Do not put anything else metal in there. You'll only succeed in damaging your bore! Call your local smith he'll know how to get it out.
Time to find and make acquaintance with the closest smith then! Added to the to-do tomorrow....
If I got it started from the chamber with a dowel would it pull through more easily? It's only a 5.45 so any dowel would be a thin one. And the receiver prevents straight access to the barrel from the rear.
Is a sub 16" barrel legal?
I have few metal-working tools and this is my only semi-auto rifle, although I have a Hi-Point carbine for back-up defense at least, I'm not willing to risk modifying the barrel and ruining all accuracy permanently. I have lots to try before I'd do that, and I'd seek professional help instead of going there, sorry.
