I load the Federal purple shells with a Winchester 209, American Select, the DR-16 wad and 7/8 ounce of shot. Great clay target load. I load the old compression formed Winchester/Western hulls with a Winchester 209, 20.5 grains of WSF, the Clay Buster clone of the old WAA-16 wad and 1 ounce of shot. This is the load that had the asteric in the Winchester Ball Powder loading guide saying it duplicated the factory load.
