Maybe APFSDS penetrator fins

What sort of material and how heavy? Grenade, lightweight/plastic or thin metal, mortar significantly more robust - aluminum or steel, penetrator much heavier, steel or alloy. Yours looks pretty lightweight, possibly plastic? Large for grenade fins though.... More photos.

yes made from a hard lightweight plastic - guess must be rifle gren as plastic fins on a mortar round would melt in tube right?
