Underwood 45-70 Govt +p 325gr - Xtreme Hunter 20rd 10bx/cs

The Underwood 45-70 Govt +P 325gr Xtreme Hunter is a magnum-class rifle cartridge engineered for hunters and long-range precision shooters who demand terminal performance in dangerous game and large North American species. This round bridges the gap between traditional .45-70 loads and modern hunting standards, delivering significantly more velocity and energy than factory specifications while maintaining barrel compatibility in +P-rated firearms. Whether pursuing elk, moose, or extended-range hunting applications, this ammunition represents a serious upgrade for lever-action rifle owners and single-shot enthusiasts.

Built by Underwood Ammo, a brand known among law enforcement and civilian shooters for precision handloading, the 45-70 Govt +P features a 325-grain projectile that achieves 2,275 feet per second at the muzzle—a substantial boost over standard .45-70 Government loads. The heavier bullet weight, combined with the +P velocity envelope, generates superior sectional density and retained energy downrange, critical factors for controlled expansion and deep penetration on hard-bodied game. Each case is loaded to modern pressure specifications and paired with quality brass, ensuring consistent ignition and ballistic performance across 20 rounds per box, with bulk availability in 10-box cases.

This ammunition is best suited for shooters with modern or +P-rated .45-70 rifles—lever actions like Marlin 1895 SBL, Henry X Model, and Ruger Number One platforms—and single-shot rifles certified for magnum pressures. Handloaders and reloaders will appreciate Underwood's consistent case quality, which extends component life and supports reload programs common in the long-range rifle community. For hunters operating at moderate to extended distances in heavy cover, the ballistic profile and impact velocity of this 325-grain load deliver the expansion and penetration needed for ethical, one-shot kills.
