Look at the chamber. It has a defect in it, with that larger diameter feature at the rear of the chamber.
The gun needs to have the chamber re-done. I don’t know if this was one of the rifles where the receiver and barrel are machined out of the same piece of steel; if it is, well then, there’s really no way to fix this short of boring out the chamber and soldering in an insert to make the chamber correct. That’s not a job I’d take on, because it would need a custom tool made (a counterbore with a pilot) to take out the existing chamber, and the value of this gun doesn’t make me eager to pay for such a tool to be made.
If the barrel could be separated from the receiver, then it’s a matter of setting the barrel back, which would mean putting the barrel into a lathe, cutting off the rear end, running the threads forward on the tenon and then re-cutting the groove for the extractor.
For the value of this rifle ($300 if it were a 100% example), there’s little chance the owner wouldn’t be upside-down on the gunsmithing charges vs. the value of the rifle itself.
If the barrel and receiver are one piece, could the old barrel be cut back to two or three inches? Then use the old bore as a pilot hole for threading in a new barrel.
