Stay with published load data like digger said. I find myself using mostly Hodgdon powders for shot cartridges, so I get my data off their web site. That said, Clays is my go-to powder for target loads.
I gotta ask, why 1 1/8oz. loads for quail, doves, and clays? Drop down to 1oz. and kill just as much stuff, plus then with 1/8oz. less shot, every eighth shot charge is free so to speak. Better yet, try 7/8oz.- trust me when I tell you the birds won't know the difference. With shot so damned expensive, lighter loads make even more sense. Personally I don't know any trap/skeet/clays/dove shooters anymore who shoot 1 1/8oz. loads, myself included.
