I have chronograph data where I have shot AA#5 in 38 Special, 357 Mag reduced loads, (38 Special equivalent in 357 cases), 44 Special, 45 L Colt, and 45 ACP. Accurate Arms #5 works well once you develop your own data. Some of the data in the Accurate Arms manuals are so far from reality, that the difference between what they claim, and what I see over a chronography, is mind boggling.
Anyway, shot up a lot of 45 ACP rounds with the stuff. It functions the pistol and shoots well. So, what's not to like?
My goal is 800 fps in a 5 inch barreled 1911 with a 230 grain bullet. That was the original velocity of the 1910 developmental cartridges, which were loaded with 5.0 grs Bullseye and a 230 FMJ.

Shoots well enough at spitting distances.
