This box of Speer Gold Dot .357 Magnum 158gr 20 rounds (Speer part no. 23960GD) is a self-defense revolver load from Speer, built around the Gold Dot hollow point that has earned the trust of law enforcement worldwide. Speer rates it at 1235 fps with 535 ft-lb of muzzle energy from a 4-inch vented test barrel. The bullet is bonded to its jacket with Uni-Cor technology, which Speer says virtually eliminates separation on impact so the bullet keeps more weight and penetrates to crucial depths. Nickel-plated brass and a sealed primer round out a load made for personal protection and duty use.
