text: A "tracer" is a cartridge which is constructed by loading a special bullet, having a hollow base, and containing a compound which ignites when exposed to the burning powder present in a cartridge case and consequently in the barrel as the round is fired, and which continues to burn as the bullet exits the barrel and passes through the air to the target.
