First Claim
Patent Images
1. A lead-free, frangible, sintered firearm projectile, comprising:
- a projectile core formed from an admixture of cold compacted metal powders, consisting essentially of;
powdered iron particles/arepowdered copper particles; and
powdered tin particles;
wherein the powdered iron particles comprise at least 70% by volume of metal particles in the admixture, the admixture is lead-free, and wherein the projectile core is sintered at a temperature in the range of 850°
F. to 1450°
F. (454°
to 788°
C.).

Abstract
Frangible projectiles for firearms and processes for making such projectiles are disclosed. The projectiles include a sintered, compacted mixture of powdered iron particles with other particles, including powdered copper particles and optionally powdered tin particles. The disclosed projectiles produce a similar feel and mimic the ballistic properties of lead projectiles of similar size and caliber, yet readily break-up upon impact with a hard surface in order to minimize ricochet or splatter. The disclosed projectiles and processes for making the projectiles meet the need for inexpensive, lead-free frangible projectiles.
