Any idea?

[mastereagle22]

Found this along with a three ringer and a ball shot at a known CW camp site. It is made of copper or bronze not sure which. There is no hole in the back of it. It has an almost teardrop shape on the side with the holes.

I have a small idea what it might be but would like some input from others....
