I wouldn't count on it. The Auto Rim's rim (.516") is 0.004" wider than the .45 Colt (.512"). You may find .45 Auto rim brass manufactured small enough that it still fits, but then you still have the fact the case body of the Auto Rim is smaller than that of the .45 Colt. The .45 Colt case body is 0.480" wide, maximum, front to back. The Auto Rim is slightly tapered, being 0.476' maximum at the base and 0.472" maximum at the mouth. So this is potential for a pretty loose and poorly aligned fit in the .45 Colt chamber.

Even if you got rims small enough and the brass to fit the chambers, it stands a good chance of cause a lot of leading in the gun. That's because the shorter case may let the bullet lie at an angle in the cylinder (always bad for accuracy) and have gas bypassing the base until the bullet makes it to the throat.

Anyway, what you're asking about sounds a little like putting a 6-32 screw into an 8-32 tapped hole. Good fit won't be part of the picture.

The AR rim is considerably thicker, too. Doubtful you could ever close the bolt.

Unless you just happen to have a bucket full of the Auto Rim brass , why would you want to ? And even if you did , I suspect you could do some trading ( or sell it ) to come up with .45 LC brass ?

Bought new , I suspect .45 LC is cheaper , any way .

Is this one of those deals where you have a wheel gun that shoots the Auto Rim ammo ?

God bless
