DWM's MINIMUM OAL for the round nosed bullet was the same as today's SAAMI MAXIMUM OAL of 1.169 inches, the principal reason for the Luger's less than shining reputation for reliability since ALL factory loads are below the original minimum OAL. (I'd like to know who the bright boy was who decided to shorten the cartridge.) I may have the specs for the truncated cone around somewhere, I'll have to look.
