I tried to work up a top-end Miha 9mm 140grn FN load with Accurate 7 (AA7), but accuracy was quite poor, and I just rolled back to Silhouette for the time being. I've decided at this point to go ahead and pay up for whichever appropriate Vihtavuori powder.
What would be the recommended power Vihtavuori for top-end 9x19mm 125grn (Miha HP) and 140grn (Miha FN) boolit loads? N330? N340? N350? (I decided to skip 3N37, for reasons I don't precisely recall.)
I'd appreciate any insight. Right now I'm just using Silhouette, but I'd like more fps if I can get it with accuracy, just because.
