My 2nd Edition "Modern Reloading" indicates of cartridge drawings that maximum allowable dimensions are specified, allowing for the cartridge to fit "any standard chamber". Per that information, 1.135 is the maximum overall length according to the book for 40 Smith and Wesson cartridges. A 'MIN OAL' or "Minimum Overall Length" is listed for and varies by each type of powder and bullet weight. I would suggest that you go off of the data you're using from a reloading handbook, and stay above the minimum overall length for the specific powder / charge / bullet you're loading, and below the maximum overall length of 1.135.
