Speer
The Speer Gold Dot 357 Mag 125gr HP is purpose-built personal protection ammunition engineered to perform when it matters most. This 20-round box of 357 Magnum hollow points represents decades of ballistic refinement and real-world testing—ammunition trusted by shooters who demand reliable, predictable performance from their defensive carry rounds.
What sets Gold Dot apart is Speer's exclusive Uni-Cor bonding process, which fuses the bullet jacket to the lead core molecule by molecule during initial construction. This bond virtually eliminates the core-jacket separation that can compromise terminal performance. The 125-grain bullet weight in 357 Magnum is a proven performer in medium-frame revolvers and lever guns, offering a balance of velocity, recoil, and expansion characteristics.
The hollow point cavity itself is engineered in two stages: the first stage determines maximum expansion, while the second controls the rate at which that expansion occurs. This dual-stage design gives Speer engineers precision control over how the bullet performs through different barriers and tissue types. The finished round feeds smoothly in semi-automatic handguns and has been validated against the FBI's rigorous service-class handgun ammunition protocols, which evaluate penetration, expansion, and retained weight through both bare gelatin and common barrier materials.
Whether you carry a revolver or an auto-loading platform in 357 Magnum, Gold Dot ammunition delivers the consistent, barrier-resistant performance that underlies the brand's reputation in law enforcement and civilian defensive shooting.

Yes. Speer finishes each Gold Dot bullet to a smooth profile specifically designed for reliable feeding in semi-automatic handguns, though this load is equally suitable for revolvers and lever-action rifles chambered in 357 Magnum.
The Uni-Cor process bonds the jacket to the lead core at the molecular level during bullet construction. This virtually eliminates core-jacket separation, which means the bullet retains its weight and structural integrity during expansion—critical for consistent terminal performance.
Speer Gold Dot ammunition is validated against the FBI's rigorous service-class handgun ammunition testing protocols, which evaluate penetration, expansion, and retained weight through both bare gelatin and gelatin shielded by common barrier materials.
The 125-grain weight in 357 Magnum is a proven, time-tested load offering a balanced combination of velocity, manageable recoil, and reliable expansion characteristics suitable for a wide range of 357 Magnum handguns and rifles.
