Abstract: A device, and method for using the device, for extracting a large-caliber projectile jammed in a barrel of a weapon including a solid body having a diameter smaller than the caliber of the barrel and intended to be introduced into the barrel at the muzzle of the latter and then released in the barrel in order to impact, by inertia, the jammed projectile. The device is at least two radially expandable locking mechanisms, each able to move between a locked position in which it is applied radially against the inner wall of the barrel and a released position in which it is not applied against the barrel, the passage of the locking mechanisms from one position to the other by an expansion apparatus, the device includes a translation device enabling a first locking mechanism to be translated axially to a second locking mechanism.
