Specialized ammunition designed for home defense minimizes the risk of overpenetration. These projectiles are constructed from materials that fragment or disintegrate upon impact with solid objects, significantly reducing the chance of unintended harm to individuals beyond the intended target. An example would be copper or sintered metal dust rounds.
The principal advantage of this type of ammunition is enhanced safety for occupants and neighbors. By limiting the projectile’s travel after initial impact, the likelihood of the round passing through walls and endangering others is significantly reduced. This characteristic makes it a suitable choice for residential settings where close proximity to others is a concern. This approach to ammunition design gained traction as awareness of overpenetration risks increased, leading to demand for safer alternatives for self-defense within the home.
