Underwood Ammunition Extreme Terminal Performance 357 Magnum Ammunition 158 Grain Jacketed Hollow Point - 124: The 357 Mag is unique, as it is loaded to SAAMI specifications yet delivers significant recoil. For those who choose to fire these rounds in titanium, scandium, or aluminum alloy-framed revolvers, we suggest loading only one or two rounds in the cylinder at a time. For optimal performance, we recommend firing our 357 Mag loads from steel-framed revolvers. The substantial recoil in smaller frames can sometimes loosen even the strongest crimps on cartridges waiting in the cylinder, potentially causing the projectile to "creep" out of the case. You can use these in a snub-nose 357 Mag, but if you load the cylinder fully, be prepared for some serious recoil. If you have any questions or concerns, please reach out to at
Ammotechs@underwoodammo.com.
Underwood Ammo XTP rounds are renowned for their power and precision. We use Hornady’s eXtreme Terminal Performance (XTP) bullets, engineered for deep penetration, exceptional accuracy, and controlled expansion. The combination of Hornady’s unmatched XTP bullets with their own meticulously formulated design creates a highly effective round.
The nickel-plated brass casings offer several benefits, including smoother feeding across all firearm actions, superior corrosion resistance compared to traditional brass, enhanced appearance, and easy cleanup for reloading. These casings are resistant to tarnishing, even when exposed to leather, moisture, and other materials during storage.
As with all Underwood Ammo™ rounds, they use flash-suppressed powder to ensure that your vision remains clear if you need to fire in low light.
This high-performance ammunition is tested with advanced equipment and popular firearms in real-world conditions, ensuring consistent reliability for our customers.
This is new-production, non-corrosive ammunition, boxer-primed, and reloadable in brass cases.
