1. A non-lethal paintball projectile comprising
a body component made of a single piece and having a uniform continuous structure and surface forming outer surfaces of a front portion and a side wall of a body portion,
a closed cavity in an interior volume of the front portion, and
a fill in the closed cavity,
wherein
a length of the projectile is at least 15 mm,
a length of the front portion is equal to or less than 9.7 mm,
wherein the projectile further comprises:
a middle component in an interior volume of the body component, the middle component being a disc-shaped middle wall inside the body component, placed between the front portion and the body portion and being supported by supports extending inward from an inner surface of the front portion, and the middle component further having a first side and a second side,
wherein
the first side of the middle component is facing the closed cavity,
the projectile further comprises an open cavity in an interior volume of the body portion,
the second side of the middle component is facing the open cavity, and
the projectile further comprises a barrier layer on the second side of the middle component.
 
14. A method for manufacturing a non-lethal paintball projectile, the method comprising:
supplying a body component made of one piece and having a uniform continuous structure and surface forming outer surfaces of a front portion and a side wall of a body portion,
applying a fill into the front portion of the body component,
shaking the body component to level the fill out,
providing a middle component being a disc-shaped middle wall configured to be placed between the front portion and the body portion, and the middle component having a first side and a second side,
inserting the middle component into the interior volume of the body component so that the first side of the middle component is facing the interior volume of the front portion, and the second side of the middle component is facing the interior volume of the body portion, thereby forming one closed cavity and one open cavity,
applying a sealing agent on the second side of the middle component, thereby obtaining a barrier layer on the middle component, and optionally drying the barrier layer,
thereby obtaining the projectile.
