I've only used their .32 H&R Mag 100 grain hollowpoint. I bought this for use in my S&W titanium snubby. It was much faster than the Federal 85 grain hollowpoint offering.
I shot some of the GA in my Ruger Single Six .32 and got some phenominal groups. The best was about 2" at 50 yards from a bench rest. That is not a misprint: 2" at 50 YARDS.
I emailed GA, and to my surprise, they told me what the load was. Unfortunately, it was a non-canister grade (not publicly available) powder they were getting from Accurate Arms.
I'm an avid handloader, but I've never gotten any of my .32 mag handloads to shoot as accurately as the GA stuff.
My limited experience with GA was first rate.
