In the Palace of Karnavati, Vijay is designing the outline of the projectile with a serious expression on his face, As for why Vijay's face is so serious? Well, that is because he decided to make these projectiles both with armour-piercing and exploding properties. Drawing inspiration from multiple weapons of war, it was his own design idea, incorporating his knowledge of fluid mechanics and aerodynamics.
First, for the material, Vijay chose to use high-carbon steel, similar to the inner wall of the barrel. The projectile's shape is elongated with a pointed tip for penetration, and the base is hollow to contain a more substantial explosive charge. On the outer surface, he added some helical grooves in order to act like a screw when it hits the target, rigidly lodging itself into the target.
