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. Its central core should expand to 150 percent of the original diameter, retain 75 percent or more of the projectile’s weight and penetrate not less than 12 inches of ballistic medium. This ammo is assembled to exact specifications with commercial-grade machinery and is designed to deliver the accuracy that precision shooters demand. Specifications: 9mm Luger +P/147 gr/Bonded Match Hollow Point/50 Per Box/10 Cs
