Years ago when I started loading pistol rounds there was a lot of data for Green Dot powder in pistol rounds. Now it seems that Green Dot has almost fallen off the map for reloading handguns. Even Alliant has scant data. The new IMR green has no handgun data that I can find. Is it more due to the plethora of suitable powders? On the other hand, if I had to have just ONE powder for all my reloading needs it would be Unique. There's not many cartridges that one can't use Unique in. I know that most of the data out there for bottleneck cartridges is for cast bullets but it's still using Unique.
