.013 is HUGE in barrel diameter. .002 is tolerable in some applications. The action is relatively weak (compared to a Mauser). Normal working pressures do not mean a hill of beans when you are swaging a bullet down .013". I would not be surprised if the "normal" pressure of a .308 went to 80,000 PSI through that barrel. That is high for a proof load. If .308, even one round, was fired through a 7.35 X 51 barrel, I would NEVER shoot that gun again, with any ammo. Cracks, invisible to the naked eye, could let the whole thing loose at ANY time.
