I'm going to suggest that you're doing this backward.
- What do I want to do with this gun?
- What bullet would be most appropriate for that?
- In what velocity range do I want that bullet moving?
- What powder would be appropriate to move that bullet into that velocity range?

Welcome aboard !ID is right if you were actually planning this out, but it sounds like a pile of powder landed in your lap and now you got to use it up. I certainly would !
Noylj is also correct, for all intensive purposes 175gr is 180gr. It would be better if the data was for a 185gr and you were shooting the lighter 180gr, but it will work. Just don't shoot the Max Load.
In 9mm I found HS-6 to be extremely accurate, but a bit on the smudgy/dirty side. Like 'clean the gun after every range trip' type dirty.... and I never do that !
Hope this helps.
