Barnes TAC-XPD 40 S&W Ammo 140 Grain TAC-XP Hollow Point Lead-Free ammo review offers the following information; Barnes TAC-XPD ammunition is optimized for carry and home defense use. Loaded with the popular Barnes TAC-XP bullet it is designed to deliver top performance when it matters the most. The TAC-XP's all-copper construction and very large, deep hollow-point cavity expand, penetrate and perform more consistently than any personal defense product on the market. Performance through bare gel, light and heavy clothing, car doors, plywood and automotive windshield glass is unmatched by the competition. TAC-XP bullets are 100% copper, making them safe for the environment. These lighter all copper bullets also result in less felt recoil in comparison to lead core bullets allowing the shooter to recover quickly without sacrificing terminal performance.
