That looks similar to the round that I recovered after it detonated on the bench. I think all of the brass case was present and accounted for. The primer was gone, along with the anvil, and some of the plastic or styrofoam package was also gone. If I find it, I'll post a pic.
A quick look turned up some other range ammo abnormalities that I'll post pics of in a new thread. I have a backwards primer, one round with no flash hole (that one really bound up the gun) and a case rim rolled under the bullet. All of these have one thing in common-budget price (at the time).
