The present invention relates to longitudinally sectioned bullets and methods that pertain to a penetrable projectile structured to be discharged from a firearm and comprising at least two separable and penetrable, non-fused individual longitudinal body sections and at least one exterior binding element, including at the frontal region of said penetrable projectile, that holds the at least two non-fused individual longitudinal body sections together until they rupture inside of a target, thereby causing the penetrable individual longitudinal body sections to separate away from each other inside of the target as the projectile penetrates the target. The penetrable projectile is thus capable of controlled fragmentation against a soft target, and is optionally adapted to deliver at least one supplemental payload to a target to further damage said target.

Embodiments of the present disclosure provide a firearm cartridge with an electroless nickel bullet coating. In embodiments, a nickel-phosphorous alloy is deposited on a copper bullet to produce a coated bullet, a propellant with a copper inhibiting additive is inserted in a cartridge casing and the coated bullet is inserted in the mouth of the casing. Embodiments of the firearm cartridge include a casing, a propellant with a copper inhibiting additive positioned in the cavity of the casing and a copper bullet secured within the casing, wherein the copper bullet has a nickel-phosphorous coating.

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.

A bullet assembly comprising a bullet and a cup assembly, the cup assembly may have a ring portion for scraping the barrel of a muzzleloader. The cup assembly may be slidable on the bullet with an extended position and a contracted position, the contracted position having a greater diameter than the extended position. A contraction inhibiting member that requires shearing off of the member for contraction may be disposed on one of the components.
