Underwood's .500 S&W Magnum 350-grain XTP ammunition represents serious firepower for those who own a Model 500 or similar large-frame revolver. The load combines Hornady's renowned eXtreme Terminal Performance bullets with Underwood's carefully formulated powders to create a round that performs in the real world with real firearms. You're looking at 1912 feet per second with 2842 foot-pounds of muzzle energy, which translates to devastating terminal ballistics on impact.
The Hornady XTP bullet in this load does the heavy lifting when it comes to performance. These bullets are engineered with a swaged core and drawn copper jacket to ensure expansion stays controlled even at magnum velocities. The hollow point cavity and cannelure design work together to lock the core and jacket during the initial strike, which means you get reliable expansion paired with impressive penetration. This isn't a bullet that either fails to open or over-fragments.
The nickel-plated brass casings offer more than just visual appeal. They're easier to reload thanks to improved corrosion resistance compared to standard brass, and they won't tarnish if they sit in storage next to leather gear or moisture. All Underwood rounds use flash-suppressed powders so your vision stays intact if you need to use your .500 in low light conditions. The ammunition is new production, non-corrosive, and boxer-primed for reloadability.
Underwood field-tests this ammunition in actual firearms that real customers own, not just in controlled lab settings. Each box contains 20 rounds ready to go, and the ballistics are consistent across the entire load. Whether you're taking this to the range, into the field for big game, or keeping it for protection against large predators, you're working with ammunition that was designed from the ground up for serious applications.
Hornady XTP bullets feature a swaged core and drawn copper jacket that works together to create controlled expansion at magnum velocities. The cannelure locks the core to the jacket during impact, so you get reliable opening combined with deep penetration rather than fragmentation or over-expansion.
Yes, all rounds come in boxer-primed, reloadable brass cases. The nickel-plated brass is actually easier to work with during reloading compared to standard brass, and it resists tarnishing during storage.
This load was designed to handle both applications. The controlled expansion and deep penetration characteristics of the XTP bullet make it effective for big game hunting applications like bear or moose, while the velocity and energy levels provide serious stopping capability for protection scenarios.
Yes, all Underwood ammunition uses flash-suppressed powders to preserve your vision if you need to use your firearm in low-light conditions. This is especially useful if your .500 S&W serves a protection role.
