The Defensive Handgun TestTube is a revolutionary new bullet testing medium that provides a Total Understanding of Bullet Expansion. The handgun TUBE has been specifically formulated in Ballistic Blue to illustrate a handgun bullet’s potential for tissue trauma during expansion and penetration. The TUBE is unique in that it is the only commercial bullet testing medium that will permit the wound cavity created by the bullet to be measured in detail to include volume. The Defensive Handgun TestTube will capture the wound cavity created by any bullet commonly used for personal defense. For magnum cartridges two Defensive Handgun TestTubes can be used together.
