This rubber projectile is not quite 2 inches in length and is 12-gauge in diameter. It weighs 0.2 ounces and has a maximum range of 250 feet when fired from a 12-gauge shotgun. The stabilizing fin makes it more accurate, although if it bounces off a hard surface, it can tumble or spin, making its' trajectory and effect largely unpredictable.

This round is effective for the dispersion of crowds, the disbursement of individuals in crowd control or civil disturbance situations. It can be effective against subjects who offer violent resistance.

When striking an individual, its relatively low velocity, large surface area, and rubber composition make it less likely to penetrate. Its effects are primarily to stun the individual and cause sufficient pain to cause them to withdraw or discontinue their violent resistance. 

At the extreme effective range of 100 feet, the effects on the individual may be nearly trivial. At closer range, bruising can be seen. Rib fractures are possible if the chest is struck. At extremely close ranges of less than 20 feet, the projectile may penetrate the body, leading to fatal wounds.

The effects of this projectile striking the head are variable, but can be fatal, just like any violent blow to the head.
