Underwood Ammo Hunting & Self Defense Ammo Features The Underwood Ammo Hunting & Self Defense Ammo load in 9mm Luger uses a gated jacketed hollow point bullet engineered to expand reliably on impact delivering the kind of terminal performance self-defense shooters look for in a carry round. Its 147 grain weight strikes a balance between penetration and expansion making it a versatile choice across a range of personal protection scenarios. A muzzle velocity of 1050 feet per second keeps this load in the subsonic range which also makes it safe and effective for use with a suppressor. The 360 ft lbs of muzzle energy provides solid stopping power without excessive recoil in most 9mm platforms. Loaded in nickel-plated brass cases this ammunition resists corrosion and feeds smoothly through a wide range of semi-automatic pistols. A ballistic coefficient of 0.220 and sectional density of 0.167 contribute to a stable predictable trajectory that shooters can rely on for consistent accuracy. Each box contains 20 loaded rounds giving shooters a practical quantity for range testing or carry rotation. Underwood Ammo built this load for shooters who want dependable suppressor-safe performance in a proven 9mm self-defense round.
