In firearms, a blowback system is generally defined as an operating system in which energy to operate the firearm's various mechanisms, and automate the loading of another cartridge, is derived from the inertia of the spent cartridge case being pushed out the rear of the chamber by rapidly expanding gases produced by a burning propellant, typically gunpowder.

Rebated-rim cartridges are known to be used on firearms using advanced primer ignition (API blowback) for its operation, notably autocannons such as the 20 mm Becker/Oerlikon series. [1] API blowback firearms have straight-sided chamber walls as possible (and sometimes slightly bottlenecked) to contain the cartridge and allow a deeper chambering.
In forensics, blowback is the vacuum effect created in the barrel of a firearm when it is discharged. After the weapon is fired, air races into the barrel once the bullet has left the muzzle. This vacuum can pull in trace amounts of materials from the environment.
Simple blowback action is simple and inexpensive to manufacture, but is limited in the power it can handle, so it is seen on small caliber weapons such as machine pistols and submachine guns. Lever-delayed blowback, as seen in for example the French FAMAS assault rifle, can also handle more powerful cartridges but is more complicated and ...

According to Newtonian mechanics, if the gun and shooter are at rest initially, the force on the bullet will be equal to that on the gun-shooter. This is due to Newton's third law of motion (For every action, there is an equal and opposite reaction). Consider a system where the gun and shooter have a combined mass m g and the bullet has a mass m b.
