Pump action should be used by the safe hunter in the case of a hangfire when the trigger is pulled and the firearm does not discharge.
The empty case is removed, the piece is loaded, and it is cocked with the aid of a hand-operated lever that swings back and forth during pump action. Pump-action shotguns are quite popular since they can reliably handle any load that a shotgun can fire. These include birdshot, buckshot, slugs, breaching loads, and even flame-emitting Dragon's Breath rounds.
