Within early bronze cannons, which risk increased due to repeated firing?

💡 Explanation

With repeated firing rounds, cyclic stress induces fatigue cracking due to work hardening within a bronze cannon barrel, exceeding its yield strength. Therefore barrel wall fatigue cracking results, rather than propellant change, thread issues, or projectile deformation which require other failure mechanisms.
