For Minor I I would think you would like to be around 130PF. You might what a hair more to be safe, AA7 might work but is to slow IMO for a minor load. ( 9mm or .38 Super?)) But it might shoot great in your gun.
I think you would be better off with a faster powder for minor, something around N320 or Sport pistols speed.
If you look at the USPSA nationals survey you can see what most people are using. Titegroup, N320 and Sport pistol seem to be popular.
(of course everyone has their own likes and dislikes)
If it is in 9mm Western data shows
Start charge, start vel, Max charge, Max Vel
So it might be doable with AA7
115@1100=126 PF
If it was me looking for a minor load would be looking to use a heavier bullet and keep it subsonic.
As opposed to major when shooting minor you want to try to keep the recoil as low as possible which is heavier bullets with the least amount of powder to do the job.
I have tried 147s but my gun just prefers 124s so I have more recoil than if I was using a 147 since I have to have around 1040 with a 124. (128 PF)
Maybe
@waktasz will see this and comment he is a much better shooter in than I will ever be so his opinion might hold more weight than mine.
