Availability: In Stock
The Underwood Ammo 348 XTP is a heavyweight .500 S&W Magnum round built for serious power and reliability. Loaded with a 350-grain jacketed hollow point bullet, this ammunition delivers the kind of velocity and energy you need for big-bore handgun hunting and self-defense work. Each box contains 20 rounds of new production ammunition with non-corrosive boxer primers and reloadable brass cases, so you can stretch your investment downrange and get back to reloading once you've put in the work.
At 1912 feet per second muzzle velocity and 2842 foot-pounds of energy, this is a serious round. The XTP hollow point is designed to expand reliably on impact while maintaining the structural integrity needed to reach vital zones on large game. With a sectional density of 0.2, the 350-grain bullet penetrates effectively—a key factor when you're trusting your ammunition to perform when it matters. The ballistic coefficient of 0.145 (G1) means you're working with realistic flight characteristics for a big, heavy projectile; don't expect match-rifle stability, but do expect the energy delivery to match the velocity figures downrange.
Whether you're hunting with a .500 S&W revolver or using it for backup protection in remote areas, Underwood's quality control and consistency make this a round you can trust. The ammunition is safe for use in suppressors if you're running that setup, and the reloadable brass means you can reload and shoot again without breaking the bank on premium big-bore ammo.
