There are two threads that have wandered a bit off topic and have begun to converage a bit so I am starting this thread to continue the discussion in a single place.
The first thread http://iaaforum.org/forum3/viewtopic.php?f=8&t=9174 has evolved into a discussion of when and why the DWM adopted the 9mm truncated bullet, and as a subset, the 7.65mm truncated bullet, as well as why Germany then went back to a RN bullet which had been DWM standard design practice before the Luger pistols.
The second thread http://iaaforum.org/forum3/viewtopic.php?f=8&t=9198 began with a discussion of which case 471 or 471A was first used for the Luger carbine load and when. John Moss posted a great set of carbine loads and the thread is now focusing on the bullets loaded in the 7.65mm Luger cartridges by DWM.
The following is the source data that I have. Might as well put it here for all to see. There are five basic documents. The bullet drawings from the DWM 1904 catalog and the DWM bulletand case logs copied from a master document about 1912 or 1913. I have also included the Luger bullets from the DWM 1911 catalog. There were multiple copies of these logs made (I have heard there were 6). They started as very close copies of each other but were updated independently afterwards so contain some different information so comparing them is instructive. I have copies of a case log that reportedly was sent to DJ magazine which also includes the 480 bullets, and the copies of both the full case log and bullet log that Fred Datig was given in 1956. The Datig and DWJ logs were obviously updated seperatly since the WWI time period. The images below are grouped by subject for easy comparison across the sources.
Although this is primarily a bullet discussion, the case logs show which bullet was intended for each case.
7.65mm / DWM 261 Bullets - 1904 Catalog
7.65mm / DWM 261 Bullets - Datig
7.65mm / DWM 471 cases - Datig
7.65mm / DWM 471 cases - DWJ
7.65mm & 9mm bullets-1911
9mm / DWM 278 Bullets - 1904 Catalog
9mm / DWM 278 Bullets - Datig
9mm / DWM 278 Bullets - DAJ
9mm / DWM 480 Cases - Datig
9mm / DWM 480 Cases - DAJ
I will post some of my quesitons tomorrow. It is getting late so I will leave all these here for now.
It would be a great deal of help if some German speaking member can post the translations of the various notes in the DWM logs for those of us who are language impared!
