Zirconium-filled shotgun rounds produce a spectacular visual effect upon firing, projecting a fiery jet of sparks and burning particles several feet downrange. This effect results from the ignition of the finely divided zirconium upon exposure to air and the propellant’s heat. These rounds are typically loaded into 12-gauge shotgun shells and function similarly to other shotgun ammunition, relying on the burning propellant to propel the payload forward.
While often associated with entertainment or visual displays, this pyrotechnic ammunition has seen limited practical application in certain scenarios. The incendiary nature of the zirconium payload offers potential use for clearing vegetation or igniting flammable materials at a distance. Historically, similar concepts have been explored for signaling or illumination purposes. However, it is crucial to acknowledge the significant safety concerns associated with its use, given the inherent fire hazard.
