Which type of ammunition can potentially cause serious injury or death when fired at close range?

The selection of blank round ammunition as a type that can potentially cause serious injury or death when fired at close range is based on the understanding of how blank ammunition operates. While blank rounds are designed to produce a gunshot sound and simulate the firing of a bullet without a projectile, they still contain gunpowder and a wad or plug that creates a forceful discharge of gas.

When fired at such close range, the energy released can still inflict severe injuries. The proximity can result in burns, lacerations, or even fatal injuries, especially if the wad or materials expelled from the weapon strike a person. This point emphasizes that while blank rounds do not have a traditional bullet, they still pose a significant risk due to the explosive force they generate.

The other types of ammunition listed have different intended uses and safety profiles. Hollow-point ammunition is designed to expand upon impact, increasing stopping power while potentially reducing the risk of over-penetration. Frangible ammunition is made to break apart upon impact, minimizing the risk of ricochets and ensuring safer use in certain environments. Lead round nose ammunition, while it can be dangerous, is typically designed for traditional bullet performance and relies on direct impact to be lethal rather than the hazards associated with gas discharge.
