I have used a couple of pounds of Autocomp and like it in the 45 acp. I have also been using CFE pistol and the same charge of one weighs the same as the other from my powder measure and scale. I'm not sure why people seemed to be concerned about how clean a powder burns. if you shoot a lot the gun is going to get dirty. some powders may burn a little cleaner at the high end of the pressure range (Unique for one) but it is still dirty
