The Underwood Ammo 357 Mag 125-grain XTP load brings proven stopping power to shooters who demand reliable, purpose-built centerfire handgun ammunition. Built on nickel-plated brass cases with non-corrosive boxer primers, these rounds are reloadable—a solid choice for serious handloaders. Whether you're zeroing in at the range, hunting medium game, or building a self-defense battery, this 357 Magnum load delivers the kind of terminal performance that comes from quality controlled manufacturing and thoughtful load development.
The 125-grain Jacketed Hollow Point bullet leaves the muzzle at 1700 feet per second, generating 802 foot-pounds of muzzle energy—enough velocity and power to ensure reliable expansion and penetration in real-world conditions. The sectional density and ballistic coefficient are engineered for stability in flight and consistent performance downrange. Because the round is supersonic and rated safe for suppressed fire, it adapts to a variety of shooting scenarios without compromise. Lead-core construction keeps cost reasonable while maintaining the terminal characteristics that make the 357 Magnum a respected cartridge across hunting and defensive applications.
Each box contains 20 loaded rounds, and Underwood backs the ammunition with consistent quality control. If you're running a revolver or lever-action rifle, or testing loads for your 357 platform, this Underwood offering stacks up against dealer shelves that lean heavily on generic surplus. It's ammunition built by shooters for shooters—no marketing noise, just solid brass and proven bullet design.
