MikeJackmin - I've seen big plates with a cutout and a small plate behind ... but never more than two layers. I've seen plain circles with various size bullseye cutouts with plates, I've seen a deer target with a vital area cutout and I've seen a silhouette with the inner section as a cutout. There is a guy at the local gunshows who makes these, I lost his card right after buying myself a steel kitty-cat from him, but he had a LOT of interesting steel targets and the prices seemed reasonable ... check out your local gun shows, you might find your local hobbyist target-maker.
deadin if the plates are mounted right, splash goes down ... and you can tell what you hit by the noise difference
