Shotguns neither fire bullets, nor do they use clips. The capacity for each shotgun will vary by model, load, and magazine. A Remington 870 off-the-shelf holds five rounds. The Saiga shotgun uses a detachable box magazine which may hold anywhere from five to 30 shotgun shells.

It all depends on the model.
the muzzle on a shotgun is where the bullets come out.

First, you probably mean cartridges, not bullets. Bullets are just the very tip of the cartridge. And you also probably mean magazine, not clip. Magazines can hold anywhere from 1 to over 100 cartridges, depending on the specific design.
The Clip that holds the bullets inside and automatic or any clip that holds bullets ready to load. http://www.minutemanreview.com/2008/09/clip-vs-magazine-lesson-in-firearm.html
I have been told bullets can be left in the clip forever. I'm would think a service weapon clip is replaced more often.

Note: The shotgun does not have "bullets" it has shells which are the casings and generally pellets inside the casing (of different gauge's); the number of pellets vary according to the gauge or size of the pellet. The smaller the pellet, the more there are of them.
