Underwood Ammo
The Underwood Ammo Xtreme Hunter 357 Magnum 120-grain solid monolithic round is built for hunters and sport shooters who demand reliable, hard-hitting performance from their .357 Mag revolvers and carbines. These all-copper, one-piece projectiles deliver consistent terminal performance without the complexity of traditional jacketed bullets—and they're loaded to Underwood's reputation for pushing the envelope on power and velocity.
Solid monolithic bullets are prized by serious hunters because they generate minimal fouling, shed no jacket fragments, and offer excellent weight retention through barriers and game. The 120-grain bullet weight in .357 Magnum hits a sweet spot for hunting medium game and self-defense work: it's light enough to generate impressive velocity from a handgun platform, yet heavy enough to carry real kinetic energy downrange. Each box contains 20 rounds, and this product is sold in a 10-box case, giving you 200 rounds per case for range days, testing, or stocking up.
If you run a .357 Mag revolver or lever-action carbine and want ammunition that punches above the factory standard, or if you're building a handloading library with quality factory rounds as a reference point, Underwood's Xtreme Hunter line delivers the engineering and performance you'd expect from a premium ammo maker. This is the kind of round that earns its place in your range bag or hunting pack through real-world reliability, not just marketing noise.

This ammunition is chambered in .357 Magnum, so it will fire reliably in any firearm designed for that caliber—including .357 Mag revolvers, lever-action carbines, and other compatible platforms. Always verify your firearm's chamber markings before loading.
Solid monolithic bullets are constructed from a single piece of copper with no jacket to separate. They generate less fouling in your barrel, retain their weight through barriers and game better than many jacketed designs, and deliver consistent terminal performance. They're especially valued by hunters pursuing medium game and serious shooters who want maximum reliability and minimal cleanup.
Each case contains 10 boxes of 20 rounds, totaling 200 rounds of Xtreme Hunter .357 Magnum ammunition.
Yes—the 120-grain solid monolithic design is engineered for hunting applications, offering the penetration and energy retention needed for taking medium game with a .357 Magnum revolver or carbine.
