Accurate Arms says that AA#5 is there most popular powder. How many of you have used it and for what cal. Please give your opinion. Is it really this popular ?
Works fine in the .45 ACP. It's just a Unique type powder or close to it. I think it might be a military surplus powder. Have several pounds that was purchased 4/5 years ago and it sure doesn't look like the current stuff.
I use it on all my handgun loadings with the exception of heavy .357, .44 mag, and .45 long colt loads for which I use AA#9. In my opinion, AA#5 is as versatile as unique without being nearly as dirty.

I find it to be very similar to Unique in burning rate and versatility, but it is a spherical powder and meters much better from my RCBS Uniflow powder measure.
Not only is it very good in .45 and 9mm, but it has "stuff" in it to suppress muzzle flash. That is what that green stuff is on the area in front of you when you shoot and in your pistol. Very good powder for .38,9mm,40, and 45. Ku-dude
I use it for .32 H&R Mag and .45 ACP. Works well, accurate, AND - a big plus - it meters great in my Auto-disk ! I've been using Titegroup for hese calibers, but it is tougher to meter. The #5 also puts more powder in the case than Titegroup, getting it closer to a fuller case.
