Not to be mistaken for BA9+. This is somewhat like AA#5, Unique but slower than VV N330. Its also in the ballpark with Winchester 572. It might be similar to VV N340 also.
Very short stick powder. Like some VV powders in stick comparison, such as 3N37, however its faster burning than that.
This has load data from Nobel Sport for 9 MM. Not much data at all, but it gave us an idea where to start.
I would fathom to guess, 5.5 using the bullet we used, which would be similar to a Rainier 115 grain (long bullet) is near max. Very close to max. If we were going to guess, max here would be about 5.6 or 5.7 perhaps. Its actually pretty close to Nobel Sport Vectan A0, but a little faster burning. Perhaps its about .3 to .5 grains away in charges "less" than A0, if I was going to guess, for around a 115 grain bullet. Just guessing, but you, never guess, consult manufacturer, load at your own risk.
