A firearm projectile includes a precision-machined outer component having a generally cylindrical body, a tip at the forward end of the body, a base at the rear end of the body, and a precision-machined cavity machined into the outer component. A precision-machined inner component is pressed into the cavity. The outer component includes a homogenous material that is softer than firearm barrel steel. The inner component includes a material having a higher density than the outer component and a higher density than an armor plate, such as solid tungsten, tungsten carbide and potential some Nanotechnology materials such as NanoSteel®. A cap may be attached to the outer component to seal the inner component inside the cavity. The cavity can be machined from the front or rear end of the outer component. The cap fits into the rear of the projectile or may be a bullet tip. The cavity and the inner component may be cylindrical or tapered.

What is claimed is: 1. A firearm projectile, comprising: a precision machined outer component, the outer component comprising a generally cylindrical body, a tip tapered from a forward end of the body, a base at a rear end of the body, and a precision-machined cavity machined into the outer compone
What is claimed is: 1. A firearm projectile, comprising: a precision machined outer component, the outer component comprising a generally cylindrical body, a tip tapered from a forward end of the body, a base at a rear end of the body, and a precision-machined cavity machined into the outer component, wherein the cavity is perfectly concentric to within 0.001 inches with the rotation axis of the outer component; and a precision-machined inner component pressed into the cavity, wherein the projectile has a single piece core, the projectile fired from a .408 cartridge capable of perforating a 1-inch WearAlloy 550 armor steel elate at 100 yards. 2. The firearm projectile of claim 1, where the outer component further comprises: a homogenous material that is softer than firearm barrel steel and strong enough to withstand the stresses of firing. 3. The firearm projectile of claim 2, where the inner component further comprises: a material having a higher density than the outer component. 4. The firearm projectile of claim 3, where the inner component further comprises a material having a higher density than an armor plate. 5. The firearm projectile of claim 3, where the inner component comprises solid tungsten. 6. The firearm projectile of claim 3, where the inner component comprises tungsten carbide. 7. The firearm projectile of claim 1, further comprising: a cap attached to the outer component to seal the inner component inside the cavity. 8. The firearm projectile of claim 1, where the cavity is machined into the base end of the outer component toward an interior of the outer component. 9. The firearm projectile of claim 1, where the cavity and the inner component each comprise a cylinder. 10. The firearm projectile of claim 1, where the cavity and the inner component comprise truncated cones. 11. An armor-penetrating firearm projectile, comprising: a precision machined outer component, the outer component comprising a generally cylindrical body, a tip tapered from a forward end of the body, a base at a rear end of the body, and a precision-machined cavity machined into the outer component, and further comprising a homogenous material that is softer than firearm barrel steel and strong enough to withstand the stresses of firing, wherein the cavity is perfectly concentric to within 0.001 inches with the rotation axis of the outer component; and a precision-machined inner component pressed into the cavity, the inner component comprising a material having a higher density than the outer component and a higher density than a targeted armor plate, wherein the projectile has a single piece core the projectile fired from a .408 cartridge capable of perforating a 1-inch WearAlloy 550 armor steel plate at 100 yards. 12. The firearm projectile of claim 11, further comprising: a cap attached to the cavity in the outer component to seal the inner component inside the cavity. 13. The firearm projectile of claim 11, where the inner component comprises tungsten. 14. The firearm projectile of claim 11, where the cavity and the inner component each comprise a cylinder. 15. An armor-penetrating firearm projectile, comprising: a precision machined homogenous solid metal outer component having a body and a tip; a precision machined cavity in the body, wherein the cavity is perfectly concentric to within 0.001 inches with the rotation axis of the outer component; an inner component having a shape that matched the cavity; a cap fitting into an end of the body, wherein the design of the outer component, inner component and cap ensure gyroscopic stability of the projectile during flight, wherein the projectile has a single piece core the projectile fired from a .408 cartridge capable of perforating a 1-inch WearAlloy 550 armor steel plate at 100 yards. 16. The firearm projectile of claim 15, where the outer component further comprises: a homogenous material that is softer than firearm barrel steel and strong enough to withstand the stresses of firing. 17. The firearm projectile of claim 16, where the inner component further comprises: a material having a higher density than the outer component. 18. The firearm projectile of claim 17, where the inner component further comprises a material having a higher density than an armor plate. 19. The firearm projectile of claim 15, wherein the projectile has less than two minute of angle accuracy at 1000 yards. 20. The firearm projectile of claim 15, where the projectile has one minute of angle accuracy at 300 yards.
