The Canned Heat Cyalume shotgun ammunition is something special. These 12 Gauge 3/4 oz #8 shot loads include a chemical tracer made by Cyalume. Cyalume manufactures chemical light sticks. The tracer is simply a short light stick that is activated when the round is fired. Unlike conventional tracers it poses no fire hazard. The technology was jointly developed by Cyalume, Fiocchi, General Dynamics and Rheinmetall Defence.
