Underwood Ammo Xtreme Hunter Rifle .45-70 Govt 325Gr Monolithic Solid

The Underwood Ammo Xtreme Hunter Rifle .45-70 Govt 325Gr Monolithic Solid is a modern take on America's most iconic big-game cartridge. Built on non-corrosive, reloadable brass, this ammunition delivers the velocity and power hunters expect from the .45-70, with a 325-grain monolithic copper bullet engineered for deep penetration and consistent expansion. At 2030 fps and 2974 ft-lbs of muzzle energy, it's a serious choice for hunters working from levergun to Sharps, and it shoots supersonic, so you get the ballistics you plan for.

The monolithic solid construction means no lead core, no separation—just a single-piece copper projectile that holds together through bone and gristle. The 0.221 sectional density and 0.23 G1 ballistic coefficient tell you this bullet is built to penetrate, not expand violently. That's exactly what the .45-70 was designed for: deep, reliable performance on big game where shot placement and penetration matter more than explosive fragmentation.

Whether you're hunting elk, moose, or reaching back to magnum rifle performance with a lever gun, this load gives you modern ammunition engineering in a time-tested platform. The nickel-plated brass handles the pressures smoothly and stands up to field conditions. And if you're running a suppressor, you can shoot these with confidence—they're rated safe for suppressed fire. Each box contains 20 rounds of loaded ammunition, so you get what you need to hunt or test your rifle's performance.
