I read through this post several times trying to understand the final disposition and am still frustrated. The OP says he tried several times to fire the dud round. Was he able to rack the slide to re-cock the striker or did he merely pull on a dead trigger? Now that he has the bad round out of the gun and can see the mess on the primer, is in fact the primer live or dead? That's important because if the primer is dead it is either from the original round and was failed to be punched out, or it was a defective new primer. It would be relatively easy to see if the round was disassembled. One way it was Freedom's fault, and the other way it was the primer vendor's. The teardrop shaped indentation on the primer looks like that from a fired round, indicating that the original primer was left partially in the case, explaining its protrusion. Such a round would wedge tightly between breech face and barrel. If this ever happens to me I'll try gently tapping down on the barrel block with the piece aimed in a safe direction. Much more mechanical advantage on that stuck round than trying to cam the barrel down with the locking lug cam. I would also wonder if the firing pin/striker assembly is in good order with a good return spring in a clean hole in the slide. Were it not, and protruding above the breech face, this kind of thing could happen.
I wish I knew what went wrong. Frustrating.
