Underwood 45lc+p 250gr - Xtreme Penetrator 20rd 10bx/cs

The Underwood 45 LC+P 250gr Xtreme Penetrator ammunition represents a serious choice for defensive and hunting applications where deep, reliable penetration is non-negotiable. Designed for shooters who demand maximum terminal performance from the venerable .45 Long Colt cartridge, this round bridges the gap between traditional cowboy loads and modern pressure specifications, delivering the velocity and energy needed to defeat intermediate barriers while maintaining shot placement accuracy. Whether deployed in a Ruger Blackhawk, Taurus Judge, or modern lever-action rifle chambered in .45 LC+P, this ammunition serves law enforcement, hunters, and preparedness-minded civilians who refuse compromise on stopping power.

The 250-grain Xtreme Penetrator bullet combines a hardened lead core with a thick copper jacket engineered to resist deformation during penetration, ensuring consistent depth and minimal expansion variability across different target media. By loading to +P pressure specifications—approximately 14,000 PSI versus standard .45 LC's 12,000 PSI—Underwood achieves measurably higher muzzle velocities without sacrificing reliability or creating excessive pressures that risk firearm damage. The 20 rounds per box format allows tactical shooters and hunters to maintain practice ammunition consistency alongside carry loads, while the case pack of ten boxes provides serious shooters with enough volume to maintain proficiency without constant restocking.

This ammunition performs optimally in firearms specifically rated for .45 LC+P pressure levels—notably Ruger revolvers, Taurus Judge configurations, and modern Winchester and Marlin lever-actions marked for +P use. Competitive shooters, backcountry hunters targeting medium to large game, and defensive-minded revolver users will find the consistent ballistics and terminal performance justify the slight velocity increase over standard loads. Always verify your firearm's chamber markings before use; firearms chambered in standard .45 LC only should not fire +P ammunition, as pressure exceedance risks safety hazards.
