Clay Target

Wuxi Holly`s shooting clay target is an exciting enhancement to clay pigeon shooting.On impact from a high velocity projectile, such as a pellet from a shotgun, the target ignites in order to reflect a direct hit producing a pyrotechnic reaction.The reaction is effective and exciting, resulting in an explosion of white smoke, bright flash and a fairly loud bang.

Our shooting target is produced by new green clay materials, it is green environmental protection, no pollution and could be easily degraded. It could be used in professional shooting competitions.This type is smoking clay target.They're made from a mixture of pitch and pulverized limestone to achieve that calculus of durability and brittleness to break when hit by a few shotshell pellets.There are biodegradable targets that over time dissolve into the soil.
