Speer Gold Dot Personal Protection bullets utilize a specialized Uni-Cor process where the copper jacket is electrochemically bonded to the lead core. This molecular bond ensures the projectile maintains its structural integrity and retains nearly all its original weight, even when encountering tough obstacles. The hollow point cavity is precision-formed to initiate immediate and consistent expansion, creating a wide, permanent wound channel. Engineered for absolute reliability, these 115-grain projectiles provide handloaders with a high-performance component that delivers professional-grade accuracy and devastating terminal energy.
