My brother left me with an unopened can of Winchester Olin Super-Field AA WSF1 ball powder. I'm guessing its about 10 years old. I can't find any load data for it. He was using WSF1 for 12 guage loads. After massive internet searches I found a picture of the can at some dealer in Australia.

I noticed Winchester does make a powder today called WSF, and I wondered if it was the replacement for the same thing. Its supposed to be good for 9mm, which is what I was going to use it for.

I can't find any load data for WSF behind a 125 grain cast bullet.

If anybody can offer me any info, I would greatly appreciate it.
