Underwood Ammo 45-70 Government +P 325gr Xtreme Hunter - 20 Rounds

The Underwood Ammo 45-70 Government +P 325gr Xtreme Hunter delivers devastating terminal performance for big game hunting and dangerous game scenarios. This premium hunting ammunition combines Underwood's signature high-pressure loading with a specialized 325-grain projectile engineered for maximum penetration and expansion.

What Makes This Different

Unlike standard 45-70 loads that operate at traditional pressure levels, this +P configuration generates significantly higher velocities while maintaining safe pressures in modern firearms. The Xtreme Hunter bullet design features a solid copper construction with engineered expansion petals that create massive wound channels. Velocity reaches approximately 2,050 fps from a 24-inch barrel, delivering over 3,000 foot-pounds of muzzle energy.
