Yes, there are non-incendiary tracer rounds available. While traditional tracer rounds use a pyrotechnic compound to produce a visible trace of light, non-incendiary tracer rounds utilize alternative mechanisms to achieve the same effect. These rounds are designed to be safer and reduce the risk of starting fires. Here are a few types of non-incendiary tracer rounds:

1. Muzzle Flash Tracers: Instead of relying on a burning pyrotechnic compound, these tracer rounds create a bright muzzle flash upon firing, which allows the shooter or observer to track the bullet's path. The flash is typically produced by using specially formulated flash powders or other non-incendiary materials.

2. Cold Tracers: Cold tracers use a combination of special phosphorescent or luminescent materials to produce a visible trace without the use of burning components. These rounds absorb light and then emit it as a visible glow during flight, providing a trajectory reference.

3. Ballistic Tracers: Ballistic tracers work by altering the ballistic properties of the projectile, causing it to follow a slightly different trajectory compared to standard ammunition. The difference in flight path is visually detectable and helps track the bullet's trajectory without the need for incendiary elements.

Non-incendiary tracer rounds are often developed with safety considerations in mind, aiming to reduce the risk of fires caused by traditional incendiary tracers. These rounds are used in various shooting applications, including military training, target shooting, and recreational purposes.
