Armor Piercing bullet

Steel bullet, white plastic cup.
diameter :
of steel part : 7.55
of plastic part 7.72
It must be for a .30 ctge.

I think it is from Belgian origin.

Has anybody info on this ?


10- 15 years ago I picked up several of these “bullets” together with some 15mm, 15.5mm bullets and cases on a militaria meeting in Belgium. The seller told me he had these from a scrap dealer Who picked up with FN. Later I spoke a technician from FN who told me this particular bullet was used for ballistic test. My bullet was .50 caliber, never seen in.30 caliber I still have one specimen. Wishes, Jan

Thank you for the info
