So it is that time again! I can't believe it; every ten years I get my hands on some (love the A series), and then spend the following nine cursing the French for sucking at exports...
I would buy AS and A1 at a slightly better price. They don't meter well with the first three (small) cavities of the LEE Auto-Disk but the other disks are fine.
These powders are very fluffy and the A1 didn't suit cases smaller than the 9 Luger with my equipment. I found them cleaner than the average US made lot, on par with 700X maybe.
The A1 is the best powder I know for beginners: fluffy, highly visible (light green) and very similar to Unique in use; the A0 might even be better but I didn't see a use for the burning rate at the time (this is the powder they use for cast bullets and reduced loads in rifles).
AS is a very good choice for savvy shooters (plinking or target with 9, 44, 45's; I preferred A1 in .38).
The Ba series meter very well.
The Ba9 is an other Unique twin, but my last jug lost its mojo; a problem which was reported by an other shooter somewhere on the web.
The Ba10 had a very unpleasant smell and was, if I remember, dirty compared to the others; but since I was the only one to complain about it you can probably dismiss the comments; it is similar to Bullseye in use (Match!).
I would try the new 9 1/2 since it is similar to 700X in burning rate.
The Prima and other cute names are a mystery to me. They don't fit in the regular SNPE/Vectan lines and don't figure on the French website. Even their shape/construction is different.
