Speer 158 Grain Jacketed Hollow-Point (JHP) Ammo Details

This is .357 Mag Speer Gold Dot 158gr. Hollow Point Ammo. This is the Gold Dot ammo that is sold to many Law Enforcement agencies. Speer Gold Dot Handgun Cartridges Uni-Cor construction virtually eliminates core/jacket separation, the main reason for bullet failure with conventional cup and core bullets. A patented process forms the hollow point cavity in two stages. The core is pre-fluted to define the "fault" lines of expansion, controlling final diameter and retained weight. The second process finishes the cavity and controls the rate of expansion. Clean burning propellants deliver optimum velocity while ensuring consistent chamber pressures. This ammo is packed in 20rd. boxes.

Ballistic Gel Testing

 

In hopes of giving ourselves and our customers a better idea how this 357 Magnum self-defense ammo would perform if called upon in a self-defense scenario, we tested dozens of the best selling hollow points on the market.

We fired five rounds of this Speer 357 Magnum ammo through a cloth barrier into Clear Ballistics calibrated synthetic gelatin and recorded the results. For these tests, we used a S&W 640 with a 2.125-inch barrel. In the photos, graphics and video on this page, you can see specifically how the Speer ammo performed and how it sticks up with the rest of the 357 Magnum ammo we have tested so far.
