Dragon's breath is a special type of incendiary-effect round for shotguns. Dragon's breath consists primarily of magnesium pellets/shards. When the round is fired, sparks and flames can shoot out to about 100 feet (30 meters), although, some sources claim it extends to 300 feet (91 meters).^[1] Dragon's breath is normally chambered in 12-gauge 2+3⁄4″ (18.5 mm × 69.9 mm) shot shells. The rounds are safe to fire out of an improved cylinder bore as well as a modified choke barrel, common on many shotguns.^[2]

While its combat or tactical usage remains undocumented, the visual effect it produces is impressive and entertaining, similar to that of a short-ranged flamethrower or fireworks.^[3] Some enthusiasts claim that the rounds are often used as a distress signal, similar to a very short duration emergency flare gun.^{[citation needed]} The safety aspects of the ammunition are disputed, as the magnesium shards burn at approximately 3,000 to 4,000 °F (1,650 to 2,200 °C), which is more than enough to light a person, or house, on fire.^[1][4]

The sale of Dragon's breath rounds is illegal in several states (Alaska, California, District of Columbia, Florida, Hawaii, Illinois, Iowa, Massachusetts, Maryland, and New York) and shipping may be restricted in other locations and cities due to their inherent fire hazard.^[5]
