I was going through my powder storage area and found a can of Winchester 785 ball powder way in the back. It is still in good shape and I do not like to waste powder of any sort. My problem is is that I do not have any loading data for it only that I know it is slower than Win 760. I would like to use this stuff in loading any of the following cartridges: 6.5X55 Swedish, 30-30, 30-06, 7.5 swiss, 7.62X54r, 303 British, 45-70. Has anyone ever used this stuff with cast bullets and what loading data do you have.
