So guys......I have acquired 4 lbs of an old Winchester powder for which I can find no reference. I know it's a shotgun powder, but like so many shotgun powders I was wondering if it wouldn't have a use in one or more of my pistol cartridges. It is Winchester 540 and with my limited computer skills, I can't even find a burn rate chart that shows it. Nor can I find any load data in any pistol case as far back as I have books.......and that spans more than 40 years.
So is this exclusively a shotgun powder and I should sell it, or can it be used for 45 ACP/38 spl or something like that???????
