Well guys I found the hatcher piece I was thinking of. It is not a study or a book - it is a textbook and long out of print. You can find it at rare book stores but it is not cheap. The link shows the complete title and the chapter on ammunition and ballistics. I think the guy that got 120mm's copy of the his notebook must have gotten mine as well because I cannot find it anywhere. Oh well, if you ever get the chance it is a good read and the man was a genius. He was a major when he wrote this book.
