20rds – 10mm Underwood 200gr. Hard Cast Ammo

Underwood Ammo 200 Grain Hard Cast Ammo Details

This 10mm cartridge is loaded with a 200 grain hard cast projectile. The non-expanding bullet’s exceptional hardness enables to penetrate very deeply, and its flat nose is designed to keep it on a straight path. You’d have a much easier time convincing a bear not to bother you with one of these loads in your chamber, and a hard cast’s greater ability to ignore hide makes this round good for taking wild boar as well.

Underwood jacketed this round’s bullet with polymer-based Hi-Tek, which helps the hard cast to stave off bore fouling like an FMJ would. In addition to keeping the bore cleaner, Hi-Tek makes the shooter’s environment cleaner by reducing airborne lead. This round features a Ducta-bright 7a nickel plated brass casing, which provides all the performance benefits of nickel but with less risk of cracking or failure. If you plan to use this round on crepuscular game, then you’ll appreciate its flash suppressed powder’s ability to preserve your night vision.
