Speer Gold Dot ammunition's reliability has made it the No. 1 choice for law enforcement, and now the same performance is available for self-defense rifle applications. Gold Dot Short Barrel rifle is engineered to provide industry-leading performance in FBI protocol testing through barrels less than 16 inches long. Its bullets are built using Speer's exclusive Uni-Cor method. The jacket is bonded to the core one atom at a time, virtually eliminating core-jacket separation and creating a projectile that's accurate, tough and consistent through all common barriers. This ammunition is new production, non-corrosive, in boxer primed, reloadable nickel plated brass cases.
