Gel test Results
We tested this Federal Ammunition 357 Magnum ammo by firing five rounds with a S&W 640 with a -inch barrel into calibrated Clear Ballistics gelatin. Of those five rounds, we discovered the ammo penetrated an average of 16.24-inches into the gelatin. Our test rounds ended the test with an average expanded diameter of 0.538-inches, retaining 100% of the projectile's original weight.
