Abstract
Methods and articles are provided for frangible slugs. A method of manufacturing a frangible slug includes heating substantially spherical metallic powdered particles, wherein substantially all of the powdered particles have diameters larger than 125 microns and smaller than 250 microns, to form heated powdered particles. The method includes heating a microcrystalline wax, to form a melted wax. The method also includes combining the heated powdered particles with the melted wax, to form a liquid mixture. The method further includes filling a payload cavity of a frangible slug container with the liquid mixture to form a liquid mixture payload.
Claims21
A method of manufacturing a frangible slug, comprising:
- heating substantially spherical metallic powdered particles, wherein substantially all of the powdered particles have diameters larger than 125 microns and smaller than 250 microns, to form heated powdered particles;
- heating a microcrystalline wax, to form a melted wax;
- combining the heated powdered particles with the melted wax, to form a liquid mixture;
- and
- filling at least a portion of a payload cavity of a frangible slug container with the liquid mixture to form a liquid mixture payload.
A frangible slug, comprising:
- a substantially cylindrical container with a payload cavity defined, at least in part, by an inside surface of the container;
- and
- a frangible payload including a solid mixture of substantially spherical metallic powdered particles bound in a microcrystalline wax, wherein the frangible payload:
- substantially fills the payload cavity;
- is exposed on an open end of the container;
- and
- is mechanically retained inside the payload cavity.
A firearm cartridge, comprising:
- propellant, configured to accelerate a composite projectile package to a particular muzzle velocity, after the cartridge is fired;
- and
- the composite projectile package, including a frangible payload, wherein the frangible payload:
- includes a solid mixture of substantially spherical metallic powdered particles bound in a binder, wherein substantially all of the powdered particles have diameters larger than 125 microns and smaller than 250 microns;
- and
- is configured to substantially disintegrate, when the package impacts a stationary solid object at a velocity that is substantially equal to the particular muzzle velocity.
