At a distance of 15 meters, pellets are generally considered more accurate than BBs due to their design and aerodynamics. The shape and material of the projectile significantly influence accuracy and performance, with pellets often outperforming spherical BBs in long-range scenarios. The discussion hints at the importance of understanding the mechanics of real firearms to grasp the differences between these projectiles. Participants encourage the original poster to explore these concepts further rather than seeking straightforward answers. Overall, the conversation emphasizes the technical aspects of projectile design and its impact on shooting accuracy.
