Axel's chamber cast clearly shows the rim and end of the chamber while cordite's does not. Placing a straight edge on the photo of cordite's casting does not show any change in taper along the whole length that I can determine. It does taper somewhat just before the rifling begins but gauging this from a photo is difficult at best. The chamber in my black powder Hanquet cape rifle is much like cordite's and doesn't show a real end to the chamber, it just goes on into the rifling. I am only going to venture to say that this may not have been that uncommon back then.
I might also suggest trying to just run the case back into the die just far enough to hold the bullet tightly with the expander removed. With luck you may be able to bell the mouth with the regular die or make a tool for it. Putting the bullet in may be an issue though and you may have to do it by hand then straighten the bell in the sizer. This would allow you to use a larger bullet and not work the brass as much. I am sure one of the die makers would be happy to make a set as well. Mike or Sharps may have some suggestions.
Thanks, Diz
