i was recently at a department of wild life management fundraiser and they had clay shooting. on the trap range, the clays had a small puck that was glued into them and when you hit the clay, a puff of powder was sent into the air. any one know where to get these or something like it?
What you want is known as a "Flash Target" White Flyer describes them as:
Flash targets are found in the 110 mm configuration and are specifically prepared with a pouch of fluorescent colored powder underneath or on top of the dome. The flash target explodes on impact and provides a puff of colored smoke to show the "kill" more clearly. These targets are used for the final events in International competitions and for televised events.
White Flyer targets are distributed in the US and Canada.
