  • Environmentally safe projectable targets
    Patent number: 6428007
    Abstract: A shooting activity and a clay target which can be formed without pitch for use in such activity is provided. The activity involves shooting shot at the target and breaking targets hit by the shot. The target can be formed with a binder and filler and cast into a strong yet brittle state. Targets in accordance with the invention should be substantially pitch free and have a high LD 50 toxicity level as well as high frangibility. This can be accomplished in accordance with the invention by forming the targets with high internal stresses such as are formed by forming targets in unstable crystal states.
    Type: Grant
