I regularly reload Federal papers with 1-ounce in CB 2100-12 wads (Federal 12SO equivalent) using various powders at about 1170 speed; soft shooting and they work well. Recipes can be found on the powder company websites and in older loading books for the discontinued powders you have. I wonder if WAA12SL wads made for tapered hulls and possibly with with a "filler" for 7/8 ounce will result in powder migration and/or proper gas sealing in straight wall Federal hulls? If not, a bag or two of Federal compatible wads can easily be ordered on-line from several sources.
