I have been able to buy quite a bit of older powders lately...and need some data for some of it. When I moved quite a few years ago I got rid of all extraneous paper work so no longer have my old stuff. Need help with mostly Winchester powders. I got 5 lbs Win 230P as well as 4 lbs of 630 6 lbs of 680 and 12 lbs of WAA 12S I think it is called..all for a buck a pound. Had to pay a bit more for the Unique and Herco but still pretty cheap.So if anyone has some old data for the Older Winchester powders or can direct me to some..I would certainly appreciate it.
