agreed. There are so many powders available that new ones come out before I can test ones that I have...If you are looking at powdervalleyinc.com, let me suggest that you get something other than Unique. There are many better powders out there.
for 45acp I recommend looking at one of these:
V340, WW231, power pistol, green dot, HS-6
for 9mm: power pistol, HS-6
