Targets used in clay pigeon shooting sports are typically composed of a mixture of natural materials. This commonly includes limestone or other calcium carbonate sources, combined with pitch and other binding agents. The precise composition can vary depending on the manufacturer and the intended use of the target, leading to variations in hardness, flight characteristics, and visibility.
The composition of these targets is carefully engineered to provide several key benefits. Their brittle nature ensures they shatter visibly upon impact, providing clear feedback to the shooter. The materials used are also designed to minimize environmental impact, breaking down into relatively harmless components after being fired upon. Historically, live pigeons were used in this sport; the development of clay targets marked a significant ethical and practical advancement.
