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.

Wow. Those guns must command terrific prices from collectors now.
