Which of the following is an example of prohibited ammunition?

Tracer rounds are an example of prohibited ammunition in many jurisdictions primarily due to their design and potential hazards. Tracer ammunition contains a pyrotechnic charge that ignites upon firing, allowing the shooter to see the trajectory of the bullet. This feature can be particularly dangerous, as it can cause unintentional fires in environments where flammable materials are present, such as forests or grasslands. Additionally, tracer rounds can pose a risk to safety during tactical operations or in combat scenarios where stealth is crucial, as the bright trail can reveal the shooter's position.

In contrast, other types of ammunition, while they may have specific regulations or restrictions depending on location and scenario, do not carry the same level of inherent risk related to visibility and incendiary potential. Hollow point rounds, for example, are often used for self-defense because they expand upon impact, minimizing the likelihood of over-penetration. Full metal jacket rounds are standard military ammunition designed for reliable feeding and deeper penetration, and lead bullets are commonly used in many shooting sports and hunting without the same level of regulation as tracer rounds.
