Incendiary shotgun rounds, often referred to by a colorful moniker, are typically 12-gauge shells loaded with a pyrotechnic composition based on zirconium. Upon firing, these rounds produce a spectacular muzzle flash and propel burning pellets downrange, creating a brief but intense stream of fire. This effect is visually similar to the mythical fire-breathing dragon, hence the colloquial term. One example of this type of ammunition utilizes a plastic shot cup which quickly disintegrates after leaving the barrel, allowing the ignited pellets to spread.
The primary applications for this type of ammunition are in breaching and signaling. The incendiary effect can ignite flammable materials, making it suitable for breaching certain types of doors or obstacles. The bright, visible flash can also be utilized as a short-range signaling device in emergency situations. However, due to inherent safety concerns and specialized applications, civilian access is often restricted, with sales typically limited to military and law enforcement personnel. Its historical context lies within specialized breaching tactics and less-lethal alternatives to traditional breaching methods, though its use remains niche.
