When Does A Bullet Become Lethal ???

This video from Kentucky Ballistics, featuring Scott, explores the minimum velocity required for a 9mm bullet to achieve lethal effect. Using a Ballistic Dummy Lab torso and a ProChrono DLX chronograph, the experiment systematically tests various 9mm loads fired from pistols with different barrel lengths. The results demonstrate a clear correlation between velocity and penetration, culminating in a dramatic test of a 4-gauge shotgun.

Quick Summary

The minimum velocity for a 9mm bullet to achieve lethal potential, demonstrated by penetrating the chest cavity of a ballistic dummy, was observed around 509 fps. Lower velocities, such as 165-328 fps from very short barrels, proved insufficient for significant penetration or incapacitation.

Frequently Asked Questions

What is the minimum velocity for a 9mm bullet to be considered lethal?

Based on the Kentucky Ballistics experiment, a 9mm bullet began showing lethal potential around 509 fps, penetrating the chest cavity. Velocities below 328 fps were insufficient for significant penetration, even failing to pass through a rib.

How does barrel length affect bullet velocity and lethality?

Shorter barrels significantly reduce bullet velocity. The experiment showed that a 1.25-inch barrel produced very low velocities, while longer barrels increased velocity, leading to greater penetration and lethality.

What ammunition types were tested for lethality?

The test included standard 9mm rounds fired from short barrels and specifically Underwood 147gr Jacketed Hollow Point (JHP) 9mm ammunition. A Russian 4-gauge shotgun with various loads, including a 1000-grain slug, was also tested.

What equipment was used to measure bullet performance?

A Ballistic Dummy Lab zombie torso was used to simulate human tissue and bone. A ProChrono DLX chronograph measured the precise velocity of each projectile in feet per second (fps).
