.38 Super brass and .38 Colt Auto (.38 ACP) brass are, to all intents and purposes, identical. I load for a Colt 1902, Astra 400, and Star Modelo Super, and use the same batch of brass for all. Of course, I load them all to different levels, and simply note on the box label which pistol they are for. BTW, the ACP should do well with a 125-130 gr bullet at about 950-1000 fps.
