Low-recoil shotgun shells, as the name implies, are designed to generate less recoil when fired. Recoil, often referred to as kickback, is the backward movement experienced when a firearm is discharged. This movement is a result of the law of physics that for every action, there is an equal and opposite reaction. In this case, as the shell is fired forward out of the barrel, the gun moves backward against the shooter’s shoulder or hands.
