Powder-actuated tools come in high-velocity and low-velocity types. In high-velocity tools, the propellant charge acts directly on the fastener in a process similar to a firearm. Low-velocity tools introduce a piston into the chamber. The propellant acts on the piston, which then drives the fastener into the substrate.
Break-action shotguns, double rifles, and combination guns typically have an extractor that pushes out the casings when the action is flexed open. Most modern extractors are forceful enough to completely eject the casing from the gun (i.e. integrating the function of an ejector), but some require the user to manually remove spent cartridges.
