I have some Winchester 452AA Ball Powder that's probably at least 30 years old. Does anyone have any recipe for it for 12 ga? I can't seem to find much in this one. Was it replaced by something better? Can I use it for anything else I have (.357, 32acp, 8mm, 303 brit, nagant, Ithica 12 ga)? I read somewhere that it was terrible to use in 38/357. I guess my primary question would be regarding the 12 ga though.
