Which risk increases in early bronze cannons when rapidly fired in succession without cooling?

💡 Explanation

When rapidly firing early bronze cannons, thermal expansion mismatch occurs because rapid heating of the barrel lags behind the breech, leading to stress concentration, and increasing the risk of breech cracking. Therefore, breech failure is most likely, rather than projectile inaccuracy, misfires, or mount failure which are related to separate effects.
