Abstract Frangible firearm projectiles, firearm cartridges containing the same, and methods for forming the same. A frangible firearm projectile includes a frangible projectile body consisting essentially of a compacted mixture of metal powders that forms at least 90 wt% of the frangible projectile body. The frangible firearm projectile includes an anti-sparking agent configured to reduce a propensity for the frangible firearm projectile to produce sparks upon striking a target after being fired; and further wherein the anti- sparking agent includes at least one of boric acid, borax, and a borate.

FRANGIBLE FIREARM PROJECTILES, METHODS FOR FORMING THE SAME, AND FIREARM CARTRIDGES CONTAINING THE SAME
Frangible firearm projectiles, firearm cartridges containing the same, and methods for forming the same. The firearm projectiles are formed from a compacted mixture of metal powders that includes zinc and iron powders and which may include an anti-sparking agent. The compacted mixture is heat treated for a time sufficient to form a plurality of discrete alloy domains within the compacted mixture. The frangible firearm projectile may be formed by a mechanism that includes vapor-phase diffusion bonding and oxidation of the metal powders and that does not include forming a liquid phase of any of the metal powders or utilizing a polymeric binder. A majority component of the frangible firearm projectile may be iron. One or more of zinc, bismuth, tin, copper, nickel, tungsten, boron, and/or alloys thereof may form a minority component of the frangible firearm projectile. The anti-sparking agent may include a borate, such as boric acid.

PROJECTILE ASSEMBLY WITH STABILIZATION/OBTURATION ENHANCEMENT
A projectile assembly comprises a base portion for receiving projectiles such as slugs and has an associated pusher plate at a rear end thereof for minimizing or controlling deformation of the rear end of the base portion during firing. The pusher plate has a disc with one or more axially extending projections that extend axially into the rearward end of the base portion thereby reinforcing the base portion and upon firing providing uniform axial deformation and/or obturation of the base portion with respect to a firearm barrel. The projectile assembly may be, for example, part of a shotgun shell slug cartridge, or may be a muzzle loaded projectile seated on propellent in a muzzle loader and provides enhanced accuracy over the prior art.
A bullet system including a bullet body with a tail portion engaged with a polymer cup that provides enhanced engagement of the barrel upon firing. The bullet system may have a radial retracted state that corresponds to an elongated axial state of the bullet system that allows the cupped bullet to be fed down the barrel at a reduced diameter with reduced engagement with the barrel. The radial expansion of the bullet system occurs upon axial length reduction of the bullet system by axial compression. The axial compression can occur upon firing of the propellant or when loading with the ramrod. The bullet system can provide a tactile seat force indicator tip insert within the tip of the bullet body that provides a tactile sensation when the bullet is properly seated against the propellant charge. A cutting edge may be provided for scraping the barrel upon insertion of the bullet.
Muzzleloader systems include a pre-packaged propellant charge and primer for providing efficient loading and unloading of the muzzleloader. The breech end accepts the propellant and means are provided to prevent breech loading of the projectile. A propellant cartridge conforms to a constriction portion to minimize ullage. A projectile is inserted in the muzzle end seats on the constriction portion. The propellant cartridge may be received in a removable breech plug. The constriction portion may be part of the breech plug or a separate component secured in the barrel by way of the breech plug. The cartridge may have a primer mechanism integrated into a proximal end. Projectiles have sliding components that have an axial elongate position and an axial shortened position and may be loaded with a ramrod having an engagement portion for each of the two pieces whereby the projectile doesn't prematurely collapse.

The sensitivity of the primer composition is created by the interaction between the moderately insensitive explosive and the fuel agent such that traditional primary explosives such as lead styphnate or DDNP are not needed. The primer composition also eliminates the risks and dangers associated with traditional nano-sized fuel particles.
