It's just a metal tube?
Just a metal tube that has to be made to very high specifications and undergoes huge pressure every time it’s fired, they lose accuracy and then have a tendency to self destruct once they have fired too many shells
Just to add, thats due to the "rifling" - the metal spiral grooves cut along the length of the barrel which allow the shells to spin - which wears out under the immense pressure of sending a heavy lump of metal over large distances, losing both accuracy and velocity (can't fire as far) alongside the more obvious "barrel go boom" side effects.
Handheld infantry rifles, pistols, machine guns etc all have the same issue of barrels wearing this "rifling" out and losing accuracy, velocity etc so it eventually happens to all guns big or small once they fire enough rounds.
Rifling inside a barrel
Damaged rifling -
what happens next as the metal weakens - Russian Self-Propelled Artillery barrel exploded for example -
