I know the round balls are .454 but I had ot size bullets to .452 before they would fit. Pure plumbers lead mind you. I made up some .458" Lee 340 gr. RN and some SSK 270 gr. FN that I think were .454 and sized both to .452.
The 340 gr. would slide out of the cylinder on the second shot in recoil. They went about 750 fps with as much 777 as I could get under it and make fit. The 270 gr. ran 900 fps with a .44 Special or .41 Mag. case level full used as a measure. (Both have same capacity). That's what I used to shoot that little hog. It BARELY had enough to get into the inner cavity. The lead no doubt mashed out and dumped all it's energy. The C&B is no cannon. I think round balls traveling faster would penetrate better, not sure, just a hunch.
I have sized .410" to .401 but that is about all I can manage. Beyond that the bullet is badly distorted and becomes it's own identity. Jacketed, the bullet cores can pinch and protrude. But in theory you could keep on and "swage" to whatever your had in mind.
I have two sets of the old swage dies for common presses. One is .358" the other is .41. A tinker's delight.
