You can sanity-check AA#7 data by comparing it to a similar load using Blue Dot. They should be about the same, with the #7 using just a little more powder.
#7 is not a very good choice for .38 Special; it works a lot better in .357 Magnum. It should be usable with the heavier bullets -- but it will take twice as much powder as something more appropriate, and you'll get lots of unburned powder.
I think you'd be a lot happier with Bullseye.
