Gel test Results
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 -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.
