If you were super careful and lined up everything extremely precise, it may be possible to shoot it out with another rifle of same or smaller caliber also. I've never tried it or know anyone that has, but theres no reason it wouldn't work.
It just hit me, you should take the bolt out of the gun with the stuck case, so it and the bullet from the other gun can exit the rear of the action. And wear ear plugs. Safety first.
