Ballistic Gel Testing
We tested this Federal Ammunition 357 Magnum ammo by firing five rounds with a S&W 640 with a 2.125-inch barrel into calibrated Clear Ballistics gelatin. Of those five rounds, we discovered the ammo penetrated an average of 20.58-inches into the gelatin. Our test rounds ended the test with an average expanded diameter of 0.52-inches, retaining 99% of the projectile's original weight.
On this page, you'll see video of our tests including photographs that detail the ammunition before/after firing it through a four-layer barrier into gelatin. Also, you'll see how this Federal Ammunition 357 Magnum ammunition stacks up compared to other self-defense rounds in 357 Magnum.
