About all I might add is that the musket had adaptions for bayonets. The Bess I had used the bayonet lug as a front sight. I mention this because bayonets were a primary weapon when the smoothbore musket was used. There were also critters called smooth rifles, which were guns built like a rifle with a heavier barrel and sights. Quite commonly they seemed to be smaller bores.
To confuse the issue more, you had terms like fuke, fusee and fusil which seemed to refer to lighter weapons. For instance, is a Northwest trade gun a fowler
Referred to in literature as a as a fuke or fusee. Lightweight officers muskets were commonly referred to a fusils.
Nothing wrong with what Nate says, just that termonologies over the years get interesting. For instance they had short rifles and carbines
