Rubber bullets are rubber or rubber-coated projectiles fired from guns. For this either a riot gun or standard firearms are used. Rubber bullet weapons are "less than lethal devices" but can be dangerous enough to pierce skin. Rubber bullets are non-lethal, when fired at short range and can be used for short range target practice. These bullets are small enough to be fired from a pistol (a rubber bullet pistol) or shot gun. Some other bullets are also made from wood, wax or plastic.
There are various manufacturers, suppliers, wholesalers of rubber bullets who are continuously working to improve bullet performance so as to attract buyers. However, it is also very important to consider various aspects like social and political considerations, health, safety, environmental issues etc.
Rubber bullets cause pain without giving any serious injury. But these may also lead to bone fracture, major injury to internal organ and even death.
