Design of non-lead rifle bullets to allow instant identification

Abstract

A design feature for non-lead bullets was proposed enabling visual distinction from lead-core bullets. The feature would allow rapid, non-invasive, examination of ammunition to ensure compliance with lead-free bullet regulations. The feature entails making symmetric flutes, or concentric rings, behind the bullet tip during manufacture. They are unlikely to affect bullets’ ballistic performance. Should the design be adopted, agreement among governmental agencies and bullet makers is essential to incorporate this design protocol into regulations.
