A projectile such as a paintball including a ball-shaped capsule and a round-shaped disc capable of facilitating accuracy of projectile travel direction is disclosed. The ball-shaped or substantial ball-shaped capsule, in one embodiment, having a head and a tail is able to store and deliver colored markers upon an impact between the projectile and an object. The round-shaped disc is positioned at a place so that allowing a portion of the round-shaped disc to extend above outer surface of the capsule. The disc is able to catch at least airflow when the projectile is launched. The round-shaped disc, in one example, uses the direction of the airflow to facilitate travel direction of the projectile.
