Underwood Ammo ASP Features The Underwood Ammo ASP load is built on Nosler s Assured Stopping Power bullet platform using deep skives cut into the jacket mouth to control how the bullet opens on impact. This design broadens the range of applications the bullet can handle without sacrificing the accuracy and feeding reliability a shooter depends on. At 185 grains and 1300 feet per second the bullet generates 694 ft lbs of muzzle energy a combination that supports both personal defense and hunting use. A ballistic coefficient of 0.142 and a sectional density of roughly 0.13 give the bullet a stable flight path paired with solid penetration characteristics. Each cartridge uses a nickel-plated brass casing which resists tarnishing and corrosion far better than traditional brass when exposed to moisture leather or other metals during storage. The nickel plating also improves feeding reliability across a variety of actions and makes case cleanup easier for anyone who reloads. This load is rated safe for use in a suppressor giving shooters flexibility in how they run their .45 Super platform. Packaged 20 rounds to a box the Underwood Ammo ASP is a dependable choice for shooters who want proven stopping power for sale at GrabAGun.
