Cubic boron nitride and carbon nitride, boron carbon nitride and metal borides armour piercing bullets

Cubic boron nitride armour piercing bullets.
 A full cubic boron nitride penetrator
 Maybe a design where it is fitted on a sabot.
 Or on a normal type of penetrator.
  With the pointed gem fitted on the penetrator.
   Partly inside the end of the penetrator.
  With 3 parts fitted near or against the point of the penetrator.
   Inside grooves so the penetrator is smooth.

Carbon nitride armour piercing bullets.

Boron carbon nitride armour piercing bullets.

And metal borides armour piercing bullets.
 If possible a sabot design. Or normal penetrator.

With the right designs.
And through testing.
