Which limit existed when the Chinese first introduced iron projectiles with gunpowder?

💡 Explanation

In the Song Dynasty, mass adoption of gunpowder weapons encountered erratic projectile distances, caused by inconsistent grain size and composition affecting burn rate. This inconsistent deflagration meant unpredictable power transmission imparting less consistent impulse, therefore limiting effective targeting range, rather than projectile quality.
