Tracer ammunition contains pyrotechnic composition at the base of the bullet, which ignites upon firing to create a visible trace of the bullet's trajectory in flight. This allows shooters to track the path of the bullet and make adjustments if needed. Tracer rounds are primarily used for training purposes or in military applications.
