Underwood Ammo Handgun Ammunition Features Underwood Ammo builds this .45 Super load around a 255 grain hard cast flat nose bullet a design chosen for its ability to penetrate deeply through bone and muscle on medium to large game. Traveling at 1075 feet per second the bullet generates 654 foot pounds of muzzle energy giving it significantly more power than standard pressure .45 ACP loads while remaining compatible with .45 Super rated handguns. The flat nose profile helps the bullet create a wider wound channel than a traditional round nose design improving terminal performance. This load is rated supersonic delivering its full ballistic performance at the muzzle and downrange. Nickel plated brass casing resists corrosion and tarnishing keeping ammunition reliable even after extended storage in a range bag or hunting pack. The hard cast bullet construction also makes this load safe to use through a suppressor giving shooters flexibility in how they run their .45 Super handgun. Each box contains 20 rounds giving hunters and self defense shooters enough ammunition for practice and carry use. Underwood Ammo s attention to consistent velocity and bullet construction makes this .45 Super load a dependable choice for anyone running this hard hitting cartridge.
