for anyone interested, here is a chamber from a friend's .45-70 M74 Sharps. It is quite the same as any other original Sharps chamber including the M78s (Borchardts)in just about any caliber. And a number of reamer drawings have been made to cut these chambers in a variety of different calibers, including .40s. You could easily borrow/rent or buy such a reamer with a little effort and prowling on the Shiloh forum.
