A bullet includes at least a mid core and a rear core in tandem alignment. The hardness of the mid core is greater than the hardness of the rear core. A jacket envelops both the mid core and the rear core. The jacket has a generally cylindrical sidewall, which is in contact with the mid core, and a boat-tail, which is in contact with the rear core. The rear core is substantially contained within the boat-tail. The mid core and the rear core may be substantially lead-free. In one embodiment, the bullet includes a front core in tandem alignment with the rear core and in contact with a nose portion of the jacket. In another embodiment, the mid core extends from the nose portion of the bullet to the boat-tail.
