making the recovered drill rifle shoot..once again.

breaching washers dont work very well with 03,s 17,s Krags or others with square threads, as the crush is on the shoulder, and not the threads.
getting headspace done with a washer would be an day long trial and error.
this was just to sqaure the face, and remove the raised area from the heat of the weld.

Yes, that is why you make a crush type washer and then dress it to the barrel on the lathe after it is brought to final index. The receiver looks like it has been rolled with a swaging roller.
