ABSTRACT:
A barrel-cleaning bullet contains a charge of cleaning fluid and an array of cleaning elements that extend about the exterior surface of the bullet. Upon firing of the bullet, a piston, slidably positioned in the cavity filled by the fluid, forces the fluid through at least one discharge port formed in the head of the bullet. The fluid is, thus, distributed along the walls of the gun barrel to treat accumulated deposits. As the projectile accelerates down the barrel, the cleaning elements contact the deposits to clean the barrel bore.
