First Use Experience
I tested the Underwood Ammo .45 ACP 135 Grain Solid Monolithic Nickel Plated Brass Cased Pistol Ammunition primarily at an outdoor shooting range, focusing on both accuracy and barrier penetration. I also simulated scenarios involving common barriers found in urban environments, like plywood and auto glass.
