I emailed Accurate Arms with the following request last week:
This is the response:Hello,
I am really just getting started using Accurate Powders, having used
other brands for over 20 years. Except that I have loaded AA#9 in the
454 since the mid '90's. I would appreciate any starting loads you
might recommend for the following caliber/handgun as I can find no
published recommendations on your website.
38-40
Colt SAA (Mfg. date 2008) 7.5" bbl
Bullet- Midstates Cast Plain Base 180 gr. RN (.401 dia)
(any recommendations for lighter, heavier or jacketed welcomed, though
my primary bullet will be 180gr Cast)
Powders requested: AA#5 and AA#7 and AA#9
Also request your opinion on which powder would be optimum. I figured
that #5 would be better for cast, and #9 would probably be to slow for
good results, would like to hear your input. If you feel that better
consistency would be offered by another powder in your lineup please
feel free to recommend which one.
I'm looking for velocities in the neighborhood of 800-850 fps, with 950
fps my upper limit.
Thanks,
Ed Henning

Barrel length: 6”
Powder: Accurate – No2.
Bullet weight: 180 grains.
Low Load: 5.4 grains (800 -875 Ft/p/sec)
Mid range load: 5.8 grains (900 – 950 Ft/p/sec)

It’ important to note that SAFETY is our prime concern therefore we strongly recommend.
1. TO ALWAYS BEGIN LOADING AT THE RECOMMENDED MINIMUM “START” LOAD.
2. If at all possible, measure the velocity and correlate with our data.
