This specific type of ammunition, designed for the 5.5645mm NATO cartridge, is constructed to disintegrate into fine dust upon impact with hard surfaces, significantly reducing the risk of ricochet and overpenetration. Typically composed of compressed metal powders held together by a binding agent, these projectiles offer a different performance profile compared to traditional full metal jacket or hollow point rounds.
The reduced risk of unintended harm associated with this ammunition type makes it a consideration for defensive applications in environments where overpenetration is a major concern. By minimizing the chance of projectiles passing through walls or other barriers, the potential danger to bystanders or occupants of adjacent rooms is lessened. This characteristic can be a critical factor in densely populated areas or within the confines of a home.
