20rds – 40 S&W Underwood 140gr. Xtreme Penetrator Ammo

Underwood Ammo 140 Grain Solid Copper Ammo Details

Don’t forfeit any peace of mind by chambering subpar self-defense ammo. If you’re carrying a forty, keep Underwood in its mag.

It was Lehigh Defense that made this round’s state-of-the-art bullet, though. Monolithic. Zero lead. All copper. Precision machined to supply buttery smooth feeding, and unable to deposit gray fouling in the bore. It’s the Xtreme Penetrator, which lives up to its name courtesy of its durable composition and unique Phillips head screwdriver-like nose profile.

The non-expanding Xtreme Penetrator doesn’t just penetrate up to twice as deep as a traditional expanding bullet. Its blunt nose delivers traumatic impact energy, and its unique fluted channels pressurize surrounding soft tissue to stir up a jarring energy spike accompanied by a wide-diameter permanent wound cavity.

Underwood’s nickel-plated cases resist tarnishing when exposed to moisture, leather, and other metals. They also minimize friction to facilitate cycling. The Illinois manufacturer’s low-flash propellant produces less blinding light during nighttime ignition – just one of many advantages to be gained by selecting this self-defense ammo (which ought to work just fine on black bears if you aim it right).
