<strong>Bob,
The original 9 mm load of 124 gr at about 1050 fps was for the "Old Model" with the flat recoil spring. With the introduction of the new model and the coil spring, DWM started using two different springs in the two calibers and boosted the velocity a bit in the 9 mm. Still not +P+ of course. But some present day commercial stuff isn't all that spiffy.
In the 7.65 mm, no present day commercial load reaches the original velocity in a six inch barrel, let alone the 4.5 or 4.75 inch barrel the original velocity specs were taken with.
I'll have to start paying more attention to OAL in the 7.65 as well.</strong></font><hr /></blockquote><font size="2" face="Verdana,Tahoma,Arial,Helvetica,Geneva">Hi Unspellable:
For your 7.65, load to 1.173, and you will have a good day at the range.
I researched the original German language DWM commercial owner's manual, Die Selbstlade-Pistole Parabellum, for the "New Model", as well as, the specifications for the issue WWI ammo from Goetz's book, Die Pistole 08.
DWM says 310m/ps (1020 fps)and the Prussian War Ministry 327m/ps (1076 fps). I know of no faster "issue ammo" for the 4 inch Parabellum until Mauser's update project in the mid 30s. Personally, I feel the "hot ammo thing" has been wispered into reality over the years, and has no real basis in fact.
Also, about ten years ago, I shot some original DWM truncated cone 123 gr and tested it. The average for 7 shots was around 1043.
If there is something else in print regarding the original loadings for these pistols, please let me know where to get a copy.
Bob
