Sounds good. Once you get it figured out and built show us some pictures. With my bread pan idea I figured when I get done shooting I could just empty the brass from the bread pan into a zip lock plastic bag. Usually when I go out I'm taking my 30-06, 8mm Mauser, 30-08 and a couple of SKS's. If your shooting a AR 15, you could always put up a fishing net to the right of you to catch most of your brass.
