Abstract: An apparatus is disclosed including a bore cleaning device configured to clean a bore of a firearm. The device includes a propellant providing a force to push the projectile down the bore of the firearm, a fibrous cup, a dense material within the fibrous cup, and a frame including a bore forward disk configured to press against a bottom surface of the fibrous cup. The dense material includes one of a dense granulated material and a dense, viscous paste. The dense material is configured to deform and press radially outwardly against the cup as the propellant provides propelling force to the dense material.

Abstract: A bore cleaning device is disclosed that is configured to clean a bore of a firearm. Devices disclosed herein receive force manually applied by the user to push, pull, or propel the device through the bore. The device includes an internal mechanism configured to translate one of a pushing force and a pulling force into an outward radial force forcing intimate contact between device surfaces and interior walls of the bore.

Abstract: A bore cleaning projectile cleans a bore of a firearm as the projectile is propelled down the bore. The projectile includes a frame including a lower charge cap, a tapered cone-shaped center shaft portion, and an end cap. The projectile further includes a propellant providing a force to push the device down the bore of the firearm and at least one cleaning agent situated around the tapered cone-shaped center shaft portion. The center shaft portion includes a narrower diameter at a longitudinally forward portion of the center shaft portion and a wider diameter at a longitudinally rearward portion of the center shaft portion. The cleaning agent is forced to move along the center shaft portion toward the longitudinally rearward portion of the center shaft portion as the frame is propelled down the bore. This movement along the center shaft portion causes intimate contact between the cleaning agent and the bore.
