Colt made New Service in 455. I think some Single Action Armys were too.
Smith made some of their N frames in it.

Wow. Those guns must command terrific prices from collectors now.There is an interesting thing about the SAA made for .455 and .476. The .45 Colt was made with a very small rim so it would fit into a cylinder that was made on the same tooling and only a bit larger than the .44 New Model Army cylinder. But the .455/.476 has a normal size rim (.530" vs .505" for the .45 Colt). How did Colt do that?
First, they enlarged the frame window to take a slightly (.021") larger cylinder. Then they bored the chambers at a slant (convergent), so the rounds sit a little skewed in the cylinder. Reportedly, the firing pin hits off center, but the guns work OK.
