Which limitation appeared during the introduction of cast iron cannons?

💡 Explanation

The cast iron process often created cannons with inconsistent material properties across the casting due to uneven CO2 cooling, therefore early cannons exhibited increased barrel bursting propensity, rather than improved performance, because stress concentrations accumulated exceeding tensile strength in weak zones.
