Which disadvantage limited cannon effectiveness after repeated firing utilising cast bronze barrels?

💡 Explanation

Cannon bores progressively enlarged with repetitive use because work hardening induced plastic deformation decreased yield strength via strain accumulation; therefore bore diameter expanded more readily, rather than leading to catastrophic cracking.
