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.
