Ammunition that leaves a visible trail, typically through a burning pyrotechnic composition in the projectile’s base, is generally subject to specific regulations regarding civilian ownership and use. These regulations vary considerably by jurisdiction. For example, such ammunition might be wholly prohibited, require special permits, or be restricted to certain calibers or purposes, such as nighttime predator hunting or specific sporting events.
The legality surrounding this type of ammunition stems from safety and security concerns. The visibility of the projectile’s trajectory increases the risk of accidental fires, especially in dry or wooded areas. Additionally, the inherent nature of visually traceable projectiles raises concerns regarding potential misuse in unlawful activities. Historically, these rounds have played a role in military and law enforcement applications for signaling, target designation, and improving firing accuracy in low-light conditions.
