I like the following, which I gathered from this site:
1 1/8 oz. - 19 grains of Red Dot
1 1/4 oz. - 27 grains of Green Dot
1 3/8 oz. - 24 grains of Unique
Lead or bismuth.
All use a Remington hull cut to size (Chedites also work), Winchester 209 primer, SP-10 wad, and a 16 gauge fiber filler wad (about 1/4 inch) in the cup under the shot.
The last one was tested (
