For years I loaded 1 ounce loads using the Winchester/Western compression formed hulls, the WAA-16 wad, WSF powder (from memory I think I use 20.5 grains, but I'm travelling and away from my data) and the Winchester 209 primer. Then Winchester quit making the WAA-16 wad, but just about the time I ran out of my supply, along comes the CB-16 wad, so my hoard of compression formed hulls are still in business. For the last year and a half I've been loading the purple Federal hulls with a Winchester 209 primer, American Select powder, and 7/8 ounce of shot in the DR-16 wad. I've been amazed how well these Federal hulls stand up. After loading all the hulls I had boxes for, I had about 60 extra hulls, so I started loading and shooting those hulls over and over. At ten reloads I still had thirty some hulls.
