Underwood Ammo Xtreme Hunter Features The Underwood Ammo Xtreme Hunter in .357 Mag is built around a solid monolithic copper body that resists deformation when passing through thick hide bone or other barriers a hunter might encounter in the field. The optimized nose flute carries forward technology from the Xtreme Defender line tuned here to maximize penetration depth while generating a permanent wound channel more than twice the size produced by conventional expanding bullets. At 120 grains and 1700 fps the load generates 770 ft lbs of muzzle energy giving medium to large game hunters a round that balances velocity with controlled predictable expansion. Every round is field tested in popular firearms so hunters can trust real-world performance rather than lab numbers alone. Nickel-plated brass casings set this load apart from standard brass-cased ammunition resisting tarnish during storage and improving feeding reliability across a variety of handgun actions. The nickel plating also simplifies cleanup for reloaders and resists corrosion when the casings contact leather moisture or other metals in a hunting pack or range bag. Underwood loads every round with flash suppressed powder so low light hunting situations and dusk encounters with game do not compromise the shooter s vision after the shot breaks. Packed 20 rounds to the box the Xtreme Hunter in .357 Mag gives revolver hunters a purpose-built option for serious medium game pursuits.
