Case volume is a concern for me thank you for mentioning it.
I do want spillage with double charge but to be honest no charge worries me more. Until now I have always charged off the press looked in each with a light maybe 50,000 rounds over the past 15/20 years.
Being safe is first
H-6, HP38/W231 will both fit the bill well for you then. Neither one can be double charged in the 9mm, both meter extremely well. This was always my issue with Unique. I could never get it to meter consistently enough to run it near max, and sub-max loads caused issue in my military Browning.
Note these 2 have different applications. H-6 will get you at or near maximum velocity to 124 grain at the expense of slightly dirty burning and more flash. HP-38 will get you good mid-range loads and burn very cleanly, but will not maximize velocity. Pick your poison. Have heard a lot of things about BE86, but I despise Alliants presentation of data. Like they're trying to save bandwidth by not showing the "old" loads which were on their site as recently as last year, and only showing the newer super powders.
