Very long shot but trying to find a loading manual that list loads with out using the plastic wads of today. Back around 1970 I remembering loading trap loads using fiber, felt, and cork wads. At 75 I don't remember what went first or how thick to use. I' know I need over and under shot cards but not size or thickness. I was using paper hulls at that time. Used them in a double over/under and I think the Browning A5. They were made on an very old MEC. The name and number on the loading manual will work ok, just something to get started.
