I find solo 1000 to meter pretty well, but, if you think finding AA#2 is hard just try finding some solo 1000. It has been missing for years now.
You may want to look at shooters choice clean shot powders, specifically D032. From what I have read it is made in the Czech Republic by Explosia industries and the D032 is based on and may be an earlier version of AA#2. I bought a pound recently to mess around with, it looks just like AA#2 in that it is a super fine ball powder. I haven't loaded much with it yet but did do a handful of .40cal on the way to the range the other day. Didn't chrono, but the loads felt good, were accurate, and they shot very clean.
You wont find a lot of data about this powder online but there are a few people using it and they seem to like it. There is loading data on the shooters world website. Over the next few weeks I will be playing around with it in 9mm and 40 loads and am hoping it works like AA#2 as that is my favorite powder overall but cant find it anywhere.
