Barnes Tac-Xpd DefenseHandgun Cartridges .357 Magnum TAC-XP 125 Grain 20 - Rounds 21550. Barnes's development team used real-world testing to evaluate the true terminal performance of various bullet types. They were startled to find that many of these bullets had actually lost energy upon impact even at low velocities. They immediately went to work designing a bullet that would retain energy and function even at those low velocities. Over the years the Tac-XPD Defense handgun cartridge has become a popular choice among professional law enforcement agencies all over the world. Since the handgun version of this ammunition is a development of a wildcat designed to evade police and fire in crowded urban settings it was the perfect tool for the task. New production 357 Magnum cartridges from Barnes deliver great terminal performance but at those critical times of the day they deliver terminal performance at great velocities. Barnes has continued to engineer new innovative ways to reliably shoot these bullets. As an avid shooter of both pistol and rifle myself I know I can always count on my Bench Rest to keep my pistol loaded with only premium quality ammo that I can depend on to get me through the day.
