Hornady Ammunition 155 Grain Jacketed Hollow-Point (JHP) Ammo Details

Want to give your Glock 20 some real power for self-defense? Then you only need stuff its magazine with this fine ammo from Hornady’s Custom label. This 10mm cartridge showcases Hornady’s own 155 grain XTP (eXtreme Terminal Performance), a hollow point bullet with an impressive jacket that boosts performance in a number of ways. First, it’s concentric, as Hornady’s bullets are known to be. Second, it is precisely divided into symmetrical sections and has varying thicknesses engineered throughout its length, both of which make its expansion more reliable. Finally, the jacket protects the lead that would otherwise have been exposed by the nose cavity. That also promotes reliable expansion, but helps feeding to occur in a semi-automatic pistol as well. As Customs, these rounds have also got fine brass casings that Hornady either made or at least inspected themselves, and propellant measured to create a stable chamber pressure with every shot.
