摘要:
Firearm cartridges, firearm projectiles, and/or projectile components formed at least in part from a disclosed ballistic zinc alloy. These ballistic zinc alloys overcome shortcomings of other lead substitutes for firearm projectiles, including Zamak alloys and other conventional zinc alloys. In some embodiments, and as compared to a firearm projectile formed from a conventional zinc alloy, a ballistic zinc alloy firearm projectile has at least one of an increased ductility, an increased frangibility, and/or a decreased tendency to smear or gall within a rifled firearm barrel. In some embodiments, the ballistic zinc alloy is a zinc-aluminum alloy that includes additional alloy components that collectively enhance the properties of the ballistic zinc alloy for use in firearm projectiles.

摘要:
Corrosion-inhibited copper-containing projectiles and shot shells including the same. The projectiles include a core that is formed from a core material, and an outer coating that is formed from a coating material. The core material includes copper, and optionally may include at least 50 wt % copper. In some embodiments, the outer coating maintains a corrosion rate of copper within the core material below 0.00075 mmpy. The shot shells include a shot charge that includes a plurality of the projectiles.

摘要:
Firearm projectiles with turbulence-inducing surfaces, firearm cartridges including the same, and associated methods. A firearm projectile comprises a projectile body and a turbulence-inducing surface at least substantially enclosing the projectile body. The firearm projectile is at least substantially spherical. The turbulence-inducing surface is configured to induce a drag crisis in a drag coefficient of the firearm projectile when the firearm projectile travels through air with a Reynolds number that is less than 300,000.
摘要:
Firearm projectiles and methods of manufacturing firearm projectiles from a supply of clad wire. In some embodiments, the clad wire is manufactured as electrical wire, such as copper-clad steel wire. Bullets and shot, as well as methods of forming bullets and shot, from clad wire are disclosed.
摘要:
Concealed-projectile firearm cartridges that include taggant-labeled projectiles. A concealed-projectile firearm cartridge includes a cartridge casing adapted to be loaded into a firearm configured to fire the assembled firearm cartridge, a primer and a propellant located within the casing, and at least one projectile at least partially received into the casing. The projectile includes a base material and an identifier material configured to produce an emission, which is configured to be detectable subsequent to passing through the cartridge and prior to firing of the cartridge. The identifier material is configured such that at least one characteristic of the emission is selected to correspond to the base material.
