You may find that the AA7 doesn't burn as well at the lighter, like other powders like to be near the upper pressure range to perform and burn cleanly.

But I will welcome the data you observe and share also. So good luck!

BTW I just loaded some 9X25 Dillons with 121gr. JHP's over some AA7 tonight...these will get tested from the S&W1006 and the Glock 29 both stock length barrels for each.
