Which type of ammunition allows for visual tracking when fired?

Tracer ammunition is specifically designed to allow for visual tracking when fired. This type of ammunition contains a small pyrotechnic charge that ignites upon firing, creating a bright trail of light that follows the projectile through the air. This feature enables shooters to see the trajectory of their shots, making it easier to adjust aim and assess accuracy in real-time.

The other types of ammunition listed do not provide this visual tracking capability. Hollow-point ammunition is designed to expand upon impact, enhancing its stopping power but does not leave a visible trail. Full metal jacket ammunition is known for its smooth feeding and penetration qualities but also lacks any means for visual tracking. Lead round nose ammunition, typically used for target practice and some hunting scenarios, does not offer visual feedback either. Thus, tracer ammunition stands out as the only option that gives shooters an effective means to visually track their shots in flight.
