And, this is a very interesting project. </div></div>
Zirconium powder adds report flash for the shooter to see exactly where the round impacted, as the explosive is detonated by the pressure of the penetrator and the incendiary mixture impacting a HARD object (steel plate) and pushes the explosive charge and detonation through the other side, and the zirconium powder (also used in fireworks for a 'brilliant' sparkling effect) ignites on both sides with big bright brilliant report ensuring the shooter sees exactly where he hit. Remember, these rounds are meant to be used at ranges exceeding 1500m. They have no real effect however on soft targets (troops in the open) or earthen bunkers, as it does not allow reliable operation of the method of detonation, which requires impact upon a hard target.
Also, use at ranges under 300-400m will result in unreliable detonation, due to fragmentation of the rounds jacket before reliable operation of detonation system, though the big carbide penetrator will still do some damage.
