Underwood .45 Long Colt 250 Grain Extreme Penetrator Solid Copper – 20 Rounds (Box) 838

Built for shooters who demand maximum penetration and uncompromising terminal performance, the Underwood .45 Long Colt 250 Grain Extreme Penetrator Solid Copper ammunition delivers serious stopping power in a legendary revolver cartridge. Loaded with Lehigh Defense’s advanced Extreme Penetrator projectile, this premium defensive and hunting load transforms the classic .45 Colt into a modern hard-hitting powerhouse designed for deep penetration, barrier performance, and devastating wound channels.

The Underwood Ammo 838 load features a 250 grain solid copper Extreme Penetrator projectile engineered for extreme terminal effectiveness without relying on traditional hollow-point expansion. Instead of mushrooming, the patented fluted bullet nose redirects hydraulic force outward during impact, creating massive fluid displacement and a larger permanent wound cavity while maintaining deep, straight-line penetration. This innovative design offers the reliability of a non-expanding bullet combined with terminal performance that rivals many expanding projectiles.

Unlike conventional lead-core bullets, the solid copper construction helps the projectile retain virtually all of its weight after impact. This makes the Underwood Extreme Penetrator an outstanding choice for defense against dangerous game, backcountry protection, hunting applications, or personal defense where penetration through heavy clothing, bone, or intermediate barriers may be required. The CNC-machined copper bullet also eliminates concerns associated with jacket separation or fragmentation.

Velocity is one of the biggest advantages of this load. The Underwood .45 Long Colt 250 Grain Extreme Penetrator produces an advertised muzzle velocity of approximately 1,000 feet per second with muzzle energy around 555 foot-pounds, delivering impressive energy from revolvers and lever-action rifles chambered in .45 Colt.

• Bullet Weight: 250 Grain

Underwood Ammo is known for loading ammunition to the upper end of safe performance specifications while maintaining exceptional quality control standards. Each cartridge is loaded in premium nickel-plated brass cases for improved feeding reliability, enhanced corrosion resistance, and easier extraction. The nickel-plated cases also resist moisture and tarnishing during long-term storage, making this ammunition an excellent option for carry guns, emergency kits, or outdoor use in harsh environments.

Another advantage of this load is its subsonic velocity profile. At approximately 1,000 FPS, the round remains below the speed of sound in most conditions, reducing sonic crack while maintaining substantial impact energy. This can help improve shooting comfort while still delivering the hard-hitting penetration .45 Colt shooters expect.

The Underwood 838 Extreme Penetrator is ideal for modern revolvers such as the Ruger Blackhawk, Ruger Redhawk, Taurus Judge, Smith & Wesson Governor, and lever-action rifles chambered in .45 Colt. Hunters and outdoorsmen especially appreciate this load for protection against hogs, black bears, and other tough-skinned game where penetration matters more than expansion.

For shooters searching for premium .45 Long Colt hunting ammo, hard-cast alternative defensive ammunition, or deep-penetrating revolver loads, the Underwood 250 Grain Extreme Penetrator stands out as one of the most innovative and effective .45 Colt loads available today.

This is not old-school cowboy ammo drifting through history books. This is modern .45 Colt performance with copper teeth and a freight-train attitude. 🔥
