I have a near lifetime supply of both the old Winchester compression formed hulls and the black Remington Game Load hulls. Right now I'm loading the Remington hulls, using the old blue Remington 1-1/8 ounce wads with a 1/8 inch card filler and 7/8 ounce of shot. I happen to be using Universal powder because that's what I had on hand.
Some of the older Lyman manuals should have data for Superfield and AA473 if they were tested and used for 16 gauge loading. If you cannot find one of them, send me a PM with an email or cell phone number and I'll scan the pages in. I have a number of the older Lyman manuals dating back to the 1960s.
