Our .357 Magnum ammunition is crafted to meet SAAMI specifications while delivering exceptional recoil and power. For those who dare to shoot from lightweight titanium, scandium or aluminum alloy revolvers, we recommend loading only one or two rounds at a time. For optimal performance and safety, we advise using these high-powered rounds in steel revolvers, which can better handle the intense recoil. The severe recoil can potentially dislodge projectiles in smaller, lighter firearms, so caution is advised when fully loading snub-nose revolvers. Underwood Ammo XTP rounds are engineered for unparalleled performance. Featuring Hornady eXtreme Terminal Performance (XTP) bullets, they offer deep terminal penetration, exceptional accuracy and controlled expansion. Our proprietary formulation enhances these already outstanding bullets, resulting in a round that delivers lethal effectiveness. Our nickel-plated brass casings provide several advantages over traditional brass, improved feeding in all firearm actions, enhanced corrosion resistance, superior appearance and ease of cleanup during reloading. The nickel plating ensures that casings resist tarnishing and remain unaffected by moisture, leather and other materials. Each round is loaded with flash-suppressed powder to ensure clear vision in low-light conditions. We rigorously test our ammunition with real-world firearms to ensure it performs to the highest standards. This ammunition is new production, non-corrosive, boxer-primed and reloadable in durable brass cases. Experience the superior power and precision of Underwood Ammo .357 Magnum XTP and elevate your shooting performance to new heights.
