I thought it odd that you'd select AA#7 rather than AA#2 (which is on my wish list), so I checked my Hornady powder comparison list [pic below]...
I presently use Red Dot. I have most of a can of Blue Dot (similar to your AA#7) but too much goes unburned out of a 4" barrel (I use it in my larger magnums). I like WW 231 but it is not available in my area for several years now. I detest Bullseye and Unique and haven't bothered to try newer powders.
(Ignore the highlighted powders - they were for a different comparison).
