I believe the cut for ACP with moon clips is the same as the Auto rim cut. The Auto Rim was designed to be a rimmed cartridge to substitute for ACP/moonies.
AR brass is meant to do away with the clips that are only used for rimless .45 ACP. Clips on AR (if you could get them on) would make it too thick and you wouldn't be able to close the cylinder.
The moon clips are for 45acp to be used in the revolver. The auto rim round doesn’t use a clip. I was wondering if they can use either a Acp round with clips and a ar round in the same cylinder.
