Atomic Ammunition's 9mm +P ammunition is designed to hit hard, penetrate deep, and shed petals during expansion. The loss of petals allows for additional wound paths, increasing the likelihood of striking a nearby blood vessel, organ, or central nervous system while reducing the core weight to protect against over-penetration. It is assembled to exact specifications with commercial-grade machinery and is designed to deliver the accuracy that precision shooters demand.
