This disclosure provides for payload delivery systems and cartridges and methods that incorporate the payload delivery systems. The payload delivery system can comprise a stabilizer having a longitudinally cut side wall defining a series of vanes that are folded forward in the pre-launched configuration. Cartridges that include the payload delivery system are disclosed, which can be used to deliver payloads such as solid projectiles, shot of all sizes, powders, gels, liquids, and other payloads to exploit their specific function.

1. A payload delivery system comprising, in its pre-launched configuration: a stabilized payload cup formed of a tube having a payload cup section with an outer surface and a contiguous stabilizer section, the stabilizer section having an edge and a plurality of longitudinal slits defining a plurality of vanes extending rearward from the payload cup section to the edge of the stabilizer section, in which the vanes of the stabilizer section are forward folded along a least a portion of the outer surface of the payload cup section, thereby defining an open fore end, an open aft end, and a cylindrical side wall, the cylindrical side wall defining a cavity that terminates at a fore edge and an aft edge;wherein the forward folded vanes of the stabilizer section extend from the aft edge along at least a portion of the length of the cylindrical side wall. 2. A payload delivery system according to claim 1, further comprising a pre-formed gas seal coaxially aligned with the stabilized payload cup and adjacent the aft end. 3. A payload delivery system according to claim 1, further comprising a pre-formed gas seal coaxially aligned with the stabilized payload cup and adjacent the aft end, wherein the pre-formed gas seal is situated at least partially within the cavity defined by the cylindrical side wall, or the pre-formed gas seal is attached to the stabilized payload cup. 4. A payload delivery system according to claim 1, further comprising a gas seal comprising an obturating medium adjacent the aft end. 5. A payload delivery system according to claim 1, wherein the plurality of forward folded vanes extend less than or equal to the length of the cylindrical side wall from the aft end to the edge of the stabilizer section. 6. A payload delivery system according to claim 1, wherein the plurality of forward folded vanes extend greater than the length of the cylindrical side wall from the aft end to the edge of the stabilizer section. 7. A payload delivery system according to claim 1, wherein the stabilizer section comprises at least 3 vanes. 8. A payload delivery system according to claim 1, wherein the plurality of vanes of the stabilizer section invert from forward folded to rearward folded during flight of the stabilized payload cup. 9. A payload delivery system according to claim 1, wherein a portion of the vanes are removed from the aft edge of the stabilized payload cup. 10. A payload delivery system according to claim 1, wherein the stabilized payload cup comprises paper, polymer, polymer coated paper, composite, laminate, or textile. 11. A payload delivery system according to claim 1, wherein the stabilized payload cup comprises polyethylene, polypropylene, or poly(vinyl chloride). 12.
