General mortar length should be?

Explanation:
General mortar length is set to six times the bore diameter to balance confinement, stability, and safe, reliable operation. This length provides enough space for the lift charge to develop proper pressure and push the shell up the tube so it clears the muzzle before the break charge acts, reducing the risk of misfire or damage to the tube. If the tube were shorter, the gases would be more confined, increasing back pressure and the chance of a misfire or tube stress. If it were much longer, there’s no real safety gain and it adds unnecessary weight and handling difficulty. Six times the diameter is the standard that offers adequate confinement and stable flight.
