I’m about to acquire 30 pounds of an old Winchester powder, and I’m looking for load data. This is Winchester 473AA. I generally shoot number eight shot at about 1150 FPS. 12ga, 1 ounce loads.
Thanks

I don't think Win 473AA is a good choice for 12 ga. 1 oz loads. But it's fine for 1-1/8 oz. I actually just dug out an old canister and loaded a case of shells today. Win AA case, Cheddite primer with 23.5 grns of 473AA, Claybuster WAA12 clone wad and 1-1/8 oz - 1200 fps 8500 LUP. Load data is from Winchester manual with Cheddite primer substituted for Win 209
