The main reason for use of steel shot is environmental, to reduce lead contamination, but steel has inferior ballistic qualities from an energy standpoint less massbut can be partially overcome by increasing powder loads and velocities. This is a hollow point covered with plastic to mimic the profile of an FMJ. Non-penetrating projectiles can also possess stopping power and give support to the energy transfer hypothesis. Rotational forces are in effect that keep the bullet off a straight axis of flight. Different bullets are constructed variously to: These two effects are typically referred to as permanent cavity the track left by the bullet as it penetrates flesh and temporary cavity, which, as the name implies, is the temporary instantaneous displacement caused as the bullet travels through flesh and is many times larger than the actual diameter of the bullet. However, these targets are relatively small and mobile, making them extremely difficult to hit even under optimal circumstances.
