German 9mm WWII sintered Iron?

German 9mm WWII sintered Iron, or something else?

The black color of the bullet marks it as “08 mE” (mit Eisenkern). Most of the lead core is replaced by a mushroom-shaped core of non-hardened steel (Eisen is German for iron) for the purpose of saving lead. Jacket shape is identical to lead core bullets.

Sintereisen (08 SE) do not have a jacket and look dull or even porous.

Here two pictures of German 9mm of 1943 and 1945, illustrating the different look. The “forty-fiver” on the right, is from “Sintereisen”. You can see a clear difference of structure of the two bullets.

Thanks you!
