I'm using blue duster wads in my gun club hulls for a 1 oz. load. I started using them because I ran out of green duster wads. They work great. My next order of wads is going to be blue dusters and used for 1 oz. and 1 1/8 loads.
The CB clone works great. I've seen no more plastic buildup with them than with DR wads. I get a little build up in the choke tube with every wad I have tried. I like both CB and DR, CB's are usually cheaper so I use them.
