The Xtreme Penetrator bullet by Lehigh Defense is not a hollow point, nor is it a soft point. So how does this 10mm cartridge by Underwood of Illinois create such a wide and devastating wound cavity? The answer – is science.

This round’s 140 grain bullet is 100% copper: no lead that could pollute the environment, contaminate a quarry’s meat or foul a firearm’s rifling. The monolithic Xtreme Penetrator is also tough enough to pass through thick fabric, rugged hide and urban barriers without losing a significant portion of its weight. That means reliably deep penetration!

The Xtreme Penetrator’s tip is shaped like a plus sign, and long tear-shaped grooves are machined into its shank. These grooves scoop up whichever soft tissues they come into contact with, pressurize them, and then jet them outward at a higher velocity than the bullet itself is traveling. The end result is a gaping permanent wound cavity that can drop an attacker or game animal in an instant.

Worried about blinding muzzle flash compromising your accuracy at night? Don’t be. This 10mm load’s low-flash powder doesn’t burn bright enough to throw your eyes out of night vision mode. Underwood’s nickel-plated cases lessen friction to promote smoother functionality in semi-auto firearms, and they also resist corrosion from atmospheric moisture.
