You seem to be intent on using a fairly slow powder for your 9mm range ammo. When I build JHP ammo for the 9mm I use Longshot which is in the same burn rate range as AA#7 but when making range ammo I don't go nearly as slow with powder choice. If you like Accurate powders I would think AA#5 would be a better choice for the 9mm than AA#7 for range ammo, but that's just me...
