A gunsmithing question.

[Gussy]

Bought a Browning medallion 22 hornet on the net. The barrel has some pits which I can easily live with. However, the throat is pretty bad.

Question, can the barrel be set back a couple threads and rechambered to clean it up and retain the factory markings?

Would a "throating", like paper patch chamber work?

A new factory barrel is still available, but, in the white and no markings.
