But eco-friendliness isn’t the reason why Underwood loaded this 40 S&W cartridge with the solid-copper Xtreme Penetrator – a bullet that just so happens to be extremely effective at the application it’s named after!
This round’s light bullet cruises out of a 4” barrel at supersonic velocity, granting it higher-than-normal close-range striking power. The CNC machined bullet’s monolithic construction prevents it from splintering apart during high-velocity impact with barriers and target alike. And once the bullet’s nose flutes bore into soft tissue, they begin pressurizing and blasting it outward in a devastating exhibition of hydraulic force.
The Xtreme Penetrator sports a smooth-feeding nose profile, and its lubricious nickel-plated brass cases only promote even better operation in a semi-automatic. If you ever have to defend yourself in endangered eagle habitat after dark, then you’ll appreciate Underwood’s non-blinding low-flash powder.
