Ballistic Gel Testing
We tested this Fiocchi 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 20.82-inches into the gelatin. Our test rounds ended the test with an average expanded diameter of 0.478-inches, retaining 100% 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 Fiocchi Ammunition 357 Magnum ammunition stacks up compared to other self-defense rounds in 357 Magnum.

This ammo cycles my new Coonan .357 Auto with no problems. The heavy Bullet proving enough recoil energy with new spring to push the slide all the way back ton cycle another round into battery. Once you go .357 Auto like the Coonan you enjoy the recoil. As they say This is not your first gun! Good price too.

Purchased 500 rounds a few years back, no misfires, no issues, consistent round. highly recommend this product. Was just returning to reorder from ammo to go and realized that I had not provided any feedback. Good value for good ammo.
