.45 ACP in .45 Colt SA cylinders

[alukban]

I have a ton of .45 ACP brass but not as much in .45 Colt.

I would love to have a way to use .45 ACP rounds in my .45 Colt SA's without swapping cylinders. I was thinking of how to create a "mono clip" to do so but the measurements revealed that the clip would have to be only about 0.01" thick. and be easily removable for reloading the brass.

In a pinch, if only .45 ACP ammo/brass were available for a revolver with a .45 Colt cylinder, it seems that a knot of string (perhaps even floss) can permit expedient, reversible use of of the non-rimmed case.

For some reason this looks like a bad idea.

I kept thinking the same thing but also kept thinking it away, the more I thought about it.

As long as it doesn't jam the cylinder...

The string/knot may jam the cylinder if it is too big.

Otherwise, the rim doesn't really do much and that is why there are plastic moon clips and why you can use .45 ACP in dedicated .45 ACP revolver cylinders which are cut to index off the case mouth. The knot is just enough to hold case in place for the hammer strike.

If the knot does not hold and the cartridge is driven into the cylinder, ithe primer may not detonate (and nothing happens) or the primer does go off anyway.

Upon detonation, the rim does nothing. The case is thrust backwards against the frame face.

I've heard of using rubber O-Rings. But, haven't tried it.

My brother tried in a Rossi Ranch Hand .45 Colt levergun for function (did not actually shoot a live round) and he said it works single fed.

It extracts too apparently.
