First of all, it is not about the size of the gun, so much as it is about the volume of fire. Union Monitor style ironclads were equiped with 11 and 15 inch guns, yet proved to be very ineffective at shore bombardment because their rate of fire was very slow. The New Ironsides, a U.S. ironclad frigate, carried twenty guns and was much more successful at shore bombarment. The monitors guns were heavier, but the New Ironsides had more of them.
The New Ironsides problem, and the problem with most larger ships, is that their draft was too deep to get close enough to be effective, and the Monitor style ships that were shallow enough were outgunned by most shore batteries.
Also, a note on the 5 inch gun. The 5 inch gun was the standard armerment for WWII destroyers and these ships DID conduct shore bombardment. In fact, US destroyers mounted 5 inch guns up through the Spruance Class launched in 1975, ships of which are still in service today.
