I want to load some 125grain winchester HP's for my bolt action .357 rifle. I would like to use some AA#7 that I have on hand but I am getting confusing load data. My Speer book says 12.0g - 13.5g but Accurate's website shows
10.9g - 12.1g Both show the same OAL. My lyman book does not show this powder for this bullet weight. Does anyone have any experience with this powder for .357 Thanks for the help...
