A Dragon's Breath usually refers to a zirconium-based pyrotechnic shotgun round. When the round is fired, sparks and occasionally flames shoot out to about 15 m (48 feet), beyond 15 metres, the round's already limited effectiveness is drastically reduced.[1]
While its tactical uses are very limited, the visual effect it produces is impressive, similar to that of a short-ranged flamethrower. The rounds are often used as a distress signal, similar to an emergency flare gun. They can also be used as means of intimidation to the opposing forces. The pyrotechnic shell is expensive compared to other shells, costing around 5 US dollars per shell. Although there is little to no record of its use in actual combat, Dragon's Breath can be considered an anti-personnel round. However, the potential damage it can cause on an enemy combatant can be considered inhumane.
Because it is a very low-power round, it cannot be used in an automatic shotgun; it does not produce enough recoil energy to cycle the next shot, causing the mechanism to jam. An additional reason for use only in a manually-operated firearm is the fact that the round shoots at least a little flame for 3–5 seconds. This would cause a hazard if a shell still emitting flame were to be ejected from an automatic shotgun.
Dragon's Breath rounds are banned in many locations, due to their inherent fire hazard. Even in areas where the round may be shipped, an extra fee for hazardous materials may be charged.[2]
The law in the State of Illinois states that a Dragon's Breath round is any round that "contains exothermic pyrophoric misch metal as the projectile and is designed for the purpose of throwing or spewing a flame or fireball to simulate a flame-thrower".[3] This shotgun round is banned for use by anyone who is not authorized to possess, manufacture, or sell by the law." The wording is very similar for Florida as well.[4]
