Thank's all. Gives me a place to start my investigations. Matt, the 16 grain Unique load look's promising. How do you find the WAA20 wad for a fit in the Cheddite hull? Have you done any loads using 3/4 oz. shot? 3/4 oz. in a 16 or 12 break clays nicely and should perform well in a 20 as well. 7/8's was chosen for a field load and a target load. 3/4 may make a better target load. My RST flats just came in and I'll have the winter to set up for reloads.
