At what distance do 7.62mm tracers burn out?

• A. ~700m
• B. ~1100m
• C. ~900m
• D. ~1300m

Answer: (C)

Tracer rounds carry a small pyrotechnic mix that lights up as the bullet flies and continues burning for a limited time. The visible flame lasts only while that burn fuel is still burning, so the tracer stops being visible when the burn-out distance is reached. For standard 7.62mm NATO tracers, that burn-out distance is typically around 900 meters, which is why this distance is used as the reference. Beyond that range the tracer flame is usually extinguished and you’d see only the bullet without the bright tracer tail. The other distances aren’t the typical burn-out point for this ammunition, since they fall outside the normal burn duration of the tracer compounds under expected conditions.
