Claim 0:
1. A shaped charge liner, comprising:
a plurality of liner segments for a shaped charge configured to perforate a sidewall of a wellbore upon detonation, wherein the plurality of liner segments comprises:
a tip liner segment comprising a first group of compacted metal powder having a hollow cone shape with a trailing interface end disposed opposite a tip end, wherein the trailing interface end has a larger diameter than the tip end, and wherein the tip liner segment is configured to be disposed in a shaped charge casing of the shaped charge; and
a base liner segment comprising a second group of compacted metal powder having a truncated hollow cone shape with a trailing base end disposed opposite a leading base interface end, wherein the trailing base end has a larger diameter than the leading base interface end, and wherein the base liner segment is configured to be disposed at least partially within the shaped charge casing,

wherein each of the plurality of liner segments has a distinct density gradient along an axial length of the liner segment, wherein each of the plurality of liner segments are stacked and pressed together to form a single continuous liner, and wherein a variation between the distinct density gradients determines a momentum gradient of the single continuous liner that thereby affects a desired jetting profile through the sidewall of the wellbore upon detonation.
