Winchester 1917 way off

[Doco overboard]

Sometimes a bend can be easy to see in the right light. If the error is that much at say 25 yards that it cannot be corrected by drifting the F/s nearly off its base its more than likely bent pretty well.
Look through it at a strong light and the bend can be seen directly opposite by the shadow it makes inside the bore. Once you see the shadow that's cast off, rotate back and forth to pare the affected area down.
I just went through the very same thing with a take off no4 barrel.
Next step is to do what BAR says so I can try to save it for something else and learn.....
