Nosler Defense ammunition is an excellent self-defense load featuring the new Bonded Performance bullets. Performance bullets were designed with the same technology as Nosler's trusted AccuBond bullet which eliminates the possibility of jacket/core separation. The resulting bullet retains nearly 100% of its original weight. At the same time a tapered jacket and lead alloy core produce reliable expansion. Nosler Defense ammunition is available with either a polymer tipped or jacketed hollow point bullet. - Caliber: 10mm - Bullet Type: Jacketed Hollow Point - Bullet Weight: 200 gr - Muzzle Velocity: 1000 fps - Muzzle Energy: 444 ft / lbs - Rounds Per Box: 20
