The shotgun sometimes has never ending ammo and can shoot as fast as you can click the mouse button.

Not sure how to do it. It happens sometimes when switching between axe/weapon, chopping wood, reloading etc in quick succession.
It also can not be dropped or swapped for another item by drag-and-drop. The only way to put the shotgun away is to bind another item to a quickslot and press that key to switch. Then it will be put on your back.
It is also impossible to drag the shotgun to a quickslot or to the hands. The only way to get it into hands is to eject the ammo - then it moves to hands, with the ammo both in the backpack and visible in the shotgun.
There is no way to drop it on the ground.
