This projectile bears some resemblance to the Harding series, but may be intended for use in a smoothbore, it is an armor puncher.  The copper band in the approximate center of the body apparently is designed to trap the gas flowing up over the tapered end and expand.   If for smooth bore use it is primarily a bearing surface.
