I have been losding this load for a few months. I find that I have to put a cork spacer under the shot to get a crimp that doesn't crater. Loading number 9 shot I put a thin over shot card as well. The eight point crimp works well when you get the cam adjusted and they make some nice looking loads.
Claybuster makes a replacement wad for the Winchester wad.
The Hogden manual also gives about the same recipe for the WinAA hull. I have found that with the newer hulls the side walls buckle. The old WinAA hulls, both red and silver do just fine though.
