That happens when cheap ammo is being used.. What happens is that the metal casing on the shell splits causing it to expand inside the barrel there for getting stuck inside the barrel.. The easiest thing to do is to pull the pump and at the same time insert some sort of rod inside the barrel to push out the empty casing.. I had that happen to me and I took it to a gunsmith and thats what he did.. Then it happend again so I fixed it my self.. good gun, cheap or possibly old ammo..
