"Ten bullets through one hole" is the philosophy that brought Hornady Manufacturing from a two-man operation in 1949, to a world-leading innovator of bullet, ammunition, reloading tool and accessory design and manufacture today. Hornady outperforms their competitors by ensuring the products they make are what the customers want right now, and then accurately predict and manufacture what they'll want and need in the future. Handgun shooters looking for supreme accuracy and maximum knock down power have come to rely on Hornady Custom pistol ammo, loaded with either the famous Hornady XTP (Extreme Terminal Performance) bullet, our FMJ or FTX bullet. Every round of Hornady Custom ammunition is hand inspected before packaging to ensure the highest levels of quality control. At Hornady, they manufacture Custom ammunition to give shooters and hunters the advantage of hand-loaded accuracy in a factory load.Specifications:Caliber: 10mm AutoBullet Type: Hornady XTP Jacketed Hollow Point (JHP) BulletBullet Weight: 180 GrainsRounds: 20 Rounds per boxMuzzle Velocity: 1180 fpsMuzzle Energy: 556 ft/lbsSectional Density: .161Ballistic Coefficient: .164Jacket Material: CopperCore Material: LeadTip Material: NoneCasing: Reloadable Brass CaseUses: Self Defense, Home Protection, and Duty Ammunition
