Underwood Ammo ASP Features The Underwood Ammo ASP .460 Rowland load is built around the Nosler Assured Stopping Power projectile a 230 grain jacketed hollow point featuring deep skives in the jacket mouth that promote rapid consistent expansion on impact. These precise reliefs allow the bullet to expand reliably without sacrificing feeding reliability or accuracy assuring strong energy transfer while limiting the likelihood of over-penetration. At a muzzle velocity of 1400 fps the load generates 1001 ft lbs of muzzle energy delivering serious stopping power for personal defense and hunting applications. This ammunition is rated supersonic and is safe to use with a suppressor equipped .460 Rowland pistol. Nickel plated brass casings provide several practical benefits over standard brass including improved feeding across a variety of firearm actions and enhanced resistance to corrosion during long term storage. The nickel finish also resists tarnishing when in contact with leather moisture and other metals keeping the ammunition looking clean and ready to use. Each box contains 20 rounds giving shooters enough supply for range sessions or carrying as a dedicated defense load. Underwood Ammo manufactures every round with a focus on consistency and performance for serious handgun shooters.
