There exist a small number of German WW II steel case loads and separate
bullets produced by RWS with grooves around the bullets. These bullets are
magnetic and appear to be sintered iron. A note with the rounds indicate they
may be cast bullets, but that is not obvious from the bullet’s appearance. The
cases for these rounds have normal dnf headstamps.

The first cartridge below is headstamped dnf  St+  6  42 and the grooves on the
truncated bullet are clearly visible through the case. The bullet has a gray
“sintered iron” finish. There is also a cartridge loaded with a round nose bullet
with two grooves visible above the casemouth which also has a gray “sintered
iron” finish. The case is headstamped dnf  St+  9  44.

Finally there is a bullet which is similar to the one above, but with a cadmium
coating giving it a unique color finish. There are two loose cadmium coated
bullets known in collections and a loaded cartridge with this bullet is reported to
exist. It apparently is headstamped dnf  St+  9  44.
Until recently no documentation on these cartridges has been encountered, but Rolf
Foerster sent me a copy of the following two drawings, one of which identifies the 7.92
mm and 9mm bullets in production, and the other which illustrates experimental bullets
designed to same lead. This second drawing illustrated below identifies the bullet  
above as the "08 WE". Rolf tells me the “WE” means Weich Eisen or soft iron. The
caption indicates a million such bullets were made, yet only three examples are known!
What happened to the rest of them. At the time of the drawing it appears that none of
the WE bullets in 7.92 were in production, nor were the other 7.92 bullet designs
intended to save lead.
