I was given a couple pounds of 452AA in the original container recently. Years ago I used it for shotshells but I disremember what the load or gauge was. Seems like I was loading a lot of 16's and 12's back then. I have misplaced my old Lyman manual with load data for that powder. I believe 452AA and the old Hodgdon Trap 100 were interchangeable. I have an old Hodgdon manual with Trap 100 data in it. Anybody else got a source of data for 452AA in 12, 16, or 20 ga? I also got a recolection of about 5 grains of 452AA in the 9 mm.
