A firearm projectile comprising: a jacket comprising a first piece and a second piece removably coupled to the first piece, wherein the jacket defines a front side on the second piece, a rear side on the first piece, an internal cavity and an opening in the front side of the second piece contiguo

1. A firearm projectile comprising: a jacket comprising a first piece and a second piece removably coupled to the first piece, wherein the jacket defines a front side on the second piece, a rear side on the first piece, an internal cavity and an opening in the front side of the second piece contiguous with the internal cavity;a detonator positioned in the internal cavity defined by the jacket;a striker having a first end and a second end, wherein the striker is positioned partially inside the internal cavity defined by the jacket, with the striker passing through the opening on the front side with the first end positioned outside of the internal cavity and with the second end positioned near the detonator inside of the internal cavity, wherein the striker is constructed and arranged to detonate the detonator when the striker impacts a target with sufficient force, and wherein the striker is constructed and arranged to compress the detonator between the second end of the striker and the rear side of the jacket; anda main charge positioned within the internal cavity defined by the jacket, wherein the main charge and the jacket define an air-filled chamber located between the front side of the jacket and the main charge, wherein the striker extends into the main charge. 2. The projectile of claim 1, wherein the air-filled chamber defined by the main charge is constructed and arranged to focus the blast energy of the main charge toward the front side of the projectile. 3. The projectile of claim 2, wherein the main charge defines a substantially conical surface against the air-filled chamber. 4. The projectile of claim 1, further comprising a non-explosive liner abutting the main charge in the air-filled chamber. 5. The projectile of claim 4, where the non-explosive liner is constructed from a ductile metal. 6. The projectile of claim 1, further comprising: a booster charge positioned near the main charge and near the detonator in the internal cavity defined by the jacket. 7. The projectile of claim 1, wherein the first end of the striker is larger than the opening on the front side of the second piece of the jacket such that the first end cannot pass through the opening without either the first end or the opening deforming. 8. The projectile of claim 7, wherein the jacket and the striker cooperatively form a delayed arming mechanism that prevents the striker from detonating the detonator when the projectile is initially fired, wherein the jacket and the striker are constructed and arranged such that, when the projectile is fired, the striker accelerates with the projectile without the jacket or the striker deforming sufficiently for the first end to pass through the opening in the jacket. 9. The projectile of claim 1 wherein a frustoconical portion of the striker defines a frustoconical outer surface. 10. The projectile of claim 9, wherein the frustoconical portion of the striker and the main charge cooperatively form a safety that prevents the striker from detonating the detonator unless the striker impacts a surface that imparts sufficient force to the striker such that the frustoconical portion deforms the main charge and moves relative to the main charge thereby permitting the striker to impact and detonate the detonator. 11. The projectile of claim 9, wherein the frustoconical portion of the striker, the main charge and the jacket cooperatively form a safety that prevents the striker from detonating the detonator unless the striker impacts a solid surface with sufficient force to deform the main charge and the jacket to permit the frustoconical portion of the striker to move relative to the main charge for the striker to impact and detonate the detonator. 12. The projectile of claim 1, wherein the detonator is positioned near the rear side of the jacket. 13. The projectile of claim 1, wherein the first end of the striker defines a finned portion constructed and arranged to minimize the volume occupied by the first end in the air-filled chamber while maintaining sufficient rigidity to not significantly deform on the initial impact when the striker impacts a solid surface. 14. A shotgun shell assembly comprising: the projectile of claim 1;a shotgun shell; anda propellant charge. 15. The shotgun shell assembly of claim 14, further comprising: a sabot that surrounds the projectile in the shotgun shell. 16. The shotgun shell assembly of claim 14, wherein the shotgun shell is 12-gauge. 17. A firearm cartridge comprising: the projectile of claim 1;a case; anda propellant charge, wherein the case and the projectile cooperate to contain the propellant charge. 18. A shotgun shell assembly comprising: a firearm projectile comprising: a jacket comprising a first piece and a second piece removably coupled to the first piece, wherein the jacket defines a front side on the second piece, a rear side on the first piece, an internal cavity and an opening in the front side of the second piece contiguous with the internal cavity;a detonator positioned in the internal cavity defined by the jacket;a striker having a first end and a second end, wherein the striker is positioned partially inside the internal cavity defined by the jacket, with the striker passing through the opening on the front side with the first end positioned outside of the internal cavity and with the second end positioned near the detonator inside of the internal cavity, wherein the striker is constructed and arranged to detonate the detonator when the striker impacts a target with sufficient force; anda main charge positioned within the internal cavity defined by the jacket, wherein the main charge and the jacket define an air-filled chamber located between the front side of the jacket and the main charge, wherein the striker extends into the main charge;a shotgun shell; anda propellant charge. 19. The shotgun shell assembly of claim 18, further comprising: a sabot that surrounds the projectile in the shotgun shell. 20. The shotgun shell assembly of claim 18, wherein the shotgun shell is 12-gauge. 21. A firearm cartridge comprising: a firearm projectile comprising: a jacket comprising a first piece and a second piece removably coupled to the first piece, wherein the jacket defines a front side on the second piece, a rear side on the first piece, an internal cavity and an opening in the front side of the second piece contiguous with the internal cavity;a detonator positioned in the internal cavity defined by the jacket;a striker having a first end and a second end, wherein the striker is positioned partially inside the internal cavity defined by the jacket, with the striker passing through the opening on the front side with the first end positioned outside of the internal cavity and with the second end positioned near the detonator inside of the internal cavity, wherein the striker is constructed and arranged to detonate the detonator when the striker impacts a target with sufficient force; anda main charge positioned within the internal cavity defined by the jacket, wherein the main charge and the jacket define an air-filled chamber located between the front side of the jacket and the main charge, wherein the striker extends into the main charge;a case; anda propellant charge, wherein the case and the projectile cooperate to contain the propellant charge.
