Given Miller's comment concerning potential confusion over the term "ahead of the forcing cone" (which direction is "ahead"?), it's probably better to use "end of the chamber" as Hugh Lomas did in his post.
Miller, I have the same book you cited. Forgot how much good information it contains! However, mine is the 1972 edition, and it looks like they may have edited out the information you posted on wall thickness, etc. Can't find it anywhere in the shotgun section. Where did you find that reference in your book?
