Abstract
A collapsible training projectile includes a nose, a body and a tail. The dy has a forwardmost end secured to the nose, and a rearwardmost end secured to the tail. The body further includes one or more axial, longitudinal slots that extend radially through at least part of the body, such that when the projectile impacts with an object, the kinetic energy causes the body to plastically deform along the slots, thereby reducing the penetration energy of the projectile. In another embodiment, the projectile includes a wedge, a body and a tail. The forwardmost end of the body is secured to the wedge, and its rearwardmost end is secured to the tail. The body includes an axial hole which is formed along the axial center of the body, and which extends from approximately the rearward tip of the wedge to the rearwardmost end of the body, such that when the projectile impacts with an object, the kinetic energy drives the rearward tip of the wedge partially through the axial hole, causing the forwardmost end of the body to plastically deform and to sheer around the wedge.
