This is what I did many years ago, before the companies discussed above were available. Used them to shoot clays, and 10ga bismuth loads when hunting waterfowl.

Klunkermeister(Russ Ruppel) gave me the idea and then had a thread about making them posted here. Archives don't back to that far, so I'll post up the pictures again. Actually kind of amazed that I still have the pictures hosted.
