Not sure what you meant - think you were saying " to substitute a Federal wad for the AA wad " and use the load data from Win load. In load data from Federal they use another grain or so of powder for the paper hull. As John said, use the tapered wad in Win and Rem hulls, the straight wad in Fed hulls. Using a tapered wad in a Fed hull will work, but powder can leak by giving you weak or blooper loads. Good luck.
