional diameter adjacent the aft end and (ii) a front cross sectional diameter adjacent the front end, the aft cross sectional diameter being larger than the front cross sectional diameter; a slug portion which is disposed within the central cavity adjacent the aft end; and an outer jacket which extends around the elongated core portion to operate as an interface between the armor penetrating round and a gun barrel when the armor penetrating round is fired through the gun barrel; wherein the slug portion includes powder which is compressed to at least 60% of the crystalline density of the powder; and wherein the central cavity defined by the elongated core portion is configured to accelerate material of the slug portion, upon impact of the armor penetrating round with a target, to a velocity which is at least twice a velocity of the armor penetrating round prior to impact of the armor penetrating round with the target.
