Underwood 45-70 Govt+p 225gr - Xtreme Hunter 20rd 10bx/cs

The Underwood 45-70 Govt+p 225gr Xtreme Hunter ammunition delivers premium ballistic performance for hunters and precision shooters who demand reliability in the field. Designed for the classic 45-70 Government cartridge with pressure-optimized +P loading, this round combines raw stopping power with controlled expansion, making it ideal for large game hunting and long-range target work. Each box contains 20 rounds, allowing shooters to develop proficiency and confidence before deployment on live game.

The 225-grain Xtreme Hunter projectile utilizes advanced bullet construction engineered for consistent terminal performance at extended distances. The +P designation indicates this ammunition operates at elevated pressure levels within SAAMI specifications, generating higher velocities and energy retention compared to standard 45-70 loads. This engineering approach produces superior deep penetration and expansion characteristics essential for ethical harvesting of elk, moose, and other large-frame game animals. The carefully balanced propellant charge ensures consistent velocities across the 20-round box, critical for maintaining point-of-impact zero and predictable ballistic performance downrange.

This ammunition is compatible with all modern and vintage 45-70 Government rifles rated for +P pressures, including Marlin lever-actions, Ruger No. 1 single-shots, and Thompson-Center Contenders. Handloaders and competition shooters benefit from quality brass cases and consistent component specifications. For field hunters operating in variable weather and terrain, the compact 20-round packaging (10 boxes per case) offers convenient storage and transport, while maintaining ammunition integrity across temperature extremes. Verify your rifle's pressure rating before use to ensure safe, optimal performance.
