AA7 is a slow powder with a similar burn rate to Blue Dot. I have loaded some 9mm with 8.0grs of #7 behind a 115 gr Remington JHP. They chrono'd at 1,163 fps average from my Glock 19 which is a relatively moderate velocity for a 9mm. They did have a consistent STDEV at 9.24 fps which in my experience anything 12 fps or less is quite good.
The advantage of a slow burning powder is that you can get higher velocities at lower maximum pressures. AA7 was developed by the Israelis for use in their SMG 9mm ammo. I would guess you will get a sub 1,000 fps load with a 6.8gr load behind a 115gr bullet. The Speer 115 gr Gold Dot is an excellent defense bullet used by many police departments. Speers standard pressure load has a MV of around 1,220 fps. For the cost of gold dots you would be better served with a defense level load closer to the factory velocity and reserve light sub 1000 fps loads for less expensive cast or plated bullets for punching holes in paper targets.
