I'm not sure how useful this is, but I happen to have several obsolete powders that I use, or will eventually use. I have them because they were either given to me or they were very cheap, and I figured it was worth trying to make them work. And it's very tempting when stuff is in short supply.
What I have learned so far:
HS-5
Works great in 9mm. Have not used it for anything else.
5.2gr with a 124gr plated bullet is very accurate. Clocks in at ~900 fps.
5.7gr with a 115 plated bullet clocks at 1070fps. Not quite as accurate for me.
Hi-Skor Shotshell
Does NOT work in 9mm. I had one load that was accurate, but would not cycle anything. A 4.0gr load does cycle and very nearly fills the case. Couldn't get any accuracy out of anything more - maxed out at 4.4gr and that was probably slightly compressed with 115gr plated.
Powders I have yet to try Win 450LS, Alcan AL-120.
I also have 1/2lb of Win540, but found out here that is the same as HS-6.
