The following three drawings are of experimental Polte subsonic
(Nahpatronene) loads for use with silencers. The production Nahpatronene 08S
by Polte has a green lacquered steel case and a 150gr lead core bullet. Two of
the cartridges illustrated are subsonic loads using the standard 124gr lead core
bullet and the standard iron core (mE) bullet. The final load is described as the
"Wolff: and has a bullet with a lengthened steel core which extends beyond the
base of the bullet. A more complete set of drawings is available in the German
Drawings file (link above). Note that drawing 9G-7 is titled mE indicating an iron
cored bullet, but the bullet illustrated is clearly has a lead core.
No examples of these loads are known.
Any additional information would be greatly appreciated
