Barnes M/LE TAC-XP Pistol Bullets .40 S&W/10mm .400" 125 gr FB HP 40/ct
The Barnes M/LE TAC-XP pistol bullets in .40 S&W/10mm are engineered for serious handgun reloaders who demand barrier-blind, lead-free ammunition for defensive and tactical applications. Built entirely from 100 percent copper with no lead core, these 125-grain hollow-point rounds maintain their weight after impact and penetration—a critical advantage when your shot has to perform through windshield glass, plywood, auto body panels, and other intermediate barriers that can degrade traditional projectiles. Each box contains 40 bullets ready to load.
Barnes designed the TAC-XP specifically for law enforcement and professional shooters, but the engineering benefits apply equally to any reloader building defensive rounds for .40 S&W or 10mm pistols. The lead-free construction meets strict environmental standards while delivering the terminal performance that matters downrange. These are not budget plinking rounds—they're precision components for handloads where accuracy and barrier penetration are non-negotiable.
If you're reloading defensive .40 or 10mm ammunition and need bullets that shoot straight through barriers and maintain weight retention, the M/LE TAC-XP puts serious engineering in your hands. The 125-grain bullet weight is popular in both calibers for balancing velocity, recoil, and stopping performance in modern pistols.
