I am trying to duplicate the WW 28 ga Super Sport load of 3/4 oz @ 1300fps. I can't find anything close to this for the AA. Seems most HV loads are in the Rem SP cases. Any ideas would be greatly appreciated.

I looked at all the data I have, all the domestic powder companies except Accurate and the Lyman and DBI reloading manuals. The best I found was 1275 fps with Hodgdon Longshot.
