Yes you cannot use 45AR in a Redhawk due to the way the cylinder is cut for both 45 ACP on moonclips and 45 Colt. The raised rim around the outside that allows 45 Colt to head space without the moonclip would make the 45 AR stand off the face of the cylinder to far to shut the cylinder. If you want to use your favorite 45 ACP loads in your 45ACP/45Colt Redhawk but don't want to use 45 ACP brass and moonclips (and that is crazy talk as moonclips rule!) you can use 45 Cowboy-Special brass. It is a 45 Colt case cut down to the same length and internal volume as 45 ACP. Load it with 45 Colt shell plate and sizing die the seat and crimp with 45ACP/AR dies.
