Abstract
Tracer ammunition is disclosed and includes a projectile having a body; a chamber in the body having a front end and a rear end, the rear end of the chamber being open; an aperture at a rear end of the body providing an opening to the open end of the chamber; and a tracer material disposed within the chamber, wherein the tracer material is configured to combust when ignited and emit optical energy through the aperture as a result of the combustion process. The tracer material may be configured to include a rear-facing surface having a concave contour to aid in directivity of light output from the tracer material.
