Abstract
Frangible projectiles for firearms and processes for making such projectiles are disclosed. The projectiles include a sintered, compacted iron-based mixture of 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.
Claims11
A lead-free, frangible, sintered firearm projectile, comprising:
- a projectile core formed from cold compacted powder, wherein the cold compacted powder is selected from the group consisting of:
- a mixture of powdered iron particles and powdered copper particles;
- and a mixture of powdered iron particles, powdered copper particles and powdered tin particles.
A process for making a lead-free, frangible, sintered firearm projectile, comprising:
- admixing powdered iron particles with other powdered metal particles;
- cold compacting the admixed powders in a mold to form a projectile core;
- and
- sintering the projectile core at a temperature of 850° F.-1450° F. (454° C.-788° C.).
