A cartridge for firearms includes a bullet connected to a casing. The casing includes a cylindrical wall that extends to an end member opposite the bullet, a hollow interior formed by the wall and the end member, means for receiving a priming composition, and means for compressing the priming composition with a firing pin engaging the end member. Propellant is placed in the hollow interior and ignited by the compressed priming composition.

1. A firing pin system for firing rimfire and centerfire cartridges in a firearm, comprising:a bolt having a passage extending between a forward end oriented toward one of a rimfire and centerfire cartridge chambered in the firearm and an opposite rearward end, said forward end defining and opening and said bolt defining a longitudinal axis aligned with a central axis of the cartridge;a striker in said passage;a first firing pin movably received in said passage forwardly of said striker; anda second firing pin movably received in said passage forwardly of said striker, wherein said first firing pin includes a forwardly oriented striking end aligned along the longitudinal axis and said second firing pin includes a forwardly oriented striking end offset from the longitudinal axis, said forwardly oriented striking ends being movable with said striker through said opening to strike a rearward end of the cartridge.2. The system of claim 1, wherein said bolt includes a stop member extending through said first and second firing pins, said stop member engaging said first and second firing pins to limit displacement of said first and second firing pins relative to said bolt.3. The system of claim 2, wherein said first and second firing pins each include an elongated slot extending therethrough for receiving said stop member.4. The system of claim 1, wherein said first and second firing pins are formed as a single unit.5. The system of claim 1, wherein said first and second firing pins are positioned in side-by-side relation in said passage.6. The system of claim 1, wherein said bolt includes a recess in said forward end thereof for receiving the rearward end of the cartridge.7. The system of claim 1, wherein said first and second firing pins each include a body portion and an intermediate portion extending between said body portion and said striking end thereof.8. The system of claim 7, wherein each of said first and second firing pins forms a lip between said intermediate portion and said body portion, said lip supporting a spring in said passage extending between said lip and an end wall of said bolt, said end wall being positioned adjacent said forward end of said bolt and said spring biasing said first and second firing pins rearwardly.9. The system of claim 1, wherein said striking end of said first firing pin includes a rounded configuration and said striking end of said second firing pin includes a flat configuration.10. The system of claim 1, wherein said striking end of said first firing pin projects forwardly of said striking end of said second firing pin.11. The system of claim 1, wherein the cartridge includes a casing having an inner wall surface extending about the central axis defining a chamber for receiving powder, and said striking end of said second firing pin is offset from said longitudinal axis by a distance that aligns said striking end of said second firing pin with the chamber of the casing adjacent the inner wall surface.12. A firing pin and cartridge system for a firearm, comprising:a cartridge including a casing extending along a central axis and having an inner wall surface spaced a first distance from said central axis, said inner wall surface extending about said central axis and defining a chamber for receiving powder, said casing including a recess for receiving a priming composition adjacent said inner surface, said recess being positioned a second distance from said central axis that is less than said first distance;a bolt having a passage extending between a forward end oriented toward the cartridge and an opposite rearward end and said passage opening at said forward end, said bolt defining a longitudinal axis aligned with said central axis of the cartridge, said bolt comprising:a striker in said passage;a first firing pin movably received in said passage forwardly of said striker, said first firing pin including a forwardly oriented striking end; anda second firing pin movably received in said passage forwardly of said striker, wherein said striking end of said first firing pin is aligned along said longitudinal axis and said striking end of said second firing pin is offset from said longitudinal axis by said second distance, said striking ends being moveable with said striker in said passage through said opening to strike a rearward end of the cartridge.13. The system of claim 12, wherein said bolt includes a stop member extending through said first and second firing pins, said stop member engaging said first and second firing pins to limit displacement of said first and second firing pins relative to said bolt.14. The system of claim 13, wherein said first and second firing pins each include an elongated slot extending therethrough for receiving said stop member.15. The system of claim 12, wherein said first and second firing pins are formed as a single unit.16. The system of claim 12, wherein said first and second firing pins are positioned in side-by-side relation in said passage.17. The system of claim 12, wherein:said first and second firing pins each include a body portion and an intermediate portion extending between said body portion and said striking end thereof; andeach of said first and second firing pins forms a lip between said intermediate portion and said body portion, said lip supporting a spring in said passage extending between said lip and an end wall of said bolt, said end wall being positioned adjacent said forward end of said bolt and said spring biasing said first and second firing pins rearwardly.18. The system of claim 12, wherein said striking end of said first firing pin includes a rounded configuration and said striking end of said second firing pin includes a flat configuration.19. The system of claim 12, wherein said striking end of said first firing pin projects forwardly of said striking end of said second firing pin.20. A firing pin system for firing rimfire and centerfire cartridges in a firearm, comprising:a bolt having a passage extending between a forward end oriented toward one of a rimfire and centerfire cartridge chambered in the firearm and an opposite rearward end, said forward end defining and opening and said bolt defining a longitudinal axis aligned with a central axis of the cartridge;a striker in said passage;a first firing pin movably received in said passage forwardly of said striker;a second firing pin movably received in said passage forwardly of said striker, wherein:said first firing pin includes a forwardly oriented striking end aligned along the longitudinal axis and said second firing pin includes a forwardly oriented striking end offset from the longitudinal axis; andsaid first and second firing pins each include a body portion and an intermediate portion extending between said body portion and said striking end thereof;each of said first and second firing pins forms a lip between said intermediate portion and said body portion, said lip supporting a spring in said passage extending between said lip and an end wall of said bolt, said end wall being positioned adjacent said forward end of said bolt and said spring biasing said first and second firing pins rearwardly.
