Since I dont have the time or finances to shoot registered skeet events any longer, I find myself with a lot of once fired AA and STS 12 ga and 20 ga hulls. I was thinking about using the load that is identical to the AA low velocity -low noise load except without lead shot...does anyone have any suggestions for what materials to use to in place of the lead, only needs to be about 3/4 to 7/8 of an ounce at the most
