Which consequence resulted from imperfect sealing of a medieval Chinese repeating crossbow's magazine?

💡 Explanation

Inconsistent sealing allowed varying propellant gas leakage, triggering inconsistent projectile velocities due to fluctuating internal ballistic pressures; this is gas dynamics rather than efficient propulsion; therefore, projectile consistency decreased because imperfect sealing allowed for energy loss, rather than optimal pressure.
