Didn't know that was a thing, but something about like that, yes.

.50 beowulf?

You could always get a revolver chambered for .50AE and use moonclips. And besides that the concept seems to be an answer in search of a question. There are a ton of established calibers to choose from that are all virtually the same when it comes to civilian carry purposes.

.50 GI with a rim?

50 special?
50 GI?
500 S&W magnum?
50 beowulf?

>50 GI?
Not a revolver round.
>500 S&W magnum?
High velocity makes lots of recoil.

That's a damn rifle round.
>50 special?
Closest thing to what I'm thinking.
