The Barnes XPB Pistol Bullets.357 Mag, 140 gr (part no. 30453) are all-copper handgun bullets from Barnes, built around Barnes’ patented X-Bullet design and sold 20 to a box for handloaders building their own .357 Magnum ammunition. Because there’s no lead core, the XPB avoids the core-jacket separation that can rob a conventional jacketed bullet of weight and penetration on impact. Barnes designs the all-copper hollow point to expand reliably while retaining nearly all of its original weight, translating into deeper penetration and more transferred energy than a comparable jacketed lead-core bullet.
