My understanding is that the exit bore of the barrel must not be larger than the entry bore of the top section. It can be equal or narrower.

My conjectural explanation is that you don't want the air column to hit an obstruction as it enters the clarinet itself. A barrel that ends equal to or narrower than the clarinet's entry provides a straight pathway into the clarinet. If the clarinet bore is narrower, the air flow is obstructed around the periphery and turbulence will result in the air column. But that's just a guess - someone with a stronger physics background might weight in with a different answer and explanation.

I do know that none of my working barrels have exit bores larger than the entry bore on my clarinets. As I remember, they're all narrower.
