A cartridge, comprising:
- a cartridge casing comprising an open mouth and an interior;
- propellant in the interior of the cartridge casing;
- and
- a bullet secured in the mouth of the cartridge casing, the bullet comprising:
- a jacket defining a cup comprising a leading edge;
- a core component seated within the cup and comprising at least one rotation inhibiting feature;
- a forward component seated in the cup forwardly of the core component and comprising at least one complementary rotation inhibiting feature that interfaces with the at least one rotation inhibiting feature, and is configured to inhibit the forward component rotating with respect to the core component;
- and
- a recess formed by the leading edge and the forward component defining a circumferential scoop.
