Ballistic Gel Testing
We tested this Speer 40 Smith & Wesson ammo by firing five rounds with a S&W M&P40c with a 3.5-inch barrel into calibrated Clear Ballistics gelatin. Of those five rounds, we discovered the ammo penetrated an average of 15.88-inches into the gelatin. Our test rounds ended the test with an average expanded diameter of 0.618-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 Speer 40 Smith & Wesson ammunition stacks up compared to other self-defense rounds in 40 Smith & Wesson.
