A bullet that will retain markings from a firearm barrel when fired from such firearm. The bullet comprises a right cylindrical core with opposed ends, one such opposed end having a tapered section integrally connected thereto. The core is formed from a lead-free composition of a polymer and filler

A bullet that will retain markings from a firearm barrel when fired from such firearm. The bullet comprises a right cylindrical core with opposed ends, one such opposed end having a tapered section integrally connected thereto. The core is formed from a lead-free composition of a polymer and filler and selectively retains it's integrity when fired from the firearm or is frangible. The right cylindrical core has a jacket that is cylindrical and formed from a thermoplastic polymer or copper. The thermoplastic polymer has a softening point above firearm barrel temperatures.

[ What is claimed is:] [1.]1. A bullet that will retain markings from a firearm barrel when fired from such firearm, comprising:a right cylindrical core with opposed ends, one such opposed end having a tapered section integrally connected thereto, said core being formed from a lead-free composition comprising a filler and a polymer, said polymer being selected from the group consisting of amorphous polymers, low crystallinity polymers and combinations thereof, said composition retaining its integrity when fired from the firearm, said right cylindrical core having a jacket that is cylindrical and formed from a thermoplastic polymer or copper, said thermoplastic polymer having a softening point above firearm barrel temperatures, the adhesion between the jacket and the core being sufficient to retain the integrity of the bullet on firing until impact, said bullet having a weight that is at least 80% that of a comparable bullet for such firearm, said comparable bullet being formed from lead.
