I have that same loading data from Lee & I believe that is for card wads.
I have the Lyman manual #1 (very old) at home & could look later today when I get home but I believe there is data in there using the red AA wad or the SP12 Remington for plastic hulls (AA) - AL 5 & the above wads. I used that stuff years ago for a 1 1/4 oz. loads for waterfowl. I still have some of the Al5 left over & it still shoots just fine. Colonel
I loaded AL5 and AL7 for years. I loaded 31grs. of AL5 a #1 ALCAN wad 1 1/4 oz. of 6's with 220 MAX-FIRE primer.ALCAN POWER HAS TO HAVE 65lbs OR MORE WAD PRESSURE or you will get a flame thrower. 35grs of AL7 same as above. HENRY
