Unknown bullet or something else!

this thing is made of two parts !

  • an hollow copper jacket , diameter 7.75 mm
  • a steel cap, also with an hole at the center, diameter 7.89 mm

Total length : 43.90 mm

What is it ?
A kind of gyrojet ? A bullet ?


I have no idea what it is, but it’s not a gyrojet. The single, straight port (hole) would not spin it, so…not a gyrojet.

Could it be a trench art component, perhaps the handle to a pen or a letter opener?

No, it is too new for that.
If I remember well, (I bought it fifteen years ago), it was from Belgian origin.
It is empty but the enveloppe is a lot thicker than a regular bullet
