What is claimed is: 1. A toy projectile, comprising: a body having a length extending between a first end to an oppositely disposed a second end, wherein the body has a substantially cylindrical shape; a nub portion extending from the second end, the nub portion having a diameter smaller than a diameter of the body at the second end, such that a step is defined between the second end and the nub portion, wherein the nub portion has a length extending between a first nub end and a second nub end, the first nub end is contiguous with the second body end, and the second nub end terminates in a flat or substantially flat surface; a tip attached to the body at the first end; and one or more fins attached to or integrally formed with the body at the second end upstream the nub portion. 2. The toy projectile of claim 1 , wherein a ratio of the body length to the nub portion length is about 12:1 to about 20:1. 3. The toy projectile of claim 1 , comprising 6 fins spaced to surround a circumference of the body. 4. The toy projectile of claim 1 , wherein the nub portion length is about 1 to 5 mm. 5. The toy projectile of claim 1 , wherein the nub portion comprises a circumferential wall joining a first nub end at the second end and an oppositely disposed second nub end, wherein the circumferential wall tapers inwardly from the first nub end to the second nub end. 6. The toy projectile of claim 5 , wherein the circumferential wall has a taper of about 100°. 7. The toy projectile of claim 1 , wherein the nub portion comprises a circumferential wall joining a first nub end at the second end and an oppositely disposed second nub end, wherein the circumferential wall is a straight non-tapered wall. 8. The toy projectile of claim 1 , wherein the body has a length defined between the first and the second end of about 50 mm to about 100 mm. 9. The toy projectile of claim 1 , wherein the body has a reduced diameter portion at the first end and the tip is sized to fit over the reduced diameter portion. 10. The toy projectile of claim 1 , wherein the body is formed from an expanded beaded material. 11. The toy projectile of claim 10 , wherein the expanded beaded material is one or more of expanded beaded polyethylene, expanded beaded polypropylene, expanded beaded polystyrene, expanded beaded thermoplastic polyurethane, and expanded beaded polylactic acid. 12. The toy projectile of claim 1 , wherein the length of the body is about 60 mm to about 70 mm, and the length of the nub portion is about 3 mm to about 5 mm. 13. A toy projectile, comprising a body extending from a first end to a second end, wherein the body has a boat tail structure, such that a diameter of the body tapers from a maximum body diameter towards the second end to define a nub portion having a nub diameter less than the maximum body diameter; one or more fins disposed on the body adjacent the second end around a circumference of the body, wherein an outer circumference is defined by the outer surface of the one or more fins and a diameter of the outer circumference is substantially the same as the maximum body diameter, wherein the one or more fins are positioned on the body such that the toy projectile has a substantially constant diameter along a length of the toy projectile extending from the maximum body diameter to the one or more fins having the outer circumference; wherein the one or more fins terminate at fin ends upstream the nub portion, such that the nub portion extends outwardly defining a reduced circumferential portion as compared to an outer circumference defined by the one or more fins and a step is defined between the fin ends and the nub portion. 14. The toy projectile of claim 13 , wherein a ratio of the maximum body diameter to the nub diameter is about 10:1 to about 1.25:1. 15. The toy projectile of claim 13 , wherein a difference between the maximum body diameter and the nub diameter is about 0.5 mm to about 3 mm. 16. The toy projectile of claim 13 , comprising 6 fins spaced to surround a circumference of the body. 17. The toy projectile of claim 13 , wherein the nub portion comprises a circumferential wall joining a first nub end at the second end and an oppositely disposed second nub end, wherein the circumferential wall tapers inwardly from the first nub end to the second nub end. 18. The toy projectile of claim 13 , wherein the body has a length defined between the first and the second end of about 50 mm to about 100 mm. 19. The toy projectile of claim 13 , wherein the body has a reduced diameter portion at the first end and a tip is sized to fit over the reduced diameter portion. 20. The toy projectile of claim 13 , wherein the body is formed from an expanded beaded material. 21. The toy projectile of claim 20 , wherein the expanded beaded material is one or more of expanded beaded polyethylene, expanded beaded polypropylene, expanded beaded polystyrene, expanded beaded thermoplastic polyurethane, and expanded beaded polylactic acid. 22. A toy projectile, comprising: a body extending from a first end to a second end; a plurality of fins attached to or integrally formed with the body at the second end, wherein the body including the fins has a substantially uniform first diameter, each fin being separated from adjacent fins by a space, wherein a portion of the body disposed in the space is tapered inwardly along a length of the fin towards the second end; a nub portion extending from the second end, wherein nub portion has a second diameter that is less than the first diameter; and a tip attached to the body at the first end. 23. The toy projectile of claim 22 , wherein a ratio of the first diameter to the second diameter is about 10:1 to about 1.25:1. 24. The toy projectile of claim 22 , wherein a difference between the first diameter and the second diameter is about 0.5 mm to about 3 mm. 25. The toy projectile of claim 22 , comprising 6 fins spaced to surround a circumference of the body. 26. The toy projectile of claim 22 , wherein the nub portion comprises a circumferential wall joining a first nub end at the second end and an oppositely disposed second nub end, wherein the circumferential wall tapers inwardly from the first nub end to the second nub end. 27. The toy projectile of claim 22 , wherein the nub portion comprises a circumferential wall joining a first nub end at the second end and an oppositely disposed second nub end, wherein the circumferential wall is a straight non-tapered wall. 28. The toy projectile of claim 22 , wherein the body has a length defined between the first end and the second end of about 50 mm to about 100 mm. 29. The toy projectile of claim 22 , wherein the toy projectile is formed from an expanded beaded material, the expended beaded material being one or more of expanded beaded polyethylene, expanded beaded polypropylene, expanded beaded polystyrene, expanded beaded thermoplastic polyurethane, and expanded beaded polylactic acid. 30. The toy projectile of claim 22 , wherein the length of the body is about 60 mm to about 70 mm, and a length of the nub portion is about 3 mm to about 5 mm.
