Compare how different BB weights travel over distance from the same muzzle energy. The race animation runs in real time — the dashed markers show exactly where a heavier BB first catches up to the lighter one.

Assumptions:

• Zero metres above sea level, standard air density (1.225 kg/m³)
• BB diameter 5.95mm, drag coefficient 0.47
• Gravity and hopups are not real

Travel time race - 0 to 100 m

Real-time animation. Each time-to-target label appears at its 10 m marker as the BB passes it. Right column shows total travel time once a BB reaches 100 m. Dashed lines mark where the heavier BB begins arriving at targets first.
