Tungsten-containing firearm slug
First Claim
1. A tungsten-containing powder-based shot slug, comprising:
- a body including;
a nose portion configured to first leave a barrel of a firearm from which the slug is fired, and a base portion configured to trail the nose portion through the barrel of the firearm from which the slug is fired, wherein the base portion includes an outer skirt that laterally defines a rear internal recess extending into the body; and
wherein the body is formed via powder metallurgy from at least a tungsten-containing component and a binder.

Abstract
Firearm slugs formed from a non-toxic lead substitute that includes tungsten. In some embodiments, the firearm slug is formed with a recessed back portion, thus shifting an increased percentage of the slug'"'"'s net mass toward the front of the slug. In some embodiments, the firearm slug is formed with a recessed front portion. In some embodiments, the slug is a component of a slug cartridge that includes a slug cup. The slug must have a density that is less than, equal to, or greater than lead, or a lead-antimony alloy used for firearm projectiles. In some embodiments, the slug is formed via powder metallurgy from a powder that includes at least one tungsten-containing component and at least one binder. In some embodiments, the slug is cast or otherwise formed from a molten feedstock that includes at least one tungsten-containing component. In some embodiments, the slug is frangible.
