I have three reloading manuals; Lyman, 49th edition; Hornady 7th edition; Lee 2nd edition. In trying to decide on a powder and load I've been studying all three manuals and find a lot of conflicting data. In several places I've found the starting powder weight in one manual to be higher than the maximum weight in another manual. There are also differences in OAL for the same powder load with the same bullet. The question is how to tell which is correct?
I attached one example for a 9mm, 115 gr, Hornady XTP bullet. Only data from Lee and Hornady are included because Lyman does not list the 115 gr XTP. The gray cells show the problems.
