Abstract

The present invention includes a modular cartridge system for firearms. The system includes a plurality of cartridges that each having a base, a rim, a case, and a projectile coupled to the case. Each cartridge of the system includes base and rim dimensions that are functionally equivalent to each other, projectile diameters that are variable between 0.220 inches and 0.4050 inches, and case lengths that are variable between 0.500 inches and 2.000 inches.

Claims

1. A modular cartridge system for projectile launching devices, the system comprising:

a plurality of cartridges each having a base, a rim, a case, and a projectile at least partially seated within the case;

wherein the base diameter of each cartridge is between 0.4140 inches and 0.4310 inches;

wherein the diameter of the projectile is between 0.220 inches and 0.4050 inches; and

wherein the length of the case is less than or equal to 2.000 inches.

2. The modular cartridge system of claim 1, wherein the case length is between 0.500 inches and 1.400 inches.

3. The modular cartridge system of claim 1, wherein the case length is between 1.400 inches and 2.000 inches.

4. The modular cartridge system of claim 1, wherein the cartridge case comprises a substantially cylindrical first portion having a first diameter, a substantially cylindrical second portion having a second diameter, the second diameter being smaller than the first diameter, and a conical portion intermediate the first and second portions, wherein the projectile is seated within the second portion of the case.

5. The modular cartridge system of claim 4, wherein the plurality of cartridges include a rebated rim.

6. The modular cartridge system of claim 1, wherein the case diameter is substantially constant along the length of the case.

7. A modular cartridge system for projectile launching devices, the system comprising:

a plurality of cartridges each having a base, a rim, a case, and a projectile at least partially seated within the case;

wherein the base diameter of each cartridge is between 0.380 inches and 0.400 inches;

wherein the diameter of the projectile is between 0.220 inches and 0.380 inches; and

wherein the length of the case is less than or equal to 2.000 inches.

8. The modular cartridge system of claim 7, wherein the case length is between 0.500 inches and 1.400 inches.

9. The modular cartridge system of claim 7, wherein the case length is between 1.400 inches and 2.000 inches.

10. The modular cartridge system of claim 7, wherein the cartridge case comprises a substantially cylindrical first portion having a first diameter, a substantially cylindrical second portion having a second diameter, the second diameter being smaller than the first diameter, and a conical portion intermediate the first and second portions, wherein the projectile is seated within the second portion of the case.

11. The modular cartridge system of claim 10, wherein the plurality of cartridges include a rebated rim.

12. The modular cartridge system of claim 7, wherein the case diameter is substantially constant along the length of the case.

13. A modular cartridge system for firearms, the system comprising:

a plurality of cartridges each having a base, a rim, a case, and a projectile coupled to the case;

wherein each cartridge of the system include base and rim dimensions that are functionally equivalent;

wherein the diameter of the projectile is variable between 0.220 inches and 0.4050 inches; and

wherein the length of the case is variable between 0.500 inches and 2.000 inches.

14. The modular cartridge system of claim 13, wherein a first portion of the plurality of cartridges have a constant cross-sectional diameter and a second portion of the plurality of cartridges have a variable cross-sectional diameter.

15. The modular cartridge system of claim 13, wherein a first group of cartridges has a case length of between 0.500 inches and 1.400 inches, and a second group of cartridges has a case length of between 1.400 inches and 2.000 inches.

16. The modular cartridge system of claim 13, wherein the plurality of cartridges includes rifle-based cartridges and pistol-based cartridges.

17. The modular cartridge system of claim 13, wherein the cartridge cases are between about 50%-80% of the overall length of the cartridges.
