First Use Experience

I tested the Underwood Ammo .40 S&W 140 Grain Xtreme Penetrator Solid Monolithic Nickel Plated Brass Cased Pistol Ammunition
829 43% Off at an outdoor shooting range under typical late-spring conditions, with temperatures hovering around 70 degrees Fahrenheit and moderate humidity.
