N320, N330, and N340 will all work great in 9MM. N320 for lighter loads, N330 for all around good performance, N340 to get a bit more, and then 3n37 to make it really go. If I remember from your posts, Vihtavuori is one of the few powders you can get there. Good stuff though. pricier here than other powders, but not bad if you buy in bulk. I like it in a couple of loads were I have not found a cheaper powder that works as well. It meters very well, doesn't stick in measures, is accurate, super clean, and just hard to beat in some applications.
I just started playing more with 124 gr bullets in 9MM, so I don't have any specific loads to share.
